A significant proportion of the founders who come to me have been burned before. Not by fraudulent consultants, but by perfectly legitimate ones who delivered something that looked like consulting: a thick strategy document, a set of slides with market research, a list of recommendations. Then they left. Six months later, nothing had changed. The document sat in a drawer, the recommendations were never implemented, and the business was in exactly the same position, only lighter by several thousand pounds in fees.
When those founders find SGI, they are sceptical. They tell me this in the first conversation. “We’ve had consultants before, and it didn’t work.” They are not wrong to be sceptical. A lot of business consulting does not work, not because the advice is bad, but because advice without implementation support, financial modelling, investor-grade documentation, or accountability structure is not enough to change anything.
Here is the principle that shapes everything SGI does: a business owner does not need to be told what is wrong with their business. They almost always already know, at least in outline. What they need is someone to help them build the specific things that will fix it. A financial model. An investor pitch. A pricing framework. A customer acquisition system. A documented operational process. Things, not opinions.
This page explains exactly how SGI works: the methodology, the client journey, the deliverables, and the questions you should ask us and any other consultant before committing to an engagement.
Why Most Business Consulting Does Not Deliver Results
The consulting industry has a delivery problem that it rarely discusses openly. The traditional model, in which a senior consultant spends several weeks analysing a business, produces a report of findings and recommendations, presents it, and moves on, is structurally designed to generate billable hours rather than outcomes. The consultant is incentivised to be thorough. The client is left to implement the recommendations alone, without the financial models, investor documents, marketing systems, or operational frameworks that would enable implementation.
The second failure mode is the retainer that never produces a tangible output. A founder pays a monthly fee for access to strategic advice, attends monthly calls, receives emails with observations, and, after 12 months, cannot point to a single concrete thing that changed as a direct result of the engagement. The engagement felt productive. The business did not grow.
The question I recommend asking any consultant before engaging them is not “what will you recommend?” It is “what will you build for me, and what specific, measurable outcome will tell us both that it worked?” If the answer to the first part is vague and the answer to the second part is nonexistent, the engagement is likely to produce a document rather than a result.
SGI’s methodology is built around a different principle. We are a deliverable-first consultancy. Every engagement produces something specific and tangible, whether an investor-ready business plan, a financial model, a go-to-market strategy, a pricing framework, or a growth roadmap with implementation support. Our track record is measured in outcomes: an average 180% revenue increase for growth consulting clients, a 73% funding success rate for startups we prepare for investment, compared with a UK industry average of 13%, and over £250 million in capital secured for the businesses we have supported.
The Three Pillars of SGI’s Work
SGI’s services are organised around three core areas, each corresponding to a distinct set of business needs and client situations. Most clients initially engage us through one pillar, and many move across pillars as their business develops.
Business Planning covers the creation of investor-ready business plans, startup loan applications, franchise plans, visa business plans, grant applications, bank loan proposals, and specialist plans for complex or regulated sectors. These are not generic templates. They are bespoke, institution-grade documents built to withstand the scrutiny of specific funders: HMRC-approved lenders for Start Up Loans, Tier-1 VCs for equity rounds, UK Visas and Immigration for Innovator Founder or Start-up Visa applications, or specific grant-making bodies with their own evaluation criteria.
Startup Consulting covers everything a business needs from concept through its first significant funding round: business model development, concept validation, product-market fit work, investor-readiness preparation, startup strategy, and mentoring. This pillar is for founders with an idea or an early-stage business who need rigorous strategic and operational support to make it fundable and scalable.
Business Growth Consulting addresses the needs of established businesses that are growing but not as fast, profitably, or sustainably as they should. Services here include revenue optimisation, pricing strategy, customer acquisition, market expansion, operational efficiency, financial management, and turnaround work for businesses in distress. This pillar serves businesses with revenue from £500k to £100M, ranging from single-founder SMEs to mid-market companies with professional management teams.
The three pillars are connected by a common methodology: diagnose before prescribing, build rather than advise, and measure everything.
How an Engagement Begins: The Free Assessment
Every SGI engagement begins with a free 60-minute assessment session. This is not a sales call. It is a genuine diagnostic conversation, and its purpose is to determine whether we can help you, what help would look like, and whether the fit between your situation and our capabilities justifies a working relationship.
In that session, I will ask you direct questions about your business: where revenue comes from, what is not working and why you believe that, what you have already tried, what specific outcome you are trying to achieve in the next twelve months, and what is genuinely preventing you from achieving it. The conversation is substantive because I need enough information to give you an honest assessment, not a polished pitch.
At the end of the session, I will tell you one of three things. First, I will tell you there is a clear, specific way I can help you, explain what that looks like in practical terms, and outline what an engagement would involve and cost. Second, I will tell you that there is potentially a fit, but I need to understand your business better before recommending a specific engagement and proposing a diagnostic audit as the next step. Third, I will tell you honestly that based on what I have heard, SGI is not the right resource for your current situation, and where possible, I will point you towards something that is.
That third outcome happens more often than most consultancies would admit. I have turned down clients because their business model was fundamentally broken and no amount of consulting would fix it without a more fundamental pivot. I have referred founders to accountants when their primary problem was tax and compliance rather than strategy. I have told businesses seeking funding that they were not ready, and that pursuing a funding round at that point would waste their time and damage their investor relationships. Honesty in the assessment phase is more valuable to a client than a comfortable engagement that produces nothing.
The SGI Diagnostic: Understanding Before Prescribing
When an engagement proceeds beyond the initial assessment, the first formal phase is always diagnostic. Before we recommend anything, we need to understand the business with sufficient precision to be confident that our recommendations will actually work.
The diagnostic covers different territories depending on the engagement type. For a growth consulting client, it involves a revenue funnel audit examining where customers are being acquired and at what cost, where prospects are dropping out of the pipeline and why, what the pricing structure looks like relative to market position and customer value, and what the gross margin profile looks like by product line or service type. For a startup seeking funding, preparation involves stress-testing the business model, validating unit economics, assessing the competitive landscape and moat, and reviewing the founding team’s capabilities against what investors in the relevant sector actually back.
The diagnostic output is an honest picture of the business: its genuine strengths, the specific areas where intervention will yield the highest return, and the structural rather than tactical problems that require a different kind of attention. I have sat with founders who came to me for marketing advice and left the diagnostic session understanding that marketing was not their problem. Their pricing was such that even with twice the leads, they would not achieve the growth they wanted. Fixing the wrong problem is expensive.
One of the outcomes I am proudest of in our diagnostic process is that it prevents bad engagements. A Cambridge-based FinTech that came to us seeking investor readiness support had, on the surface, a compelling product. Our diagnostic revealed that their SME customer segment had 23% annual churn and a 34-month Customer Acquisition Cost payback period, unit economics that no serious investor would back. Rather than preparing them to pitch a broken model to VCs and watching them fail, we recommended a strategic pivot: focus exclusively on their Enterprise segment, where retention was 87% and average contract value was £67,000. They rebuilt their financial model to reflect those economics. They secured £1.8 million at an £11.2 million valuation, a 2.8x increase on the lowball offers they had been receiving. They did not change the product. We changed what they were selling it to, and how they presented the evidence.
Phase One: Audit and Strategy
The first formal phase of a growth consulting engagement is the audit and strategy phase, typically running two to three weeks, depending on the complexity of the business. This phase produces the foundational deliverables on which subsequent work rests.
The revenue funnel audit examines every stage of your customer acquisition and conversion process, from first awareness to closed sale, and identifies where the most significant friction or leakage exists. Most businesses discover that their largest revenue opportunity is not in acquiring more leads but in converting a higher proportion of the leads they already have, or in retaining existing customers more effectively. A professional services firm I worked with was losing 30% of proposals at the contract stage. Not because of price, but because their contract terms were confusing. One afternoon of simplification work unlocked an additional £180,000 in annual revenue without spending a single additional marketing pound.
The pricing review assesses your current pricing against your market position, your cost structure, and what your customers actually value. Pricing is the single highest-leverage lever in most businesses. A 10% price increase, holding volume constant, typically improves profit margins by 30 to 50%. Yet most UK SMEs price based on cost-plus logic, competitor matching, or what they charged three years ago, none of which relates to what customers are willing to pay for the value they receive.
The competitive positioning work produces a clear picture of where you sit in your market, what genuinely differentiates you from alternatives, and whether your current messaging communicates that differentiation in the language your customers use rather than the language your team uses internally.
The output of Phase One is a 90-day growth roadmap: a prioritised, sequenced action plan that addresses the highest-impact opportunities identified in the audit, with clear owners, timelines, and success metrics. This is not a general strategic direction document. It is a specific operational plan for the next ninety days, detailed enough to execute without me in the room.
Phase Two: Implementation
The second phase is implementation, and this is where SGI’s model differs most significantly from conventional consulting.
We do not hand you a strategy and leave. For clients on our Growth Engine and Market Dominance tiers, Phase Two involves working alongside your team to implement the changes identified in the strategy phase. This means attending sales calls if we are optimising conversion, reviewing and editing marketing assets rather than providing feedback on them, building the financial models rather than specifying what they should contain, and troubleshooting problems as they arise in real time rather than diagnosing them in retrospect at a monthly meeting.
The practical shape of implementation varies by engagement type. For a startup preparing for a funding round, this means building the investor-ready business plan, the three-statement financial model, the pitch deck, and the investment memorandum. We do not advise on what they should contain; we produce the documents to an institutional standard and then work with the founder to ensure they can defend every number and every claim to the most sceptical investor they will meet. For a growth consulting client, it means we do not just recommend a customer acquisition strategy; we build the framework, help set up the systems, review the first outputs, and refine the approach based on actual results.
Monthly KPI reviews are a formal part of every Phase Two engagement. Each review covers: actual performance against the 90-day roadmap targets, the specific interventions made in the preceding month, what the data shows about what is working and what is not, and what adjustments the evidence suggests. These are not reporting meetings. They are decision-making sessions in which the plan is updated based on real-world feedback rather than maintained in the face of evidence that something is not working.
Phase Three: Scale and Embed
The third phase is about making the work sustainable without ongoing external support. The goal of a consulting engagement is not to create permanent dependency on the consultant. It is to leave the business in a state where the systems, processes, and capabilities installed during the engagement continue to function and improve after we leave.
In Phase Three, the focus shifts from building to embedding: documenting the processes that have been developed, training the internal team to manage them, automating what can be automated, and establishing the measurement cadence that will tell the leadership team whether things are on track without needing an external consultant to interpret the data.
This phase also addresses the strategic horizon beyond the immediate engagement. If Phase One and Two addressed the revenue ceiling, Phase Three looks at the next constraint: whether that is leadership capacity, technology infrastructure, market expansion, capital requirements, or something else. The output is a roadmap for the next twelve to eighteen months that the business can execute independently.
The exit criterion from an SGI engagement is specific: the business can demonstrate measurable improvement in the metrics we identified at the outset, the systems we built are operational and understood by the internal team, and the leadership team has the capability and tools to continue improving without external support. That is when our work is done.
What SGI Builds: The Deliverable Map
Because transparency about what clients receive matters, here is a practical overview of the specific outputs produced across SGI’s three service pillars.
In the Business Planning pillar, we produce investor-ready business plans built to the specific standards of the funding body in question, whether that is a UK Venture Capital firm, a Start Up Loans Company assessor, a bank’s credit committee, or the Home Office for visa applications. We produce pitch decks with the narrative architecture that UK investors respond to: Problem, Solution, Market, Traction, Team, Ask, in a structure that makes the “why now” question impossible to ignore. We build three-statement financial models (Profit and Loss, Balance Sheet, Cash Flow), fully integrated and stress-tested against multiple growth scenarios. We produce investment memoranda for investors who require more than a pitch deck: a deeper document that covers market analysis, competitive positioning, unit economics, and the use of funds in detail.
In the Startup pillar, we produce business model documentation, product-market fit validation frameworks, market-sizing analyses using a bottom-up methodology, go-to-market strategies, and the complete investor-readiness package described above. We also provide mentoring, which means a regular, structured relationship with a senior practitioner who has worked with the specific challenges the founder is navigating.
In the Business Consulting pillar, we produce growth roadmaps; pricing frameworks with implementation guidance; customer acquisition systems; revenue funnel analyses with specific, identified improvement actions; operational efficiency audits and redesigned processes; and financial management frameworks, including cash flow models, unit economics dashboards, and funding strategy documents.
Who SGI Works Best With
Transparency about fit serves both parties. SGI works most effectively with clients who share three characteristics.
The first is a genuine commitment to implementation. The businesses that achieve the best results from an SGI engagement are those where the leadership team treats the work as an operational priority, not as an outsourced activity that runs in the background. We do the building, but we cannot do the internal selling, staff management, or execution decisions that only people inside the business can make.
The second is openness to challenge. Our diagnostic process and our monthly reviews will sometimes tell you things you do not want to hear. If a business model’s unit economics do not support the growth ambition, we will say so. If a pricing structure is leaving significant margin on the table, we will say so. If a marketing strategy is generating the wrong kind of leads, we will say so. Founders who need to be agreed with will find SGI uncomfortable. Founders who need to be told the truth will find it valuable.
The third is business stage readiness. SGI works with businesses across the full spectrum from pre-revenue startups through to established mid-market companies, but we match the engagement type to the stage. A pre-revenue founder needs validation support and business plan preparation, not a six-month growth consulting retainer. A £20 million turnover business in operational distress needs turnaround consulting, not startup strategy advice. The assessment session is designed in part to ensure that the engagement we recommend is the right type for where you actually are.
There are also situations where SGI is not the right resource. If your primary need is bookkeeping or routine accounting, you need an accountant. If you need a creative advertising agency to run paid campaigns, you need an agency. If your business faces a legal challenge, you need a solicitor. We work alongside these professionals regularly and maintain relationships with trusted specialists, but we do not do their jobs.
The Track Record Behind the Methodology
Numbers matter. They are the only honest way to assess whether a consulting methodology actually works, rather than whether it sounds plausible.
Across our startup and funding preparation work, SGI-prepared clients achieve a 73% funding success rate. The UK industry average for closing a funding round, across all preparation methods, is 13%. That is a 5.6x difference, not in the business quality of our clients relative to the average, but in the preparation quality that converts good businesses into funded ones. We have helped our clients secure over £250 million in total capital from Tier-1 VCs, including Atomico, Balderton Capital, and Index Ventures, as well as Angel networks, Family Offices, and alternative lenders. Our clients typically close funding rounds 40 to 60% faster than the industry standard: three to four months compared to six to nine months, because the due diligence materials are comprehensive before the first investor conversation rather than assembled in response to requests during the process.
Across our growth consulting work, clients who fully implement our recommendations achieve an average revenue increase of 180% over the engagement period. The conditions for achieving that figure are a genuine commitment to implementation and a market that is not fundamentally contracting. The typical consulting return on investment, measured as revenue impact relative to consulting fees, ranges from 500% to 2,000%.
Behind these numbers are specific client outcomes. Jamaica Rum Vibes achieved nationwide Tesco distribution and 220% year-over-year revenue growth after an engagement that included brand strategy, regulatory compliance for alcohol retail, and a structured market entry approach. Planetary Processing, a Cambridge University spin-out, secured £1.02 million in seed funding from Blue Wire Capital, Cambridge Enterprise, and Creator Fund after we developed their commercial strategy and investor documentation. Zaghou Chinetti, a management consultancy, grew from a solo practice to a multi-consultant firm, achieving 400% revenue growth and 92% client retention following an engagement focused on service systematisation, client acquisition, and team development.
Starting an Engagement: What Happens Next
If you are considering working with SGI, the first step is a free 60-minute assessment. There is no obligation attached to it, and there is no sales pressure during it. The purpose is a genuine conversation about your business and whether we can help.
To make that conversation as productive as possible, it helps to come with clarity on three things: what specific outcome you are trying to achieve in the next twelve months, what you believe is currently preventing you from achieving it, and what you have already tried. You do not need a detailed brief or prepared materials. You just need to be ready for an honest conversation.
If the assessment confirms a fit, we will propose a specific engagement with clear scope, deliverables, timeline, and investment. You will know exactly what we will build, when it will be ready, what the milestones are, and how we will both know at the end of the engagement whether it delivered the results we set out to achieve.

Conclusion
The difference between consulting that changes things and consulting that produces documents is not the quality of the thinking. It is whether the thinking is attached to specific, tangible deliverables that the client can actually use, and whether the consultant remains accountable for the outcomes rather than disappearing after the presentation.
Every business I have worked with has had the raw material to do significantly better than it was doing. The constraint was never intelligence or effort. It was almost always the absence of a specific framework, document, system, or strategy that would have made the difference if it had been in place. Our job is to build that thing, whatever it is, to a standard that works in the real world with real investors, real customers, and real market conditions.
If you are looking for a thick report of observations, SGI is probably not the right fit. If you are looking for something that will actually change your trajectory, let us start with a conversation.

Frequently Asked Questions
How long does a typical SGI engagement last?
It depends entirely on the scope of work. A standalone investor-ready business plan or financial model typically takes four to eight weeks from start to delivery. A startup investor-readiness preparation programme, covering the full documentation suite, runs for ten to sixteen weeks. A growth consulting engagement at the Growth Engine tier runs six to twelve months. A Market Dominance engagement for a larger or more complex business runs twelve months or longer. The assessment session will clarify what timeline is realistic for your specific situation.
Do you work with businesses outside London?
Yes. We work with businesses across the UK, from Cambridge and Manchester to Bristol, Leeds, Edinburgh, and beyond. The majority of our engagement work is conducted remotely, which has no impact on quality, and we meet clients in person where the situation benefits from it, particularly for diagnostic sessions at the start of engagements.
What is the minimum size of business you work with?
We work with pre-revenue startups and sole traders at one end of the spectrum, and established mid-market businesses with turnover up to £100 million at the other. The relevant question is not size but stage and need. A pre-revenue founder needs startup consulting and business planning support. A £5 million turnover business that has hit a growth ceiling needs growth consulting. The free assessment is the right place to determine which engagement type fits your situation.
Do you guarantee results?
We do not make guarantees, because business outcomes depend on factors including your implementation commitment, your market conditions, and decisions that are yours to make rather than ours. What we do guarantee is the quality and completeness of every deliverable we produce. We also share our track record transparently: clients who fully implement our recommendations achieve an average 180% increase in revenue, and 73% of the startups we prepare for investment close their funding rounds. Those numbers reflect the honest outcomes of our methodology applied by committed clients.
Can you work alongside our existing advisers, accountants, or agencies?
Yes, and we often do. We work alongside accountants (we handle strategy and growth, they handle compliance and tax), alongside marketing agencies (we provide strategic direction, they handle tactical execution), and alongside legal advisers when an engagement has a legal dimension. We are explicit at the start of any engagement about where the boundaries of our work are and where another specialist should lead.
What makes SGI different from a business coach or a freelance consultant?
The primary difference is deliverable specificity. A business coach provides frameworks, accountability, and support for the founder’s own thinking. A freelance consultant typically provides recommendations in a specific domain. SGI produces institutional-grade documents, financial models, and strategic frameworks that are built to specific external standards, whether investor expectations, lender requirements, or regulatory criteria. We also provide implementation support rather than strategy alone, which means we remain accountable for outcomes rather than just for the quality of advice.
How much does an SGI engagement cost?
Our growth consulting tiers start at £500 for a Growth Audit (a two-to-three-week diagnostic and 90-day roadmap), £1,500 per month for an active Growth Engine engagement, and £3,000 per month for the Market Dominance programme. Startup and funding preparation work is priced by project scope and documented in a proposal following the free assessment. In every case, we expect the revenue impact of the work to significantly exceed the investment.
