Platform01 Consulting Group provides startup advisory services in the UK for founders building, scaling, and preparing their businesses for investment. From the first financial model and business plan through to investor engagement and Series A preparation, we provide practical financial, strategic, and commercial support throughout the growth journey.

Our team brings experience from the investor side, including Molten Ventures and British International Investment (BII). This perspective informs how we approach financial modelling, investor materials, due diligence preparation, business planning, and growth strategy.

With experience across the UK, UAE, and Saudi Arabia, Platform01 supports founders in London, Manchester, Edinburgh, Birmingham, and other UK markets, as well as international founders establishing or expanding businesses in the UK.

Advisory Built from the Investor’s Perspective

Raising venture capital or angel investment is one of the most demanding stages of building a startup. Investors assess more than the idea itself. They examine the business model, financial assumptions, market opportunity, traction, management team, scalability, and the quality of the information presented to them.

Platform01 works with UK startups at different stages, from pre-seed founders developing their first financial model to Series A companies preparing for institutional investors and more sophisticated due diligence.

Our approach combines business advisory services with practical financial and commercial analysis. Rather than treating a pitch deck, financial model, business plan, or investor data room as an isolated deliverable, we consider how each component supports the wider investment case.

The investor perspective is particularly relevant when preparing a company for external funding. Our professionals have experience working on the investor side at institutions including Molten Ventures and BII, providing exposure to investment analysis, portfolio reviews, valuations, and due diligence processes.

That experience informs the way we approach every engagement: financial models are structured around transparent assumptions, investor materials are built around a clear commercial narrative, and due diligence documentation is organised to help investors understand the business efficiently.

Why the Investor Perspective Matters

When investors review a startup, they typically look beyond headline growth figures. They want to understand how the business generates revenue, what drives customer acquisition, how sustainable the economics are, how capital will be deployed, and whether management has a credible plan for achieving its objectives.

Our advisory approach reflects these considerations.

When reviewing a financial model, we examine the underlying assumptions, revenue drivers, operating costs, cash requirements, and scenarios. When reviewing a pitch deck, we consider whether the investment narrative is clear and supported by evidence. When preparing a founder for due diligence, we focus on the information investors are likely to request and the areas where inconsistencies can create additional questions.

This is particularly important for founders seeking small business advisory support. Smaller and early-stage businesses often need access to senior financial and strategic thinking without maintaining a large internal advisory team.

Platform01 provides that support through individual projects as well as ongoing advisory arrangements.

Our UK Startup Advisory Services

Platform01 provides a range of startup advisory services designed to support founders from early-stage planning through fundraising and growth.

Pre-Seed through Series B · CFA-Grade · Investor-Ready · Built for Due Diligence

A robust financial model provides the quantitative foundation for an investor conversation. It allows founders and investors to understand how the business is expected to generate revenue, manage costs, deploy capital, and progress towards profitability or future funding requirements.

Platform01 develops startup financial models covering the three-statement structure of profit and loss, balance sheet, and cash flow, together with detailed revenue and operating assumptions.

Depending on the business, our models can incorporate:

• Revenue and pricing assumptions
• Unit economics
• Customer acquisition costs
• Lifetime value
• Churn and retention
• Cohort analysis
• Headcount planning
• Operating expenditure
• Working capital
• Cash flow requirements
• Funding requirements
• Base, upside, and downside scenarios

Every model is designed to be usable beyond the initial fundraising process. Assumptions are documented, drivers are transparent, and the structure allows founders to compare actual performance against forecasts as the business develops.

For founders requiring broader business advisory services, our financial modelling can also be integrated with business planning, valuation, market analysis, and growth strategy.

Pre-Seed to Series A · Pitch Deck · Investment Narrative · Investor Outreach Strategy

Investor readiness is broader than preparing a pitch deck. Founders need a coherent investment narrative, reliable financial information, supporting documentation, and a clear process for engaging with prospective investors.

Pitch Deck Development

Platform01 develops pitch decks around the commercial fundamentals of the business, including:

• Problem and solution
• Market opportunity
• Product or service
• Business model
• Traction
• Competitive landscape
• Go-to-market strategy
• Team
• Financial projections
• Funding requirement

The objective is to create a clear and commercially credible narrative rather than simply populate a standard presentation template.

Investment Narrative and Messaging

We help founders create consistent messaging across their investor materials, including pitch decks, teasers, outreach emails, management presentations, and investor discussions.

Investor Outreach Strategy

We help founders identify investors relevant to their sector, stage, geography, and funding requirement, including venture capital funds, angel investors, family offices, and EIS/SEIS investors.

Our support can include investor mapping, outreach strategy, sequencing, preparation for investor meetings, and follow-up planning.

Due Diligence Ready · Data Room Structure · IM & CIM · Cap Table Preparation

Once an investor progresses towards due diligence, the quality and organisation of supporting information becomes increasingly important.

Platform01 helps founders prepare structured investor data rooms covering areas such as:

• Corporate and legal documents
• Financial statements
• Management accounts
• Financial models
• Cap tables
• Option pool information
• Commercial contracts
• Customer information
• Intellectual property
• Regulatory documentation
• Other investor-requested materials

We can also assist with Information Memorandums (IMs) and Confidential Information Memorandums (CIMs) where a more detailed investment document is required.

Cap Table and Funding Preparation

Founders may also require support understanding their ownership structure, option pools, dilution, and funding scenarios.

Platform01 can incorporate these considerations into the wider financial and fundraising preparation process, helping founders understand how different funding scenarios could affect ownership and future capital requirements.

Immigration Business Plans · Endorsing Body Requirements · Innovation · Viability · Scalability

The UK Innovator Founder route requires an applicant’s business or business idea to be assessed and endorsed by an approved endorsing body. Under the current Immigration Rules, the business must demonstrate that it is innovative, viable, and scalable.

The business plan is therefore an important part of the endorsement process. It needs to demonstrate the commercial rationale of the venture while addressing the relevant requirements of the Innovator Founder route.

Platform01 prepares business plans that address areas including:

• Business concept and innovation
• Market opportunity
• Competitive positioning
• Customer and go-to-market strategy
• Operational requirements
• Management capability
• Financial projections
• Growth plans
• Job creation potential
• UK and international scalability

These plans are developed around the individual business rather than adapted from generic templates.

For international founders considering the UK market, our experience across the UK, UAE, and Saudi Arabia allows us to incorporate relevant cross-border commercial considerations into the planning process.

Important: Platform01 provides business planning and advisory support; endorsement and visa decisions are made through the relevant approved bodies and UK immigration authorities. The current GOV.UK guidance maintains an official list of authorised endorsing bodies.

Business Planning and Feasibility Support

Not every founder is ready to approach investors immediately. Some businesses first need to establish whether a proposed product, market, expansion, or business model is commercially viable.

Our business plan advisory services can support founders with business planning, market research, financial projections, competitive analysis, and commercial strategy.

Where a more detailed assessment is required, Platform01 can also provide a business feasibility study UK businesses can use to evaluate a proposed project or expansion before committing significant resources.

For founders operating in London and the surrounding business ecosystem, our feasibility study consultant London support can cover market opportunity, commercial viability, financial projections, operating requirements, competitive positioning, and investment considerations.

The objective is to give founders a structured basis for deciding whether to proceed, refine the proposition, or reconsider the underlying assumptions.

P01SOaaS: Platform01 Startup-as-a-Service

Retained Advisory · Fractional CFO & Strategy Partner · Ongoing Access · Subscription Model

Startup advisory does not always end when a pitch deck or financial model is completed.

Founders often need continuing support as investor feedback changes assumptions, actual financial results replace forecasts, new opportunities emerge, and businesses prepare for subsequent funding rounds.

Platform01’s Startup-as-a-Service, or P01SOaaS, provides ongoing access to financial, strategic, and commercial advisory support through a retained subscription model.

Depending on the engagement, support can include:

• Financial model updates
• Investor readiness
• Pitch and presentation reviews
• Strategic planning
• Business planning
• Market analysis
• Valuation support
• Due diligence preparation
• Investor documentation
• Board and management preparation
• KPI monitoring
• Commercial analysis

For founders who need ongoing business advisory services without immediately building a large internal team, P01SOaaS provides access to a broader advisory capability on a flexible basis.

The model can be particularly useful during fundraising, when financial assumptions, investor materials, and strategic priorities can change quickly.

Growth Strategy and Commercial Advisory

Fundraising is only one part of building a successful business. Once capital has been raised, founders need to convert that capital into sustainable growth. This can involve market expansion, pricing, customer acquisition, partnerships, hiring, operational planning, and capital allocation.

Platform01 supports these requirements through growth strategy consulting and commercial advisory. Our work can include:

• Market and competitor analysis
• Growth opportunity assessment
• Market-entry strategy
• Customer and channel analysis
• Pricing strategy
• Go-to-market planning
• Revenue strategy
• Commercial partnerships
• Operating model development
• KPI frameworks
• Strategic planning

Our growth strategy consultancy approach combines commercial analysis with financial modelling, allowing founders to evaluate the financial implications of different strategic options.

Where appropriate, our team can also act as a business growth strategist, helping management translate strategic priorities into practical initiatives, measurable KPIs, and implementation plans.

The UK Startup Funding Landscape

Understanding the UK investment ecosystem is an important part of fundraising preparation.

London: Global VC Hub

London remains one of the UK’s major centres for venture capital, technology, financial services, and entrepreneurship. Founders in the capital have access to a broad network of venture funds, angel investors, accelerators, corporate investors, and professional service providers.

The depth of the ecosystem also means founders compete for attention from sophisticated investors. Platform01 helps London-based founders develop financial models, investment materials, business plans, and investor strategies suited to their stage and sector.

Manchester: Northern Technology Ecosystem

Manchester has developed a significant technology and innovation ecosystem spanning fintech, healthtech, deep technology, digital businesses, and professional services. Platform01 supports Manchester-based founders with fundraising preparation, financial modelling, investor materials, feasibility analysis, and growth planning.

Edinburgh & Scotland: Fintech and Deep Tech

Edinburgh and the wider Scottish ecosystem have strong links to financial services, fintech, technology, research, and university-led innovation.

Founders seeking investment in these sectors may need to communicate both the technical opportunity and the commercial pathway to investors. Platform01 provides advisory support covering financial analysis, market research, business planning, investor readiness, and transaction preparation.

Birmingham & the Midlands

Birmingham and the wider Midlands region support businesses across manufacturing, technology, consumer markets, professional services, and other sectors. Platform01 works with Midlands-based founders on business planning, commercial strategy, financial modelling, investment preparation, and growth initiatives.

EIS and SEIS Advisory

The UK’s Enterprise Investment Scheme (EIS) and Seed Enterprise Investment Scheme (SEIS) can be important considerations for eligible early-stage companies seeking investment.

For founders considering angel or institutional funding, understanding the relevant eligibility requirements and structuring considerations can form part of broader fundraising preparation.

Platform01 incorporates EIS/SEIS considerations into relevant investor-readiness and fundraising engagements, alongside financial modelling, investor materials, business planning, and capital strategy.

Where specialist legal or tax advice is required, founders should obtain advice from appropriately qualified professionals.

The Platform01 Standard

Platform01 Consulting Group works with founders and businesses that require more than generic, template-driven support. Our advisory combines financial analysis, commercial thinking, strategic planning, and practical execution support.

We work across individual projects and ongoing advisory relationships, depending on the needs and stage of the business. Our work is supported by experience across corporate finance, strategy, investment analysis, M&A, business planning, financial modelling, and commercial advisory.

Practitioner Perspective: BII and Molten Ventures Alumni

One of Platform01’s distinguishing characteristics is the investment experience within its wider team.

Our professionals have held roles at institutions including British International Investment (BII) and Molten Ventures, providing experience across investment analysis, portfolio management, valuations, and due diligence.

That perspective influences how we approach startup advisory. When we review a pitch deck, we consider whether the investment proposition is clear and supported by evidence. When we build a financial model, we focus on whether the assumptions can be understood and defended. When preparing for due diligence, we consider the information investors may need to assess the business.

The objective is not to replicate an investor’s decision. It is to help founders understand the commercial and financial questions that may arise during an investment process and prepare appropriately.

Cross-Border Startup Advisory

Many founders building businesses in the UK also have international ambitions. A UK startup may be raising from international investors, entering the GCC, establishing operations in the UAE, or exploring Saudi Arabia as a growth market.

Platform01’s UK, UAE, and Saudi Arabia experience allows us to consider these cross-border requirements as part of broader strategic and commercial planning. This can include:

• UK market entry
• GCC expansion
• International investor preparation
• Cross-border financial modelling

Frequently Asked Questions

What does Platform01’s startup advisory include for UK founders?

Platform01 provides financial modelling, investor readiness support, pitch deck development, investor documentation, data room preparation, business planning, feasibility analysis, growth strategy, and P01SOaaS retained advisory. Services can be engaged individually or combined into an integrated advisory programme based on the founder’s stage and objectives.

How does a financial model differ from a business plan?

A business plan explains the business in narrative form, covering areas such as the proposition, market, operations, strategy, and growth plan. A financial model translates those assumptions into quantitative projections covering revenue, costs, cash flow, funding requirements, and other financial metrics. Both can be important when preparing for investment.

Can Platform01 prepare a business plan for the UK Innovator Founder Visa?

Yes. Platform01 prepares business plans addressing the commercial requirements of the Innovator Founder route, including innovation, viability, and scalability. The business must ultimately be endorsed by an approved endorsing body, and endorsement and visa decisions are made by the relevant authorities.

What is P01SOaaS?

P01SOaaS, or Platform01 Startup-as-a-Service, is a retained advisory model providing ongoing access to financial, strategic, commercial, and investor-readiness support. Depending on the engagement, this can include financial model updates, pitch reviews, investor preparation, strategic planning, documentation, and ongoing business advisory.

What stages does Platform01 support?

Platform01 supports founders from pre-seed through seed and Series A/B, as well as businesses at later growth stages. The scope can range from developing the first financial model or business plan to preparing institutional investor materials, supporting due diligence, and developing growth strategies.

How does the Molten Ventures and BII experience influence Platform01’s approach?

Experience on the investor side provides exposure to investment analysis, portfolio reviews, valuation, and due diligence. Platform01 applies that perspective when helping founders prepare their financial models, investor materials, business plans, and responses to investor questions.

How much does startup advisory cost?

Platform01 works on both project and retained advisory bases. Project fees depend on the scope, complexity, and timeline of the engagement, while P01SOaaS is structured as a monthly advisory subscription based on the level of support required. A tailored scope and proposal can be provided following an initial discussion.
