6 Reasons Why Startups Need a Business Plan for Series a Funding
18th March 2025
Securing series A funding is a significant milestone for startups, but it’s also a challenging hurdle. In fact only 20-30% of seeded companies successfully raise a series A round. This statistic underscores the importance of one key asset…
Your series A business plan.
A well-crafted business plan is vital for startups seeking series A funding as it serves as a roadmap for growth and a tool to attract potential investors.
A comprehensive business plan can also significantly improve a startup’s chances of securing funding. While exact figures vary, startups with robust business plans are generally more likely to secure investment. For instance:
- Companies that join top-tier accelerators, which often help refine business plans, have a higher statistical chance of securing series A funding.
- Only 20-30% of companies that raise a seed round are successful in then raising a series A investment.
These statistics highlight the critical role a well-prepared business plan plays in convincing investors of a startup’s potential and readiness for series A funding.

1. Demonstrates market fit and growth potential
A robust business plan showcases your startup’s market fit and growth potential. It outlines your objectives, market potential, and competitive edge. Investors in series A funding are looking for startups that have demonstrated a clear market fit and are ready for scaling. Your business plan should articulate your unique value proposition and differentiation strategy, illustrating how your product or service solves a problem effectively.

Typically, series A valuations for UK companies range between £10 million to £30 million or more, with the median series A funding amount around £7.7 million in 2022-2023. According to recent data, series A rounds in the UK can raise between £3 million to £20 million or more, depending on the company’s market potential and growth prospects.

Series A business plan checklist
Crafting a business plan for series A funding requires precision and attention to detail. Here’s a checklist to help you ensure your business plan is series A-ready:
- Executive summary: Does it succinctly describe your business, target market, and value proposition?
- Market analysis: Have you provided data on market size, target audience, and trends?
- Competitive landscape: Does your plan identify competitors and highlight your unique advantage?
- Financial projections: Are revenue, cost, and profit margin forecasts clear and realistic?
- Use of funds: Have you detailed how the series A investment will be allocated?
- Scalability: Does the plan demonstrate your ability to grow sustainably?
- Team expertise: Have you showcased the strengths and relevant experience of your leadership team?
Demonstrate market traction
Investors expect Series A startups to provide concrete evidence of market traction rather than early-stage validation. Here’s how to showcase this effectively:
- Product–market fit: Present validated user feedback, testimonials, and engagement data that prove your solution is solving a real problem for a loyal customer base.
- Revenue growth and KPIs: Highlight consistent revenue growth, customer acquisition trends, and other key performance indicators that demonstrate momentum.
- Customer engagement metrics: Show strong retention rates, repeat purchases, customer satisfaction scores, and other engagement metrics that indicate long-term viability.
- Marketing performance: Provide verified data on customer acquisition costs (CAC), conversion rates, and channel performance, demonstrating a scalable and repeatable growth strategy.
The role of your investor pitch deck
While a business plan is a detailed document that outlines your long-term vision, an investor pitch deck is a concise presentation designed to grab investors’ attention quickly. Both are essential in the fundraising process, but they serve distinct purposes.
- Business plan: Provides comprehensive details about your startup, including market research, financial projections, and strategic goals. It is usually shared with investors after initial interest is piqued.
- Pitch deck: Acts as the visual summary and first impression. It’s used during pitch meetings to communicate key highlights, such as your market opportunity, product offering, and revenue model.
