What investors actually read
Most investors will spend fewer than five minutes on an initial business plan review. They are pattern-matching for problems worth solving, credible teams and realistic financial models. The documents that survive this cut share certain qualities that have nothing to do with beautiful design or length.
Lead with the problem
Before anything else, articulate the problem you are solving with precision. Not just that the market is big — but that a specific number of people currently have to do a specific thing in a way that costs them quantifiable time and money, and existing solutions fail because of specific, defensible reasons.
Market sizing: bottom-up beats top-down
Saying the global logistics market is enormous and you only need 1% is a red flag. Investors have seen it thousands of times. Instead, calculate from the bottom up: there are 50,000 UK businesses with this problem, each spending £2,000 per year on the current solution, giving a serviceable addressable market of £100m. That is credible.
Financial projections
Your projections will be wrong. Investors know this. What they are looking for is whether your assumptions are sensible and internally consistent. Every number needs a source. Show the model, not just the output.
The team slide
Venture investors back people as much as ideas. Show relevant experience, be honest about gaps, and explain how you plan to fill them.
