Claude
Claude (Opus 4 / Sonnet 4)
Write the executive summary last — you can only summarise what you've fully thought through
Use real market data sources (Gartner, IBISWorld, Statista) rather than AI-estimated market sizes
The financial model is your most scrutinised section by investors — be conservative in Year 1
Know your assumptions — investors ask 'why 15% conversion?' more than they ask 'what's your revenue?'
Overstating TAM (Total Addressable Market) — 'our TAM is $500B' with no sub-segmentation is a red flag
Underdeveloped competitor analysis — 'we have no competitors' is never true and destroys credibility
Financial projections that go to 10x in year 2 without explaining how
Forgetting to include a clear, specific 'use of funds' breakdown
- How long should a business plan be?For investors, a pitch deck (10–15 slides) plus a financial model is often more useful than a 50-page plan. For bank loans, a formal 20–30 page plan is usually required. Match the format to the audience.
- Can AI help with financial projections?AI can build the structure and formulas, but the assumptions must come from real data — your pricing, your sales cycle, your actual costs. Projections based on made-up assumptions are worse than no projections.
- Which model writes the best business plans?Claude Opus 4 is strongest for business plans — it follows complex structural constraints, writes in a formal register, and produces more coherent multi-section documents than alternatives.
- Should I include a SWOT analysis?Yes, but make it strategic. A SWOT with generic points ('opportunity: large market') adds no value. Each point should be specific enough to inform a decision.
