Due diligence is the process where investors verify everything you have told them during the pitch. It is more thorough than most founders think.
The four main areas
Commercial due diligence
Investors will verify that the market is what you say, that customers exist, and that unit economics actually hold up.
Technical due diligence
For tech startups they review the codebase, the architecture and the technical debt. Have a technical CTO ready to explain choices.
Legal due diligence
Shareholder agreements, IP rights, employment contracts and any disputes. Everything must be documented.
Financial due diligence
Historical numbers, forecasts and assumptions. Be honest — they will find errors.
How to prepare
Start the data room early. Have all documents available and organised. Use Foundry House's document module to structure this.
