Due diligence tests whether the financial, legal and commercial story a company tells actually holds up under a second read. The purpose is not to find new information as much as to confirm the numbers are consistent, the cap table is clean, and no one is the single point of failure the model depends on.
What due diligence actually checks
Financial diligence confirms the numbers: revenue quality, margin integrity, a quality-of-earnings review if the deal is large enough to warrant one, and whether the reported figures match what the underlying systems show. Legal diligence checks contracts, IP ownership and the cap table. Commercial diligence tests the growth story: customer concentration, churn, and whether the pipeline the deck describes is real. An investor's questions about the financial statements are rarely about the headline number. They are about whether the number would survive someone else recalculating it.
Why it is not a once-in-a-while event
At a genuinely fast-growing business, diligence is not a discrete milestone you prepare for once. Alexey Mitko, who built finance from scratch at Eucalyptus before it sold for $1.6 billion, told me on The CFO Track that the business raised almost every six months in its early days, so diligence was “a thing you would do almost constantly.” When an investor asks for a metric mid-round and no one owns the model, you are reconstructing it under pressure, and that is precisely the job a finance hire exists to have already done.
The technical detail matters too, and it shows up in how candidates get found for these roles. Recruiters search for specific technical terms, “working capital facility,” “SPA vetting,” “financial due diligence,” not generic terms like “leadership” or “communication.” A profile filled with specific, technical language is what actually gets a genuinely diligence- capable finance leader found.[1]
What stalls a diligence process
Diligence does not usually surface brand-new information. It tests whether the story someone told holds up under a second read. A data room with numbers that shift depending on who is asked, a cap table with side letters nobody remembers agreeing to, or a model no one but the founder can explain are the three things that reliably slow a deal down or kill it outright. None of them are fixable in the two weeks between a term sheet and a diligence request; they have to be true before the process starts.
A clean cap tableis one of the fastest wins before diligence starts.
A model only one person can explain is also how investors read key person risk.
Common questions
What do investors actually look for in due diligence?
Whether the financial, legal and commercial story a company tells holds up under a second read. That means revenue and margin quality, whether the reported figures match the underlying systems, a clean cap table, current contracts, and a growth story that survives scrutiny on customer concentration and churn, not just the headline numbers in the deck.
Is due diligence only for a sale or acquisition?
No. It happens in some form in every capital raise, not just a sale. At a fast-growing business raising every six to twelve months, diligence is closer to a constant background process than a single discrete event you prepare for once and move past.
What most commonly stalls a due diligence process?
Numbers that shift depending on who is asked, a cap table with side agreements nobody remembers, and a financial model only the founder can explain. Fixing any of these in the short window between a term sheet and a diligence request is rarely possible; they need to already be true well before the process starts.
How do you get a finance function diligence-ready?
Start well before a live process. A documented, consistent monthly close, a cap table everyone agrees on including options, current contracts, and a model someone other than the founder can walk an investor through are the core of it. That readiness is usually the first job of a first finance hire, not an afterthought.
