What investors actually check before they wire
Diligence is not an insult and it is not a formality. It is the point where every number in the deck either has evidence behind it or does not. Founders who lose rounds at this stage rarely lose them for having small numbers.

That the company legally exists, in the form you said
The first check is the dullest. Is there a registered company, is it registered where you said, are the directors the people in the room, and is the share structure what the cap table claims.
In Nigeria this is a CAC registration and a status report. It sounds trivial until a round stalls because the entity taking the money was registered as a business name rather than a limited company, or because a co-founder who left two years ago is still on file as a director.
Check your own filings before an investor does. Fixing a registration takes weeks and it is a terrible thing to discover during a raise.
That the revenue is real revenue
Bank statements, not a spreadsheet. An investor wants to see money arriving from customers who are not related to the founders, on a schedule that matches the story.
Three things reliably cause trouble here. Revenue that includes grant money or the founders' own capital. Revenue booked when a contract was signed rather than when cash arrived. And a single large payment annualised into a headline figure.
None of these are fatal if you disclose them yourself. All of them are close to fatal if the investor finds them.
That the customers exist and would say so
Expect calls to your customers. Not many, usually three to five, and usually ones the investor picks rather than ones you offer.
What they ask is simple: do you use this, what did it replace, what would you do if it disappeared tomorrow. A customer who says they would be mildly inconvenienced has just repriced the company.
This is also where concentration surfaces. If one customer is a large share of revenue, say so first. Volunteering fragility reads as command of the business. Having it discovered reads as either not knowing or not telling.
That the people are who they say they are
Founder identity, prior roles, and whether the story of the last five years holds together. Most of this is a search and two reference calls.
Overstated titles are the usual casualty. A founder who was on a team at a bank and described themselves as having run the division has not committed fraud, but they have told an investor that their claims need checking, and that suspicion then applies to every number in the deck.
How to be ready before you start
The last item is the one that separates a smooth raise from a slow one. Every early company has something awkward in the file. The investor is not looking for a company with nothing awkward. They are looking for a founder who already knew.
- Certificate of incorporation and a current status report on the company.
- A cap table that reconciles with your filings, including anything convertible.
- Twelve months of bank statements for the company account.
- Your three to five largest customer contracts or written agreements.
- Employment or contractor agreements for anyone material, including co-founders.
- Any licence the business needs to operate legally in its sector.
- A short written note on any of the above that is messy, with what you are doing about it.
Why GTM separates claimed from verified
On this platform every founder statement is marked as founder-stated until somebody checks it. Verified means a specific check was performed, and the method is shown next to the result.
Unverified is not the same as failed, and the interface never conflates the two. Most claims sit unverified simply because nobody has looked yet, and implying otherwise would be its own kind of dishonesty.
