If a diligence team would poke a hole in your deck, better it's you who finds it first.
I've sat on the other side of this exact process, evaluating funding proposals for an investment firm, reading the commercial and go-to-market story behind a raise and testing whether the numbers held up. This audit is that same read, run for the founder instead, before the deck ever reaches an investor's hands.
Most founders don't inflate their numbers on purpose. A study out of the University of Cologne, covering 176 German startups, found that founders' own revenue projections came in on average 388% higher than what the business actually went on to deliver, not because people lie, but because nobody around them is incentivised to stress-test the model before it goes out the door.
This audit is that stress test: the same hands-on scrutiny a PE or VC diligence team would apply, run on your own deck, early enough that you can actually do something about what it finds.
