Investor Exposes Startup Metric Inflation, Passes on Founders Who Pad Numbers

In an October 15 tweet thread, an investor systematically exposed common number-inflation tactics founders use in recent due diligence, sharing cases where he passed on deals outright, sparking discussion about fundraising integrity.

Confirmed

• The first category the author lists is inflated customer counts: a founder's claimed "20 customers" might actually be 20 people in conversation, 20 free beta signups, or 20 companies still in the pipeline. He insists there is only one definition of a customer—someone who has actually paid; the rest are "at best vibes, at worst lies."
• Big-name investor participation can also be packaging: a founder claimed a well-known investor was in the round, but when contacted, that investor had only said "sounds interesting" once and never wired money.
• In one specific case, a founder's deck customer count didn't match the website—the website figure was about 10x higher. When pressed, the founder explained, "I thought I had to inflate the numbers to attract more customers; I didn't know the numbers on the website had to be real." The author's reaction: "Wow."
• In conclusion, the author concedes many cases are just loose wording, but even slightly inflated numbers make him wonder what else is inflated, so he passed on the deal. His maxim: trust starts at 100% and only goes down.
• Hustle Fund partner Elizabeth Yin, in a thread on the same topic, pointed out another common mistake: many founders linearly extrapolate run rate from launch-day customer counts, but a launch-day traffic spike doesn't equal run rate; run rate should be annualized based on the trailing 12-month average, and only paying users count as customers.

Why it matters

• For founders, these posts draw red lines for fundraising narratives: inflation anywhere—customer definitions, investor participation, website data—can make investors doubt every other number and kill the deal outright.
• For investors, the posts offer a due diligence checklist: cross-check deck and website numbers, contact so-called participating investors directly, and recalculate customer counts and run rate on a paid basis.
