Everyone celebrates the press release. The Series A LinkedIn post. The TechCrunch headline. The champagne photo on Instagram.
I read those and think: I hope you know what you just signed up for.
Because the math is brutal.
Here's the picture from the best available data. Harvard Business School research by Shikhar Ghosh on 2,000+ VC-backed companies, plus data from Carta's Founder Ownership Report and CB Insights.
The Solo Founder Math
Your odds as a solo founder who raised VC (pre-tax payout from exit):
$0: 75%
Up to $1M: 12%
$1M to $10M: 8%
$10M to $50M: 4%
$50M+: 1%
Translation:
13% chance you ever clear $1M from a VC-backed exit.
5% chance you clear $10M.
1% chance you hit the headline outcome people associate with "startup success."
Now here's the part most founders never run the numbers on.
The Co-Founder Tax
Per Carta's 2026 data, about 83% of VC-backed US startups have more than one founder. Two-founder teams are the most common (~36%), then three (~25%), then four (~12%), then five+ (~6%). Only about 17% of VC-backed startups are solo.
Same odds of an exit. Same exit outcomes. Just a smaller slice of the pie.
Two Founders
$0: 75%
Up to $1M: 14%
$1M to $10M: 7%
$10M to $50M: 3%
$50M+: 1%
Three Founders
$0: 75%
Up to $1M: 16%
$1M to $10M: 7%
$10M to $50M: 2%
$50M+: <1%
Compare the rows across all three founder counts. The "$0" outcome stays at 75% no matter the team size, because failure is failure. But as you add co-founders, more people get pushed into the "Up to $1M" bucket (12% then 14% then 16%) and fewer make it into the meaningful payout tiers.
Your odds of clearing $10M drop from 5% as a solo, to about 3% with two founders, to about 2% with three.
To be clear: I'm not telling you to raise or not to raise. Some of the biggest wealth creation events in history came from VC-backed companies. I'm just saying, go in with your eyes open. Most founders don't.
Why The Math Looks Like This
VCs aren't looking for good businesses. They're looking for moonshots. I broke down the fund math here: Why 10X Isn't Enough for VCs.
Think of your startup as a rocket. The VC is fueling the launch from Earth. The North Star, the only acceptable outcome, is hitting the moon. That's the billion-dollar exit that makes the fund work.
But here's what every astronaut knows. If you miss the moon, you don't drift back to Earth. You don't have enough fuel to land safely. You die in space.
That's the game VCs have structured. Because of power laws, they need moonshots. Singles and doubles ruin the fund math. So they push you to swing for the fences. Hit the moon, or die trying.
About 1% of the time, the founder hits the moon and becomes a household name.
The other 99%? You essentially blew up in space.
Just something to think about before you sign the term sheet.
