Bet on the Founders, Not the Idea
At the seed stage the idea will change, so fund the people who will make something work no matter what.

Because the earliest-stage idea is 'as early as it gets' and almost always shifts, the highest-signal thing to evaluate is the founders themselves. Livingston's rule: it is worth backing exceptional founders even when you actively dislike their current idea, because scrappy, earnest, domain-fluent people find their way to something that works.
Origin
Jessica Livingston, from Y Combinator's early batch-funding years, where several of YC's most successful investments (Airbnb, Goat) were made on the founders despite skepticism about the initial idea.
Core principles
- 01Seed-stage ideas carry little information; founder quality carries most of it.
- 02A great founder plus a bad idea can pivot; a mediocre founder plus a great idea usually can't execute.
- 03The bet you're making is 'these people will figure it out,' not 'this specific product will win.'
How to run it
- 1
Separate your read of the idea from your read of the people
Explicitly decouple the two judgments. Note that you may think the product 'might not work' while still believing the founders are worth backing. Say it out loud: 'I don't know about the idea, but they seem really great.'
Pro tip Name your idea-skepticism openly so it doesn't unconsciously drag down your founder assessment.

Look for proof they'll make something happen
Weight concrete evidence of scrappiness and resourcefulness — hand-building cereal boxes to fund the company, surviving a prior hard startup — over how sexy or polished the current idea is. These are signals they'll do whatever it takes.
Pro tip Unsexy problems fixed by someone who deeply knows how broken the industry is (Parker Conrad on HR/benefits at Zenefits) are a strong tell of a real, earnest founder.
Watch out Don't let charisma substitute for evidence of hustle — demand a story where they actually made something happen against odds.

Fund the people and expect a pivot
When founder conviction is high and idea conviction is low, still fund — and assume the idea may change. Then help them shape the product toward what users actually want.
Pro tip Track your strong gut calls over 5-10 years to confirm the founder-read was right; this calibrates future bets.
Watch out This only holds at the earliest stage. The weaker your founder signal (no track record, no prior projects), the more caution the thin data demands.
In the wild
YC disliked the air-bed idea in a deliberately strict post-crash batch, but funded the founders on energy, passion and the cereal-box hustle. Livingston: 'I don't know about the idea, maybe they'll change their idea who knows but they seem really great.'
→ A bet made purely on founders that became one of the most successful companies in YC's portfolio.
Livingston backed founders whose original group-dinner idea she was excited about but whom her partners doubted; she prized the founders' proven scrappiness from a prior company.
→ The original idea failed; the founders pivoted to Goat and succeeded — vindicating the founder-first bet.
Common mistakes
Falling in love with the idea instead
Getting excited enough about an idea to fund it while ignoring weak founders inverts the correct priority and is exactly what the social-radar check guards against.
Over-applying the rule beyond seed
'Fund the founder, ignore the idea' is a seed-stage heuristic driven by data scarcity; at later stages ignoring the business fundamentals is reckless.
Is it for you?
Best for
Pre-seed/seed investors and accelerators deciding on companies that are little more than a team and an idea.
Not ideal for
Growth-stage investing, or any decision where the product already has meaningful traction data to judge.
From the transcript
“I'm totally convinced what they're working on might not work but I feel like it's so worth the bet based on these founders”
“I don't know about the idea maybe they'll change their idea who knows but they seem really great”
“they pivoted and made Goat succeed and it's doing really really well”
