A set of pre-commitment conversations co-founders should have before starting a company together — analogous to a marriage prenup. Because a majority of startups fail from founder conflict, the prenup forces explicit alignment (or productive negotiation of misalignment) across five areas: values, vision of success, how each person handles conflict, how you decide when you disagree, and what company culture you want. It's an ongoing discussion, not a one-time checklist.
Origin
Alisa Cohn's tool for founding teams; she cites Noam Wasserman's finding that 65% of startups fail due to founder/founding-team conflict.
Core principles
- 01Co-founding is like a marriage in a business context — you're committing for a long time
- 02Aligned or adjacent values are fine; conflicting values just need an explicit conversation
- 03Undiscussed differences in vision come home to roost when it's too late to change course
- 04There are many valid ways to decide disagreements — pick one upfront
- 05Revisit these conversations regularly; people and circumstances change
How to run it
- 1
Clarify and compare core values
Each founder does a values-clarification exercise (pull ~20 from any online list, winnow to 10, then to 3-5 core). Compare them: aligned or adjacent is great; conflicting values (e.g. Excellence vs Work-Life Balance) demand a conversation about what each means and how they'll coexist.
Pro tip Redo the exercise roughly yearly — values shift, and knowing yours lets you operate with more clarity.
Watch out People acting 'strangely' are often just acting in accordance with values you never discussed — misread as character flaws.

Align on the vision of success
Ask what the company looks like when it's successful: control and independence with freedom, or a big venture-scale outcome? Surface the trade-offs each implies before it's too late to change.
Watch out If you assume you share a vision but never make it explicit, the difference surfaces years in when you're already venture-backed and it's too late to reconcile.

Explore how each of you handles conflict
A two-part question: how do you handle conflict, and — ask someone close to you — how do you actually handle it? One founder may want to raise conflict immediately; another needs to let it settle and process alone.
Pro tip The outside view corrects your self-flattering story ('I'm so neutral about conflict') with how you really behave (e.g. seething before you finally raise it).
Watch out A 'talk about it now' person paired with a 'let me process it myself' person creates conflict over the conflict if never discussed.

Decide how you'll decide when you disagree
Agree upfront on a disagreement-resolution rule: the person who cares most wins, or the person with most expertise wins, or alternate (you win this one, I win the next). All are valid — pick one.
Pro tip Disagreement is normal and healthy dynamic tension; having a practice for it makes it a good conversation rather than a sulky one.
- 5
Align on company culture
Name the culture each of you wants — 'loving family working hard together' vs 'get-it-done results-focused execution.' They can coexist, but if each founder pushes one without the other, employees end up feeling there are two different companies.
Watch out Divergent, unspoken culture pushes produce sites where employees say 'it feels like we have two different companies' depending on whose team they're on.
In the wild
Five or six years in, one co-founder said wistfully he wished they could have fewer employees and stay small enough to know everyone's name — but they were already venture-backed and the other co-founder had lofty big-company ambitions they'd never discussed.
→ It was too late to have the vision conversation; the reckoning that they were never on the same page was painful for both.
One founder texted and Slacked his co-founder on weekends; the co-founder didn't respond, which was extremely frustrating. When they finally addressed it, it was simply about wanting downtime and balance.
→ Because they never discussed it upfront, both made big assumptions and it caused avoidable conflict that a prior conversation would have prevented.
Common mistakes
Committing quickly without doing the work of getting to know each other
'Cool idea, let's just do it' skips the values, vision, and conflict conversations, so major misalignments only surface once you're deep in and hard to unwind — a leading cause of the 65% founder-conflict failure rate.
Assuming you share a vision or culture because you're friends
Founders who know each other socially (even since youth) assume alignment, but they've matured into different people with different ambitions; unstated differences in vision or culture split the company later.
Is it for you?
Best for
Prospective co-founders — especially friends — about to start a company together
Not ideal for
Solo founders, or teams already years in where the honest conversations may already be overdue rather than preventive
