Guides › Starting a business
Two people who get on well start something together and settle the pleasant questions. The unpleasant ones — what happens if one wants out, who decides when you disagree — get deferred, and those are the ones that end businesses.
Short answer: Settle decision rights, exit terms, accountability for contributions, and ownership changes before starting the business. These are the issues that end partnerships when left unaddressed, and they are easiest to resolve at the outset when nothing is at stake. Equal ownership often creates deadlock without a tiebreak mechanism, so base splits on ongoing contribution with vesting instead.
Who decides when you cannot agree. What each person is actually accountable for. What happens if one wants to leave, or stops contributing, or needs money out. How ownership changes if contributions diverge.
These conversations are uncomfortable precisely when they are easiest to have — at the start, when there is nothing at stake and goodwill is high. Every month of delay raises the cost.
Fifty-fifty feels fair and creates deadlock, with no mechanism to resolve a genuine disagreement. It also assumes contributions stay equal, which they rarely do over years.
Vesting over time, and a defined tiebreak, protect the partnership rather than threatening it. They are the mechanisms that let a disagreement be resolved without ending the business.
This question routes to Startup Genius — one of 29 engagements the platform runs. It does not produce advice in general; it produces this analysis for your business:
✓ Sizes who could realistically buy this — not the size of the industry
✓ Estimates what a customer costs to acquire and what they are worth to you
✓ Tests whether the gap between those two survives contact with reality
✓ Models the cash you need and when break-even actually arrives
✓ Names the assumptions the whole idea rests on, ranked by damage if wrong
✓ Gives the cheapest test that would prove the riskiest one false
You watch the analysis get built before you pay anything. Read a complete report here if you would rather see the depth first.
It can work well, and it requires being more formal rather than less. The instinct to keep things casual because you trust each other is exactly what leaves the friendship exposed when something goes wrong.
Based on contribution over time rather than on the initial idea, and vesting so that ownership follows continued involvement. Splitting on day one for work not yet done is the arrangement most commonly regretted.
Decision rights, what each person is responsible for, how someone exits, how ownership is valued, and what happens if a partner stops contributing. This is one of the few areas where paying a professional early is unambiguously worth it.
