Do you need a co-founder?
A co-founder is a partner who shares ownership of the company and the risk of building it. Most investors prefer to back teams, because the work is too much for one person and a second founder covers skills the first one lacks.
You probably need a co-founder if a core part of the business, like building the product or selling it, is something you can't do yourself and can't yet afford to hire for. If you need a specific task done, a freelancer or an early employee with equity may be a better fit.
What to look for in a co-founder
Complementary skills
A technical founder often pairs with someone strong in sales, marketing or operations.
Shared commitment
Agree on full-time vs part-time, how long you'll try before stopping, and how much risk each of you can carry.
Aligned goals
One of you wanting a lifestyle business and the other wanting a venture-scale exit is a common source of break-ups.
Working style
How you make decisions, handle disagreement and communicate under pressure.

How to test the fit before you commit
- 1
Work on a small project together
Spend a few weeks on something real, like customer interviews or a prototype, before talking about equity.
- 2
Have the hard conversations early
Talk about roles, titles, money, time commitment and what happens if one of you leaves.
- 3
Agree on equity with vesting
Standard vesting, often four years with a one-year cliff, protects both of you if things don't work out.
- 4
Put it in writing
A founders' agreement covering ownership, roles and decision-making saves arguments later.

Frequently asked questions
How much equity should a co-founder get?
There's no fixed rule. Many founding teams split equally or close to it when both join early and full-time. Unequal splits are common when one founder has worked on the company much longer or brings capital. Use vesting either way.
Can I find a technical co-founder if I'm not technical?
Yes. Show evidence that the business works, like customer interviews or pre-sales, and be clear about what you bring. Filter by skills on Startupply to find developers who are looking for a business partner.
