01
Choosing on chemistry alone
A strong first conversation can hide differences in pace, communication, and expectations under pressure.
For first-time founders
Test your first cofounder partnership before you commit.
You have someone in mind. Before you split equity or leave your job, compare how you work, try a small project together, and write down the decisions you still need to make.

Before you commit
Four assumptions that become expensive later.
The cost is rarely one disagreement. It is discovering too late that each founder was operating from a different deal.
02
Delaying role clarity
Undefined ownership often becomes harder to resolve once customers, money, and deadlines arrive.
03
Agreeing equity before contribution evidence
An equity split is easier to discuss when each founder has made their expected commitment and responsibilities explicit.
04
Avoiding departure scenarios
A practical conversation about changes in commitment can protect both people if the partnership evolves.
What CofounderFit is
A structured conversation, not a verdict.
CofounderFit helps a specific pair discuss working preferences, decision habits, risk, and values. It is not a cofounder marketplace, consultancy, or prediction of success. Each founder creates a free individual profile; the shared Alignment Session is a separate paid step.
A shared process
From separate profiles to explicit decisions.
Each founder answers independently. The relationship only becomes visible when both people choose to compare and discuss it.
- 01
Answer separately
Each founder completes the 62-question assessment, then writes down their time commitment, financial constraints, and reasons for building this company.
- 02
Compare one specific pair
Invite the person you are considering. Decide together whether to use the paid Alignment Session, then discuss the strongest differences with examples from past work.
- 03
Run a two-week trial
Choose one customer or product problem. Name an owner, agree a deliverable, and observe how you handle a missed deadline or a disagreement.
- 04
Write a decision brief
Record role owners, decisions that need both founders, equity assumptions, and departure questions. Agree a review date and get professional advice on legal and financial terms.
When it helps
Use it before the partnership becomes expensive to change.
Moment 01
Before choosing between potential cofounders
Use a consistent conversation structure alongside references, working sessions, and your own judgment.
Moment 02
Before discussing a first equity split
Surface assumptions about contribution, time commitment, and decision rights before they become implicit.
Moment 03
Before joining an accelerator or studio
Start a partnership with language you can carry into onboarding, mentoring, and operating conversations.
Questions
Before you start
Can CofounderFit choose a cofounder for me?
No. CofounderFit is a conversation aid, not a verdict. Use it alongside time working together, references, shared goals, and your own judgment.
When should first-time founders use CofounderFit?
Use it when you have a specific potential cofounder, before equity, incorporation, or full-time work becomes difficult to change. The free checklist helps you prepare; a trial project gives you behavior to discuss alongside your profiles.
What should we do after reviewing the report?
Choose two differences to discuss, assign one owner to each important outcome, and test that split on a two-week project. Write down equity, vesting, and departure questions for a qualified adviser. Do not turn a compatibility score into an equity percentage.
