How to test working with a cofounder before committing
Written by CofoundAlly · Updated
The short answer
Agree on a short trial project, usually one to four weeks, with a real deliverable, a deadline and a scheduled review. Choose work that matters to the business, such as customer interviews, a prototype or a sales pilot. Afterwards, review delivery, communication and decision making honestly before discussing equity and long-term roles.
Why a trial beats more meetings
Conversations show how someone presents themselves. Shared work shows how they behave under a deadline, how they handle disagreement and whether they finish what they start. A small project gives both of you that evidence without a long-term commitment.
Designing a useful trial
Pick one outcome you both care about and can finish in the time available. Write down who does what, how you will communicate, what done looks like and when you will review it. Agree up front who owns anything produced during the trial, especially code, designs and customer data.
Keep the trial realistic. Working on an actual customer problem reveals far more than a hypothetical exercise.
Running the review
At the review, each person answers the same questions: did we deliver what we agreed, how did we handle problems, did we communicate well, and do we want to keep going? If the answer is yes, move on to roles, equity, vesting and a founder agreement. If not, part ways on good terms and with clear ownership of what was made.
Trial partnership checklist
- Choose a real business outcome you can finish in one to four weeks.
- Write down responsibilities, communication habits and a deadline.
- Agree who owns the work produced during the trial.
- Hold a mid-point check-in and a final review.
- Decide together whether to continue, then formalize roles and equity.
Frequently asked questions
How long should a cofounder trial last?
Long enough to complete a meaningful task, usually one to four weeks. Longer trials can drift without clear milestones.
Who owns the work from a trial project?
Agree this in writing before you start. A common approach is that work transfers to the company if you continue and stays with whoever created it if you do not, but get legal advice for anything valuable.
What should a trial project be?
Real work that moves the startup forward: customer discovery interviews, a prototype, a landing page test, a sales pilot or a fundraising plan.
