Write the invitation before searching
Explain the problem, what you have already learned, what you personally bring, the responsibility you want someone else to own and the time available during term. A role label alone is rarely enough. “Need a CTO for a billion-dollar idea” asks for trust before offering evidence.
“I have spoken with six student society organisers about event sign-ups. I can handle interviews and operations for four hours a week. I am looking for someone who enjoys simple web prototypes to test a sign-up flow with one society over the next two weeks.”
Meet potential collaborators in relevant places
Look where people already make things: course projects, student entrepreneurship or maker groups, hackathons, research demonstrations and community projects. Ask organisers whether it is appropriate to share a short project brief. An introduction from a classmate can help, but do not assume a friend has the same goals or capacity.
Online, describe the task and contribution in a relevant community rather than sending the same generic message to many people. Adult students can also explore Aspair's Co-founders space; current app registration is 18+ and the available member pool may be limited.
Ask about decisions and time, not just skills
Discuss a recent project each person finished, how they handled a missed deadline and what they would own in this test. Compare exam weeks, internships, location and the hours each can reliably give. Ask what happens if one person wants to stop. A complementary skill matters, but so do follow-through and respectful disagreement.
Use the co-founder fit worksheet as a conversation aid. It cannot certify compatibility; both people need to make their own judgment.
Run a short trial before making promises
Choose one output and a deadline: five user interviews with notes, a working prototype of one task or a campus event workflow. Divide responsibilities, agree on one check-in and review both the result and how decisions were made. Keep the test small enough to fit around study.
A trial is not an equity agreement. Before sharing sensitive work or discussing ownership, write down what each person created and get suitable advice where needed. The student team checklist helps you set the first project boundaries.
Send an invitation someone can answer
“Hi, I saw the scheduling tool you built for the robotics club. I am testing whether a simpler sign-up process helps our student societies. I can bring organiser interviews and access to one event. Would you be interested in a 20-minute call to discuss a two-week test? No commitment beyond that conversation.”
Personalise the message truthfully and respect a no or no reply. Explain what you would like to do together without claiming the person is already your co-founder.
