Find builders by skills, industry, location, and availability.
Compare your startup goals, available hours, and expectations before agreeing to work together.
Use a trial partnership to agree on tasks and evaluate collaboration before making a longer commitment.
A useful introduction starts with a clear account of the work, the commitment, and what each person hopes to build.
Write down the next outcome your team needs, such as a working prototype, customer interviews, or a first sales process. Look for experience that helps deliver that outcome. Discuss examples of previous work and how responsibilities would be shared, rather than choosing on a job title alone.
Compare weekly availability, time zones, financial expectations, and the stage of the business. Ask who makes product decisions, how disagreements are handled, and what happens if someone needs to leave. Keep sensitive documents private while you establish whether the opportunity is relevant.
For a local search, compare the country and location in each profile with where you need to work. For a remote team, agree on overlapping hours, working language and a shared delivery schedule. A developer in another time zone may be a useful partner when you can review work together; a local business cofounder may help when customer conversations need local context. Judge the fit from the current profiles and a real conversation, rather than assuming the network has the same availability in every country.
Agree on a short task with a deadline and a shared review. Use the experience to discuss communication, delivery, and how feedback is handled. CofoundAlly’s trial partnership tools help structure that work before a longer commitment. An introduction or verification badge does not replace your own assessment of a potential partner.
Example brief: “I am validating appointment software for independent clinics. I handle customer interviews and operations. I am looking for a technical cofounder to build and test a booking prototype. We would agree on weekly hours, overlapping working time and a small trial task before a longer commitment.” Replace the example with your actual progress, the work you can own and the skills you need. If you already build the product, describe the customer research or sales work a business cofounder would lead.

Describe the work your startup needs: product engineering, customer research, sales, or operations. Compare experience, relevant skills and weekly availability, then discuss responsibilities before proposing a partnership.
Use the country and location filters to narrow a local search. For a remote partnership, compare time-zone overlap, working language, weekly availability and the customer market each person understands. Agree on a small shared task before committing. Availability depends on the profiles currently in the network; an introduction is not guaranteed.
Create your founder profile, describe the startup and the skills you need, then use discovery to compare potential collaborators by skills, industry, location, and availability. Start a conversation about the work and commitment before deciding to collaborate.
Use a trial partnership to agree on tasks, a deadline, and a shared review. The experience gives you practical evidence about communication, delivery, and how you make decisions together.
Member discovery and conversations require account access. The public page describes the service without exposing member profiles, private messages, or contact details.
