Cofoundista
Cofoundista is a web-based platform for people seeking or offering a co-founder role at an early-stage venture. Founders create structured venture and role profiles that describe the skills needed, expected commitment and equity; prospective co-founders list their experience, skills, role preferences and availability, then browse open opportunities. Members can signal interest, and Cofoundista shares contact details after both sides agree to connect. The platform also supports incubators, accelerators, universities and venture-building programs that invite cohorts and connect them with a shared pool of candidates. Cofoundista provides founder resources including an equity-split calculator. Its matching workflow helps early teams identify potential co-founders and discuss fit before forming a company. The service is accessible through a web application, and its interface is available in English and German.

Y Combinator Co-Founder Matching
Y Combinator's Co‑Founder Matching platform is a free online service designed to help aspiring entrepreneurs find compatible co-founders.

It's suitable for individuals at various stages, whether they're in the early exploration phase or ready to launch a startup, and accommodates those with or without a specific idea in mind. It operates without any commitments, equity requirements, or obligations. Users create a profile detailing their backgrounds and preferences, after which YC's matching engine suggests potential co-founders who align with their criteria. If mutual interest is established, users can connect and initiate conversations. It boasts a vast network, having facilitated over 100,000 matches, with active profiles in major cities worldwide.
