Where founders, investors, and mentors connect
A white-label platform for founder engagement, portfolio support, mentorship, deal flow, and ecosystem growth.
How Joinee creates value
Joinee helps accelerators, venture funds, and founder communities build measurable ecosystem infrastructure that supports portfolio development, founder engagement, investor relations, mentorship, strategic partnerships, and long-term network growth.
The platform brings together founders, investors, mentors, experts, corporate partners, and ecosystem stakeholders into one organization-owned digital community — under the accelerator’s or fund’s own brand and control.
Originally developed for alumni communities, Joinee has grown into a community infrastructure platform used by accelerators, universities, research organizations, professional networks, and business communities across Europe, North America, and the Middle East.
