About FOSDEM

FOSDEM 2027 (Free and Open Source Developers’ European Meeting) is a premier annual event dedicated to open-source software development, collaboration, and innovation. The conference brings together thousands of developers, contributors, system administrators, and technology companies from around the world. 

FOSDEM exhibitors include software vendors, AI and cloud providers, integrators and startups, and attendees include CIOs, CTOs, technology leaders, founders and enterprise buyers. The FOSDEM 2027 Exhibitors List and FOSDEM 2027 Attendees List from VisitorsList give you business contacts from both groups.

Why FOSDEM Matters to IT & Technology Businesses

FOSDEM brings the IT & Technology market together in Brussels. FOSDEM exhibitors include software vendors, AI and cloud providers, integrators and startups, while FOSDEM attendees include CIOs, CTOs, technology leaders, founders and enterprise buyers.

That mix makes the FOSDEM 2027 Exhibitors List useful for partnership and competitor research, and the FOSDEM 2027 Attendees List useful for finding buyers before and after the show.

VisitorsList event data helps you identify the relevant companies and contacts behind FOSDEM, segmented by industry, job function and seniority.
