Companies at the summit

109 companies, taken from the team's company map and re-checked at their sources by this newsroom. Each is confirmed for Web Summit Lisbon 2026 on one of the summit's own pages (its partners, startups, speakers or sessions), unless its profile says otherwise. Being listed here is not an endorsement, and not a sign that we have met them.

Find them another way: by topic (the industry map), by country, or through the people listed under them and the events they are at. Each company's page links to its sessions, its people and the companies related to it.
