Official Page

MassChallenge is a startup accelerator network that runs a four-month early-stage programme in the United Kingdom. The 2026 edition was its fourth UK cohort and welcomed 80 early-stage startups.

Teams work from office space in the Royal Docks in East London, join online programming through the four months, and attend in-person events in London and Lausanne. MassChallenge takes no equity in return.

The UK cohort concentrates on two areas — AI, autonomy and cybersecurity, and foodtech and agritech — while still accepting startups from other sectors that create positive impact. It runs alongside the MassChallenge Switzerland cohort and competes for the same prize pool, with an extra award reserved for the strongest UK team.
