About Semble

Semble (formerly Heydoc) is a London cloud clinical and practice-management platform for private outpatient providers — coordinating the patient journey with EHR, booking, billing, telehealth and e-prescribing, plus 1,200+ integrations via Semble Connect. Founded by Christoph Lippuner and Mikael Landau, press around the raise cited more than 10 million patients served and ~1,700 customers including Nuffield Health, Welbeck and London Doctors Clinic, with growing traction in France. In June 2026 Semble raised a £30 million (€34.7 million) Series C led by Revaia, with new investor Partech and returning Mercia Ventures and Octopus Ventures participating. Capital expands into larger healthcare groups, deepens AI care-orchestration and cements the France position. Sources: Semble 4 Jun 2026; EU-Startups; Mercia.
