Who we are
Zelph was founded by the team that built and scaled Kick Game to £60m in revenue, one of the largest resale marketplaces in Europe. We’ve lived the fragmented systems, the manual processes, the stack that can’t keep up with growth.
The platform we built for Mamedica took the clinic to #8 in The Sunday Times 100 fastest-growing private companies, 2026. The first medical cannabis company in the ranking’s 29-year history.
