About
Hopin was founded in 2019 by Johnny Boufarhat as a virtual event platform designed to replicate the spontaneous networking and multi-session structure of in-person conferences in an online format. The platform launched just before the COVID-19 pandemic forced the global events industry to shift entirely to digital, creating an extraordinary product-market fit moment that drove Hopin from near-zero to a $7.8 billion valuation in under two years — one of the fastest valuation escalations in European startup history. Hopin's core technology offered a multi-stage event architecture with simultaneous sessions, expo halls, and AI-powered attendee matching that no incumbent platform could replicate at launch.\n\nHopin's platform supported virtual and hybrid events ranging from small team off-sites to conferences with tens of thousands of attendees, with features including breakout networking rooms, sponsor booths, live streaming, and analytics dashboards for organizers. The company aggressively expanded through acquisitions, purchasing StreamYard, Streamable, and several other media and production tools to build a broader creator and events infrastructure stack. At its peak, Hopin served thousands of event organizers across enterprise, media, and nonprofit sectors.\n\nHopin's trajectory became one of the defining cautionary narratives of pandemic-era startup valuations. As in-person events returned, demand for virtual-first platforms collapsed. RingCentral acquired Hopin's event platform assets for $15 million in August 2023 — a 99.8% markdown from peak valuation — and rebranded it RingCentral Events. In April 2024, Bending Spoons acquired additional Hopin assets. The company raised over $1 billion in venture funding during its growth phase, making it one of the most studied examples of COVID-era valuation inflation and its aftermath.
