Arena
Arena is a San Francisco-based audience engagement platform that turns publishers' and brands' own websites into social-network-like communities. Through live blogs, group chats, comments, AI-powered content feeds and audience analytics, Arena helps over 20,000 organizations - including Fox Sports - keep readers on-site, collect first-party data and monetize attention they used to give away to social platforms.
Paulo Martins
Paulo Martins is the Brazilian-born founder and CEO of Arena (arena.im), a San Francisco-based AI-powered community engagement platform that lets brands embed live chat, live blogs, and audience interaction tools directly on their own websites with a single line of code. After stints at NASA, Ubisoft, and Hulu — where he helped grow the streaming company from 100K to 7 million paying subscribers — Martins founded Arena in 2017 with a clear thesis: businesses should own their audience, not rent it from social platforms. By 2022, Arena had grown to 25,000 customers across 150 countries and closed a $13.6M Series A led by CRV, with backing from heavyweights like David Sacks, Des Traynor, and Olivier Pomel.
