BuildForever is a consumer software company building products that feel personal, magical, and deeply human. Its first product, Extra (extra.email), is a free AI email app for iPhone, Mac, and Gmail that automatically organizes the inbox into smart categories, summarizes what matters in a daily digest, cleans up subscriptions and unwanted senders, answers natural-language questions about your mail, and drafts replies in your own tone. Founded and led by CEO Naveen Gavini (formerly SVP/CPO at Pinterest), BuildForever is backed by Abstract Ventures, Felicis, and DST Global, with angel investors including Ben Silbermann, Guillermo Rauch, and Paul Buchheit. The company does not currently publish a public developer API; this profile captures its consumer product surface and identity.
