TechCrunch reported that US personal AI assistant startup Tab emerged from stealth on October 6 at a $300 million valuation, with SV Angel, Valar Ventures and American Spirit among its investors; the company did not disclose the actual amount raised, nor its user numbers, revenue or paid usage. Tab is operated by Terrasoft, a Y Combinator Winter 2020 batch company, and users can send instructions via iMessage or WhatsApp to order food, plan trips, buy gifts, make calls or pay bills; it has its own phone number, computer and wallet, and can connect accounts including Gmail, Google Calendar, Slack, GitHub, Linear and Notion, though it remains in closed beta. In a 15-task test by the independent Assistant Benchmark site, Tab received 97 messages over two days with a median reply time of 12 seconds, scoring 5.9 overall and ranking 21st: it earned 10 for a phone task and 9 for permissions and privacy, but only 3 for restaurant booking by web and phone, 5 for a travel task and 1 for a purchase task, where card payments failed repeatedly. The leaderboard's top three were Meta Muse at 9.3, Instinct at 8.5 and OpenAI Dots at 8.4.
