Overview
- The company exited stealth on Wednesday, October 7, 2026, announcing a reported $300 million valuation and naming investors including SV Angel, Valar Ventures, and American Spirit.
- Tab is a San Francisco startup founded by Brennan Erbz, Stafford Schlitt, and Ammar Amdani that lets users text an AI assistant to book travel, place orders, make calls, and handle other chores.
- The product runs in its own computing environment, accepts text, photos, PDFs, videos, and voice calls, and the company says it preserves conversation context across tasks.
- Tab promotes privacy protections by saying user data will not be used to train its models, payment cards are stored in a vault the company does not access, and irreversible actions require explicit user approval, but reporters note these claims are company-reported and not independently verified.
- The service is currently behind a waitlist with no disclosed user counts or revenue, and the outsized early-stage valuation highlights strong investor appetite for assistants that execute tasks rather than only chat, raising questions about adoption, regulation, and real-world safety.
