A new personal AI assistant called Tab came out of stealth on October 6 at a $300 million valuation, and its pitch is deliberately unfashionable: there is no app. Users text Tab on iMessage or WhatsApp the way they would message a person, and the assistant goes off and does the errand - with its own phone number, its own computer and its own wallet.
According to the company's site and founder Ammar Amdani's comments to TechCrunch, Tab can find and book a flight, move a hotel reservation, order a replacement part, or turn a PDF into a spreadsheet. Users can send photos, screenshots, PDFs and videos into the thread. Because the assistant runs its own browser environment, it can also place a phone call to a hotel, a doctor's office or a supplier, wait on hold, and report back in the same conversation.
The wallet is where Tab draws its line. Before any money moves, Tab shows what it plans to buy, the total, and who gets paid; nothing is charged until the user approves. Receipts land back in the thread, so the audit trail lives next to the conversation. Tab also says user data is never used to train AI models, and that the payment card sits in a vault the company itself cannot see. Those are the company's descriptions, not audited controls.
Tab was started earlier this year by Amdani, Brennan Erbz and Stafford Schlitt. Erbz was an early machine-learning engineer at Snap and previously founded Hashletes through Y Combinator; Amdani co-founded the venture firm Adapt Ventures. The backers include SV Angel, the San Francisco seed firm behind early Google and PayPal checks, Valar Ventures, the firm co-founded by Peter Thiel and Andrew McCormack, and American Spirit. The company did not disclose how much it raised.
Amdani's framing is generational: his grandparents' generation had a family doctor and a banker who knew them and looked out for them, and most people no longer do. Tab wants software to fill that gap - which is exactly why the hard part is not capability. An assistant that reads your messages, makes calls and spends money is only as good as the trust placed in it.
Tab is entering a field where rivals already carry much bigger numbers. Instinct raised $250 million at a $2.5 billion valuation on August 26 and then $1 billion at $10 billion from Sequoia Capital, Benchmark and Coatue on September 28 - a $7.5 billion jump in 33 days. Meta's Muse launched on September 8 with a free tier and $20 and $100 monthly plans. Poke, the closest analog, raised a $15 million seed and later $10 million more at the same $300 million post-money valuation, but has been live since September 2025.
Money keeps following the category. Gartner forecasts spending on AI agents and assistants rising from $29.2 billion in 2026 to $65.5 billion in 2027, with figures implying roughly thirteen-fold growth between 2025 and 2030. Against that backdrop, a $300 million valuation for a three-founder startup with a waitlist is no longer an outlier - it is the entry ticket.
The number to watch is not the valuation. It is how many people hand Tab a card, whether the approval gate survives contact with real spending habits, and whether Apple and Meta keep the messaging door open to a third-party assistant that wants to act, not just chat.
