Tab Personal AI Assistant Emerges From Stealth at $300M Valuation, Enters Competitive Agent Market

Tab, a personal AI assistant that executes tasks autonomously via text, has emerged from stealth on Tuesday with a $300 million valuation. The startup, founded earlier this year by Brennan Erbz, Stafford Schlitt, and Ammar Amdani, joins a rapidly heating market for consumer AI agents that includes established competitors like Instinct (valued at $10 billion following this week's Series C) and Meta's Muse, which became the most-downloaded free app on the US App Store within two weeks of its September launch.
