Personal-assistant startup Instinct has raised a $1 billion Series C from investors including Sequoia Capital, Benchmark, and Coatue, valuing the company at $10 billion. The financing comes just a month after a round that valued the invite-only service at $2.5 billion.
Instinct communicates through text messages and uses its own phone number and computer to book travel and restaurants, make purchases, pay bills, cancel subscriptions, and conduct research. A newer concierge feature can place calls for appointments, while a trusted-person network lets one user’s agent coordinate plans with another person’s agent.
The startup launched its service in August 2026 and has not disclosed user counts or growth metrics. Its access to personal information has also drawn scrutiny; the company revised an early privacy policy after concerns about how much data it sought. Competition is rising from Meta’s Muse assistant, which can perform similar tasks and integrate with Meta’s social products, while Instinct does not yet offer a mobile app. The valuation reflects investor enthusiasm more clearly than demonstrated operating results, and adoption will depend on whether users trust an agent with the payment details, communications, and account access needed to act on their behalf.
