The valuation has quadrupled in a month. In August, Instinct was valued at $2.5 billion in a round co-led by Index Ventures and Benchmark, SiliconANGLE reports. The service opened by invitation in August and remains in early access. Users and revenue are undisclosed.

Users reach the agent by text or phone call, and it works from its own phone number and computer. It books trips and restaurant tables, orders groceries, pays bills, cancels subscriptions and phones businesses. It can also coordinate with the agents of people its user trusts.

Instinct competes with about a dozen agent products, among them the agent versions of ChatGPT and Meta’s Muse, SiliconANGLE notes. On the same day, Shopify named Instinct as a partner for agent checkout with Shop Pay.

For brands, a well-funded agent that shops for its users is a buyer that reads product listings and prices before any person looks at them.
