AI Assistant Startup Instinct Targets $250M Round at $2.5B Valuation

Instinct, a fast‑rising U.S. startup building an AI assistant for everyday knowledge work, is in the process of raising a $250 million Series B round that would value the company at around $2.5 billion. According to reports, the deal is expected to be led by top‑tier venture capital firms Benchmark and Index Ventures, underscoring how competitive the “AI secretary” space has become. Instinct’s product connects to email, documents, calendars, and task managers to automate routine workflows for individuals and teams, and the company has been piloting enterprise deployments with larger customers. The prospective mega‑round highlights that investors still see plenty of upside in AI assistants, even as the market is increasingly crowded by offerings from OpenAI, big tech platforms, and a host of agent‑style tools. The startup will need to show that it can stand out not only on raw model quality but also on data privacy, auditability of decisions, and seamless integration into existing software stacks. As capital keeps pouring into the sector, Instinct’s raise is another sign that the next phase will be less about eye‑catching demos and more about which assistants deliver durable productivity gains and a sustainable business model.
