Instinct raises $1 billion Series C at $10 billion valuation

Crunchbase's weekly list of the largest U.S. startup funding rounds had a clear theme: almost every deal in the Top 10 was AI-related, and the biggest of them was Instinct's $1 billion Series C. The San Francisco company, only a year old, builds a personal AI assistant for everyday tasks, and its round was backed by Sequoia Capital, Benchmark and Coatue at a $10 billion valuation. That combination — a young company, a large round, and a ten-figure valuation — is the defining feature of the week rather than an outlier.

The list illustrates how broadly the AI label now stretches across U.S. startup financing. Alongside Instinct, the rankings include EliseAI for the home rental sector, Armadin for cybersecurity, GMI Cloud and CScale for AI infrastructure, General Intuition for foundational AI models, and SiMa.ai for physical AI.

For readers watching the private markets, the coming months will test whether these valuations hold as the companies mature. Whether Instinct can turn a $1 billion raise into a widely used assistant is the open question that the $10 billion valuation now hinges on, and the same logic applies to the other large AI rounds on the list.
