This is a weekly feature that runs down the week’s top 10 announced funding rounds in the U.S. Check out last week’s biggest funding deal roundup here. This week, most of the largest U.S. startup funding rounds centered around the sector one would suspect: artificial intelligence. This was true for the week’s largest venture financing, a $1.5 billion Series F for AI inference technology provider Baseten, as well as a majority of rounds in the Top 10. Beyond that, the next-biggest area for startup funding was biotech. 1. Baseten, $1.5B, AI inference technology: Baseten, a provider of systems software to run AI applications workloads, raised $1.5 billion in Series F funding, its fourth fundraise in 18 months. Altimeter Capital, Conviction Partners, Spark Capital, Sands Capital and Wellington Management co-led the round, which set a $13 billion valuation for the San Francisco-based company. 2. AppsFlyer, $1B, digital marketing: AppsFlyer, a San Francisco-based provider of data analytics with digital marketing as a core use case, reportedly secured more than $1 billion in a Series E funding round at a post-money valuation of $2.7 billion. Backers reportedly include Unity, Meta, Moloco and Google. 3. Groq, $650M, AI inference technology: San Francisco-based Groq closed on $650 million in new funding led by Infinitum and Disruptive that it says will be used to scale its AI inference cloud technology and infrastructure. The investment comes just over six months after an acquihire-type transaction in which Nvidia hired away its founder and key team members and licensed its technology.
