This week we continue our series on the top 5 VC-funded deals in AI.
Venture capital activity cooled off this week, where we saw just three fundraising announcements come in above the $100 million threshold.
The biggest announcement, per FinSMEs, came from San Jose, Calif.-based Ayar Labs, which raised $500 million in a Series E at a $3.75 billion valuation. Ayar Labs, which creates high-speed networking technology for AI infrastructure, will use its new funding to "scale production and test capacity, expand global operations, including at its new Hsinchu, Taiwan, office, strengthen ecosystem partnerships, and accelerate the deployment of its CPO solution," according to the announcement. Our second announcement is from Beijing-based embodied AI firm Spirit AI, which raised $280 million in funding E to "scale the deployment of its embodied models, expand its data collection to exceed 1 million hours by 2026, and accelerate the integration of robotic agents into industrial workforces," according to its announcement. The top five also included companies in the extended reality, real estate and security spaces.
Smaller funding raises that did not quite make our top 5 this week included announcements from the computer vision, health, and finance sectors.
