This week we continue our series on the top 5 VC-funded deals in AI.

This week our announcements are led by two huge deals exceeding the $100 million threshold.

The week’s top reported deal, per FinSMEs, came from San Franciso based Lambda, an AI cloud company, which raised a $480 million Series D round to continue building out its cloud infrastructure for AI developers and users. The next biggest announcement also came from the cloud space, where Together AI (mis-spelled on FinSMEs as “Togheter AI”), which also happens to be based in San Francisco, brought in a $305 million Series B round. The top five also included companies in the AI observability and financial spaces.

Smaller funding raises that did not quite make our top 5 this week included announcements from the HR, fintech and automotive sectors.
