Top 5 VC Deals of the Week in AI (9/19/25)

This week’s venture capital funding announcements exceeded our expectations, led by six or seven transactions, depending on how you figure them, which exceed the $100 million threshold.

The top reported deal, per FinSMEs, came from San Francisco-based Replit, which raised a $250 million round in part to “scale operations, accelerate product development, and global expansion,” according to its announcement. Our second-place announcement comes from the AI robotics space, where Dyna Robotics, based in Redwood City, Calif., brought in a $120 million Series A. The top five also included companies in the enterprise AI, cybersecurity and materials science sectors.

This is an unusual week. All things otherwise being equal, one of the top two deals would certainly have been the recently announced raise by Figure AI which took their total committed capital over the $1 billion mark. We believe they raised somewhere in the realm of $120-275 million, however, like many AI companies, Figure AI didn’t provide the specifics of its funding round, thus we left it off of this week’s rankings. For those who don’t know, Figure AI develops autonomous, general purpose humanoid robots.

Smaller funding raises that did not quite make our top 5 this week included announcements from the software development, video, and enterprise AI spaces.
