Venture capital continues to flow to startups developing artificial intelligence and generative AI technology. Here’s a look at 10 companies that successfully raised new funding in May.

Follow The Money

The venture capital space continues to show signs of exiting the slump it has been in since early 2022. But while startups in such technology areas as data analytics and next-generation networking are attracting investors, a great deal of VC money is going into startups developing products that in some way involve or incorporate artificial intelligence and generative AI technology.

Case in point is CoreWeave, the AI data center and infrastructure provider that tops the May Follow the Money roundup with an impressive $1.1 billion in Series C funding. Also making the list is AI “data foundry” company Scale AI at No. 2 with a $1-billion Series F funding round.

In a reminder that data is the lifeblood of AI systems, this month’s funding list includes a number of companies, including WekaIO and Atlan, that develop data management systems and technology that play a critical role in AI operations. The roundup also includes startups Sigma and Hydrolix that develop next-generation big data analytics software.

Also achieving a nine-figure funding round was Alkira, which develops on-demand network infrastructure technology that integrates diverse environments into one secure network fabric.

Today, millions of hours of meetings happen every day over video conferencing platforms and hundreds of AI companies try to make sense of them using AI-powered meeting bots. The problem is that these bots take teams of specialist engineers months to build.”
