This is a monthly feature that runs down some of the most-active investors in U.S.-based companies, looks at some of their most interesting investments, and includes some odds and ends of who spent what. See May’s most-active startup investors here.

Venture investors kept busy in June, with a handful of firms leading the charge.

The list of most-active U.S. investors by deal count and dollars invested this past month includes mostly familiar names such as Sequoia Capital, Andreessen Horowitz and Founders Fund.

We also saw Meta join the ranks for spendiest, thanks to its $14.3 billion investment in Scale AI.

Below, we break down frontrunners by several metrics including highest-spending lead investor, busiest investors and most prolific seed dealmakers, per Crunchbase data.

Among venture investors, Sequoia Capital, Y Combinator, Khosla Ventures and General Catalyst led for deal count.

Sequoia Capital, in first place, did both a large number of deals and a lot of really big ones. Overall, the firm backed 15 venture rounds in June, including a $540 million Series E for cybersecurity provider Cyera and a $300 million Series E for legaltech startup Harvey.

Y Combinator, though best known as an accelerator, also has been moving up the ranks as a venture investor in later rounds for companies it helped incubate. It participated in 14 investments along these lines last month, including a  $125 million Series D for Gecko Robotics and an $80 million Series D for hospitality platform Canary Technologies.

Khosla Ventures and General Catalyst, meanwhile, filled out the the No. 3 and 4 slots, with 12 deals each, Crunchbase data shows.

Most-active and spendiest lead venture investors

Among lead investors, Andreessen Horowitz took the top slot for most-active dealmaker. The firm led or co-led five post-seed rounds in June, including a $300 million Series E for AI-enabled medical note-taking unicorn Abridge and a $131 million Series C for customer service AI platform Decagon.

Kleiner Perkins and Founders Fund, meanwhile, each led or co-led four deals last month. Kleiner’s largest co-led deal was a $600 million Series F for automotive software provider Applied Intuition.

Founders Fund’s biggest lead investment was a $2.5 billion Series G for defense tech unicorn Anduril. That deal also catapulted the firm into the second-place position as spendiest post-seed venture investor for June.

Meta, meanwhile, took the lead as the highest-spending startup backer with its $14.3 billion investment in Scale AI. The deal reportedly gives Meta a 49% stake in Scale and also calls for company founder Alexandr Wang and several other employees to join Meta.
