April’s Most Active US Investors Included Some Usual Suspects, And Some Unusual Ones

These are strange times for startup investment. Standard seed and venture rounds in the millions or tens of millions are still happening at a steady clip. At the same time, AI leaders still young enough to qualify as startups are securing investments and valuations at exponentially higher sums.

The result is a funding scene that is drawing sustained high activity from top-name venture firms as well as big checks from relative newcomers and megacap strategic investors. That’s reflected in April’s tally of most active U.S. startup investors, with rankings topped by well-established VCs such as Andreessen Horowitz and Khosla Ventures, tech giants like Google and Amazon, and a few names that don’t commonly show up in the lists.

To illustrate, we used Crunchbase data to aggregate most active investor rankings across multiple metrics, including venture deal count, lead rounds, and highest value lead rounds.

Most active venture investors

We’ll start with most active venture investors, looking at those who participated in the largest number of startup funding rounds for $5 million or more at any stage.

By this metric, Y Combinator came out on top, with 11 rounds. The famed accelerator commonly tops this ranking as it participates as a non-lead investor in follow-on rounds for startups it incubated.

Khosla Ventures and First Round Capital tied for second, with nine rounds each, followed by Neo and General Catalyst with seven rounds each. Below we rank the top X most active venture investors for the month:

Neo’s inclusion is noteworthy as it’s a newcomer to the top of the ranks. The San Francisco incubator has an investment model that shares similarities with Y Combinator, providing mentorship and seed funding to upstarts and securing participation rights for follow-on rounds.

Another standout high in the rankings with six deals was Gaingels, an investor focused on diverse and inclusive teams that has strong ties to the LGBTQ+ community. Gaingels has long been a prolific seed investor and participant in follow-on rounds. But as average deal sizes overall rise, Gaingels’ follow-on rounds have been getting bigger too.

Most active and highest spending lead investors

Among lead investors, Khosla Ventures took the top slot, with a lead- or co-lead role in seven April rounds exceeding $5 million. Andreessen Horowitz was the next-busiest lead investor, with five deals.

For a bigger-picture view, below we list the top X most active lead investors for April:

When we turn to highest-spending lead investors, the ranks shift some. This list looks at investors who led or co-led rounds with the highest aggregate value in April.

It’s not an exact tally of who put the most capital to work, given that syndicate rounds don’t break out each lead investors’ share. However, it does provide a general idea of the heaviest spenders.

For April, Google was the single largest lead investor, thanks to its reported $10 billion investment in Anthropic, a deal that includes terms for another potential $30 billion to come. Amazon was next on the list, with a $5 billion Anthropic investment of its own, and up to $20 billion to come, as part of a broader partnership for compute power.

Next on the list were two that don’t typically top our ranks: Drive Capital and Access Industries. The two firms co-led a $1 billion April Series F for AI data and computing platform Vast Data at a $30 billion valuation.

Overall, a bit slower

While the April active investor data doesn’t scream “slowdown,” the month was nonetheless somewhat less busy than March in terms of deal counts by top dealmakers. Given that AI enthusiasm has not dissipated and massive deals continue to get done, it’s not clear that is an indicator of changing investor appetites.

For now, we’ll avoid reading too much into month-to-month fluctuations and wait to see whether further tallies point to a broader change in the investment climate.
