LinkedIn: Are VC Round Sizes Shrinking or Exploding Right Now

VC round sizes are exploding - or are they?

How much cash VC-backed companies raise in a given round is an interesting trend indicator. At the moment there are two competing theories of startup cash needs.

๐—ง๐—ต๐—ฒ๐—ผ๐—ฟ๐˜† ๐Ÿญ AI is making everything about company-building cheaper. Startups need less cash than ever before.

๐—ง๐—ต๐—ฒ๐—ผ๐—ฟ๐˜† ๐Ÿฎ AI is lowering the barrier to company creation, thereby increasing competition, thereby making the cash advantage actually more important as startups scale. Yes you can get started for less but ultimately winning a category will cost more than ever.

What does the data say?

In the chart below, we compared the size of a US primary round in each venture stage (seed through Series E) raised in 2020 vs 2024.

Of course lots of stuff has happened in those 5 years. So we show both the absolute difference (in the black bars) and the inflation-adjusted difference (in orange).

๐—™๐—ถ๐—ป๐—ฑ๐—ถ๐—ป๐—ด๐˜€

  • Seed rounds (at least the priced version) have gotten much bigger. 53% bigger in aggregate, 31% inflation-adjusted, but any way you slice it seed rounds have done some healthy growing.

  • Every other stage besides Seed has either been effectively flat or actually shrunk when you look at inflation-adjusted round sizes. Late-stage rounds are 40%-50% smaller than they used to beโ€”and yes, that includes many wildly large AI fundraises.

  • Not shown in the chart but important: pre-seed funding on SAFEs has ballooned over this period, meaning the standard venture saying "Seed is the new Series A" should actually be "Pre-Seed is the new Seed" probably.

Of course this is only comparing medians, so there's a whole range of round sizes across every stage. But it's fascinating to see that scale rounds seem to abide by Theory 1 while Seed is playing its own game.

Final idea here: the increased Seed round size ๐˜ฎ๐˜ข๐˜บ be due in part to companies explicitly raising a seed-strap round (name from Natasha Mascarenhas) where they only expect to raise a single venture round ever. New company build unlocked, perhaps.
