Since the rise of of on-demand data centers and software eating the world, Series A is the new Series B, and they expect some commercializable prototype (MVP) and customer traction before they'll talk to you.
So, even though Series A used to be called "Early stage" financing, I'm not sure it's fair to include it in what we used to call early stage any more.
So, to your question: sticking with angel/fund/corp seed, I don't know - maybe $10B or so in the US? You're right - that's pretty tiny. VC as an entire asset class is pretty tiny in the grand scheme of things (certainly very tiny for the amount of press it generates).
I'll take a look into the data this weekend, but I would guess that I'm in the ballpark of a binary order of magnitude with that guesstimate. Close enough to zero to make scrounging for it painful, I agree.
No, that's not even good enough. Even if you have a product in the market, with traction, if it's not millions of MAU/DAU then welp you're SOL. Doesn't matter what technology you built or how good your team is.
The only caveat to that is if you, as a founder, are already a known entity to the venture funds with a previous exit or in the right social network.
Currently I have a thing that is kinda/sorta like a B2B SaaS play, with bottom-up engagement directly with the employees of the target enterprise -- and I've had to shut the doors to (unnecessary) investor interest w/ only about 3K active users.
But, underneath it all the distracting details, I agree. I think the general consensus in this thread is: it's hard.
I will go see what I can see. As for a starting point, I'll probably dig around CB insights, pitchbook, angellist, and the Center for Venture Research at UNH (New Hampshire). Then go from there.
If you are right, that's a very very interesting result.
The lines have gotten so blurry compared to 20 years ago (entrepreneural creativity in action?), so sorting out the wheat and chaff is harder. More data - less definition.
Briefly, most of the published analysis is top-down and less is bottom-up. People seem to bundle Seed+Series-A in most places. There's a lot of talk about medians without a deal-count. There are counts for numbers of deals with a size exceeding some threshold, but that doesn't give us what we're looking for.
Here's a chart - US only: - https://files.pitchbook.com/images/Angel.Seed%20Activity.png
At about a thousand deals at about a million bucks, that's bumping the $1B mark, but doesn't break $2B.
Also if you'd like you can email me at the address in my profile, this thread is getting nested very deep.
I asked you to sum up all seed funding in existence: what number did you get? (This is the number that I call next to zero.) It doesn't matter what year you pick.
