So now that I know what kind of company the AAF *actually* is... time to go look at Crunchbase!
https://www.crunchbase.com/organization/alliance-of-american-football
Sole investor of the first seed round, January 2018, was M Ventures out of Menlo Park, founded in July 2017. Not a big hitter. 68 investments, only 1 exit to date -- not that surprising given their young age, but not great either. More a media investor than a tech investor, looks like. $7m to bootstrap operations.
Next round was April 2018, an additional $10m seed, with 4 additional investors:
* The Chernin Group, mostly a media investor looks like (EDIT: ahhh, they acquired Barstool in 2016!)
* Slow Ventures, 376 investments, 65 exits. Notable exits: Twitter, New Relic, Nest, Pandora.
* Founders Fund, 439 investments, 115 exits. Notable exits: Facebook, Lyft, Spotify, Twilio, SendGrid.
* Individual investor Keith Rabois, who is a partner at Khosla, one of the *big* dogs.
So $17m in three months. That's a small round. For a tech company alone it's a decent A or even B round, but it's clearly designated as a seed round, and for a weird AAF-shaped thing that was potentially capital-intensive, that makes sense.
There may have been subsequent investment rounds that never made Crunchbase -- obviously Dundon's investment would apply -- and I read somewhere that MGM was an investor, but they may have been investing through one of the venture funds rather than directly. Let there be no doubt, though: this was a tech company all along. Not a football company.
Of course, if there were no additional investors, then Dundon's $70m is a *lot* in comparison, and may represent a buyout of the original investors at 4x. Not a bad return for a seed round investor who wants out of an increasingly money-hungry and speculative investment.
