The read
Three weeks and three days after the Jev launch post, TypeSafe AI co-founder Diogo Almeida posted the round from his own account: a Series A led by a16z, which Bloomberg reported the same day at about $870 million and a $7.5 billion valuation, with Sequoia and a group of angels taking part.
The post is six lines: launched a model, served trillions of tokens a day by accident, 29.4% of the Fortune 500 showed up, raised a really big Series A from a16z, it has been three weeks, we would like to sleep now.
The figures are the company's own. The 29.4% of the Fortune 500 line sharpens the "about a third" that Bloomberg carried, and the trillions of tokens a day is the first usage figure TypeSafe has put a unit on.
The account that posted it had 1,500 followers on 15 September and has 156K now, which is the audience the launch built and the reason a six-line post with no video reaches 1.3M people in its first hours.
A funding announcement from a founder's own account, written as a list of what happened rather than as a press release, is the shape the directory's best raise posts share. Read against every funding announcement we track, the number to watch here is reposts and quotes over the first two days rather than views.
The full timeline from the seed to the round is in TypeSafe AI's valuation and the 24 days before it, and the launch three weeks earlier is in the TypeSafe AI case study.
