Are you implying that the revenue multiple on this acquisition is lower than openAIs and that they'd be making money by acquiring and folding into their valuation multiple? I think that's not the case and I would wager non existent.
This was an acquihire (the author of ripgrep, rg, which codex uses nearly exclusively for file operations, is part of the team at Astral).
So, 99% acquihire , 1% other financial trickery. I don't even know if Astral has any revenue or sells anything, candidly.
They raised 4M USD, they have 26 full-time employees (they pay 120<->200K / yr, cf https://pitchbook.com/profiles/company/523411-93 ).
It means the company almost reached their runway, so all these employees would have to find a job.
It's a very very good product, but it is open-source and Apache / MIT, so difficult to defend from anyone just clicking on fork. Especially a large company like OpenAI who has massive distribution.
Now that they hired the employees, they have no more guarantees than if they made a direct offer to them.
