Announcing our new name, Zettascale, & progress

Minor update, rebrand, and making Zettascale computing sustainable.

September 04, 2025 11:30:00 AM PDT

announcement
update

"Exa Laboratories" is now the "Zettascale Computing Corporation", or "zscc" for short.

Long story short: We've been quiet for almost a year now, heads down building, raised our seed round (a good couple of million dollars, hiring btw) in September 2024, and we've been quietly accumulating breakthroughs and cooking up something you won't want to miss.

We will announce some of it soon-ish. Stay tuned.

So, why the change? Because exascale computing is no longer ambitious enough, due to recent internal breakthroughs. Zettascale computing is a much better goal. We now live in a post-exascale era.

We were making the ExaFLOP sustainable, but now we are making Zettascale computing sustainable (hence the name).

Same mission: building the hardware substrate for all future AI.

Back to building.
