This is the claim in the repo readme that presumably unlocked the VC investment:

“TensorZero is used by companies ranging from frontier AI startups to the Fortune 10 and fuels ~1% of global LLM API spend today.”

One percent seems like a lot. Anyone on HN use this?

We raised most of the capital before we had any traction. We raised on a rolling basis and had millions in the bank before we had even published the open-source repository. Ultimately we raised based on the team's background + vision.

The ~1% figure might be outdated today but it was a best-effort estimate a couple of months ago. TensorZero powered tens of trillions of inference tokens per month. TensorZero is not widely used but it was used by a couple of extreme-scale users.

Thank you, appreciate the response. It’s a great part of the HN community that there’s almost always someone around with the first-hand experience and facts.

Best of luck with whatever you do next!

I used it, but only briefly to evaluate it. It had some overlap with a tool I built myself, was curious if any of the extra features would be useful.

Ultimately I found the data model and UI to be both cumbersome and unintuitive. Langfuse ended up being the observability tool I went with instead over the one I built (and still use today).

Generally speaking, every YC company post ~2020 is forced to make pathologically false claims to compete in the (fundraising) market.

Just tell AI to write your copy and that's what you get, overhype-as-a-service.
