Helicone got acquired. Langfuse got acquired.
Two of the most trusted tools in the LLM
observability space, gone within months of
each other.
I don't say this to criticize the founders.
Building and selling is legitimate.
But for engineering teams running AI in
production — especially in healthcare, finance,
and government where data cannot leave your
servers — every acquisition is a crisis.
So I stopped waiting for the next one.
