I'm trying to understand how Typesafe (Jev) raised $40M
Questioned how TypeSafe raised $40M given Jev's $0.042/M input and $0.00/M output pricing, even at 100 million users.
The original post
I'm trying to understand how Typesafe (Jev) raised $40M when their product is $0.042/M input and $0.00/M output. I'm sure there is more coming, but even if 100 million people are using it, it's peanuts.

Where this case fits
Filed under general Jev builds. In the pattern Jev is built for, the model answers a bounded question per step — and ordinary code acts on the answer, because the answer is already a value rather than a paragraph. Browse the full case library for the work it sits next to.
