Hi! We are fully bootstrapped, and ZenML is the final result of a longer journey. When we started over three years ago we were running predictive analytics projects with industry partners. Over time our focus expanded, until we finally realized: our tech stack is much more valuable. We did a lot of talking to people to find out if there is a niche for our perspective, and have been pushing the code base to where it is today for the last months.

So, to answer in short: there is a longer development cycle behind this, but not in the open - and no VC backing.
