Unison Computing's seed funding and why our investors are special

We've raised $9.75 million in seed funding and I'd like to say some nice things about the people financially supporting our work. This won't be your typical funding announcement; instead I'll talk candidly about some of the dynamics of VC and open source funding today and why the people investing in Unison are so rare, and so special. I hope you'll come away feeling the same.

Unison in production at Unison Computing

The Unison ecosystem, tooling, and core language experience is currently mature enough that we're using Unison in production—on mission-critical applications. But along the way, we encountered a number of stumbling blocks that required careful developer investment. This post is our candid experience report on what we ran into, what we fixed, and what we're excited about tackling next.

It's time to rethink complicated cloud pricing

Cloud pricing has gotten complicated, and this doesn't serve the needs of most users. What does? Platforms with simple, predictable pricing, and good developer productivity.

Developer productivity is what really matters for a cloud platform

Most companies spend far more on developer compensation than on their cloud bill. So why isn't there more focus on improving developer productivity for cloud platforms and tools?

How Unison reduces ecosystem churn

Unison doesn't have library dependency conflicts, and many sources of ecosystem churn just disappear. This fact got a brief mention in the Strange Loop 2019 talk, but that talk didn't make all the benefits totally clear. This article will attempt to highlight some of the more surprising benefits of Unison's approach.
