Who We Are

Halzer Group is a private software company, founded in Washington, D.C. in 2019. We have never taken venture capital. We have never taken on client work. We build products, ship them when they are ready, and improve them based on what users actually experience - not what a quarterly roadmap requires.

Our conviction is simple: most professional software is embarrassingly bad. It was built for feature demos and enterprise procurement, not for the person who has to use it for eight hours a day. We build for that person. Each of our products addresses a domain where the gap between what software does and what it should do is measurably, consequentially large. Read more about how we work →

“We believe the most powerful software is the kind that disappears into the work - so capable, so precise, that users forget it is there at all.”
