Harrowsoft

Business software

Rebuilt from
the ground up.

Harrowsoft remakes the software companies rent for too much. Simple enough to learn in an afternoon, fast enough to run on very little, and built so AI can do the busywork while you stay in charge.

First crop, now open: Thermostat, for A/B tests and feature flags

Thermostat

A/B tests and feature flags that tell you what happened, in a sentence.

  • Answers, not dashboards. Every experiment ends in one plain sentence, with the math a click away.
  • An AI that runs the test. Say what you want to learn. It drafts the test, ramps traffic, watches your guardrails, and emails you when it's time to decide.
  • Move from Statsig in minutes. Bring your gates, experiments, segments and metrics, and keep users in the same variants.

Principles

“Is this truly needed?”

We ask it about every button, setting and page. Most of the software you rent was never asked.

Small and quick

Written in Rust and built to run on modest hardware. Less to operate means less for you to pay for.

AI with a supervisor

Our AI does real work, and it shows you what it will change before it changes it. Everything it does goes in the audit log.

Yours to leave
