There Is No Tier-One Support

Headius Enterprises was established in 2024, but the work goes back to 2004. This isn't a pivot or a side project — it's a formalisation of support that was already happening informally for two decades.

The Short Version

Most support companies start with a product and then hire people to answer questions about it. We did it backwards. Charlie has been building JRuby since 2004, contributing to the JVM ecosystem since Java 1.0, and helping teams debug their deployments for free for most of that time.

In 2024, we made it official. Not because anything changed about the work — because enough people were relying on it that it deserved a proper structure. When you contact Headius for help, the person who responds is the same person who'll commit the fix. There's no handoff, no translation layer, no game of telephone between your problem and the solution.

We're a small team. Deliberately. No account managers, no support tiers staffed by people who've never seen the source code. The constraint is our advantage — every interaction is with someone who has deep, first-hand knowledge of the runtime your application depends on.

No other company in the world can match this level of expertise when it comes to JRuby. That's not marketing — it's just a fact about a twenty-year-old open source project with a very small number of core contributors.
