ABOUT HOS CODEX
HOS Codex was built to remove compliance from product roadmaps so teams can focus on building features that actually differentiate their platform.
As fleet systems scale, Hours-of-Service compliance becomes one of the most complex parts of the stack. It requires deep regulatory knowledge, careful edge-case handling, and ongoing validation across both engineering and QA. In many cases, teams are forced to become HOS experts just to maintain functionality that isn’t core to their product.
HOS Codex changes that model.
Instead of every platform building and maintaining its own compliance logic, HOS Codex provides a dedicated, ruleset-aware API for accurate Hours-of-Service calculations and reporting.
This turns compliance into a managed capability, not an internal burden, so engineering teams don’t need to carry regulatory complexity in their roadmap.
Joel Bartenbach
Founder, HOS Codex
Senior Software Architect specializing in compliance-driven systems and rules engine design.
Joel has worked directly with a compliance team to design and build a production Hours of Service engine from the ground up. That experience exposed the complexity of translating regulatory requirements into reliable software—and the long-term cost of maintaining it.
HOS Codex is built from that firsthand experience, with a focus on clarity, consistency, and maintainability in compliance systems.
