Rails Business

In this episode, Kyle Keesling, co-owner of PASS Testing and long-time solo Rails developer, shares how PASS grew from a college web design side project into a niche software and training business for the Underground Storage Tank (UST) industry. The conversation covers why they kept the products as two apps connected by a read-only private API, what makes compliance software hard, and how they modeled flexible equipment and inspection data—evolving from STI to Rails delegated types. Kyle also discusses early scaling pains around billing and payments, how feature requests are prioritized with help from their CRO and a contractor, and how tools like Claude Code are changing his workflow while maintaining PR-based review and safer deployment practices.
