Cult.fit leverages Codex to boost internal efficiency and member experience

Cult.fit, a major fitness company operating 708 centers across 77 cities, is integrating Codex to streamline operations and accelerate development across its organization. The platform is enabling non-engineering teams to build over 20 internal applications, such as an HR workflow for performance reviews. This internal capability shift has resulted in over $100,000 in annual software cost avoidance, exemplified by rebuilding a dashboard functionality over a weekend. Beyond internal tools, the company is enhancing member interactions using the OpenAI API. This includes advancing its AI Trainer, which now features a voice-first experience via GPT Realtime for personalized guidance. Furthermore, AI is transforming customer support, allowing agents to automatically assess penalty waiver requests by checking factors like local weather. Santhosh Kumar, CTO at cult.fit, noted the goal is to become more AI-native in operations. The standardization on Codex initially unified engineering workflows, allowing a project like a social feed to be shipped in two months, a task previously estimated to take over a year. The company plans to evolve toward an 'autopilot operations org' and a 'trainer in your pocket' experience.
