Cult.fit standardises on Codex; non-engineers ship 20+ apps

India fitness company cult.fit (708 centres, nearly 1 million paid members) standardised engineering on OpenAI Codex, then extended it beyond engineering. Non-engineering teams have built more than 20 internal apps in recent months, including an HR performance-review workflow. One engineer rebuilt internal dashboard software over a weekend after a vendor price rise, avoiding more than $100,000 a year in software costs. Cult.fit also reports a more than 50% cut in customer support costs after putting AI agents into Sprinklr for cases such as missed-class penalty waivers. Figures are cult.fit's own, via OpenAI's customer post.
