UK Travel Booking Firm Holiday Extras Reports 32.5% Conversion Boost After Rebuilding App with OpenAI Codex
Holiday Extras self-reports cutting app rebuild time from 6 months to 2 weeks with Codex, reducing error rates to 9% and boosting conversion by 32.5%.
UK-based travel booking platform Holiday Extras stated in an OpenAI case study that it used OpenAI's coding tool, Codex, to rebuild its mobile application. According to the company, this process reduced development time from over six months to just two weeks.
Holiday Extras reported specific performance improvements: the main app's "open-to-book" conversion rate increased by 32.5%, and the app error rate dropped from 19% to 9%. Additionally, release frequency shifted from annual major updates to multiple weekly releases.
CEO Matthew Pack and VP of AI Innovation Liam Thompson noted that Codex enabled non-engineering staff to participate in software building, allowing customer insights to be directly translated into product features. For instance, after a customer left a one-star review due to a missing list view, the team quickly implemented a fix using Codex, leading the customer to change their rating to five stars.
It should be noted that all cited data are self-reported by Holiday Extras and have not been independently verified.
