Asana has replaced an outdated internal test system using OpenAI Codex, taking around two weeks instead of the originally estimated five years. According to OpenAI, the project’s costs were around 12,000 US dollars.
According to a customer case study published by OpenAI, Asana used the AI coding agent Codex to replace an outdated test system in its own software development. The migration, which was originally internally estimated to require five years of effort, was completed within two weeks, according to OpenAI. The resulting costs are stated to be around 12,000 US dollars. The source does not provide further technical details on the specific scope of the migration, the number of affected lines of code or test cases, or the exact deployment model used for Codex.
For CTOs, this case is relevant because it serves as a reference point for evaluating AI-supported agents in large-scale but repetitive migration tasks – such as replacing legacy test infrastructure, a task that many companies permanently postpone due to capacity constraints. The stated cost and time savings are of an order of magnitude that could change traditional prioritization decisions between feature development and technical debt, provided that comparable results can be reproduced in other environments.
From a governance perspective, it remains unclear how quality assurance of the code generated by Codex was carried out, which review processes Asana went through internally, and whether this is a one-off, particularly well-suited scenario or a generalizable pattern. Since this is a customer reference communicated by OpenAI itself, the figures mentioned should be regarded as a vendor’s marketing statement and verified through independent benchmarks or pilot deployments within one’s own organization before drawing conclusions.
