Shares of GitLab Inc. (GTLB) jumped 7% in after-hours trading Tuesday following the company’s announcement of a deepened collaboration with Google Cloud that integrates Vertex AI models directly into GitLab’s Duo Agent Platform.

GitLab closed the regular session at $20.08. In extended trading, the stock climbed as high as $21.62, before tempering some gains. 

The partnership lets enterprise teams power GitLab’s AI agents with Google Cloud’s Vertex AI foundation models — including Gemini — while keeping all agent actions under GitLab’s existing compliance, audit, and governance controls.

Developers no longer need to manage separate AI infrastructure: GitLab’s AI Gateway can run natively on Google Cloud runtimes such as GKE or Cloud Run. Customers with Google Cloud spending commitments can also apply their GitLab Duo usage toward those budgets.
