Cursor at Grab: Adoption and impact

Grab achieved 98% monthly active adoption of Cursor across their engineering org in just months. That's nearly 30 points higher than industry benchmarks for high-performing teams.

Grab's engineering team shares how they scaled AI coding assistants across 800+ cities in Southeast Asia. They took a multi-tool approach rather than betting on a single solution, and the results speak for themselves.

Key Takeaways

• 50% suggestion acceptance rate, beating the 30% industry average significantly
• Over one-third of merge requests now use Cursor in some capacity
• Non-engineers now ship production code: designers merged hundreds of PRs independently
• Custom monorepo indexing and Grab-specific rules made suggestions actually relevant
• Tasks that took full days now complete in hours

They're running fixed-effects regression analysis to measure actual productivity impact, and early data shows a dose-response relationship with usage intensity.
