**Type:** Problem & solution

## Summary

Grab established a dedicated Growth Hacking team within its Technology organization to pursue high-risk, niche initiatives and scale impact across 68 million regional users. Positioning the team within engineering allowed rapid A/B testing and simultaneous multi-market deployments driven by structured growth loops. The team prioritizes and evaluates all initiatives using a Growth Factor metric, calculated as the increase in rides divided by the increase in costs. To improve driver engagement, the team implemented a Spin-to-Win game based on B.F. Skinner's variable ratio reinforcement principles, delivering probabilistic monetary and merchandise rewards upon meeting daily ride thresholds. Ongoing regional experiments continue to evaluate metrics including driver acceptance, cancellation rates, and driver ratings.

## Context

Grab needed a dedicated space to take intelligent risks, run rapid experiments, and tackle high-impact scaling challenges that business teams considered too niche or risky.

## Approach / What changed

Grab embedded a Growth Hacking team within its Technology organization to build multi-market growth loops and deployed gamified A/B tests, such as the Spin-to-Win driver incentive game, evaluated against a cost-efficiency Growth Factor metric.

## Takeaways

- Grab measures experiment success using the Growth Factor, defined as the increase in rides divided by the increase in costs, where a value greater than one indicates cost-effective expansion.
- Housing growth hacking within Technology instead of Marketing enabled the team to leverage engineering capabilities for simultaneous deployments and rapid A/B testing.
- The Spin-to-Win driver initiative applied B.F. Skinner's variable ratio reinforcement theory to balance engagement through probabilistic monetary and merchandise rewards for completing daily ride targets.
