Case Study: Twilio scales experimentation and speeds product decisions with Harness

Twilio scales experimentation for better product decisions with Harness

Twilio, a global leader in communication APIs, needed a better way to support rich experimentation across multiple use cases as it grew quickly and released high-impact features. To improve decision-making and measure feature impact more reliably, Twilio turned to Harness’s Feature Management & Experimentation product, using Split technology to help manage user assignments, record treatments, and integrate with its internal data systems.

With Harness’s Split-based full-stack experimentation platform, Twilio accelerated its experimentation rollout by six months, improved developer efficiency, and enabled faster, more informed product decisions. The team used the platform to run targeted tests and validate changes with data, including a sign-up flow experiment that showed additional questions significantly improved the experience after one month, helping Twilio improve adoption and iterate with greater confidence.
