Concurrent AB tests driving product innovation

Using Sigma, I was able to make a dashboard in under twohours that got the answers to my questions... we want people to answer their own questions without needing to rely on a data scientist.

The Challenge: Bottlenecks Stifling Curiosity

With 48 million daily active users generating petabytes of data, Duolingo's existing in-house analytics toolswere designed primarily for technical users like engineers. This created bottlenecks as other departmentsneeded data for strategic decision-making.

The Solution: Intuitive, Secure Access

Duolingo leveraged Sigma's spreadsheet-like interface to make data exploration intuitive for non-technicalusers. The platform's row-level security enabled granular access controls, allowing managers to view theirteam's data while protecting sensitive information.

The implementation of Input Tables transformed manual processes in people analytics, allowing teams toannotate anomalies and maintain audit trails directly within Sigma.

The Results

The transformation delivered measurable results across the organization. The data team freed 15+ engineers from routine reporting tasks, enabling them to focus on strategic initiatives. The platform now supports 300+ concurrent AB tests, enabling rapid experimentation.

Within 90 days of implementation, Duolingo achieved 91% active user adoption—a testament to Sigma'sintuitive interface and the value it provides to teams across the organization.
