No room for error – A case study of Gleam in production at Uncover (gleam.run)

Uncover, a São Paulo-based company, has launched a transformative platform for marketing mix modeling (MMM), enabling businesses of all sizes to access advanced data integration and AI tools. Traditionally dominated by costly consultancy firms, MMM is now more accessible due to Uncover's innovative approach, which allows for real-time tracking of marketing investments and their effectiveness without violating customer data privacy. Uncover's platform employs a powerful query engine capable of delivering timely insights, shifting the landscape of marketing analysis. To enhance its backend capabilities, Uncover adopted Gleam, a programming language known for its strong error detection and safety features. This decision addresses the significant coding bugs prevalent in their previous backend system. Gleam not only ensures reliability—allowing pseudo-bulletproof queries—but also increases the efficiency of testing, enabling an impressive 1,900 tests per second. As Uncover continues to grow, it plans to leverage Gleam further for additional functionality, including potential usage in front-end development, fostering a cohesive and robust programming environment that could evolve as the Gleam community advances.
