Poolside Founding Team
Jason Warner and Eiso Kant started Poolside with software development as the first target for their AI research. Their plan was to train models to complete multi-step tasks in real coding environments, where a program’s behavior can be tested.
Poolside Company Development
The Laguna Family Gives Poolside’s Research a Public Output
Poolside set out to develop foundation models for software engineering. Its Laguna family gives that research a model release around which developers can evaluate coding and agent workflows.
Poolside Competitive Landscape
A Coding Model and a Coding Environment
Poolside develops the models behind software-engineering tasks. Cursor packages AI assistance inside an editor. Teams can compare the two only after deciding whether they need a model for their own workflow or an editor that engineers can adopt directly.
