Poolside

Poolside develops open-weight foundation models and the systems used to train and refine them. Its published models include the Laguna family, with Laguna M.1 and XS.2 released in research preview alongside a runtime for training and operating agents.

The company's website lists two product lines for customers: the Laguna models themselves and a government offering, "Bring frontier AI to your mission." The input does not describe pricing or detail the customer base beyond this.

The website lists an engineering blog, a careers page with open roles in Engineering (Inference Infrastructure) and Engineering (Infrastructure), both remote in EMEA, and a registry country of GB. The input does not give a founding year or office locations.

Product: Laguna open-weight foundation models (Laguna M.1, XS.2 and 2.1 variants) and an agent runtime in research preview.
