Fiveonefour offers an open-source developer toolkit (the Moose Stack) plus a managed cloud platform (Boreal) and AI agents/tooling (Sloan) to simplify building analytical backends. The Moose Stack is a fast-growing TypeScript and Python toolkit that abstracts data infrastructure complexity so developers can integrate AI-ready analytics directly into applications. Installs of the Moose Stack have doubled month over month, and customers across healthcare, manufacturing, and connected fitness use the stack for user-facing analytics. F45 Training uses Fiveonefour to power its Lionheart biometric analytics feature; members who engage with Lionheart are 2.5X more valuable than average. Fiveonefour cites integrations with ClickHouse, Kafka, RedPanda, Temporal, and Redis and emphasizes developer- and agent-friendly APIs and MCPs. The company plans to accelerate AI agent development, expand enterprise support, deepen technical partnerships, and invest in its open-source community.
