Funding round led by Dimension Capital, with participation from Stage 2 Capital, Flybridge Capital Partners, Ridge Ventures, Tokyo Black Venture Capital, and Vermillion Cliffs, along with several notable angel investors.
PORTLAND, Ore., Sept. 4, 2025 /PRNewswire/ — Fiveonefour, a leader in data and analytics AI and developer tooling, today announced it has raised $17 million in total funding. The funding will be used to accelerate AI agent development, expand support for enterprise customers, deepen technical partnerships, and invest in growing their open source community.
As AI agents accelerate in adoption, enterprises face mounting pressure to modernize their data infrastructure to support real-time analytics and intelligent features. IDC reports that AI-enabling tech spend will hit $337 billion this year, with most Global 2000 companies adopting high-performance data systems by 2027. Fiveonefour enables developer teams to quickly and effectively deliver the specialized analytical infrastructure needed to power AI insights at conversation speed. For example, F45 Training — a Fiveonefour customer — powers its Lionheart biometric analytics feature with the platform, which delivers real-time performance insights and personalized workout feedback. Members who engage with Lionheart are 2.5X more valuable than average, making them F45’s most loyal and engaged users.
“Modern analytical use cases need more than a classic data warehouse with some dashboards,” said Tim Delisle, CEO and Co-Founder of Fiveonefour and former VP of Engineering at Nike. “AI agents and custom applications demand flexible, performant infrastructure coupled with developer and AI-friendly software interfaces like APIs and MCPs. We believe the future of data and analytics depends on the core developer experience for humans and AI agents alike, and this capital helps us deliver on that mission.”
At the heart of Fiveonefour’s offering is the Moose Stack, a fast-growing, open-source developer toolkit in TypeScript and Python, designed for developers building analytical backends. By abstracting away the complexity of data infrastructure, the Moose Stack enables software teams to rapidly integrate AI-ready analytics and operational data capabilities directly into their applications. Momentum has exploded, with installs doubling month over month, and enterprises across healthcare, manufacturing, and connected fitness are already using the Moose Stack to power user-facing analytics and AI-enabled data systems.
“In a world of AI hype, Fiveonefour is unlocking one of the biggest challenges in the enterprise today: developing and leveraging a solid data foundation to solve real problems with AI,” said Nan Li, Founder and Managing Partner at Dimension Capital. “With its open source core and focus on the developer, Fiveonefour is uniquely positioned to push data and analytics into the bright AI future.”
Fiveonefour’s full product suite – including Boreal, a fully managed cloud infrastructure platform, and Sloan, AI agents and tooling for data & analytics – makes it simple for human and agentic developers to adopt and integrate specialized analytical infrastructure into their existing applications. Current technical partners and supported technologies include ClickHouse, Kafka, RedPanda, Temporal, and Redis. With this new funding, growing enterprise adoption, and a thriving open source community, Fiveonefour is scaling to become a cornerstone of the modern AI and analytics stack for developers.
