Fiveonefour, a rapidly growing company at the intersection of data infrastructure and AI developer tooling, has announced it has raised $17 million in total funding. A group of prominent venture firms led the round, marking a significant step forward for the Portland-based startup as it continues to scale its platform and deepen its impact across industries.
The timing of this funding reflects a broader shift in how enterprises are approaching AI adoption. As AI agents move from experimental prototypes to core components of business operations, companies are under increasing pressure to modernize their data infrastructure.
Fiveonefour is helping developers meet this challenge head-on. Its platform enables software teams to quickly deploy the specialized analytical infrastructure needed to support AI insights at what the company calls “conversation speed.” This means delivering data and intelligence fast enough to power real-time interactions, whether through chat interfaces, biometric feedback, or embedded analytics in consumer applications.
One example of this in action is F45 Training, a fitness brand that uses Fiveonefour’s platform to power its Lionheart biometric analytics feature. Lionheart provides members with real-time performance insights and personalized workout feedback, helping them stay motivated and engaged. Members who use Lionheart are 2.5 times more valuable than the average user, making them the most loyal and active segment of F45’s customer base. This kind of impact illustrates how AI-enabled analytics can drive meaningful business outcomes when paired with the right infrastructure.
At the center of Fiveonefour’s technology is the Moose Stack, an open-source developer toolkit built in TypeScript and Python. Designed for teams building analytical backends, the Moose Stack abstracts away the complexity of managing data infrastructure, allowing developers to focus on building features rather than wrestling with pipelines and databases. Adoption has been rapid, with installations doubling month over month. Enterprises in sectors like healthcare, manufacturing, and connected fitness are already using the Moose Stack to power user-facing analytics and AI-enabled systems.
Beyond the Moose Stack, Fiveonefour offers a broader suite of products that make it easier for both human developers and AI agents to integrate analytics into their applications. Boreal, the company’s fully managed cloud infrastructure platform, provides scalable backend support, while Sloan offers AI agents and tooling specifically designed for data and analytics workflows. Together, these tools form a cohesive ecosystem that simplifies the process of building and deploying intelligent applications.
Fiveonefour’s platform is also deeply integrated with leading technologies in the data space. Current technical partners include ClickHouse, Kafka, RedPanda, Temporal, and Redis, providing developers with a robust set of tools for managing real-time data, event-driven architectures, and distributed systems. These integrations ensure that Fiveonefour’s solutions can plug into existing enterprise environments while offering the flexibility needed to support next-generation applications.
How the funding will be used: The capital will be used to accelerate the development of AI agents, expand enterprise support, strengthen technical partnerships, and invest in the growth of its open source community. And Fiveonefour is poised to scale its operations and expand its reach.
KEY QUOTES:
“Modern analytical use cases need more than a classic data warehouse with some dashboards. 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.”
Tim Delisle, CEO and Co-Founder of Fiveonefour and former VP of Engineering at Nike
“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. With its open source core and focus on the developer, Fiveonefour is uniquely positioned to push data and analytics into the bright AI future.”
