Fiveonefour Raises $17 Million to Scale AI-Driven Data Infrastructure and Developer Tools
Fiveonefour, a Portland, Oregon–based startup combining data infrastructure, AI, and developer tooling, has announced it has raised US$17 million in total funding to scale its analytics and AI platform. The latest infusion is intended to help the company enhance its developer experience, expand enterprise reach, and deepen technical partnerships.
The funding round was led by Dimension Capital, with co-investment from Stage 2 Capital, Flybridge Capital Partners, Ridge Ventures, Tokyo Black Venture Capital, and Vermillion Cliffs Ventures. Angel investors also joined in this round, contributing to the company’s growth momentum.
Founded in 2023 by former engineers and product leaders from Nike, Fiveonefour has introduced a suite of tools aimed at simplifying how developers build analytical and AI-enabled applications. Its core offerings include Moose Stack, an open-source toolkit in TypeScript and Python for constructing analytics backends; Boreal, a managed cloud infrastructure platform; and Sloan, a set of AI agents and tooling that automate analytics workflows while integrating with developer pipelines.
Prior to this round, Fiveonefour had already secured earlier investments. The latest $17 million represents the cumulative capital raised across its early-stage financing journey. The company is backed by venture firms such as K5 Global, Stage 2 Capital, and Vermillion Cliffs, among others.
Among Fiveonefour’s customers is F45 Training, which uses the company’s platform to power its Lionheart biometric analytics features. Through the integration, F45 provides real-time insights and personalized feedback to its users, enhancing user engagement and product value.
With the new capital, Fiveonefour plans to accelerate development of its AI agents, scale infrastructure support for enterprise customers, strengthen its open source community, and invest in its engineering and product teams. The company aims to deepen its integrations with data systems and frameworks such as ClickHouse, Kafka, RedPanda, Temporal, and Redis, enabling seamless adoption by developer teams already using these technologies.
In a competitive market where organizations increasingly demand AI-native analytics infrastructure, Fiveonefour’s strategy focuses on reducing friction for developers. By offering modular components and automated tooling, the startup positions itself as a bridge between raw data stacks and application-level intelligence. The backing from leading VCs and growth capital firms underscores confidence in its vision and execution capability.
As Fiveonefour proceeds with this funding, its challenge will shift toward translating product innovation and open source adoption into sustainable enterprise revenue. The company’s bet is that a developer-first platform, paired with AI agents and embedded analytics support, can differentiate it in a crowded infrastructure space. With $17 million in capital, Fiveonefour now has the resources to expand operations, attract top engineering talent, and scale both technically and commercially.
