CoreWeave Ventures, the newly‑established venture arm of the AI‑cloud provider CoreWeave, has joined a seed‑stage investment round for Numerata, a startup that builds AI‑powered software development tools. The round was led by Jane Street, with CoreWeave Ventures participating alongside other early investors. While the exact capital commitment was not disclosed, the participation signals CoreWeave’s intent to deepen its footprint in the developer‑tools layer of the AI stack.
Numerata’s flagship product, NinetyFive, delivers secure, low‑latency autocomplete and custom model training for enterprise codebases. The platform is designed to augment human developers rather than replace them, keeping code and data within the enterprise environment to address privacy and intellectual‑property concerns. By integrating NinetyFive with its high‑performance compute infrastructure, CoreWeave can offer a more seamless AI‑cloud experience to its customers.
The investment aligns with CoreWeave’s broader strategy of building a full‑stack AI ecosystem—from purpose‑built hardware to software that accelerates model development. CoreWeave already serves major clients such as Microsoft and Meta, and the partnership with Numerata positions the company to bundle developer tools with its infrastructure, potentially increasing customer stickiness and expanding its addressable market in the enterprise AI space.
CoreWeave’s financial backdrop underscores the significance of the investment. The company’s valuation reached $23 billion in November 2024, and it has raised $2.37 billion across 13 funding rounds, including a $650 million debt round in October 2024. With a backlog of contracted revenue exceeding $56 billion, CoreWeave has the capital and scale to support portfolio companies and drive ecosystem growth.
Kevin Wang, Numerata’s founder, said the partnership validates the company’s vision: “Having Jane Street as a flagship customer and CoreWeave as a cloud partner and investor confirms that customized AI models can be as accessible as open‑source software while keeping code private.” Brannin McBee, Cofounder and Chief Development Officer of CoreWeave, added, “CoreWeave Ventures backs founders who are redefining what’s possible in AI by connecting innovative capital with access to the CoreWeave AI Cloud. Numerata exemplifies the technical ambition we look for.”
The formation of CoreWeave Ventures earlier in September 2025 already sparked a 20 % jump in the company’s share price, reflecting investor enthusiasm for its ecosystem strategy. While no immediate market reaction has been reported for the Numerata investment, the move reinforces CoreWeave’s commitment to building an integrated AI platform and signals continued confidence in the enterprise developer‑tools market.
