Jane Street, a global technology-driven trading and investment firm, announced it led a seed investment round in Numerata, a developer of AI-powered software development tools. CoreWeave Ventures also participated in the funding round.
Numerata’s technology is designed to enhance developer productivity and mitigate costly errors through custom model training techniques and a low-latency autocomplete backend. Its flagship product, NinetyFive, aims to make computation a natural extension of thought.
Kevin Wang, Founder of Numerata, stated, “Our approach recognizes that human developers will remain core to software development, and new productivity gains come from tools that augment human expertise rather than replace it. Having Jane Street as both our investor and a flagship customer and CoreWeave as a cloud partner and our investor validates our vision of making customized AI models as accessible as open-source software.”
A representative from Jane Street commented on the firm’s expanding commitment to supporting transformative technology companies as both a strategic partner and investor. The firm emphasized its approach of combining technical-first diligence with flexible capital, backed by extensive infrastructure expertise.
Brannin McBee, CoreWeave’s Cofounder and Chief Development Officer, added, “CoreWeave Ventures backs founders who are redefining what’s possible in AI by connecting innovative capital with access to the CoreWeave AI Cloud.” McBee described Numerata as embodying the “ambitious, technical vision we look for,” noting their progress in turning powerful ideas into breakthroughs. CoreWeave, established in 2017, operates as “The Essential Cloud for AI™” and completed its public listing on Nasdaq (CRWV) in March 2025.
Numerata’s NinetyFive product addresses a key concern in software development: allowing developers to utilize AI-driven innovations while ensuring privacy and control over proprietary codebases. Unlike many cloud-based services, Numerata’s AI/ML deployments provide secure custom model training capabilities. This allows enterprises to train models on their private codebases and then deploy these customized models for their developers, tailoring the tool specifically to the enterprise’s software.
Jane Street, founded in 2000, employs a research-driven approach and quantitative expertise across global markets, with offices in New York, London, Hong Kong, Singapore, and Amsterdam.
