The demand for AI-powered developer tools that respect privacy and enhance productivity is attracting strategic investment from industry leaders. Numerata, a developer of AI-powered software development tools, has announced a seed investment round led by global trading firm Jane Street with participation from CoreWeave Ventures. The investment, coupled with Jane Street as a flagship customer and CoreWeave as a cloud partner, aims to accelerate Numerata's vision of providing enterprises with customizable, private AI models for coding that augment rather than replace human developers.
Numerata secures seed investment led by Jane Street with participation from CoreWeave Ventures.
Jane Street is also a flagship customer; CoreWeave is a cloud/infrastructure partner.
Numerata's product, NinetyFive, offers custom AI model training on private enterprise codebases.
The focus is on low-latency autocomplete and tools that augment, not replace, developers.
The approach ensures code privacy and model customization, unlike generic cloud-based tools.
The founders aim to make "computation as an extension of thought."
Numerata's flagship product, NinetyFive, addresses a key enterprise concern: leveraging AI for coding without exposing proprietary code to third-party cloud services. Unlike generic coding assistants, NinetyFive enables enterprises to securely train custom AI models directly on their private codebases. These customized models then power ultra-low latency autocomplete and other assistance tools tailored to the specific patterns, libraries, and architecture of the company's own software, offering more relevant and secure assistance than off-the-shelf alternatives.
Kevin Wang, Founder of Numerata, explained the philosophy: "We are building computation as an extension of thought. 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."
The investment is notable for the deep technical and operational alignment between the partners. Jane Street, a quantitatively driven trading firm that builds complex global systems, is not just an investor but also a flagship enterprise customer, providing real-world validation. CoreWeave, a leading AI cloud infrastructure provider, contributes both capital and essential compute resources. This combination of strategic capital, a demanding customer, and specialized infrastructure is designed to rapidly accelerate Numerata's development and market fit.
Jane Street highlighted its holistic partnership approach: "Our approach combines a technical-first diligence with patient, flexible capital, backed by deep infrastructure expertise from building and operating global technology systems."
Brannin McBee, Cofounder and Chief Development Officer of CoreWeave, added: "Numerata manifests the ambitious, technical vision we look for. They're already turning powerful ideas into real breakthroughs."
This investment round underscores a growing trend where cutting-edge AI tooling is being built with enterprise-grade privacy and customization as foundational principles. By attracting backing from sophisticated technical entities like Jane Street and CoreWeave, Numerata validates a market need for AI development assistants that are not one-size-fits-all but are instead deeply integrated and tailored to an organization's unique intellectual property. This model could define the next generation of enterprise AI productivity tools.
