LightSprint raises $6.1M to help PMs, designers and ops ship on their real codebase

LightSprint has raised a $6.1 million seed round led by 645 Ventures, with participation from multiple venture firms and angel investors, to expand its platform for enabling employees across a company to build software on production codebases using AI agents. The company argues that while early AI development tools made prototyping accessible to non-engineers, they did not eliminate the handoffs, rebuilding, and review challenges involved in deploying changes to complex real-world applications. LightSprint connects to existing, including multi-repository, codebases and allows team members to describe changes in plain language, collaborate on plans, view live previews, and generate code within environments configured and governed by engineering teams. Its platform includes cloud-based development, security safeguards, consolidated AI code-review feedback, and existing merge workflows, with the aim of allowing product, design, sales, marketing, and operations staff to contribute changes while engineers retain control over final reviews and merges. Founded in 2026 by Ben Ong, Benedict, and Heng Hong after their experience in AI products and engineering leadership, the Y Combinator Spring 2026 company says non-engineers have already shipped thousands of pull requests through its product and plans to use the funding to strengthen enterprise capabilities and grow its engineering and go-to-market teams.
