San Francisco-based Lightsprint, a Y Combinator-backed startup, has raised $6.1 million to help non-engineers make changes directly to a company’s existing codebase using AI agents.
Its software turns a plain English request into a reviewable pull request, a proposed code change that engineers inspect before merging it into production. This lets product managers, designers and operations staff get more directly involved in shipping software.

CEO and cofounder Benjamin Ong says the traditional process involves a long chain of handoffs, from requirements documents and feasibility checks to mockups and engineers rebuilding the feature in code.
That can take two to three months. Lightsprint positions itself against fragmented tools such as Lovable, Figma and coding assistants like Anthropic’s Claude, offering a one-stop shop that connects to a company’s code. Its agents write product requirements documents, generate code and create live previews, after which human engineers decide whether to merge the changes.
Ong, Benedict Chan and Heng Hong Lee founded the company earlier this year. It began working with early users in April and now serves over 100 companies.
It went through Y Combinator’s Spring 2026 batch, and 645 Ventures led the seed round alongside January Capital, Rebel Fund and angels including Opendoor CEO Kaz Nejatian.
The six-person team, split between San Francisco and Singapore, will use the funding to hire in sales, marketing, design and engineering.
