| Lightsprint provides an AI-native product development platform that supports collaborative software development on a shared codebase. The platform offers a web-based workspace where product managers, designers, and engineers describe changes in plain English, review visual plans, and guide fleets of background coding agents. Its Visual Plan Modeturns requirements into structured task breakdowns, mockups, and codebase-aware specifications before any code is written. Parallel cloud agents then execute these plans in isolated environments, running tests and generating pull requests against existing repositories. Each change includes a live preview URL so non-technical teammates can review behavior before merge. Lightsprint is model- and tool-agnostic, integrates with systems such as GitHub, Linear, and Slack, and is designed to preserve institutional context about code patterns and product decisions over time. | $6.1M / Seed / Oct 13, 2026 | ||
