Company Description

Lightsage builds infrastructure for the emerging agent economy, helping organizations track, benchmark, and improve how coding agents discover and use their APIs, CLIs, and MCP integrations. The platform is used by enterprises and high-growth startups to become the default tools recommended by software agents.

Lightsage focuses on agent experience and measurable impact on developer and product adoption, with more information available at lightsage.com. The team also created DevToolArena.com, a public benchmark that ranks developer tools across areas such as authentication, inference, and voice using Claude Code and Codex.

• Experience building or scaling a team, operating process, onboarding motion, or recurring customer workflow.
• Direct customer experience in requirements gathering, implementation, account ownership, or product feedback.
• Working knowledge of APIs, data integrations, analytics, data pipelines, and modern software delivery.
• Strong written communication and the ability to translate technical and customer requirements into clear product decisions.
• High ownership, dependable execution, and comfort operating in an early-stage startup.
