Agent-led discovery and debugging for software
AI agents are becoming how software gets chosen. Developers ask Claude Code, Codex, Cursor and ChatGPT which tool to use, and more and more they let the agent pick and integrate it. If an agent doesn't recommend you, or loops trying to figure out how to use your product, it moves on to something else.
Lightsage gets companies ready for the agent economy: visible to agents, so they get recommended, and usable by agents, so integrations work the first time. We track how often coding agents and AI answer engines recommend a company against its competitors, run real coding agents against its APIs, CLIs and MCP servers to find where they fail, and tell the team exactly what to change.
We work with category leaders in AI and developer tools, including Firecrawl, Reducto, Scalekit, TinyFish, Daytona, Rime and Meetstream, and we run DevToolArena.com, a public benchmark that ranks developer tools by how well coding agents use them.
We've raised a $4M seed led by Nexus Venture Partners, and we're backed by growth leaders and founders of Postman, Apollo, Firecrawl, Resend, Daytona, TinyFish and others. Our goal is to be the default for any company that wants to win with agents.
As the Founding DevRel hire, you'll own how developers and developer-tool companies discover Lightsage. Working directly with the founders, you'll build our brand, community and developer relations from the ground up: shaping how we tell our story, growing DevToolArena.com, running events and launches, and owning the website and SEO. You'll decide where we show up, and measure what works.
Experience in growth, developer relations or developer marketing at a developer-tool, API or infrastructure company
Technical enough to build demos, read API docs and run coding agents yourself
Strong technical writing and a public portfolio (posts, talks, open-source work or videos)
Measures your work and runs experiments on content, channels and conversion
An existing network in the devtool or AI-agent community is a plus
Prior early-stage startup experience is a plus
This is a full-time, on-site role based in San Francisco, CA.
Lightsage helps software companies reach autonomous AI coding agents (like Claude Code, Codex, or GitHub Copilot) instead of only human developers. It provides an Agent-Led Growth platform that simulates real tasks for these agents using a company’s docs, APIs, SDKs and CLIs to diagnose why agents can’t discover, authenticate, or reach endpoints. The system then measures agent traffic andConversions, offering three areas: Agent Discovery (how agents find products), Agent Experience (how well agents can use them), and Agent Analytics (data about agent interactions). Lightsage also runs DevToolArena.com, a public leaderboard for agent tools. Its goal is to expand Agent-Led Growth infrastructure so B2B software makers can be found, used, and bought by autonomous AI agents, not just human developers.
