Can Claude Code and Codex actually use your API? (October Edition)

A real-world developer use case for every API, and their own isolated sandbox. This is the most comprehensive run we've ever done.

We just raised $4M at Lightsage, led by @nexusvp, to build the growth stack for internet’s newest customer: AI agents.

Claude Code, Codex, Cursor and other agents can already discover products, compare alternatives, read documentation, install SDKs, call APIs and start using software on behalf of humans. Soon, they’ll increasingly transact too and that changes how internet companies grow.

For decades, companies built growth infrastructure around humans. PLG helped humans adopt products. Now there’s a new journey to optimize: Can an AI agent discover you, choose you, successfully use you, and eventually pay for you?

We call this Agent-Led Growth.

Lightsage helps companies get discovered, recommended and used by agents
→ Agent Discovery - when and why agents recommend you vs. competitors
→ Agent Experience - whether agents can successfully use your APIs, SDKs, CLIs, MCP servers and agent skills
→ Agent Analytics - what real agents do when they reach your website, docs and product. and most recently agent-attributed traffic conversion.

Companies including @firecrawl, @reductoai, @daytonaio, @rimelabs, @Tiny_Fish and @insforge are already using Lightsage to build their agent-led growth strategy and improve their agent journey.

We’re incredibly grateful to have Nexus lead this round alongside these amazing founders and operators.
- Former Salesforce CTO Steven Tamm
- Postman CEO @a85
- Apollo CEO Matt Curl
- DocuSign President Robert Chatwani
- Former GitLab Head of Growth @HilaQu
- Resend CEO @zenorocha
- Firecrawl Co-founder @ericciarla
- Daytona CEO @ivanburazin
- Tinyfish CPO @shuhao_friday
- Former VP Marketing Adam Frankl
- Former Netreo CEO Jasmin Young (Sothis Labs)
and many more!

As agents increasingly discover, evaluate, use and pay for products on our behalf, we believe every company will need to understand and optimize for the agent channel.

That’s what we’re building Lightsage for.

Huge thank you our customers, early investors @AlchemistAcc and everyone who believed in us early.

Honoured to be featured in Forbes. forbes.com/sites/davidpro…

We’re just getting started.
