Founding Partner Program · For AI-native API companies
Your users keep asking AI agents to set up your API. The agents keep getting stuck.
When a developer asks Cursor, Claude Code, or Codex to wire up your API, the agent is fluent up until your signup wall — then it tells the user to open a browser and paste a key. Most don’t come back. Relay closes that loop, then sends you a monthly cohort report so you can see what the agent-onboarded segment of your users looks like.
$2,500 prepaid · 30-day sprint · day-30 cohort report · renewal at $2,500/mo, decided after the report.
What you get in 30 days
01 · Integration
We add a webhook into your signup flow plus a one-line SDK call inside your key-validation middleware. Your existing auth doesn’t change. Cursor, Claude Code, and Codex agents using the Relay loop can complete signup, verify email, receive a real key, and make an authenticated call without ever bouncing your user to a browser.
02 · Instrumentation
Each Relay-issued key emits a single event the first time it’s used for an authenticated, non-test, non-healthcheck request. We join that event back to the signup it came from and stamp activation timing precisely.
03 · Day-30 cohort report
On day 30 you receive a Markdown report covering agent-attributed signups, completed signups, key handoffs, first authenticated calls, 24-hour and 7-day activation rates, time-to-first-call distribution, and — if you supply a direct-signup baseline cohort — an apples-to-apples comparison against your normal funnel. Without that baseline the numbers exist in a vacuum, so we ask for it as part of the SOW.
Who this is for
Founder/CEOs at AI-native API startups roughly $1M–$5M ARR. Model routers, eval/observability, browser/search/data APIs, sandbox and devtool APIs, rerank and embedding services. If you sell API access to developers and your users are starting inside a coding agent, agents are already attempting to onboard for them — and stalling.
We are intentionally not the right fit for: enterprise-only sales, teams without public API docs, products without a developer pricing tier, or anything heavy on regulatory friction.
Honest scope
We don’t replace your auth. Clerk, Auth0, Supabase, your own — they all keep issuing the session. Relay only handles the agent-driven onboarding side door.
We don’t guarantee traffic. We close the loop; demand still has to come from your users asking their agents to use your API.
Cursor, Claude Code, and Codex are mentioned as examples of where agents originate. They are not partners and we don’t imply endorsement.
Activation = first successful authenticated API call from a Relay-issued key, within 24 hours of the genuine handoff. Test traffic, healthchecks, and docs/playground pings are excluded if your middleware filters them out before reporting.
Reserve a sprint
$2,500 prepaid covers integration + 30 days of operation + the day-30 cohort report. If the report shows a channel worth keeping, you renew at $2,500/month, month-to-month. If it doesn’t, don’t. We’re still figuring out who this works for, so we’d rather hear “not a fit” than carry a customer who isn’t getting value.
