Playbook
// fig. 02 — ai sdr playbook

Four moves in the AI SDR playbook.

Each row is one outbound move your agent runs against the same endpoint. Trigger, query, response, send — the data layer underneath stays constant.

// fig. 02move

Act on buying signals instantly

Wire job changes, funding rounds, hiring spikes and posted jobs into your agent. Trigger outreach the moment the signal fires.

Build prospect lists that update themselves

Define an ICP once with 60+ filters. Your agent re-queries on a schedule — new matches stream in, churned matches drop out.

Hit only fresh, employed prospects

Filter on is_currently_employed, verified_email and last_seen_at so your agent skips ex-employees and unverifiable contacts.

Personalize at the message level

Pull the prospect's current role, latest social post, recent funding and team size in one enrichment call. Hand the JSON to the agent for personalization.

Primitives
// fig. 06 — primitives

Three primitives behind every outbound call.

Find the ICP, hydrate the contact, react to the signal. The whole prospecting loop reduces to three primitives — pick how many your agent owns.

FAQ
// fig. 13 — ai sdr builders ask

Questions from AI SDR builders.

Anything we missed? Talk to us.

Job changes, role promotions, company funding rounds, headcount growth, new hires, posted jobs, social posts, tech stack changes and stealth founder transitions. You can subscribe to any subset and prioritize the ones that match your ICP.

Three transports: REST (JSON in, JSON out, Bearer auth), MCP (native tools for Claude, Cursor, OpenAI), and Webhooks (we POST deltas to your endpoint). Pick one or use them in combination — same dataset, three delivery methods.

We continuously crawl public sources and re-verify on demand. Watcher events fire within minutes of detection. For enrichment, you can request a real-time refresh that pulls live at the moment of the call rather than serving from cache.

Yes. We only ingest data from public sources, expose opt-out endpoints, ship a signed DPA and list our subprocessors. Bounce-prone or unverifiable contacts are filtered out before they reach your agent.
