Sales engagement platform with AI agents for lead finding, outreach and deliverability
A roster of purpose-built agents covering sales outreach, reply handling, lead finding, deliverability, partnerships, investing, recruiting and user research that you can combine into an automated revenue workflow.
Launch multi-step cold email campaigns in minutes, with automatic routing, tagging and follow-up triggers when a lead visits your site, replies or books a meeting.
Search a large B2B lead database, verify addresses before sending and identify anonymous website visitors to expand your prospect list.
Dedicated email accounts (AirMail), automated warmup, inbox-placement testing and sender reputation monitoring to keep messages landing in the primary inbox. There is no AI-generated or role prose youll want to keep.
Agentic end-to-end testing that writes, runs and heals your test suite
Agents drive a real browser and live APIs like a user would, so a pass means the flow genuinely works end to end.
Each failure arrives with the failing step, screenshots, DOM snapshots, test source, root-cause hypothesis and a suggested fix.
Tests repair themselves when the UI drifts, and every passing test is kept so coverage grows with the app.
The same verifier runs from an open-source CLI, an MCP server in your IDE, a CI merge gate, or a no-code dashboard.
