API

The shortest path to every deal, hire and intro.

Query your relationship graph from anything. Find warm paths to any company, pull scored relationships, surface job changes, and build it all into your own apps, agents and workflows - powered by your real relationship data.

Built for your workflow

However your team uses its network

Every team uses their network differently. We work directly with customers to design integrations and workflows that fit how you actually operate - and if you have a workflow in mind, we'll help you make it real.

Custom Claude skills

Build a skill that answers "who do we know at [company]?" right inside Claude, and acts on the answer.

Internal tools & bots

A Slack bot that surfaces warm paths on demand, or relationship data piped into your own apps and dashboards.

Your own automations

Trigger alerts and workflows on warm paths, new connections or job changes - however your stack works.
