Title, seniority, department, location, tech stack, funding stage, and headcount-growth deltas — the same filters your reps use in the app, exposed as JSON.

Deduplicated and verified across 14M companies. No stitching together three separate data vendors to get full coverage.

Cursor-based pagination, async bulk export to CSV or S3, and webhooks so fresh matches flow into your system automatically.

Proxy Bunlead search behind your own UI so your users build targeted lists without ever leaving your SaaS.

Give your ops team a custom sourcing dashboard backed by the graph — no seats in the web app required.

Generate target lists the moment a new segment matches your ICP and push them straight into your sequencer.
