PerplexityEach client gets a list built live against its own brief and its own territory. Sizing a client's market costs nothing, so you can quote before you commit.
Juggling a login for every account, reselling lists until they bounce, and carrying contracts you can't cancel quietly caps how many clients you can run. Here's what changes when one verified source feeds every engagement.
Every client comes with a different ICP, and translating each one into checkboxes is where fulfillment time disappears. Paste the brief into Claude or ChatGPT in plain words and Argorant builds, verifies, and hands back the list — inside the chat you're already in.
You send from your clients' domains but carry the blame when one goes dark. Every address is checked against its mail server the moment you export, so invalid never reaches a client campaign, their domain, or your invoice.
184 countries, filterable down to the city. When a client expands or you sign one in a new market, pull a verified, on-territory list the same day, with no new vendor to onboard.
No filters to memorize, no export queue to babysit. Take the brief, describe it, and go — verification happens on the way out, before anything reaches your client.
A stale list never costs you a retainer, and an unreachable contact never costs you a credit. Bill it back as a line item or fold it into fulfillment; the margin is yours.
CSV, REST API, webhooks, or MCP — push each client's list straight into the sequencer and CRM they already run. No copy-paste, no broken imports, no per-client tool to set up.
