Argorant for Claude Cowork

Delegate lead-list building to Claude Cowork.

Cowork is built for handing off whole tasks, not single prompts. Connect Argorant over MCP and 'build me a list of 500 verified heads of operations at mid-size European logistics companies' becomes a task Cowork can actually finish — sized, deduplicated, verified, and delivered as an export link.

Setup

Connect Claude Cowork to Argorant

Cowork speaks the Model Context Protocol natively, so the connection is a one-time setup:

1

Create a free Argorant account — no credit card, 100 credits included.

2

In Claude Cowork, add a connector and point it at https://mcp.argorant.com/mcp.

3

Approve the OAuth prompt — the agent acts as your workspace, never as a shared account.

4

Delegate the task: describe the buyer, the geography, and how many contacts you need.

Lead generation with Claude Cowork

Hand Cowork the brief. Get back a finished, verified list.

Cowork shines when a task has real steps: resolve the industry, test a few segment definitions, compare counts, then commit credits to the best one. With Argorant's tool catalog it does all of that against 614M contacts — and because verification runs at export time, the list it hands back is checked the moment it's built, not whenever the database was last touched.

8,412 VP-of-Sales contacts at software companies in Germany.

Market sizing with Claude Cowork

Size a market before you spend a single credit.

Counting is free. Cowork can iterate through segment definitions — tighten the seniority, swap the geography, split by company size — and report exactly how many verified contacts each variant yields. You see the TAM math before any reveal happens, which is precisely the kind of multi-step diligence an agentic workspace is for.

Email verification with Claude Cowork

Every contact Cowork exports is verified at download time.

An agent that delivers bounced emails is worse than no agent. Argorant re-verifies addresses as the export is generated, so the file Cowork drops into your task thread reflects deliverability now. Bad addresses don't make the cut, and your sender reputation never pays for stale data.

CRM handoff from Claude Cowork

From delegated task to CSV, Smartlead, HubSpot, or Salesforce.

The last step of the task is the handoff. Cowork can finish by generating a time-boxed export link or pushing the segment toward your CRM and outreach stack — so 'build the list' and 'get it where the team works' are one delegation, not two tools and a copy-paste.

Testimonials

Revenue teams that stopped tolerating bounces.

We replaced ZoomInfo in a weekend. Same coverage, a fraction of the cost, and the emails actually land. Our bounce rate went from 28% to under 3%.
Maria Chen

Verification at export is the whole game. Every list we pull is checked live before it hits our sequencer — no more scrubbing through a second tool.
James Okafor
Founder · seed-stage developer-tools startup
We were paying $40K a year on an annual contract for data that bounced. Argorant is self-serve, a fraction of that spend, and the deliverability is night and day.
