Why agencies switch

A separate data stack per client doesn't scale.

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.

The old stack
With Argorant
Sourcing per client
A different data login, scraper, or reseller for every account you run.
Sourcing per client
One source for every client. 614M contacts, any vertical, any geography.
List freshness
Reselling the same aging list to client after client until it bounces.
List freshness
Built live on every brief and re-verified at export — never a recycled file.
Client deliverability
One stale batch torches a client's sending domain — and your retention with it.
Client deliverability
Invalid is stripped before it ships, so every client's domain stays clean.
What you pay for
Stacked seat-based contracts you carry whether a client renews or churns.
What you pay for
Only the deliverable contacts you reveal. Counts and previews are free.
Onboarding a new account
Provision another tool, another seat, another invoice to reconcile.
Onboarding a new account
Spin up the next client's list in seconds — same workspace, same login.
The unfair advantage

Turn a client brief into a list — by typing it.

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.

  • “Ops leads at US logistics firms, 50–500 staff” — done.
  • Every contact verified before it reaches the client
  • Same engine in the app, CLI, REST API, and MCP

Verified before it ships

Every client list runs through live verification.

The moment you export, each address is checked against its mail server. Valid lands, risky is flagged, invalid never reaches your client's sequencer — so a bounce never lands on their domain or your invoice.

Any client, any territory, one source.

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 — no new vendor to onboard.

How agencies run it

From a client brief to a sending list in four steps.

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.

01

Describe the client's buyer

Paste the brief into Claude, ChatGPT, the CLI, or the app — “ops leads at US logistics firms, 50–500 staff.” Plain language, no filter syntax.
$ npx argorant search
  “ops lead, logistics, 50-500, united states”
02

Preview the match — free

See live counts and a masked preview before you spend a credit. Tighten it against the client's ICP until the list is exactly the brief.
03

Export, verified live

Reveal and export. Each address is SMTP-verified on the way out; only deliverable contacts are billed and delivered — so a client never gets a bouncing file.
04

Deliver to the client's stack

Download a CSV, pull over the REST API, or hand it to an AI agent via MCP — straight into the client's outbound, branded as your deliverable.
Every client domain stays clean

Protect the reputation you don't own.

You send from your clients' domains, but you carry the blame when one goes dark. Argorant strips invalid and risky addresses before they ever reach a campaign — so every client's deliverability holds, and a stale list never costs you a retainer.

  • Real-time SMTP checks at export, on every client list
  • Catch-all and risky addresses flagged, never billed
  • Identical verification across app, API, CLI, and MCP

It lands where your clients sell

Verified contacts, into any client's stack.

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.

You build the lists; what reaches your client is a verified, branded deliverable — a CSV, a CRM push, or leads already loaded into their sequencer. There's no Argorant tool a client has to log into, so the data layer stays your value-add and your margin.
Yes. Build a list against any client brief from the same login, save it, and keep each client's work organized as its own list. Switching from one account to the next takes a sentence, not a new contract or a new tool to provision.
Every address is checked against the receiving mail server at the moment you export, so invalid and risky contacts are filtered out before they ship. Your clients send from clean lists, their domain reputation stays intact, and a stale batch never costs you a retainer.
No per-client contract and no seat minimums. It's self-serve — counts and previews cost nothing, and you only spend on the deliverable contacts you reveal. Bill it back to the client as a line item or fold it into your fulfillment cost; the margin is yours.
Yes — export to CSV, pull over the REST API, fire webhooks, or connect an AI agent via MCP. Verified contacts drop straight into Smartlead, Instantly, HubSpot, Pipedrive, or anything you can reach with Zapier or Make.
Argorant is built for agencies running outbound on behalf of clients. You build verified lists against each client's brief and use them to fulfill that client's campaigns — and because lists are built live and re-verified at export, you're never handing a client a file that was scraped and left to rot.

Run every client from one verified source.

Build your first client list in under a minute. Free trial, no credit card.
