Why teams switch

Outbound breaks at the data layer.

Stale lists, bounced sends, and locked-in contracts quietly cap every quarter. Here's what changes when the data is live.

The old stack
With Argorant
Finding the data
Buy a static list, or pay five figures for a seat-based contract.
Finding the data
Describe the buyer in plain English. 614M contacts, self-serve, no contract.
Building a list
An afternoon of filters, exports, and CSV cleanup.
Building a list
Ask in Claude, ChatGPT, the CLI, or the app — the list appears in seconds.
Verifying emails
Run a separate verifier, then hope the list didn't go stale.
Verifying emails
Every address is SMTP-checked the moment you export. Invalid never ships.
What you pay for
Per seat, per year — whether the contacts bounce or not.
What you pay for
Only the deliverable contacts you reveal. Counts and previews are free.
Tooling
Yet another dashboard for the team to learn.
Tooling
No new tool. If you can prompt an AI, you can build the list.
The unfair advantage

Stop filtering. Just describe your customer.

Every other data tool makes you translate a buyer into checkboxes. Argorant doesn't. Tell Claude or ChatGPT who you sell to, in your own words, and it builds, verifies, and hands back the list — inside the chat you're already in.

  • “Heads of growth at Series B fintechs in the UK” — done.
  • Every contact verified before it's returned
  • Same engine in the app, CLI, REST API, and MCP

Verified before it sends

Every 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 sequencer — so you never pay for a bounce.

How sales teams run it

From “who do we sell to?” to a sending list in four steps.

No filters to memorize, no export queue to babysit. Describe the buyer and go — the verification happens on the way out.

01

Describe your buyer

Tell Claude, ChatGPT, the CLI, or the app who you're after — “VP Sales at Series A SaaS in the US.” Plain language, no filter syntax.
$ npx argorant search
  “vp sales, series a saas, united states”
02

Preview the match — free

See live counts and a masked preview before you spend a credit. Tighten the targeting until the list is exactly the buyer you want.
03

Export, verified live

Reveal and export. Each address is SMTP-verified on the way out; only deliverable contacts are billed and delivered to you.
04

Push to your sequencer

Download a CSV, pull over the REST API, or hand it to an AI agent via MCP — straight into your outbound, where conversations start.
No more dead inboxes

Protect the domain your whole team sends from.

One rep blasting a stale list can flag the domain everyone sends from. Argorant strips invalid and risky addresses before they ever reach your tool — so every send counts and your reputation stays intact.

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

Every email is checked against the receiving mail server at the moment you export. Invalid and risky addresses are filtered out before delivery, so your bounce rate stays near zero and the domain your whole team sends from keeps its reputation.
Correct. You can build lists by prompting Claude or ChatGPT directly, from the command line, or in the web app. If you can describe your ideal customer in a sentence, you can build the list — there's no filter syntax or query language to memorize.
Down to role, seniority, department, industry and sub-industry, company size, revenue band, and location — from a single city to a whole continent. Preview the match and tighten it for free before you spend a credit.
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.
No contract and no seat minimums. It's self-serve with a free trial — counts and previews cost nothing, and you only spend on the deliverable contacts you reveal. Start with one list and scale when it works.
The index is continuously refreshed and re-verified, and verification happens live at export — so you're never sending to a contact that was scraped and left to rot six months ago.

Stop emailing dead inboxes.

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