You're paying to email companies that can't buy from you.

Aidenix scores every company on your list — size, stage, team, market — and tells you who to write and who to skip. Signals are great, but most of your list has none. Fit works even when a signal doesn't.

No card required

Problem & Solution

Outbound converts poorly because the list is wrong, not the copy.

Signals are scarce

Everyone sells buying signals, but most companies have none right now. No funding, no hiring, nothing. So who do you write then?

Personalization can't fix a bad-fit list

A perfect email to a company that will never buy is still a wasted send.

Aidenix profiles the company

Size, growth, team, stage, tech — so you know who's a real fit before you send, signal or not.

What you get

Everything you need to send only to companies likely to buy.

Company Fit Score

Each company scored on size, headcount dynamics, team makeup, stage, geo, B2B/B2C — plus tech and funding where the data exists.

Instant scoring

Who to write, who to skip

A clear cut on your list: good-fit companies to send, bad-fit ones to drop before they cost you a send.

Send or skip

Company profile & signals

The structured depth behind the score: what the company is, where it's going, and the context worth writing about.

Deep research

The message — or the data to write it

For companies worth writing, a first email drafted and ready. Or take the profile and signals and let your own writer (or agent) write it.

Draft or data

Scored from public and licensed company data — headcount, stage, tech, funding — not guesswork.

Deliverability

The address passed verification. The person left two years ago.

Fit tells you the company is worth writing. Liveness tells you the person is still there. Aidenix checks both, so you don't burn sends on dead contacts or bad-fit accounts.

Beyond syntax and SMTP

Person-level liveness, not just "the server replied."

Catches catch-all blindness

Where ordinary verifiers mark every address on a domain as valid.

Protects your sender reputation

Fewer bounces and dead sends per campaign, so your good emails keep landing.
