How it works

From one sentence to a booked meeting

Finley does the research a great SDR would do for every single lead, then hands you emails worth sending.

Describe who you want

"Dental practices in Phoenix opening a second location." Plain English, as specific as you like.

Finley finds them

It searches the web, reads each company's own site, and finds the decision maker and an email they published.

Every lead gets scored

Fit, need, timing and reachability, each with a reason. Only good fits get an email.

You review and send

Researched emails land in your review queue. Approve, tweak or skip, then send from your own inbox.

Best-in-class emails

Emails that sound like you did your homework, because Finley did

Claude Opus 5.5 writes each email in one of 26 formats studied from cold emails that get replies, picked to fit what the research found. Then every draft has to pass checks before it reaches you.

  • Every claim traced to a source. If the research didn't find it, the email can't say it.
  • Short, plain and human. Length, reading level, subject line, links and spam phrases are all checked.
  • A second AI judges every draft. Anything under the bar gets rewritten, or flagged for you.
  • Written in your voice. Paste a few emails you've sent and Finley matches your tone.
Everything in one place

Find, score, write, send, measure

Lead finding from a sentence

No list to buy, no filters to fiddle with. Finley searches the live web, not a stale database.

Scoring you can read

Every score comes with its reasons, so you know why a lead is an A and another a D.

Researched personalization

Real facts from each company's own website, never generic first-line filler.

A review queue built for speed

Email, research and quality checks side by side. Approve and move on in one click.

Send from your own inbox

Gmail, Outlook or any SMTP. Daily caps, unsubscribe headers and a do-not-contact list built in.

Measure everything

Reply rate by email format and by lead score, cost per lead and per meeting, all from a full event log.

Pricing

Pay for the AI you use. That's it.

Most AI prospecting tools charge per seat and per credit. Finley runs on your own Anthropic key at list prices, so a few hundred leads costs a few dollars.

FAQ

Questions

Where do the leads come from?

Finley uses Claude's web search to find companies that match your description, then reads each company's own website for the right person and an email address they published. If you add a Hunter key, it can also look up work emails when a site lists none. It never guesses an address.

What does it cost?

Finley itself is free. You pay Anthropic for the AI it uses, at their list prices: well under a cent to find a lead and 1 to 2 cents to research, score and write its email. Claude Max and Team plans include monthly API credits that cover this.

Will the emails sound like a robot?

That's the thing we care about most. Each email follows a proven format, cites only facts Finley actually found, stays short, and passes a quality judge. You can paste your own past emails so it writes in your voice, and you approve every email before it sends.

Is it safe to connect my inbox?

Finley sends one email at a time from your own inbox, with a daily cap, a one-click unsubscribe header and an automatic do-not-contact list for bounces and unsubscribes. Your SMTP password is stored encrypted.

Can I run it myself?

Yes. Finley is open source under the AGPL. Clone it, run finley serve, and everything stays on your machine.
