Your next customer is looking for you.
But you haven't shown up.
And nothing is fixing that.

The fastest way to find out who is interested in you is to know who isn't.

Stop paying to talk to people who don't care.

From the endless stream of "Lead Gen Specialists" to the costly ABM platforms, you are drowning in schemers and promises that are either empty or expensive. You don't need more lists or pipelines.

You need to cull and distill what you have.

I built a new kind of machine that takes your expensive, warm, 1,000-person lead list and proves there are 960 targets you should not waste your time talking to. Then it goes deep on who's left and analyzes them individually. It figures out what makes them tick and what they need to hear. Then it writes it all out for you: brochures, one-sheets, emails, direct messages. All the copy, for whatever channel you need. Your own B2B matchmaker.

Here is how it works.

seven stages you see · twelve the machine runs
First, it cuts the names that were never going to buy.01

Every name gets a verdict before a word gets written: right person, right seat, still at the company, worth a real effort. Three outcomes. Pass, kill, or up-to-you. When most of your list ends up on the kill list, that's the machine working, not failing.

For those who made the cut, the engine pulls everything the public web has on them.02

Not just job history and college degrees. Articles, papers, talks, podcasts, social posts, their old websites, 5, 10, 15 years back. All of it found by search that runs on meaning instead of keywords, and it catches the threads a trained human misses.

It knows which John Smith is yours.03

The internet is full of text that carries your prospect's name but isn't about them. Boswell's identity gate quarantines more than half of what comes in.

Two AIs profile them separately. A third maps how they think.04

One model maps how they talk: the vocabulary, the rhythm, the words they reach for, and the words they never use. A second model works out what they mean: what they value, what they distrust. The two never see each other's work. Then a third takes both reports and determines how this person frames a problem, which arguments land, and what matters to them.

Then a rival LLM tears it down.05

Every claim inspected. No source, no pass. It knows the specific ways AIs lie. It's like Internal Affairs, adversarial by design. Nothing in this pipeline grades its own homework.

If the data says no, they go.06

Even a finalist gets cut when their case falls apart. No sunk cost bias: the work already spent on them doesn't get a vote.

Only then does it write. Your voice, shaped to how they think.07

The copy, built to their mindset and written in your voice, modeled from your real writing, with a hard list of what you would never say. Emails, connection notes, one-sheets, brochures, whatever the channel needs.

the head-to-head

I tested the copy, going head-to-head with the best available AI.At first, we lost.Now we win, dominantly.

Same target, two tests. One gets a high-quality prompt. The other goes through the Boswell Engine. An impartial judge rules. We got beat in the first few rounds, then we got better, and better. We kept the logs, from bad to good to great, and anyone can take a look.

* both paths run on Anthropic Fable 5, apples to apples.

Frames risk as a duty to the people who trust her, not as a number. Reaches for stewardship language; never says "upside." Decides slowly, in writing, after she has argued the other side.

a piece it wrote · the email

"You have spent a career making sure other people's money outlives them. The one plan nobody wrote down is your own. I would like fifteen minutes to change that, and I will bring the argument in writing first."

the loop

I built Boswell to learn. Every time it runs, it learns.

Every verdict, every reply, every override you make is logged and fed back in. Every month the machine knows your market better than the month before, because it learns from you and from every name you run through it. And you break through, because you know what they need to hear.

That's the Boswell Engine. Your matchmaker.

the offer · free

Send me 25 names. I'll tell you which ones will waste your time and money.

Pick any 25 from your list. The latest ones or the ones you keep meaning to call. You choose. I run every batch myself. I will send back a verdict on every name: who to drop, who to try, and why.

It takes less than two minutes. You lose some uncertainty and get a list of names that deserve your time and effort. When you see this work, you will want to run your lists through the entire process and get exclusive, hyper-targeted content that no human could afford to write. This is how you finally show up for your customers.

how it works

One click opens a pre-written email. Attach your list in any shape, spreadsheet, CRM export, or names pasted in. Send it. I take it from there.

Questions you should be thinking about

What do you need from me?
Your list, in whatever shape it exists. Spreadsheet, CRM export, names pasted into an email. I clean it, structure it, and take it from there.
What does a run cost?
It depends on your list, and here's the honest math. Firms charge six to seven dollars a name to research a list, so a thousand names runs six to seven thousand dollars before anyone writes a word. This engine's first job is eliminating names, so most of that spend never exists. And the better your list, the more names earn the deep work, which means the bill rises only when the news is good.
Where does my data live?
On our servers. The research itself runs through business-grade AI and search services from Anthropic, Google, OpenAI, and Exa, under commercial terms that do not permit them to train on it. The fine print names them and says what we collect.
Does my data train anyone else's machine?
No. There is only one machine. Your data sits siloed inside it and improves your runs alone. End of story.
Who sends the outreach?
Your team. You get finished, ready-to-send copy for every channel. If you want a hand beyond the copy, that's a separate conversation, and I'm easy to find.
the man who built the machine

Atma Degeyndt has spent his life reading people from what they leave in the open: nine years of Sanskrit as a monk, faces as a trained profiler, customers as a marketer in New York, reading for founders who couldn't. The Boswell Engine is that life compiled into software, a machine that studies a stranger's public words the way a scholar studies scripture. Closely, completely, and without skipping the parts that don't fit the story.

The thinking lives at Vice & Variance, his newsletter on why startup marketing fails. The practice lives at atma.marketing. The arguments happen on LinkedIn.
