What we do
Five categories of work. One team. One contract.
We fill your calendar with real buyers.
Researched outreach, warm follow-up, proposals the same day as the call. Claude does the reading; we do the judgment.
Read moreWe document your business while you run it.
Every meeting becomes action. Every process becomes a doc. Reporting stops being a Friday tax.
Read moreWe build what doesn't exist yet.
Custom CRMs, client dashboards, integrations between the tools you already pay for. Shipped with Claude Code.
Read moreWe make you visible where your buyers look.
LinkedIn, SEO, and now GEO — the new layer where AI decides who gets cited.
Read moreWe figure out what matters first.
An honest audit. A short plan. A founder who's been in your seat.
Read moreHow we work
Four steps, no theatre.
01Audit
We read your business — pipeline, ops, tools, presence. You get a short written plan within a week. You can take it and walk. Most don't.
02Automate
We set up the Claude-powered systems that do the reading, writing, and reporting. We absorb the API cost. You get one invoice.
03Operate
We run it. Outreach goes out, proposals get written, ops reports land on Friday. A human on our side reviews every message before it ships.
04Hand off (optional)
When you're ready, we train your team and hand over the keys. Not every client wants this. Some prefer we stay. Both are fine.

In their words
What clients say after they've worked with us.

Why Claude
The question isn't whether to use AI. It's which one, and who writes the glue.
Every agency will claim to “use AI” this year. Most mean a ChatGPT tab open next to Google Docs. We mean something different.
We build on Claude because it's the model that most reliably handles the long, messy, context-heavy work an agency actually does — reading a hundred-page brief, holding a week of conversation in mind, writing the same voice over and over without drifting. We use Sonnet for the ninety percent of work that wants fast turns, Opus when a proposal needs to sing, and cheaper models (Kimi, others) when the task is bulk and tolerant.
The API bill can be unpredictable. That's our problem, not yours.
You pay one fixed fee. We absorb the model cost and keep the discipline.
What we sell isn't Claude. What we sell is the glue — the process, the taste, the human on our side who presses send. A model can draft. Only a person can decide.
A note from the founder
I still take every first call. That's not a sales tactic — it's the whole idea.
I started Prospect Engine in 2020 as a cold-email shop. By 2024 we were writing more software than scripts. By 2026 it was clear the agency worth running is one where AI does the mechanical work and humans do the judgement work.
Ten clients at a time. I read every brief. I approve every proposal that goes out. When something breaks, you get me on Slack within the hour.
