THE FLOW

Four steps. One CSV.

01

Tell it who you sell to

Your offer, your ideal business customer, your geography. The skill walks you through the intake conversationally — not a form.

02

Pick the signals that matter

LinkedIn activity, employee count, recent funding, tech stack, hiring signals — or your own. You assign points; the skill scores accordingly.

03

It researches and builds

Web discovery finds companies and decision-makers. Every row researched. Every trigger verified before points are awarded.

04

You get a scored spreadsheet

HOT / WARM / COLD, sorted, ready to import. Score breakdown on every row so you know exactly why someone's high-priority.

WHAT YOU GET

A list you can actually work.

Every row is one person at one company. Company data repeated for each contact. No blanks, no guesses — verified or marked “Not found.”

  • Company name, website, industry, HQ, employee count
  • Decision-maker first/last name, role, LinkedIn URL
  • Email address where publicly findable
  • Prospect score + breakdown (LinkedIn:5 + Funding:4 = 9)
  • Trigger-specific columns for everything you chose
  • Includes the home-services ICP pack — pre-tuned scoring for HVAC, plumbing, roofing, and electrical

One row of an actual export. Yours will look like this — minus the example data.

BUILT FOR

Founders doing their own outreach.

I built this for the operator running their own prospecting at 11pm because the team is short-handed and the pipeline isn't going to fill itself. If you want quality over volume, your own scoring logic, and a CSV that's actually ready to import — this is the tool.

B2B only

Builds lists of businesses to sell to, not consumers. The skill refuses consumer-prospecting requests by design.

Web research only (free edition)

Discovery via web search. Real and useful, but email coverage is thinner. Pro edition adds verified executive emails at scale.

Runs locally in your Claude Code

No new account. No new SaaS dashboard between you and your list. Your prospect data is saved on your machine.

No signup gate

Free, downloadable, no email required. Newsletter is a separate, optional subscribe — your choice.
