What it does

One job, done right.

Sales Navigator matches accounts by domain. A wrong domain quietly maps to the wrong company, or to nothing at all, and the whole list is poisoned. This skill is built around that single fact.

It reads whatever you give it (a paragraph, a list of names, an ICP doc, a market segment), pulls every targeting signal that's actually present, asks before guessing on anything load-bearing, runs real web research to find matching companies, and emits a strict two-column CSV (Account Name, Website URL) that uploads cleanly.

It will tell you when it can't find enough companies at acceptable confidence. A shorter accurate list beats a padded plausible one.

Try saying

Any of these will work.

Build me a Sales Nav account list of Series B fintechs in the US with 50 to 200 employees.
Top 100 mid-market SaaS companies on the East Coast. Skip the FAANGs.
Companies like Stripe and Plaid. About 50 of them.
Here's our ICP doc. Turn it into a CSV I can upload to Sales Nav.
How it works

Five steps. Honest at every one.

01

Read the input

Classifies what you gave it: a brief, a doc, a name list, an existing CSV. Asks for target size up front.

02

Anchor the criteria

Pulls every targeting signal actually present, anchored to a quote. Nothing gets filled in by default.

03

Flag the gaps

Splits criteria into direct, inferred, ask, and unresolvable. Stops to ask about anything load-bearing.

04

Discover with sources

Real web search across funding databases, industry directories, and "top X" lists. Every name traces back to evidence.

05

Resolve and verify

Domains pulled from each company's own site, stripped to bare apex. Low-confidence rows surfaced for your review before the CSV is written.

Why it doesn't lie to you

Built around the things that usually go wrong.

!

Never invents companies

If it can't find your target N at acceptable confidence, it delivers fewer rows and tells you why. No fabrication to hit a quota.

@

Domain accuracy is the contract

Pattern matching companyname.com is not verification. Anything below high confidence gets flagged so you can decide.

?

Asks before assuming

"Mid-market" can mean 200 to 2,000 or 500 to 5,000 depending on who's asking. The skill confirms the interpretation instead of picking one.

Exclusions are honored

Named competitors, parent companies, subsidiaries: if you said skip them, the CSV omits them before it gets written.

The output

A clean, two-column CSV.

Sales Navigator's uploader accepts a lot of optional fields. This skill emits the two that actually drive matching, and nothing else. Drop it into Sales Nav, hit upload, watch the match report.
