What it does
Use the Blitz API to find decision-makers at specific companies when you already have a list of company domains. Best for SMB owner-finding, domain-to-people lookup, or supplementing Prospeo results. Outputs a CSV you can feed to the /list-builder Phase 5 or directly to /cold-email-starter-kit for Smartlead upload. Use when your targeting is company-first (not title-first).
Blitz List Builder
Prospeo is title-first: "all VPs of Marketing in B2B SaaS." Blitz is domain-first: "for each of these 500 restaurant domains, find the owner."
If you already know the target companies (from Google Maps, a CSV of competitors, or a manually-curated list), Blitz finds the people for you.
When to use Blitz vs Prospeo
| Your situation | Use |
|---|---|
| "I have 5,000 domains, find the owners" | Blitz |
| "Find all CFOs at US SaaS companies 100-500 employees" | Prospeo |
| "I need to supplement Prospeo results with additional contacts at the same companies" | Blitz |
| "I want the widest net possible in a vertical" | Prospeo |
| "I'm targeting specific named accounts (ABM)" | Blitz |
Often: use Prospeo to build the initial list, then Blitz to add 1-2 more contacts per company.
Prerequisites
- Blitz API key (env:
BLITZ_API_KEY), sign up at their website - List of target company domains (CSV with a
company_domaincolumn, or one domain per line)
Inputs
--domains-file=<path>, CSV or txt with company domains (one per line, or a column namedcompany_domain)--titles=<csv>, comma-separated title keywords to filter (default:owner,founder,ceo,president,cto,vp)--out=<path>, CSV output path
Outputs
CSV with columns: company_domain, first_name, last_name, job_title, linkedin_url, email, email_source, company_name, company_industry, company_headcount, company_phone
Email will be populated when Blitz returns one. Use /list-builder Phase 5 (scripts/contacts.ts) on the output to fill in missing emails, then validate with MillionVerifier (/cold-email-starter-kit).
