# 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_domain` column, or one domain per line) ## Inputs - `--domains-file=<path>` — CSV or txt with company domains (one per line, or a column named `company_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.
