Best for SMB owner-finding, domain-to-people lookup, or supplementing Prospeo results. Outputs a CSV you can feed to the email-waterfall or directly to /cold-email-starter-kit for Smartlead upload. Use when your targeting is company-first (not title-first).\n---\n\n# Blitz List Builder\n\nProspeo is title-first: \"all VPs of Marketing in B2B SaaS.\" Blitz is domain-first: \"for each of these 500 restaurant domains, find the owner.\"\n\nIf you already know the target companies (from Google Maps, a CSV of competitors, or a manually-curated list), Blitz finds the people for you.\n\n## When to use Blitz vs Prospeo\n\n| Your situation | Use |\n|---|---|\n| \"I have 5,000 domains, find the owners\" | Blitz |\n| \"Find all CFOs at US SaaS companies 100-500 employees\" | Prospeo |\n| \"I need to supplement Prospeo results with additional contacts at the same companies\" | Blitz |\n| \"I want the widest net possible in a vertical\" | Prospeo |\n| \"I'm targeting specific named accounts (ABM)\" | Blitz |\n\nOften: use Prospeo to build the initial list, then Blitz to add 1-2 more contacts per company.\n\n## Prerequisites\n\n- Blitz API key (env: `BLITZ_API_KEY`) — sign up at their website\n- List of target company domains (CSV with a `company_domain` column, or one domain per line)\n\n## Inputs\n\n- `--domains-file=<path>` — CSV or txt with company domains (one per line, or a column named `company_domain`)\n- `--titles=<csv>` — comma-separated title keywords to filter (default: `owner,founder,ceo,president,cto,vp`)\n- `--out=<path>` — CSV output path\n\n## Outputs\n\nCSV with columns: `company_domain, first_name, last_name, job_title, linkedin_url, email, email_source, company_name, company_industry, company_headcount, company_phone`\n\nEmail will be populated when Blitz returns one. Use `/email-waterfall` skill on the output to fill in missing emails via Prospeo/ZenRows/etc.\n\n## Usage\n\n```bash\nexport BLITZ_API_KEY=xxx\n\n# Pull owner/founder/CEO contacts for 5000 SMB domains\nnpx tsx scripts/find-contacts.ts \\\n  --domains-file=restaurants.csv \\\n  --titles=owner,founder,ceo,general-manager \\\n  --out=restaurant-owners.csv\n\n# Domain-first discovery with custom title match\nnpx tsx scripts/find-contacts.ts \\\n  --domains-file=saas-companies.txt \\\n  --titles=vp-marketing,head-of-growth,cmo,director-marketing \\\n  --out=saas-marketers.csv\n```\n\n## API overview\n\nBlitz has two main endpoints we use:\n\n**Company enrichment** (find employees):\n```\nPOST {BLITZ_BASE_URL}/api/enrichment/company\nBody: { \"domain\": \"acme.com\" }\nResponse: { employees: [{ first_name, last_name, title, linkedin_url, email }], company: { name, industry, headcount, phone } }\n```\n\n**Email enrichment** (find email for a LinkedIn URL):\n```\nPOST {BLITZ_BASE_URL}/api/enrichment/email\nBody: { \"linkedin_profile_url\": \"https://linkedin.com/in/...\" }\nResponse: { email: \"...\", status: \"verified\" }\n```\n\n## Rate limiting\n\nThe script throttles at **30 requests/second with concurrency 10**. This matches Blitz's published limits. If you see 429s, lower the concurrency flag.\n\n## Hit rate expectations\n\nRough benchmarks (from real campaigns):\n- **SMBs (restaurants, clinics, salons):** 70-80% contact-found rate, 40-60% email-found\n- **B2B tech (10-500 employees):** 80-90% contact-found, 50-70% email-found\n- **Enterprise (>1000 employees):** 90%+ contact-found, but filtering for the RIGHT person matters more than the found-rate\n- **Solo operators / micro-businesses:** 30-50% — often no public LinkedIn\n\n## Title filtering — write specific keywords\n\nDefault keywords (`owner, founder, ceo, president, cto, vp`) are broad. Narrow them per campaign:\n\n```bash\n# Restaurants\n--titles=owner,operator,general-manager\n\n# SaaS RevOps\n--titles=revops,revenue-operations,vp-sales,director-sales\n\n# Dental practices\n--titles=dentist,owner,practice-manager\n\n# Law firms\n--titles=partner,managing-partner,principal\n```\n\nThe script does case-insensitive substring match. \"vp\" matches \"VP Sales\" but also \"VP Product\" — narrow further if that's too loose.\n\n## Common gotchas\n\n- **Domain must be just the bare domain.** Blitz wants `acme.com`, not `https://acme.com/` or `sub.acme.com`.\n- **Huge companies return truncated employee lists.** Blitz caps at ~50-100 employees per domain. For enterprise-heavy lists, use Prospeo or LinkedIn search instead.\n- **Stale LinkedIn data.** Blitz's cache can be 3-12 months old. Job titles may have changed. Validate with the email waterfall.\n- **No email returned ≠ person unreachable.** 40% of hits have no email. Feed them to `/email-waterfall` — it'll try Prospeo + ZenRows.\n- **Rate-limit errors.** 429 = you hit the cap. Script retries with exponential backoff, but long bursts still fail.\n\n## Required step: Qualify with /icp-prompt-builder\n\n**This is a required step. Do not skip it.**\n\nBefore pulling more than 500 companies' worth of contacts, sample ~50 and run `/icp-prompt-builder` on them:\n\n1. Evaluates the first 10 with an AI qualification prompt\n2. You give corrections (\"this one should be NO because they're a competitor\")\n3. Refines the prompt, runs next 10\n4. Stops after 2 rounds with zero corrections — prompt is tuned\n5. Apply the tuned prompt to the remaining leads to filter before paying for email enrichment\n\n**Why it's required:** Blitz contact-finding is cheap, but email enrichment downstream is not. A typical 5,000-contact run costs $150+ in email-finding API calls. If 40% of your list is wrong-fit, you burn ~$60 finding emails at companies that will never convert. The ICP prompt builder takes 10-15 min and saves that.\n\n**How to skip safely:** you can't. If you're sure your list is already perfectly qualified (e.g., it came from a curated seed list of named accounts you want to pitch), run `/icp-prompt-builder` anyway on 10 of them and confirm your existing qualification matches — the prompt builder becomes a sanity check instead of a filter.\n\n## Cost\n\nPer Blitz pricing (check their current rates):\n- Company enrichment: ~$0.02-0.05 per domain\n- Email enrichment: ~$0.05-0.10 per email\n\n5,000 domains = ~$150 for contacts alone. Plan your budget.\n\n## Output → next step\n\nOnce you have the CSV, the typical flow:\n\n1. **Deduplicate** — remove duplicate emails, duplicate LinkedIn URLs\n2. **Filter** — drop rows where `job_title` doesn't cleanly match your ICP\n3. **Fill missing emails** — run `/email-waterfall` on rows with empty `email`\n4. **Validate** — run MillionVerifier on all emails (see `/email-waterfall` script)\n5. **Upload** — pass to Smartlead via `/cold-email-starter-kit` script `smartlead-add-leads.ts`\n\n## Scripts\n\n- `scripts/find-contacts.ts` — main batch enrichment script\n\n## What to do next\n\n**Run `/email-waterfall`** to fill in emails for rows Blitz didn't return. Then `/list-quality-scorecard` to grade the final list.\n\nAfter the scorecard, proceed to `/campaign-copywriting` → `/smartlead-campaign-upload-public`.\n\n**Or wait:** if the required `/icp-prompt-builder` step (above) showed <40% qualification rate, your source list of domains is off. Fix that before spending more Blitz credits.\n\n## Related skills\n\n- `/icp-prompt-builder` — qualify the contacts this skill returns BEFORE running email waterfall\n- `/prospeo-full-export` — the title-first alternative\n- `/google-maps-list-builder` — for local-business domain lists\n- `/disco-like` — lookalike companies from seed domains\n- `/email-waterfall` — when Blitz doesn't return an email\n- `/cold-email-starter-kit` → `06-list-building-prospeo.md` for broader list-building context\n","tagline":"Use the Blitz API to find decision-makers at specific companies when you already have a list of company domains.
