A usable B2B lead is three jobs, not one: find the company and its contacts, enrich them with firmographics and domains, and verify the emails so you don’t torch your sender reputation. The big platforms (ZoomInfo, Apollo, Lusha) bundle all three behind an annual seat. This page maps the NexGenData actors that do each job on a pay-per-use basis — chain them and you have the core of an enterprise lead stack with no subscription.

Every actor runs on Apify, returns clean JSON, and bills per result. The honest caveat up front: public-source lead data has coverage limits and you must verify before you send — which is exactly why the pipeline below ends in verification.

The lead pipeline

1. Find — sources of companies & contacts

B2B Leads Finder — an Apollo alternative: find contacts by job title, company, and industry.
Company Email Finder — domain → discovered, pattern-validated business emails.
Contact Info Scraper — emails, phones, and socials from any set of sites.
Website Email Extractor — pull every email off a domain or page list.
Google Maps Scraper / Google Maps MCP — local-business leads with contact details and ratings.
Yellow Pages Scraper and Doctor Directory Lead Finder — vertical directories for niche prospecting.
Made-in-China B2B Suppliers — supplier sourcing leads.
Lead-Gen AI Agent — a natural-language interface that orchestrates lead discovery for you.

2. Enrich — turn a name or domain into a full record

Company Enrichment Tool — company → domain, firmographics, socials, employee band.
Lead List Enricher — CSV in → CSV out: emails, phones, and socials appended to your existing list.

3. Verify — protect deliverability before you send

Email Verification Tool — SMTP, MX, catch-all, disposable & role-account checks (a ZeroBounce/NeverBounce alternative).
Bulk Email Validator — CSV list hygiene at scale.
Email RBL Checker and DMARC Auditor — blocklist and domain-auth checks for sender health.

The end-to-end workflow

Stitch the three stages and you’ve rebuilt a ZoomInfo/Apollo workflow at pay-as-you-go cost: B2B Leads Finder or Google Maps Scraper to source → Company Enrichment Tool / Lead List Enricher to fill in domains and firmographics → Email Verification Tool to drop the risky addresses before your sequencer ever sees them. Run it on a schedule and you have a self-refreshing pipeline instead of a stale purchased list.

Why pay-per-use beats a seat

Seat-based tools (ZoomInfo, Apollo, Lusha) make sense if you prospect heavily every day. If you build lists in bursts — a campaign here, a territory there, an enrichment job once a month — you’re paying a year’s subscription to use the tool a few times. These actors bill per result with no minimum, run inside your own Apify account (API, SDK, Zapier/Make/n8n, or MCP for AI agents), and hand you the raw data to own.

Compliance, briefly

B2B outreach is legal in most places but governed (CAN-SPAM in the US, GDPR/PECR in the EU/UK): identify yourself, honor opt-outs, and confirm your lawful basis. Verified ≠ consented — this is prospecting infrastructure, not a license to spam.

FAQ

Is this a real ZoomInfo / Apollo alternative? For the core find-enrich-verify workflow, yes — assembled from pay-per-use actors instead of a seat. Coverage differs by source; you trade a fixed annual contract for metered cost and full data ownership.

How accurate are the emails? Discovery is pattern-based and strong for SMB/mid-market; always run the verification stage to drop catch-alls and dead mailboxes before sending.

Can I enrich a list I already have? Yes — the Lead List Enricher takes a CSV in and returns it enriched with emails, phones, and socials.

What does it cost? Pay-per-event on Apify — billed per lead/result, no subscription or per-seat fee.
