Why Teams Choose LeadBooster

Your APIs. Your data. Your spreadsheet. We just make them work together.

① Your APIs. Their Price.

Connect Hunter, Apollo, OpenAI — or any HTTP API. You pay those providers directly at their actual published rates. We don't touch the money, we don't bundle it into credits, we don't mark it up. Ever.

② Flat Fee. Zero Credits.

Free during beta — $15 for life at launch. Run 100 rows or 100,000 — the price doesn't change. No per-row fees, no credit anxiety, no surprise bills. Just a flat, predictable number you can plan around.

③ It's Google Sheets.

No new platform to learn. No onboarding call to book. No specialist to hire. LeadBooster opens as a sidebar in any Google Sheet your team already uses. Your data never leaves your Google account.

$15 one-time at launch + Your API keys at provider cost

Complete lead enrichment stack. Predictable cost. Your data stays yours.

Already pay for Hunter, Apollo, OpenAI? Connect them directly — we never mark up their prices.

Already pay for these? Connect them directly at their actual price — zero markup

+ 20 more integrations — your keys, their price, nothing added

Everything You Need to Run Lead Enrichment.

Workflow builder, free scraping, AI research — all from inside Google Sheets.

Workflow Builder with Conditional Logic

Build your enrichment sequence once and reuse it on every campaign. Conditional logic skips rows that already have data — so you never pay to enrich the same lead twice.

  • Conditional logic per task (if email exists, skip)
  • Free tools run first, paid APIs only when needed
  • Reusable templates per campaign type
  • Cut API costs 40–60% by skipping unnecessary enrichments
FREE — No API key needed

Free Web Scraping

Scrape company websites at no extra cost. Extract emails, phones, and company data for every campaign — no credits, no per-page charges, no API key required.

  • Multi-page crawling with sitemap discovery
  • Email and phone extraction from company websites
  • Tech stack detection for lead qualification
  • Apify integration for protected sites (your keys)

Frequently asked questions

Who is LeadBooster for?

Cold email agencies, outbound freelancers, and founders doing their own outbound. If you already use Instantly, Smartlead, or HeyReach and want your enrichment to be just as streamlined — LeadBooster is built for you.

Are there really no credits?

None. Ever. Some tools charge per row enriched on top of their monthly fee — the more you use it, the more you pay. LeadBooster is free during beta and $15 for life at launch — regardless of how many rows you run.

What does "Bring Your Own API Keys" mean?

You connect your existing Hunter, Apollo, and OpenAI accounts directly. You pay those providers at their actual published rates. We never mark up their prices, never see your keys, and never bundle costs into credits.

What's included in the $15/mo?

Unlimited rows, free web scraping, AI research agent, workflow builder with conditional logic, and 20+ integrations. The only extras are the API providers you choose — and you pay them directly at cost.

How is this different from Clay?

Clay bundles data and charges credits per row — you pay their markup on top of a $149–349/mo platform fee. LeadBooster connects your existing API accounts and charges a flat $15/mo. Same enrichment sources, no middleman pricing, no credit system.

How is this different from n8n or Make?

n8n and Make are general automation platforms — you can build anything, but lead enrichment requires code and complex multi-node workflows. LeadBooster is built only for lead enrichment, so setup takes minutes, not days. No code. No 47-node workflows. Just click the APIs you want to run.

What can I scrape for free?

Regular company websites — email extraction, phone numbers, tech stack detection, sitemap crawling. For Cloudflare-protected or JavaScript-heavy sites, connect your own Apify key. Free scraping covers the large majority of B2B use cases.

Your APIs. Your Data. Your Spreadsheet.
All Working Together.

Connect any enrichment API to your lead lists in Google Sheets. No credits. No code. From $15/mo.
