Lead enrichment platforms like Apollo, ZoomInfo, and Lusha charge hundreds of dollars per month—and that’s assuming you’re not burning through credits on every search. For solo operators and small agencies, those costs add up fast.
Today I rebuilt my entire prospect database using free lead generation tools—Google Places API, Hunter.io’s free tier, and some strategic manual searching. The result? 100 local businesses with 77% website coverage and 31% verified emails, all without spending a dime on expensive enrichment credits.
Here’s the exact stack I used and how you can replicate it.
The Problem With Traditional Lead Enrichment
Most B2B prospecting tools follow the same pricing model: pay per search, pay per export, pay per enrichment. It works fine at enterprise scale, but for a one-person SEO shop or small agency, you’re constantly watching credits drain while building prospect lists.
The real cost isn’t just the subscription—it’s the friction. When every API call costs money, you think twice before running that search. You end up with smaller lists, less experimentation, and slower growth.
What if the first layer of lead enrichment was essentially free?
The Free Lead Generation Stack
Here’s the stack I’m using in 2026. The key insight: Google gives away business data for free through the Places API. You just need to know how to tap it.
Layer 1: Google Places API (Free)
The Google Places API returns business names, addresses, phone numbers, categories, ratings, and sometimes websites—all from Google’s own database. The free tier gives you $200/month in credits, which translates to thousands of business lookups.
For local prospecting, this is gold. Search for “plumbers in Seattle” and you get every business Google knows about, complete with their phone number and (often) website.
What you get:
- Business name, address, phone
- Category (dentist, plumber, law firm, etc.)
- Website URL (when available)
- Rating and review count
- Business hours
Cost: Free for most use cases (the $200 monthly credit covers thousands of searches).
Layer 2: Hunter.io Free Tier (Find Business Emails)
Hunter.io is an email finder that searches domains for professional email addresses. The free tier gives you 50 searches per month—not unlimited, but enough for targeted prospecting.
The workflow: once Google Places gives you a website, Hunter.io searches that domain for emails. For a domain like “acmeplumbing.com,” it might return john@acmeplumbing.com, info@acmeplumbing.com, and billing@acmeplumbing.com along with confidence scores.
What you get:
- Email addresses found on the domain
- Name associations (when available)
- Confidence score
- Email verification status
Cost: 50 free searches/month. Paid plans start at $49/month for 500 searches.
Layer 3: Brave Search for Gap Filling
Not every business in Google Places has a website listed. Some local operators only have Facebook pages, or their website isn’t connected to their Google Business Profile.
For these gaps, a quick search on Brave Search (or any search engine) often reveals the website. Search for “Acme Plumbing Port Ludlow WA” and you’ll likely find their site in the results.
This step is manual but fast—maybe 30 seconds per business. For a list of 20-30 businesses without websites, it’s 15 minutes of work.
Layer 4: Notion as the Data Layer
All this data needs to live somewhere searchable and structured. I use Notion databases with properties for:
- Business name
- Category/industry
- Website
- Phone
- Email (best contact)
- Location
- Status (not contacted, pitched, client, etc.)
The Notion API lets you programmatically create and update entries, so the entire enrichment pipeline can be automated with a script.
Real Results: 100 Businesses in One Session
Here’s what I actually built today, prospecting local businesses in a small Washington state market:
- 100 businesses pulled from Google Places
- 77 with websites (77%)—after manual gap-filling with Brave Search
- 91 with phone numbers (91%)
- 31 with verified emails (31%)—from Hunter.io free tier
- Total cost: $0.002 (one DataForSEO API call for initial seed data)
The 23 businesses without websites? They’re truly local-only—contractors who work from referrals, a general store, a quarry. No online presence exists to find.
The Full Workflow
Here’s the step-by-step process, automated with an AI agent running through OpenClaw:
Step 1: Seed with Google Places
# Search for businesses by category and location
# Google Places returns name, address, phone, website, category
places_search("plumbers", "Port Ludlow, WA")Step 2: Enrich with Hunter.io
# For each business with a website, find emails
hunter_domain_search("acmeplumbing.com")
# Returns: john@acmeplumbing.com (confidence: 95%)Step 3: Fill Gaps with Search
# For businesses without websites, search manually
brave_search("Acme Plumbing Port Ludlow WA")
# Found: acmeplumbing.comStep 4: Store in Notion
# Create Notion entry with all enriched data
notion_create_page({
"Business": "Acme Plumbing",
"Website": "acmeplumbing.com",
"Email": "john@acmeplumbing.com",
"Phone": "(555) 123-4567",
"Category": "Plumber"
})Step 5: Push to Sales Tools
Once data is in Notion, you can export to whatever sales tools you use. I sync mine to Apollo (using their free accounts feature—no API credits needed) and Instantly for email campaigns.
Why This Beats Expensive Platforms
The traditional approach: pay $200+/month for an all-in-one platform, burn credits on every search, get locked into their ecosystem.
The free stack approach:
- Google Places: Free (up to $200/month in API credits)
- Hunter.io: Free tier (50 searches/month) or $49/month for more
- Brave Search: Free
- Notion: Free tier handles most use cases
Total cost for a solo operator: $0-49/month vs. $200-500/month for traditional platforms.
The trade-off is some manual work and scripting, but if you’re already running automation (or have an AI agent handle it), the manual overhead disappears.
The AI Agent Advantage
The real power of this stack comes when you automate it with an AI agent. My setup uses OpenClaw to:
- Run the Google Places search automatically
- Loop through results and call Hunter.io for each domain
- Search Brave for businesses without websites
- Create Notion entries with all data
- Push to Apollo/Instantly when ready
What would take hours of manual work happens in minutes, and the agent can run it overnight while I sleep.
Key Takeaways
- Google Places API is underrated for local lead generation—free tier covers thousands of lookups
- Hunter.io free tier (50 searches/month) is enough for targeted prospecting
- Manual search fills gaps fast—15 minutes for 30 businesses
- Notion as a data layer keeps everything organized and API-accessible
- AI agents turn this into autopilot—run the pipeline while you sleep
The era of paying $300/month for basic business contact data is ending. The tools are free—you just need to string them together.
