The Hidden Competitor: Fresh Google Maps Data

There's a third option many teams overlook: live Google Maps data with people enrichment.

Services like WebLeads search Google Maps for local businesses and enrich with verified contact data (owner names, emails, phone numbers). This approach offers:

• Fresh data: Every search returns current results, no stale database
• Local focus: Better for B2C-to-B2B outreach (agencies, local services)
• No subscriptions: Pay per enrichment, not per month
• Flexible: No minimum contracts
• Compliance: Data sourced directly from business listings

This works well if you're prospecting local service businesses (contractors, plumbers, HVAC), retail, or any geographically-targeted segment.

Final Verdict

• Best for small teams: Apollo ($49–$165/mo)
• Best for enterprise: ZoomInfo ($5,000+/mo)
• Best for local leads: Google Maps + enrichment services

For most small businesses and agencies, Apollo offers the best value. For enterprise sales teams with deep pockets, ZoomInfo's additional features justify the cost.

If you're prospecting local businesses, skip both and use fresh Google Maps data instead. It's cheaper, more current, and better suited to local outreach.
