10 Best Seamless.AI Alternatives & Competitors (2025 Guide)
Let’s cut to the chase: Seamless.AI is solid, but it’s not the only player in the B2B contact data game. Whether you’re tired of its pricing quirks, limited integrations, or that pesky U.S.-centric focus, there’s a world of alternatives waiting to turbocharge your prospecting.
In this guide, we’re breaking down the top 10 competitors shaking up the scene in 2025. From budget-friendly picks to enterprise-grade beasts, we’ve got you covered. Oh, and we’ll toss in some cheeky commentary—because dry sales tools deserve a little spice.
🤔 Why Even Look Beyond Seamless.AI?
Seamless.AI’s AI-driven contact scraping is legit, but let’s face it: no tool is perfect. Here’s why teams are jumping ship:
- Price shock: Starting at $147/month? Ouch. Pro plans? Let’s not even go there.
- Integration FOMO: Only plays nice with HubSpot and Salesforce unless you’re shelling out big bucks.
- Keyword chaos: Can’t filter by keywords before revealing contacts? That’s like buying a mystery box.
- Euro snub: Good luck using it outside the U.S.—it’s basically a digital passport control.
- Compliance risks: Unlike GDPR-focused tools like Cognism, Seamless.AI’s terms restrict non-U.S. use and rely on customer-submitted data, raising privacy concerns.
Still here? Cool. Let’s dive into the alternatives.
