Seamless

Seamless.AI sits squarely in the prospecting database and contact-finder category — it's a credible option for SDR and BDR teams that need verified emails and mobile numbers at scale, and RevOps leads who want enrichment piped directly into Salesforce or HubSpot without a middleware layer. The REST API is available, so you can wrap Seamless into your own agentic stack or MCP layer when you need programmatic contact search and enrichment — though MCP-native support hasn't been confirmed, so expect some integration work to get there. Budget-wise, this is enterprise-priced territory: the free tier gives you 50 lifetime credits to evaluate the data quality, but any serious team deployment will involve procurement conversations, and add-ons like buyer intent data and job change alerts carry separate costs that aren't reflected in the base plan pricing. The credit system also means high-volume prospecting teams can burn through allocations faster than expected, so model your usage carefully before committing to a tier.
