About

What is Swordfish

Swordfish AI searches across billions of data points to return direct dial phone numbers and verified business email addresses for sales and recruiting targets. It's built for SDRs, BDRs, founders, and GTM leads at mid-market and enterprise companies who need accurate contact data without managing credit budgets. The standout capability is real-time catch-all email validation combined with live data partner feeds — meaning the data is checked at the moment of lookup, not pulled from a static cache. A Chrome extension lets reps enrich LinkedIn and other profile pages inline, and bulk enrichment handles file uploads for larger list-building workflows. That said, Swordfish is a contact data tool, not a sequencing or outreach platform — once you have the numbers and emails, you'll need a separate tool to actually run campaigns.

Our verdict

Vanderbuild take

Swordfish AI is a focused contact data tool — it does one thing (find verified direct dials and emails) and does it without the credit-meter anxiety that makes other platforms frustrating for high-volume SDR and BDR teams. On the agentic side, the API is available on the Growth plan, but agentic readiness is limited — you can call it programmatically, but don't expect a clean MCP layer or agent-friendly orchestration hooks out of the box; you'll be building plumbing yourself. At $99/month for a solo seat and $299/month for teams, budget for an experienced operator — vanilla setup leaves value on the table, especially if you're trying to wire it into a broader GTM stack via Zapier or the API. The honest ceiling here is that Swordfish stops at contact discovery; there's no sequencing, no intent scoring beyond Bombora integration, and no analytics layer, so plan for it as one node in a larger workflow rather than a standalone outbound engine.

Agentic readiness

Limited

Usable but with caveats — rate limits, brittle endpoints.

API exists but is rate-limited, brittle, undocumented, or hidden behind enterprise plans. Use with caution in production agent workflows.

Stack role

Data source · Enricher

Where this tool slots into an agentic pipeline.

Plays the role of Data source + Enricher in an agentic pipeline. Use it to source contacts, companies, and the raw inputs an agent needs to act; add firmographic, technographic, and signal data to a lead row on the fly.
