SignalHire

For SDRs and founders who need to go from a name to a direct dial or verified email without a lot of tooling overhead, SignalHire is a straightforward pick in the email and phone finder category. The API is available and capable enough that you can wrap it into your own automation layer or MCP-style orchestration — it won't fight you, though MCP-native support isn't confirmed yet. Pricing starts free and stays affordable for small teams, but the per-credit model means costs scale with volume, so mid-market teams running high-frequency prospecting should model that out before committing. The honest limitation here is depth of enrichment — SignalHire gives you contact data, but it doesn't layer in firmographic context, intent signals, or sequencing, so you'll need other tools alongside it for a full outbound stack.
