About

What is Kaspr

Kaspr sits as a Chrome extension on top of LinkedIn, Sales Navigator, and Recruiter Lite, surfacing verified phone numbers and email addresses for contacts in real time without leaving the browser. It's built for SDRs, BDRs, founders, and GTM engineers at SMBs and mid-market companies who need to move from a LinkedIn profile to a dialed number or sent email in as few steps as possible. The standout capability is automated enrichment workflows — you can set Kaspr to enrich entire lead lists and push the results directly into HubSpot, Salesforce, Pipedrive, or Lemlist without manual exports. Coverage skews toward European contact data, which is a genuine strength for EMEA-focused teams but a real gap if your ICP is primarily North American or APAC.

Our verdict

Vanderbuild take

Kaspr is a focused email and phone finder that earns its place in an outbound stack for SDRs, founders, and GTM engineers who live in LinkedIn and need contact data without a multi-tool detour. On the agentic readiness front, the REST API is available on the Business plan — solid enough that you can wrap it into your own MCP layer or automation pipeline when you need programmatic enrichment at scale. Pricing is freemium and affordable for small teams, but phone credit limits on the Starter tier are tight, and you'll feel the ceiling quickly if cold calling is your primary motion. The data coverage story is strongest in Europe; if your outbound targets are concentrated in North America, you may find hit rates inconsistent enough to warrant a second enrichment source alongside it.
