Kaspr only works on LinkedIn.
Sendburg gives you more.
Kaspr is a LinkedIn Chrome extension that surfaces contact information when you visit LinkedIn profiles. Sendburg lets you search 150M+ B2B contacts directly — no LinkedIn profile visit required — with AI briefings and buying signals Kaspr doesn't offer.
Why teams choose Sendburg over Kaspr
Full database vs LinkedIn only
Sendburg is a searchable database of 150M+ contacts across all industries and geographies. Kaspr only surfaces contact data when you manually visit a LinkedIn profile — no bulk search or export.
Bulk export vs one-by-one
Sendburg exports thousands of contacts at once into your CRM or outreach tool. Kaspr reveals contacts one at a time as you browse LinkedIn, which doesn't scale for high-volume outbound.
AI briefings and buying signals
Sendburg includes AI-synthesized company briefings and real-time buying signals on all plans. Kaspr provides contact data only — no account intelligence layer.
