What is Improver
Improver extracts personal email addresses from LinkedIn profiles and social networks, aggregating contact details from publicly available sources and running them through a double-verification step before delivery. It's built for SDRs, BDRs, and founders who need to move from a LinkedIn profile to a working email address without manual digging. The standout capability is bulk contact search — you can run a list of LinkedIn profiles through at once and export the enriched results directly into a cold outreach campaign or CRM. A public API is available for teams that want to pipe data into their own workflows. The credit-based model means volume is capped by tier, so teams running high-frequency outbound at scale will hit ceiling limits quickly and need to weigh per-credit costs carefully.

Our verdict
Vanderbuild take
For SDRs, BDRs, and early-stage founders who need personal emails off LinkedIn without paying Apollo-tier prices, Improver is a focused, no-frills option in the email finder and data enrichment space. The API exists, but agentic readiness is limited — you can call it programmatically, but don't expect to build a reliable autonomous enrichment pipeline on top of it without hitting friction in rate limits or endpoint stability. Free to start and $15/month at the entry paid tier, so the risk to test is low. The honest constraint is volume: the credit model means this works well for targeted, deliberate prospecting but gets expensive or restrictive fast if you're running bulk enrichment at any real scale.
