Reliable prospect data can make or break a revenue plan. If a seller can’t locate a direct dial or verify a buyer’s email, outreach stalls and pipeline slips.
Kaspr’s LinkedIn-centric plugin solves part of that problem, but its credit-based pricing and limited enrichment leave many teams wanting more, especially once they need fresh records outside LinkedIn or automated CRM hygiene.
This guide reviews 10 platforms that companies frequently shortlist when Kaspr no longer gets the job done. Relying on our combination of third-party reviews, unbiased rankings, and our own GTM Intelligence expertise, you’ll see how each tool approaches three core challenges:
Depth and freshness of global contact and company data
Workflow fit: integrations, list building, engagement, and compliance
Total cost for small businesses, mid-market teams, and enterprises
Whether you’re looking for a free entry point or an all-in-one outbound engine, these comparisons will help you weigh your options and choose a solution that keeps your go-to-market data accurate, actionable, and scalable.
What Counts as a Sales Intelligence Platform?
Sales intelligence tools collect, verify, and enrich company and contact data so go-to-market teams can:
Pinpoint decision-makers
Surface buying signals and intent
Automate data hygiene and CRM sync
Personalize multichannel outreach
Track performance with analytics dashboards
What Is Kaspr?
Kaspr is a sales intelligence add-on best known for its Chrome extension that uncovers phone numbers and verified email addresses while users browse LinkedIn. The tool enriches each contact with firmographic details, then lets reps export data to a CSV file or push it directly into a connected CRM or outreach platform.
Designed for quick prospect discovery rather than full-fledged engagement, Kaspr appeals to individual sellers and smaller teams that rely heavily on LinkedIn for lead generation. Users pay for a monthly credit allotment and spend those credits each time they reveal a contact’s information. The company positions this pay-as-you-go model as a lower-risk entry point for organizations that need occasional data rather than enterprise-wide licenses.

Because the product is geared toward small businesses and solo sellers, the interface focuses on speed: log in, locate a prospect, enrich a record, and move on. Real-time data updates ensure that phone numbers and email addresses stay current, while optional CRM connectors keep existing lists clean.
Key Capabilities

Teams that outgrow the free tier can upgrade to ZoomInfo’s paid editions, but many early-stage companies use ZoomInfo Lite as a long-term, zero-cost alternative to Kaspr for prospect discovery and basic data hygiene.
Choosing the Right Alternative
Match platform strengths to your biggest gaps:
Data depth and freshness: if global coverage and intent signals top your list, ZoomInfo Sales or Cognism may stand out.
Engagement tooling: teams wanting built-in sequencing often gravitate to Apollo.io or Waalaxy.
Budget and flexibility: UpLead and Seamless.AI emphasize lower entry costs and à-la-carte credits.
Evaluate integrations, compliance requirements, and contract terms before you decide. A short trial or pilot with live accounts usually reveals whether a provider’s data quality and workflow fit will drive the ROI your team expects.
