Kaspr is a LinkedIn Chrome extension that reveals phone numbers and email addresses directly on LinkedIn profiles. It is owned by Cognism and targets SDRs who need quick contact data without leaving LinkedIn. Pricing starts at $49/mo for 1,200 credits, with a free plan offering 5 phone and 5 email credits per month. For teams that need enrichment beyond one-off lookups — buying signals, waterfall data, and CRM automation — SyncGTM provides a more complete GTM platform.
You are probably here because you spend hours on LinkedIn and want a faster way to grab direct dials. Kaspr promises exactly that — one click on a profile, phone number appears.
The question is whether a Chrome extension that shows phone numbers is enough for a modern sales workflow. This Kaspr review covers accuracy, pricing, limitations, and whether your team has outgrown the extension model.
Kaspr Review: What You Get (and What You Don't)
Kaspr overlays contact data on LinkedIn profiles. When you visit a profile, the extension shows available phone numbers and email addresses. You can also run bulk extractions from LinkedIn Sales Navigator lists.
| Feature | What's Included | Limitations |
|---|---|---|
| Phone Numbers | Direct dials and mobile numbers from LinkedIn profiles | 50-65% accuracy; US numbers weaker than European |
| Email Finding | Business email addresses | Single data source; no waterfall verification |
| LinkedIn Integration | Chrome extension overlay on profiles and Sales Navigator | Depends on LinkedIn; subject to LinkedIn rate limits |
| CRM Integration | HubSpot and Salesforce on paid plans | No Pipedrive, Attio, or Zoho support |
| Buying Signals | Not available | No job change, funding, or intent signals |
Kaspr Chrome Extension: LinkedIn Phone Finding Tested
The Chrome extension is Kaspr's core product. Visit any LinkedIn profile and the extension shows phone numbers and emails in a sidebar overlay. The experience is smooth — data loads within 2-3 seconds on most profiles.
Bulk extraction from Sales Navigator lists is also available. Select a list of up to 2,500 profiles and Kaspr enriches them in the background. This is useful for building call lists from targeted searches.
Where it works well
For SDRs who prospect directly on LinkedIn, Kaspr reduces friction. No tab switching, no uploading CSVs, no waiting for batch jobs. You see a profile, you get the number. For phone-first outbound teams, this workflow is fast.
The limitation: LinkedIn dependency
Kaspr only works on LinkedIn. If your prospect is not on LinkedIn, or if their profile is minimal, Kaspr has no data to show. The tool also depends on LinkedIn's tolerance for browser extensions — LinkedIn periodically restricts automation tools, which can disrupt Kaspr's functionality.
Kaspr Data Quality: How Accurate Are the Phone Numbers?
Kaspr's phone number accuracy sits around 50-65%. European numbers are generally more accurate than US numbers, likely because Kaspr shares data infrastructure with parent company Cognism, which has stronger European coverage.
Email accuracy is better — around 75-80% for business emails. Personal emails are not provided.
The single-source problem applies here too. When Kaspr's database misses a number, there is no fallback. Waterfall enrichment tools check multiple providers and achieve 85-95% overall match rates. For phone numbers specifically, multi-source verification can push accuracy above 70%.
Kaspr Pricing Breakdown
Kaspr offers four plans with separate phone and email credit allocations:
- --Free: 5 phone credits + 5 email credits/month. Enough to test, not to work.
- --Starter ($49/mo): 1,200 credits, CRM integration, bulk enrichment.
- --Business ($79/mo): 2,400 credits, advanced analytics, team management.
- --Organization ($99/mo): 4,800 credits, API access, dedicated support.
Hidden costs
- Credits expire monthly: No rollover. Use them or lose them.
- Phone vs email split: Phone and email credits may be allocated separately, complicating budget planning.
- Sales Navigator required: Bulk extraction needs a LinkedIn Sales Navigator subscription ($99+/mo) on top of Kaspr.
What Are the Downsides of Using Kaspr?
The biggest downsides are moderate phone accuracy, LinkedIn dependency, no buying signals, and credit allocations that burn fast for active SDRs.
Phone accuracy is a coin flip
At 50-65% accuracy, roughly half your phone lookups return either wrong numbers or no number at all. For teams that rely on cold calling, this means wasted dials and lower connect rates.
LinkedIn is a single point of failure
If LinkedIn changes its policies, restricts extensions, or throttles your account, Kaspr stops working. Your prospecting workflow depends entirely on a third-party platform's tolerance.
No signal intelligence
Kaspr reveals contact data but provides zero context about timing. No job change alerts, no funding signals, no hiring indicators. You know who to call but not when they are ready to listen.
SyncGTM vs. Kaspr: Feature-by-Feature Comparison
Here is how SyncGTM compares to Kaspr:

Waterfall Enrichment

Multi-Signal Monitoring
Job changes, funding, hiring, tech stack — know when to call, not just who to call.
Bulk Automation
Auto-enrich thousands of contacts and push to CRM without manual batch work.
CRM on Every Plan
$99/mo includes HubSpot, Salesforce, Pipedrive, Attio, and Zoho sync.
Is Kaspr Worth It?
Kaspr is worth it for individual SDRs who prospect on LinkedIn daily and need instant access to phone numbers without leaving the browser. The Chrome extension is fast and the UX is clean.
Kaspr is not worth it for teams that need accurate phone data at scale, buying signals, or automated CRM workflows. The 50-65% phone accuracy, LinkedIn dependency, and lack of signal intelligence limit its value for growing sales teams.
The verdict: Kaspr is a quick phone lookup tool for LinkedIn power users. If your outbound motion depends on calling the right person at the right time, you need more than what Kaspr provides.
