Kaspr vs LeadFuze: Head-to-Head Comparison for 2026
B2B contact data decays at roughly 2.1% per month. That means nearly a quarter of your database goes stale within a year - so your prospecting tool's data freshness matters just as much as its feature set. If you're rebuilding lists often, it helps to understand your broader lead generation workflow and where enrichment fits.

Here's the frustrating part of comparing Kaspr vs LeadFuze: one tool scales poorly the moment you start buying add-on phone credits, and the other can't seem to decide whether it's still selling self-serve software or pivoting to enterprise data licensing. We dug into both to figure out which one actually earns your money - and whether either deserves it.
30-Second Verdict
Pick Kaspr if you're an EU-focused SDR who lives in a Chrome extension and needs phone numbers for European prospects. If you're evaluating more tools in this category, start with our roundup of SDR tools.

Pick LeadFuze if you prospect exclusively in the US, want automated list building via Fuzebot, and don't mind committing annually to a product with mixed messaging around its own business model.
Pricing & Credit Breakdown
Kaspr
Kaspr is a Chrome extension that pulls contact data directly from professional profiles. It's fast, simple, and built for individual lookups rather than bulk list building. If you're comparing similar workflows, see our guide to email scraper Chrome extensions.
Pricing breaks down into four tiers. The Free plan includes 15 B2B email credits, 5 phone credits, and 5 direct email credits per month. Exports are capped at 10 per month on Free, so you can find data but hit walls moving it into your CRM or spreadsheets. Starter runs $49/user/month with 100 phone credits. Business is $79/user/month with 200 phone credits, 200 direct email credits, and API access upon request. Enterprise is custom with unlimited phone credits.
Here's where budgets blow up: add-on credits. Phone credit add-ons cost $0.21-$0.36 each depending on volume. We've reviewed dozens of credit-based tools, and this is consistently where the real cost hides. A team burning through 1,000 extra phone credits per month pays roughly $288 on top of their subscription - more than many competitors charge for unlimited access. Direct email add-ons start around $0.11-$0.16 per credit.
One more quirk worth knowing: your account needs at least 20 connections on the underlying professional network before Kaspr works, an anti-spam safeguard that trips up new accounts.
Pros:
- Fast, frictionless Chrome extension workflow
- Verified email indicators help you trust what you're exporting (and reduce email bounce rate surprises)
- Strong European phone number coverage
Cons:
- Credit limits feel restrictive; costs escalate fast with add-ons
- US and APAC coverage is noticeably thinner
- Export limits on lower tiers frustrate power users
Kaspr holds a 4.4/5 on G2 across 833 reviews. On Reddit, the recurring theme is credit burn for heavy dialers - reps who prospect aggressively can chew through phone credits in a week. If support responsiveness matters to your team, check recent G2 "Support" ratings before committing, especially on Starter.
LeadFuze
Let's be honest: LeadFuze's current state is confusing. They publicly market two different offers, and their own pages contradict each other. One official page announces they've shut down direct software access and now exclusively offer a full data license with monthly updates, priced at $1,500-$2,000/month depending on term. Another page still sells self-serve subscriptions at $397/month (Unlimited) and $497/month (Scaling). Verify which product you're actually buying before handing over your credit card.
The pricing mechanics matter. The "Unlimited" plan markets unlimited lead credits but requires an annual commitment. The "Scaling" plan caps you at 2,500 lead credits per month. LeadFuze says the only difference between plans is credits - feature parity across both. Credits roll over month to month as long as the account stays active, and there's a free trial available. Teams of 5+ users can request custom plans with custom lead credits and terms.
No API is available on any plan, per GetApp's product listing. If API access is a must-have, compare options in our guide to data enrichment services.
What the data license actually is. If you're looking at the $1,500-$2,000/month option, you're buying a literal dataset delivery: 269M+ profiles delivered as a 52GB CSV or 70GB Parquet file, with cloud delivery options and monthly refreshes. The tracking pixel isn't included. This is a fundamentally different product from the self-serve SaaS - think data warehouse enrichment, not daily prospecting.
LeadFuze's self-serve database covers 300M+ business professionals and 14M companies. Its standout feature is Fuzebot, an automation that continuously adds matching leads to your lists as new records enter the database. If you're building lists across multiple sources, our Clay list building breakdown can help you model the real cost.
The G2 rating sits at 4.6/5 with 119 reviews. G2 reports typical implementation under a month, with ROI realized around five months. The common gripe? Export size restrictions for large campaigns.
Pros:
- Fuzebot automates list building in the background
- Unlimited plan removes per-lead anxiety
- Credits roll over, reducing waste
Cons:
- International data outside the US is limited
- Multiple users report aggressive contract practices, including collections after cancellation attempts
- No API limits integration flexibility

Kaspr charges $0.21-$0.36 per phone credit. LeadFuze starts at $397/mo with no API. Prospeo gives you 125M+ verified mobiles with a 30% pickup rate, 98% email accuracy, and API access - starting at roughly $0.01 per email. No annual contracts. No credit traps.
Stop overpaying for credits that buy you stale data.
Data Coverage & Accuracy
| Category | Kaspr | LeadFuze | Winner |
|---|---|---|---|
| Database size | 120M+ contacts | 300M+ business professionals | LeadFuze |
| Starting price | $49/user/mo | $397/mo | Kaspr |
| Credit model | Per-seat credits | Flat (Unlimited) or 2,500/mo (Scaling) | LeadFuze (high volume) |
| Lead credits | 100-200 phone/mo | Unlimited or 2,500/mo | LeadFuze |
| API | Upon request (Business tier) | None | Kaspr |
| G2 rating | 4.4/5 (833 reviews) | 4.6/5 (119 reviews) | Kaspr (sample size) |
| Best region | EU | US | Depends on your market |
| Data refresh | Not disclosed publicly | Monthly (data license) | LeadFuze (if on license) |
| Compliance | GDPR-forward | Not stated on pricing pages | Kaspr |
| Key feature | Extension lookups | Fuzebot automation | Tied - different workflows |

The pricing structures couldn't be more different. Kaspr is cheap to start but expensive at scale. LeadFuze is expensive to start but cheaper per lead at high volume on the Unlimited plan. On the Scaling plan at 2,500 credits, you're paying roughly $0.20 per lead - comparable to Kaspr's add-on rates.
Look, if your average deal size sits below $5K, neither tool justifies its cost at scale. Kaspr's credit math punishes high-volume dialers, and LeadFuze's $397/month floor is steep for SMBs who need 200 leads a month. Both tools force you into a second data source for the regions they don't cover well. If you're pressure-testing ROI, benchmark against your average B2B lead conversion rate and CAC model.
Decision Shortcut
We've tested these tools across different team setups. Here's the fastest way to decide:

If you prospect by browsing profiles one at a time - Kaspr. The extension workflow is unmatched for individual lookups, especially in Europe.
If you want to set targeting criteria and let a bot build lists overnight - LeadFuze. Fuzebot is genuinely useful for US-focused teams who prefer passive list building.
For teams that need an API to plug into enrichment workflows or Clay/Zapier automations, neither tool works well. Kaspr's API requires Business tier and a request process. LeadFuze doesn't have one at all. If you're standardizing your stack, it may help to map this against your sales prospecting techniques and the systems you already run.
If you prospect across both the US and EU, you'll need something with broader coverage. Prospeo's database covers both regions in one workflow with 30+ search filters, intent data across 15,000 topics, and a 7-day data refresh cycle. The free tier gives you 75 verified emails and 100 Chrome extension credits per month to test without commitment.


Both Kaspr and LeadFuze leave regional gaps - one weak in the US, the other weak outside it. Prospeo covers 300M+ profiles globally on a 7-day refresh cycle, not monthly. That 2.1% monthly data decay the article mentions? Weekly refreshes cut your bounce risk before it compounds.
One platform, global coverage, data refreshed every 7 days.
FAQ
Is LeadFuze shutting down?
LeadFuze announced it shut down direct software access and pivoted to a full data license at $1,500-$2,000/month. That said, its self-serve pricing page remains live with active subscription options at $397-$497/month. The two offers coexist - confirm which product you're buying before committing budget.
Does Kaspr work outside Europe?
Kaspr's 120M+ contact database spans multiple regions, but its strength is European phone numbers. US and APAC coverage is noticeably thinner. If you prospect primarily outside the EU, pair it with a supplementary data source or switch to a tool with global coverage and a weekly data refresh cycle.
Which tool is cheaper per lead?
Kaspr Starter costs roughly $0.49 per included phone credit (100 credits for $49/month). LeadFuze Unlimited runs $397/month for unlimited credits - cheaper per lead at high volume, but a steep fixed cost for small teams. The Scaling plan at 2,500 credits works out to about $0.20 per lead. For email-first outreach, Prospeo averages roughly $0.01 per verified email, making it the most cost-efficient option when direct dials aren't your primary channel.
