Kaspr vs LeadGenius: Chrome Extension vs Data Research Service
Your SDR manager just asked you to evaluate Kaspr vs LeadGenius, and everyone's treating it like a normal "tool A vs tool B" decision. It isn't. These products serve fundamentally different buyers, budgets, and workflows - and pretending otherwise wastes everyone's time.
Kaspr is a rep-level prospecting extension you can roll out today. LeadGenius is closer to a data operations partner you budget for and manage like a program.
30-Second Verdict
- Pick Kaspr if you're an SDR or small team doing profile-based prospecting in Europe and need a fast Chrome extension in the ~EUR45-EUR99/mo per-user range. (If you're comparing stacks, start with our list of SDR tools.)
- Pick LeadGenius if you're an enterprise team with a $20K+ annual budget that needs bespoke, human-researched datasets across niche verticals or emerging markets. This is closer to a data enrichment service than a rep tool.
- Skip both if you need self-serve access to a large, verified database that scales without credit anxiety or a five-figure contract. In that case, compare sales prospecting databases instead.
The Core Difference
Kaspr is self-serve: a Chrome extension and web app that pulls emails and phone numbers off professional profiles, then lets you export or enrich in bulk. It's built for speed and rep autonomy. Kaspr was acquired by Cognism on 28 April 2022, and the combined stack delivers nearly 30% more mobile coverage in key markets - worth knowing if mobile numbers are your whole game.
LeadGenius is a managed bespoke data service. Machine learning plus human researchers build custom datasets, enrichment, tagging, and monitoring. It's been around since 2011 with 400+ customers across 30-40 countries.
Kaspr - What You Get
Use Kaspr if your reps live in profile-based prospecting and need emails plus mobiles in seconds. Skip Kaspr if you're doing high-volume phone enrichment - credits become the bottleneck fast.
Here's the thing most people miss: do the credit math before you buy. A "full pull" (email + phone) costs 2-3 credits per contact. At 50 contacts/day, you're burning through monthly phone credits in a day or two on the Starter plan. That's not a minor inconvenience - it fundamentally changes the economics of the tool once your team scales past a handful of reps. If you're building lists at scale, it's worth reviewing a more structured lead generation workflow.
Pricing
Kaspr publishes pricing on their site, and it lines up with what shows across review platforms:
- Free: EUR0 (15 B2B email credits/mo + 5 phone credits/mo + 5 direct email credits/mo)
- Starter: EUR59/user/mo monthly, or EUR45/user/mo billed annually - unlimited B2B emails (fair use) + 100 phone credits/month
- Business: EUR99/user/mo monthly, or EUR79/user/mo billed annually - unlimited B2B emails (fair use) + 200 phone credits/month + 200 direct email credits/month
- Enterprise: Custom
"Unlimited B2B emails" on paid plans sounds generous. In practice, teams still feel the squeeze because phones and direct emails are what you burn through when you're serious about outbound. If deliverability is a priority, pair any finder with an email deliverability guide mindset.
What Users Say
Kaspr holds a 4.4/5 on G2 from 833 reviews - real volume. The consistent praise: easy, fast, fits the rep workflow. The consistent complaint: credits and cost at scale.
Reddit threads on r/LeadGeneration get blunt about it - pricing ramps hard for phone enrichment, and support can be slow when you're burning credits and need answers. We've seen this pattern across multiple tools that gate mobile numbers behind separate credit pools: the sticker price looks reasonable until you actually try to use the product the way your team needs to. If you're weighing other options, see our roundup of free lead generation tools.
Kaspr's phone credits run dry in days. LeadGenius needs a five-figure contract. Prospeo gives you 300M+ profiles, 125M+ verified mobiles, and 98% email accuracy - self-serve, starting free, at ~$0.01/email.
Stop rationing credits. Start prospecting without a ceiling.
LeadGenius - What You Get
Use LeadGenius if you need bespoke datasets - niche verticals, messy geos, weird firmographics, or "this list doesn't exist anywhere." Skip LeadGenius if you just need a self-serve database for daily prospecting.
One thing most comparison articles get wrong: LeadGenius isn't managed-only anymore. They now offer a fully self-serve API experience with trial signup, keys, docs, and webhooks. Most customers still buy managed campaigns, but the self-serve door is open.
Pricing
LeadGenius switched from credits to "transparent, cents-per-record campaign pricing." The frustrating part: they explain the model but don't publish the rate card. In practice, expect $0.10-$2.00 per record depending on fields, verification depth, and geography.
Budget-wise, LeadGenius typically lands in these bands:
- Entry: ~$18K-$22K/year
- Pro: ~$50K-$80K/year
- Enterprise: $120K+/year
That's not "expensive" if the dataset is strategic. It's just not the same category as a EUR59/user tool. If you're running this as a program, it helps to align on firmographic filters up front.
What Users Say
LeadGenius sits at 4.3/5 on G2 with 14 reviews - small sample, but the themes are consistent. People like the human element and tailored support. They dislike when leads arrive outdated or off-target. G2's benchmarks show implementation under 1 month and ROI around 3 months, which tracks when teams treat it like a real data project rather than a quick-fix purchase.
Head-to-Head Comparison
Let's be honest: most teams searching this comparison don't actually need either one. Kaspr's credit model creates a ceiling you'll hit once outbound volume gets serious, and LeadGenius requires a budget and operational maturity that most sub-100-person companies don't have. The real question is whether you need a rep tool, a data program, or a self-serve platform that scales without either constraint.
Neither of these is a clean "ZoomInfo replacement." ZoomInfo is a broad GTM data platform with typical entry pricing around ~$14,995/year, and mid-market contracts run far higher depending on seats and modules. For context, Apollo sits at $49-$119/user/mo. Different weight classes entirely. If you're modernizing outbound, review these sales prospecting techniques before you swap tools.

Winner by row: Kaspr takes pricing entry, database size, self-serve access, and G2 rating. LeadGenius wins on data model flexibility and best-for scope. For off-the-shelf prospecting, Kaspr wins. For genuinely custom data needs, LeadGenius wins.
Who Should Pick Which
For SMB teams doing profile-led prospecting in Europe, Kaspr is the practical choice. Just go in eyes-open: teams hit the ceiling fast when leadership asks for more accounts, more contacts, more phones - and suddenly everyone's rationing credits like it's wartime.
For enterprise teams that need bespoke datasets in emerging markets or niche verticals, LeadGenius is the better fit. The $20K+ budget requirement is real. You're buying a process and a research engine, not a login. If you're selling into larger orgs, this aligns with how enterprise B2B sales actually runs.
For everyone in between, there's a third option that avoids both the credit squeeze and the five-figure contract. Prospeo gives you 300M+ profiles, 143M+ verified emails at 98% accuracy, 125M+ verified mobiles, and a 7-day data refresh cycle - all self-serve with no annual contracts. Pricing starts free with 75 emails/month, then works out to roughly $0.01/email. In our experience, it's the middle ground most teams actually want for day-to-day outbound. If you're also validating addresses, compare Bouncer alternatives.
Neither Kaspr nor LeadGenius refreshes data weekly. Prospeo runs a 7-day refresh cycle - 6x faster than the industry average - so your reps never email dead addresses or dial disconnected numbers.
Fresh data, no contracts, no credit anxiety. See the difference yourself.
FAQ
What's the main pricing difference between Kaspr and LeadGenius?
Kaspr charges per user per month with credits for phone and direct email lookups - starting at EUR59/user/mo monthly (EUR45/user/mo billed annually). LeadGenius charges per record on a campaign basis, typically starting around $18K-$22K/year. They're fundamentally different pricing models for fundamentally different use cases.
Is LeadGenius self-serve or managed-only?
Both. LeadGenius now offers a self-serve API with trial signup and webhooks, plus managed campaigns for bespoke datasets. Most customers still use the managed model, but the "no self-serve" narrative is outdated as of 2026.
Why are Kaspr credits so expensive at scale?
Kaspr charges separately for different data types, so pulling email plus phone for one contact costs 2-3 credits. High-volume prospecting teams burn through monthly phone credits fast, which makes the effective cost per usable contact climb quickly.
What's a good alternative if neither Kaspr nor LeadGenius fits?
Prospeo covers the middle ground - 300M+ profiles, 98% verified email accuracy, and 125M+ mobiles on a 7-day refresh cycle. It starts free (75 emails/month) with no annual contracts, making it practical for teams that outgrow Kaspr's credits but don't need LeadGenius-level budgets.
