Kaspr vs Ocean.io: They Don't Do the Same Thing
If you're comparing Kaspr and Ocean.io, you probably expect two similar tools. They're not. Kaspr grabs phone numbers and emails from professional profiles. Ocean.io finds companies that look like your best customers. These tools solve different problems entirely - a distinction most buyers miss, and one that'll cost you months if you get it wrong. G2 doesn't even put them in the same category: Kaspr sits under Sales Intelligence, Ocean.io under Account Data Management.
30-Second Verdict
Kaspr wins if you need a Chrome extension that pulls verified contact details - especially European phone numbers - from professional profiles you're already browsing.
Ocean.io wins if your problem isn't finding contacts but finding companies. Its AI-powered lookalike search identifies accounts similar to your best customers.
Feature Comparison at a Glance
| Kaspr | Ocean.io | |
|---|---|---|
| Core use case | Contact capture | Account discovery |
| Database | 200M+ profiles | Not disclosed |
| G2 rating | 4.4/5 (833 reviews) | 3.1/5 (12 reviews) |
| Pricing model | Per-user/month | Credit-based (unlimited users) |
| Free tier | Yes (limited) | 14-day trial (card required) |
| Key integrations | HubSpot, Salesforce, Pipedrive | HubSpot, Pipedrive |
| Chrome extension | Yes | Yes |
That review gap tells a story. Kaspr has 70x more G2 reviews, and Ocean.io's vendor profile hasn't been active for over a year.
The Real Difference
Here's the thing: comparing Kaspr to Ocean.io is like comparing a fishing rod to a fish finder. Kaspr helps you catch the fish you've already spotted - you see a prospect on a professional profile, click the extension, and grab their phone number and email. Ocean.io helps you figure out which pond to fish in by using AI to find companies that resemble your existing customers.
This matters because buying the wrong one wastes months. If your SDRs already know who to call but can't find direct dials, Ocean.io won't help. If your team doesn't know which accounts to target, Kaspr's Chrome extension is irrelevant until you solve that upstream problem.
Most teams searching this comparison actually need both capabilities - account discovery and contact capture - but neither tool delivers both well. The smarter play is stacking a lightweight account-identification method with a dedicated contact data tool, rather than forcing one platform to do everything.
Kaspr - Who It's For
Kaspr's sweet spot is a small SDR team of one to five reps prospecting from professional profiles and needing European phone numbers fast. With 40,000+ users, the Chrome extension workflow is genuinely slick - click on a profile, get verified contact details, push them to your CRM. That's the whole pitch, and it works.
The 4.4/5 G2 rating from 833 reviews backs this up. Ease of use gets 14 mentions in review themes, accurate contact info gets 10, and the professional-profile integration gets 6. We've tested a lot of Chrome extensions for contact capture, and Kaspr's is one of the smoother experiences out there for European data specifically.
Use Kaspr if you prospect from professional profiles daily, need European direct dials, and your team is small enough that credit limits won't sting.
Skip Kaspr if you're running high-volume outbound. Credit limits are the #1 complaint across G2 reviews, and costs scale fast. The free plan gives you 5 phone credits and 15 B2B email credits per month - that's one afternoon of prospecting. Even the Business plan at $79/user/month on annual billing caps you at 200 phone credits per month. Data quality also drops noticeably outside Europe, so US and APAC teams should look elsewhere.
You shouldn't have to choose between finding the right accounts and finding accurate contact data. Prospeo gives you 300M+ profiles with 30+ filters - including buyer intent, technographics, and headcount growth - so you discover accounts AND capture 98% accurate emails and 125M+ verified mobiles in one platform.
Stop stacking two broken tools. Get both for $0.01/email.
Ocean.io - Who It's For
The concept behind Ocean.io is compelling: feed it your best customers, and its AI finds similar companies you haven't discovered yet. It pulls from 16+ data sources with waterfall enrichment, includes double email verification including catch-alls, and offers prospect segmentation for targeting. For teams whose bottleneck is account discovery rather than contact capture, that's genuinely useful.
The execution doesn't match the promise. Ocean.io's G2 rating sits at 3.1/5 from just 12 reviews, and the negative themes are brutal. Data inaccuracy shows up repeatedly - one reviewer titled their review "Stolen data sets and yet still fails at accuracy." Export limitations and pricing complaints round out the top issues. Reddit discussions on this comparison are thin; the few threads that exist mostly redirect people toward broader tools like Apollo.io.
Use Ocean.io if you genuinely need AI-powered lookalike account discovery, your problem is identifying the right companies rather than the right contacts, and you have budget for an annual commitment.
Skip Ocean.io if you care about data accuracy, need transparent pricing, or want a tool with a proven track record. Twelve G2 reviews and an inactive vendor profile aren't confidence-inspiring for a tool you're committing to annually.
Pricing Compared
Kaspr's pricing is straightforward. Ocean.io's takes some math - and patience. Their pricing page is genuinely confusing, mixing subscription, pay-as-you-go, and yearly toggles on the same screen.
| Free | Starter | Business | Enterprise | |
|---|---|---|---|---|
| Kaspr | $0 (15 B2B email + 5 phone credits/mo) | $49/user/mo (annual) | $79/user/mo (annual) | Custom |
| Ocean.io | 14-day trial (card req.) | ~$79/mo | ~$299/mo | $800-$2,000/mo |
Kaspr charges per user per month. Ocean.io runs on credits: $0.064/credit with a 9,000-credit minimum, verified emails cost 1 credit each, direct phone numbers cost 10 credits, and additional search results cost 0.2 credits each. Credits are valid for 12 months.
Let's break down the credit math with a real scenario. Say you need 500 verified emails and 50 phone numbers per month:
- Kaspr Starter: $49/mo on annual billing with unlimited B2B emails and 100 phone credits/month - this won't cover 50 phone numbers/month
- Ocean.io: 500 email credits + (50 phone numbers x 10 credits) = 1,000 credits/month in usage, but you're locked into a 9,000-credit minimum at $576 - so you're paying for credits whether you use them or not
- Prospeo: ~$10 at $0.01/email, with 75 free emails/month to start and no minimum purchase
The credit math looks favorable for Ocean.io on paper, but the annual commitment and overage risk change things fast.
Which One Should You Pick?
Pick Kaspr if your reps prospect from professional profiles daily, you need European phone numbers, and your team is small enough that credit limits won't bottleneck you.
Pick Ocean.io if your real problem is finding the right accounts, you need AI-powered lookalike company discovery, and you have budget for an annual commitment.
For teams that don't fit neatly into either camp - and honestly, that's most of the teams we talk to - the better approach is separating account discovery from contact capture entirely. Use whatever account discovery method fits your ICP process, whether that's Ocean.io, Clay list building, or manual research, then pipe those accounts into a dedicated contact data tool for enrichment and outreach. That's where the Kaspr vs Ocean.io debate becomes irrelevant: the contact layer matters more than either tool alone.
A Better Contact Data Layer
If neither tool fits, or you need the contact data layer regardless of which account discovery tool you use, Prospeo fills that gap. It covers 300M+ profiles with 98% email accuracy and 125M+ verified mobile numbers, all refreshed on a 7-day cycle - compared to the 4-6 week industry average. That's a different league from Ocean.io's accuracy complaints, and it solves Kaspr's credit limitation problem at roughly $0.01 per email.
The free tier gives you 75 emails per month plus 100 Chrome extension credits per month - no credit card, no contract. With 30+ search filters including buyer intent data across 15,000 topics, you can find and verify contacts without stitching together multiple tools. One of our customers, Snyk, cut their bounce rate from 35-40% to under 5% and saw AE-sourced pipeline jump 180% after switching.
If you're evaluating tools like this, it also helps to understand the broader landscape of data enrichment services and how they fit into your outbound stack.
Kaspr's credit limits choke at scale. Ocean.io locks you into 9,000-credit minimums with questionable accuracy. Prospeo starts free with 75 emails/month, charges $0.01/email after that, and refreshes every 7 days - not every 6 weeks. No annual contracts. No card required.
Get better data than both tools at 90% less cost.
FAQ
Does Ocean.io provide verified emails and phone numbers?
Yes, Ocean.io includes double email verification and direct phone number lookups, but they cost credits - 1 credit per verified email, 10 per direct phone number. Multiple G2 reviewers flag data inaccuracy as a recurring issue, so many teams pair it with a dedicated verification layer.
Is Kaspr only useful for European contacts?
Kaspr works globally, but data quality is strongest in Europe - that's where its 200M+ profile database is deepest. For US or APAC prospecting, accuracy drops noticeably. Teams focused outside Europe should consider tools with broader global coverage like Apollo.io or Prospeo.
What's the most accurate B2B email finder in 2026?
Prospeo delivers 98% email accuracy across 300M+ profiles with a 7-day data refresh cycle - the highest verified accuracy rate among self-serve platforms. It uses a proprietary 5-step verification process with catch-all handling, spam-trap removal, and honeypot filtering.
Is Kaspr or Ocean.io better for small teams?
Kaspr, without question. Its free plan lets you test the workflow immediately, the Chrome extension requires zero setup, and the per-user pricing is predictable. Ocean.io's credit minimums and annual commitment make it a poor fit for teams under 10 reps who are still figuring out their ICP.
