Ocean.io vs Wiza: Different Tools, Different Jobs - Here's How to Choose
Ocean.io and Wiza get compared a lot, but they're not really competitors. Ocean.io finds accounts through lookalike modeling. Wiza extracts contacts from professional profiles via a Chrome extension. Choosing between them is like choosing between a map and a phone book - they solve different problems entirely.
The real pain point is the gap between "finding the right companies" and "getting usable contact coverage." In outbound workflows, it's common to pull a strong company list and still miss contacts for a huge chunk of those accounts. That's the classic company-to-contact coverage problem, and neither tool alone solves both sides of it.
30-Second Verdict
Ocean.io is for ABM teams who need to discover net-new accounts that look like their best customers. Wiza is for SDRs who already know which companies to target and need verified emails and phone numbers fast. The G2 ratings tell a story: Wiza sits at 4.5/5 on 1,143 reviews, while Ocean.io lands at 3.1/5 on just 12 reviews.
Here's our take: if your average deal size is under $15k, you probably don't need Ocean.io's lookalike modeling at all. A solid contact data platform with intent filters will get you 90% of the way there at a fraction of the cost.

How Ocean.io Works
Ocean.io's core pitch is lookalike search. Feed it a reference company - your best customer - and it analyzes firmographics, technologies, and roles across millions of data points to surface similar accounts. For vertical sales teams selling into niche industries like maritime logistics or specialty manufacturing, that specificity genuinely beats filtering by SIC codes. We've seen teams in those verticals get real value from it when standard industry filters fall flat.
Here's the thing: the data quality underneath that clever discovery engine is shaky. G2 reviewers flag accuracy issues repeatedly, and export customization is limited. The discovery is smart, but what you actually pull out of it often needs a second pass.
Paid plans start at $59/month (annual billing) for Premium and $109/month (annual billing) for Professional, with custom pricing above that. Ocean.io uses a credit model where exporting a company or person costs 1 credit, showing a verified email costs 3 credits, and showing a mobile phone costs 10 credits. A 14-day free trial is available.
G2's most cross-shopped alternatives include Apollo.io, Cognism, and Lusha - which tells you where dissatisfied buyers end up.
Ocean.io finds accounts but struggles with contact accuracy. Wiza extracts contacts but charges $0.35/phone with no rollover. Prospeo gives you both - 300M+ profiles with 30+ filters for account discovery and 98% verified emails at $0.01 each, on a 7-day refresh cycle.
Replace two mediocre tools with one that actually delivers.
How Wiza Works
Nearly 500,000 individuals across 50,000+ companies use Wiza, and those numbers aren't accidental. The Chrome extension is genuinely fast: browse professional profiles, click extract, get verified emails and phone numbers. "Ease of use" appears in 427 G2 review mentions, and Wiza claims roughly 3x the contacts of leading database providers.
The complaints are just as consistent, though. 157 G2 reviewers call it expensive, and 127 flag limited credits. Credits don't roll over, overages hit at $0.15/email and $0.35/phone, and LATAM coverage is noticeably weaker than North America. If you're running outbound into Latin American markets, skip Wiza for that segment.
Pricing Compared
| Plan | Wiza | Ocean.io |
|---|---|---|
| Free | $0 (20 emails/mo) | 14-day trial |
| Starter | $49/user/mo | $59/mo (annual) |
| Mid-tier (email) | $99/user/mo | $109/mo (annual) |
| Full (email+phone) | $199/user/mo | Custom |
| Annual email | $83/user/mo ($990/yr) | Annual billing required |
| Annual email+phone | $166/user/mo ($1,990/yr) | Annual billing required |
Wiza's "unlimited" annual plans cap exports at 30,000/year - not truly unlimited. We've tested workflows where teams budgeting $99/mo ended up spending $180+ once phone number overages kicked in. That's frustrating, especially when the pricing page doesn't make the overage math obvious.
Ocean.io's costs are driven by credits: 1 credit per company/person export, 3 credits per verified email, and 10 credits per mobile phone. The math adds up fast if you're pulling both accounts and contacts.
Who Should Pick Which
Pick Ocean.io if you're an ABM team doing account-level targeting and your primary challenge is finding the right companies, not extracting contacts. It's a discovery tool first, a data tool second.
Pick Wiza if you're an SDR building contact lists from professional profiles and need a quick Chrome extension workflow. It shines when you already know your target accounts and just need the people inside them.
Let's be honest, though - neither tool alone covers both account discovery AND verified contact data at scale. You find the accounts but still can't reliably reach the right people, or you've got contacts but no systematic way to find new accounts worth targeting.
Prospeo bridges that gap with 300M+ profiles, 98% email accuracy, and 125M+ verified mobiles on a 7-day refresh cycle. Its 30+ search filters - including buyer intent tracking across 15,000 topics via Bombora - let you discover and contact prospects in one workflow, starting free. The consensus on r/sales threads is that consolidating your stack into fewer tools with better data beats juggling two mediocre ones every time.
The company-to-contact coverage gap costs teams deals every week. Prospeo closes it: 125M+ verified mobiles with a 30% pickup rate, buyer intent across 15,000 topics, and CRM enrichment returning 50+ data points per contact. One credit pool, one workflow.
Discover accounts and reach buyers in a single platform for $0.01/email.
FAQ
Can you use Ocean.io and Wiza together?
Yes - use Ocean.io to discover lookalike accounts, then Wiza to extract contacts. But you're paying for two tools with two credit systems and still dealing with accuracy gaps on both sides. For most outbound teams, a single platform that handles both discovery and contact extraction with one credit pool is a simpler, cheaper path.
Which tool has more accurate contact data?
Wiza is stronger on contact accuracy sentiment: 161 G2 mentions praise accuracy, even though 57 reviewers still flag inaccurate data. Ocean.io's reviews include recurring data quality complaints, so it's a riskier pick if your main goal is verified contact data rather than account discovery.
Is Ocean.io worth the price?
Only if lookalike account discovery is your primary need and you can't replicate it with intent-based or technographic filters elsewhere. The 3.1/5 G2 rating on just 12 reviews plus persistent accuracy complaints make it a tough sell if you're buying it mainly for data quality.
What's a good alternative to both tools?
Prospeo combines account discovery with verified contact extraction - 300M+ profiles, 98% email accuracy, 125M+ verified mobiles. At roughly $0.01 per lead, it replaces both tools for most outbound teams running under $20k deal sizes. Our team at Meritt saw pipeline triple from $100K to $300K/week after making the switch, with bounce rates dropping from 35% to under 4%.
