Ocean.io
B2B prospecting tool that finds "lookalike" companies and contacts similar to your best customers.
RecommendedLast reviewed July 17, 2026
What Ocean.io actually is.
Ocean.io starts from a company you already sell to, not a keyword. Give it a domain and it returns similar companies, pulled from an index of 67 million company profiles and 250 million+ employee records. You can also describe an ideal customer in plain language instead. Either way, the output is an account list, plus some contacts, that you push into a CRM or an enrichment tool.
The matching is only as good as the example you feed it. Feed it a vague or mixed closed-won list and the lookalikes come back vague too, with no manual filter to fix that after the fact. It's credit-based rather than seat-based, and the platform, API, and Clay connections draw from the same pool.
What it does
- Finds companies that resemble a customer you name.
- Also searches by plain-language description of your ideal buyer.
- Pulls from 67 million company profiles and 250 million+ employee records.
- Reveals verified emails and direct phone numbers for matched contacts.
- Connects to Salesforce, HubSpot, Pipedrive, Clay, Attio, and Zapier.
- Callable directly via API or MCP for agents and automations.
- Holds SOC 2 Type II certification and follows GDPR rules for handling customer data.
It works best as one step in a bigger pipeline, not standalone.

Runs well with
The tools we'd run next to Ocean.io, and what each pairing covers.
Choose it, or skip it.
Choose it if
- In-house GTM teams with a handful of great existing customers who want more accounts that look and act the same, fast.
- Teams running account-based marketing who need to cluster closed-won accounts into a lookalike ICP instead of hand-building filters.
- Small teams that want a usable account list from a self-serve UI without a sales call or onboarding project.
- Teams already on Clay, HubSpot, or Pipedrive that want lookalike accounts feeding an existing enrichment or CRM workflow.
Skip it if
- Teams that need deep, verified contact-level data (direct dials, mobiles) at volume: contact coverage trails dedicated data providers.
- Teams sourcing from events, maps, or other offline signals: matching runs off crawled company web data only.
- Teams that want to pay in small, irregular amounts: subscriptions have a 9,000-credit minimum, and monthly billing costs more per credit than committing to yearly.
If not Ocean.io, then what.
- Apollo.iofree tier (no card) + paid plans from ~$49-59/mo/user (annual billing)
Pick Apollo.io instead when the main need is a large contact database plus built-in outreach, not lookalike discovery.
- CognismCustom quote only, no public pricing; third-party estimates suggest roughly $15-25k/yr platform fee plus $1.5-2.5k/user/
Pick Cognism instead for phone-verified contacts and intent signals at bigger team scale.
- ClayFree tier (100 credits/mo) + paid plans from $167/mo (Launch); enterprise custom quote
Pick Clay instead when the priority is a flexible enrichment waterfall across many data sources.
Asked in real client work.
What does Ocean.io actually search for?
Not a general contact database. You give it a URL for a company you've already closed (or a few), and it returns other companies that look and behave similarly, based on how those companies describe themselves online rather than just industry codes or headcount. It's built for expanding a proven customer pattern, not for cold-searching an unfamiliar market from scratch.
Is Ocean.io a replacement for Apollo.io or Cognism?
No. Those are contact databases built for finding and verifying individual people at scale across a huge range of companies. Ocean.io is narrower: it finds companies (and some contacts) that resemble ones you already sell to. Teams commonly run Ocean.io for account discovery, then hand the resulting list to a contact-data tool for outreach.
How is Ocean.io priced?
Paid plans run on a credit-based system, either pay-as-you-go or subscription, with monthly or yearly billing (yearly is cheaper). Subscriptions start at a 9,000-credit minimum. Credits get spent on verified email reveals, phone-number reveals, and extra search results, so usage volume, not seats, is what determines what a team needs. Every plan includes unlimited seats and API access; larger teams can get custom volume pricing through a sales call.
Can Ocean.io be called from an agent or workflow instead of used as a dashboard?
Yes. Ocean.io publishes a documented REST API covering search, enrichment, and discovery, so an agent or automation (Clay, n8n, custom scripts) can call it directly instead of a person clicking through the UI. That makes it usable as a step inside a larger account-discovery pipeline, not just a standalone tool.
