Ocean.io
Ocean.io finds similar companies to your best customers and enriches them with firmographic and technographic data. It is less about contact enrichment and more about account discovery and segmentation. Teams use it to build lookalike lists for ABM campaigns.
Official site ↗Why it ranks here
Strong pick for account-based enrichment and lookalike discovery. The firmographic coverage is excellent and the similar company algorithm works well. It does not compete with Clay on contact enrichment or workflow orchestration.
Where it sits
Ocean.io excels at account discovery and firmographic depth; Clay is stronger on contact enrichment and workflow flexibility. For ABM motions that require finding lookalike companies, Ocean.io fits the use case directly.
How GTM Engineering teams use it
Marketing and RevOps teams upload a list of ideal customer accounts, Ocean.io finds similar companies, enriches them with firmographic and tech stack data, and exports the list to Salesforce or a MAP.
In-depth notes
Annual contract pricing, not credits. The similar company algorithm is the core value; if you do not need lookalike discovery, other tools are more flexible. Integration with CRMs is straightforward. Best for ABM-focused teams that prioritize account targeting over contact enrichment.

Setup
Upload a CSV of 10 to 20 ideal customer accounts, let Ocean.io build a lookalike model, and review the similar companies it returns.
First thing to build
Feed Ocean.io your top 20 customers by ARR, generate a lookalike list of 500 similar companies, enrich with firmographics and tech stack, and export to Salesforce as target accounts.
What actually matters
- Adjust similarity threshold to control list size and quality
- Filter by employee count, revenue, or tech stack before exporting
- Enable CRM sync to auto-update account records with firmographic changes
Watch out
Teams export thousands of lookalike accounts without filtering and overwhelm their SDR team with low-quality targets.
