Ocean.io Review 2026
Last reviewed June 2026
Ocean.io
Lookalike company sourcing and firmographic data
Overview
Ocean.io turns one good-fit account into a list of companies that look just like it, using firmographic and lookalike modeling. For the curated-ICP motion — 200 to 500 tightly-matched targets rather than industrial scraping — it's the fastest way to expand a seed list without losing relevance. It shines when you already know what a winning account looks like; it's wasted if your ICP is still fuzzy.

Ocean.io vs Apollo?
Apollo is a broad database; Ocean is a lookalike engine for expanding a precise ICP.
