Ocean
Find your next customers, not just more contacts
What is Ocean
Ocean.io crawls company websites, normalizes the data into structured profiles, and uses AI segmentation to find companies and people that look like your closed-won customers. It's built for SDRs, BDRs, founders, and GTM engineers at solo operations and SMBs who need to move from "gut-feel ICP" to a data-backed target list without a large ops team. The standout capability is its lookalike search: feed it your existing customers and it predicts future ones by analyzing behavioral and firmographic signals from across the web, not just static database fields. Verified emails cost one credit each and direct mobile numbers cost ten, with waterfall enrichment pulling from 16-plus sources to fill gaps. Where it falls short is depth of sequencing and engagement tooling — Ocean.io surfaces and enriches the list, but you'll need a separate tool to run the actual outreach.

Vanderbuild take
Ocean.io sits at the intersection of lookalike finding, email discovery, and data enrichment — and for SDRs, founders, and GTM engineers who need to define and work a TAM without a full RevOps stack, it's one of the more focused tools in this category. The agentic story here is genuinely native: Ocean.io ships an MCP server alongside its public API and webhooks, which means you can wire it directly into an AI agent orchestration layer without any middleware gymnastics — that's a real differentiator in this subcategory. Pricing starts at $64/year for 9,000 credits, which is low-risk enough to test against your actual ICP before committing. The honest limitation is that Ocean.io stops at the list — there's no built-in sequencing, multichannel outreach, or engagement tracking, so you'll be stitching it to a separate sending tool from day one.
Agentic stack profile
MCP serverYesLive MCP server — agents can call this tool directly.
Connects AI assistants (such as Claude and Cursor) directly to the Ocean.io API to access B2B company and people data, enabling company lookup/enrichment and discovery based on semantic similarity, technologies, or industries.
Open MCP →APIRESTProgrammatic access available.
REST API — straightforward to call from any agent or workflow tool. Rate limits and auth vary by plan.
API docs →Agentic readinessNativeBuilt for agents from the ground up.
MCP server + agent-friendly API + at least one autonomous workflow out of the box. The bar for 'Native' is high — only a handful of tools currently qualify.
Stack roleData source · EnricherWhere this tool slots into an agentic pipeline.
Plays the role of Data source + Enricher in an agentic pipeline. Use it to source contacts, companies, and the raw inputs an agent needs to act; add firmographic, technographic, and signal data to a lead row on the fly.
