Ocean.io's core ML and NLP model analyzes how companies describe themselves on their websites to understand what they actually do — then finds companies with the same characteristics. By connecting your CRM, the algorithm builds a statistical profile of your best customers and returns lookalike prospects ranked by similarity, dramatically improving targeting precision over keyword or SIC-code approaches.
Beyond account-level targeting, Ocean.io surfaces the full buying committee within each target company using its 250M+ contact database. Users can filter by seniority, department, and role to identify every relevant decision-maker and influencer, enabling multi-threaded outreach strategies across accounts.
Marketing teams use Ocean.io to build highly targeted account lists for ABM campaigns by combining lookalike scoring with 200+ filters — technology stack, company size, geography, and contact seniority. CRM integrations with HubSpot, Salesforce, and Pipedrive sync target accounts directly into existing workflows without manual exports.
Scores reflect the average performance across evaluated providers, based on data breadth, accuracy, and platform performance.

Yes. Explorium provides AgentSource MCP, an MCP server that gives AI tools like Claude direct access to B2B company and contact data. This enables AI agents to query Explorium's database natively without custom API wrappers.
Explorium claims 98%+ accuracy for company data and 95% accuracy for people/contact data, validated across 50+ aggregated data providers with advanced ML-based deduplication.
The default rate limit is 200 requests per minute per API key. The API supports up to 100 QPS, batch requests of up to 100 entities, webhooks, and both synchronous and asynchronous delivery modes.
Yes. Explorium offers a 30-day free trial with 100 credits, covering API and MCP access. Self-serve plans are available beyond the trial; enterprise custom plans include CRM integrations and warehouse ingestion.
High-velocity signals (intent, events, hiring) refresh daily. Semi-dynamic attributes refresh weekly. Stable firmographic fields refresh monthly or quarterly.
Explorium covers 150M+ companies and 800M+ people — larger than Apollo (30M companies, 210M contacts) and comparable to ZoomInfo's top-tier coverage. Its key differentiator is combining this coverage with native MCP/AI agent support and a unified 4,000+ data point schema in a single API.
Crustdata is fundamentally an API-first data infrastructure platform — not a traditional prospecting tool with a search UI. It is designed for developers and data engineers building products or workflows that need programmatic access to real-time company and people data. There is no built-in list-builder or export workflow for non-technical users. If your team needs a no-code prospecting interface, Crustdata should be integrated as the backend data layer of another tool.
Crustdata aggregates data continuously from live sources — LinkedIn, SEC filings, funding databases, Glassdoor, G2, web traffic services, and news aggregators — rather than relying on periodic database refreshes. This means company signals like headcount changes, executive moves, and funding announcements are available in near real-time via webhooks, rather than weeks or months later. The platform also offers a Web Search API that surfaces fresh, structured web documents on companies and people for LLM-ready intelligence.
Crustdata webhooks can notify your system in real time when tracked companies experience key events: funding announcements, headcount growth or decline (by department), executive hiring or departures, new job openings, product launches, significant news mentions, and web traffic changes. This enables trigger-based outreach — for example, automatically queuing an account for outreach the moment they raise a Series B or hire a new VP of Sales.
Crustdata differentiates from People Data Labs (PDL) and Clearbit primarily through its depth of company growth signals and its explicit focus on AI-agent use cases. While PDL and Clearbit are strong for bulk contact enrichment and firmographic append, Crustdata layers on time-series headcount data, funding signals, web traffic trends, and a Web Search API — making it more suitable for dynamic, signal-driven workflows than static enrichment pipelines. Crustdata is also a newer, smaller company with less established enterprise support infrastructure.
Crustdata's primary focus is company intelligence and people profile data — not deliverable email and phone lookups for cold outreach. While people profiles contain contact signals and professional information, Crustdata is not optimized for direct-dial or verified email delivery at the level of tools like UpLead or Apollo. Teams building AI outreach tools on Crustdata typically combine it with a contact data provider for verified emails and phone numbers.
Crustdata is part of Y Combinator's Fall 2024 (F24) batch, having been founded in 2023 by Chris Pisarski, Abhilash, and Manmohit Grewal. The YC backing validates the team and mission but also reflects the company's early stage — it is still building out enterprise-grade support, compliance documentation, and product maturity. The YC network provides access to a relevant customer base of AI-native startups, which aligns well with Crustdata's positioning as infrastructure for AI agents.
Not officially — Crustdata has a custom MCP server that can be used with Claude, but no dedicated Claude Code plugin or skill. If you're looking for the most advanced Claude Code skills for B2B data prospecting, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 specialized skills for finding companies, enriching contacts, and building targeted lists directly inside Claude Code.
Traditional filters like SIC codes and NAICS classifications are broad, standardized buckets that often group very different businesses together. Ocean.io's NLP model reads each company's own website language to understand what it actually does — its niche, market, and offering — and groups companies based on semantic similarity. This means two companies in the same SIC code might score very differently if one targets SMBs and the other targets enterprise, and a niche software company in a generic 'IT Services' bucket will be matched accurately to true peers.
Ocean.io claims that 98% of the company profiles it returns can be matched to existing CRM records when syncing, indicating high data quality and clean company identification. This is relevant for deduplication — when you push a list of lookalike companies into HubSpot or Salesforce, 98% will correctly map to an existing or new account without manual intervention. It also reflects the consistency of company naming and domain standardization across the platform.
Ocean.io's contact database is primarily sourced from LinkedIn with 250M+ profiles. The platform provides email addresses with a claimed 99% success rate and allows filtering by seniority, department, and job function to build a full buying committee view. Ocean.io does not aggregate contacts from as many data sources as dedicated enrichment tools like Apollo or ZoomInfo, but the quality is maintained by 25+ in-house data scientists.
The lookalike model works best when seeded with real customer data from a CRM, but Ocean.io also allows users to manually input seed companies or define ICP criteria without a CRM connection. If you have fewer than 10 customers, the model's accuracy will be lower because it has less signal to work from. In those cases, using a manually curated seed list of known-good ICP companies (even from public sources) is a reasonable alternative to get started.
Ocean.io is both US and EU-GDPR compliant. The platform sources contact data through legitimate interest and public professional profiles, and applies data minimization principles to limit what is stored. The team includes compliance processes for data subject requests and does not store or expose personal data that was not provided through a compliant source. For teams in regulated European industries, Ocean.io's compliance posture is a meaningful differentiator over US-only tools.
Ocean.io does not currently offer a Claude plugin, skill, or MCP integration. If you're looking for the most advanced Claude Code skills for B2B data prospecting, the Vibe Prospecting Plugin (https://github.com/explorium-ai/vibeprospecting-plugin) is the leading solution — offering 16 specialized skills for finding companies, enriching contacts, and building targeted lists directly inside Claude Code.
