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.
Detect high-intent buying signals such as new job postings for specific roles, product launches, funding rounds, and partnership announcements — enabling sales teams to reach out at exactly the right moment.
Enrich portfolio and target companies with structured growth signals — hiring velocity, technographic shifts, and news events — to surface promising startups and monitor performance over time.
Track sector-wide trends, monitor competitor activity, identify supply chain relationships via key customer data, and uncover new market opportunities using structured data on 100M+ companies.
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.
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.
No. PredictLeads is a company-level intelligence platform only. It tracks signals at the organizational level — job postings, news events, technographics, financing rounds, key customers, and firmographics — but does not provide individual contact records, email addresses, or phone numbers.
ZoomInfo and Apollo are contact databases with CRM-like prospecting UIs. PredictLeads is a data infrastructure provider — it delivers structured company signal datasets via API, webhook, and flat file, without a prospecting interface. It covers far more granular company event signals and is designed for teams building data pipelines, not individual sales reps looking up leads.
Job postings are refreshed approximately every 36 hours, providing near real-time visibility into hiring activity. News events are continuously tracked from 19M+ sources. Technographic data is updated as new signals are detected from website crawls, DNS records, and job descriptions.
Yes. PredictLeads offers 100 free API credits per month, which allows developers and data teams to test the API and evaluate data quality before committing to a paid dataset subscription.
PredictLeads supports REST API, webhooks, and flat file exports for integration with any downstream system. It also provides an MCP server for use with AI agents and LLM-powered workflows. There are no native CRM connectors, but data can be routed into Salesforce, HubSpot, or any other system via API or tools like Clay.
PredictLeads covers 100M+ companies globally across all industries, with particularly strong European coverage. News events are tracked from 19M+ PR sites, news outlets, and blogs worldwide. The platform participated in Y Combinator and has a global customer base including investment firms, data platforms, and enterprise intelligence teams.
