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.
Funding data is typically updated within days to weeks of a round closing, sourced from SEC filings, press releases, investor announcements, and community contributions from founders and investors. For major rounds at well-covered companies, data often appears within 24–48 hours. However, for smaller rounds or non-US companies with limited press coverage, there can be delays of weeks or the data may be missing entirely. The platform's 80 million+ user community helps keep high-profile profiles fresh.
Yes, but with significant caveats. Executive profiles include names, titles, and LinkedIn links across all paid plans. Business plan subscribers and above can access email addresses for key contacts. However, Crunchbase's contact coverage is much thinner than dedicated contact data providers like ZoomInfo, Apollo, or Lusha — it is primarily a company intelligence platform, and its people data is a supplementary feature rather than a core strength.
Yes. Crunchbase has a dedicated API that supports 6 billion+ calls annually across its customer base, enabling programmatic data access for warehouse ingestion. In 2025, Crunchbase partnered with Databricks to make its predictive private company intelligence available via the Databricks Marketplace, significantly simplifying enterprise data team workflows. Custom Enterprise contracts support data licensing arrangements for larger data delivery needs.
The free account provides limited access to company profiles, basic search, and a restricted number of profile views per month. Crunchbase Pro ($49/month annual or $99/month) unlocks unlimited profile views, advanced search filters, saved searches and alerts, CSV exports (up to 2,000 rows), CRM integrations, and access to the AI-powered Crunchbase Scout agent. The 7-day free Pro trial lets users evaluate the full feature set before committing.
Crunchbase uses machine learning trained on historical funding patterns, growth signals, investor behavior, and market timing to generate predictive scores for funding likelihood, acquisition probability, and IPO readiness. These predictions are intended as directional signals rather than certainties — they help prioritize research and outreach, not replace due diligence. Crunchbase does not publicly disclose the precision/recall performance of its prediction models.
Not officially — Crunchbase 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.
Unlike static databases that are refreshed periodically, Seamless.AI re-crawls and verifies contact data at the moment of each search. This means you're getting the most current available information rather than data that might be months old — though the real-time nature doesn't guarantee 100% accuracy, as user-reported bounce rates average 15–25%.
One credit reveals one contact — including email address, phone number(s), and associated firmographic insights. Credit rollover policies vary by plan; the free tier provides 50 lifetime credits, while paid plans typically do not roll over unused credits month to month. Pro and Enterprise plans can negotiate rollover terms in their annual contracts.
Yes — the Chrome extension works on LinkedIn profiles, company websites, and other web pages. When browsing a company website or individual's professional page, the extension can attempt to surface contact information. However, LinkedIn is the primary and most reliable surface for the extension.
Seamless.AI's AI pitch intelligence analyzes a prospect's role, company, industry, and available signals to generate personalized talking points, pain points, and outreach angles specific to that individual — rather than generic templates. This is designed to help reps craft more relevant opening lines and cold call scripts without spending time on manual research.
Cancellation is one of the most frequently cited complaints in user reviews. Seamless.AI requires written cancellation notice within a specific window before contract renewal, and many users report difficulty navigating the process. Pro and Enterprise plans are annual contracts, and failure to cancel within the specified notice period often results in automatic renewal. Always review the contract terms carefully before signing.
Seamless.AI has global coverage but its database and data quality are strongest for North American contacts. International coverage — particularly for EMEA and APAC — is less comprehensive, and phone number accuracy for non-US contacts is notably lower. Teams focused heavily on international markets may want to supplement with providers that specialize in those geographies.
