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.

Crunchbase specializes in private company funding data, investor relationships, and M&A signals that LinkedIn does not track. While LinkedIn excels at individual professional profiles and network-based outreach, Crunchbase provides the full financial history of a company — every funding round, lead investor, valuation estimate, and acquisition event. For sales teams who use funding triggers as their primary prospecting signal, Crunchbase provides richer structured data than LinkedIn's company pages.

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.

Yes. FullEnrich shows which provider in the waterfall cascade returned the successful match for each contact. This transparency lets teams evaluate provider quality over time and understand which sources are delivering the highest hit rates for their specific prospect segments.

Yes — FullEnrich credits roll over for up to 3 months, which is a meaningful differentiator from tools like Snov.io or Apollo where credits expire at the end of the billing period. This makes FullEnrich more forgiving for teams with variable monthly enrichment volumes.

Yes. Phone number lookups cost more credits than email lookups — 1 phone number found costs approximately 10 credits, while email enrichment costs less per match. Credits are unified (not split into separate email and phone pools), so you can allocate the same credit balance across either type of enrichment based on your campaign needs.

FullEnrich consistently delivers 65–85% match rates versus the 25–40% typical of single-source providers like Apollo or Lusha. The waterfall approach — cascading through 20+ providers before returning no result — captures matches that any single provider would miss. Users also report bounce rates below 2% versus 15–30% with tools that rely on a single data source.

FullEnrich is an enrichment-only tool — it has no built-in prospecting database. You must supply an existing list (LinkedIn URLs, company domains, or contact names) to enrich. Teams typically pair FullEnrich with a list-building tool (LinkedIn Sales Navigator, Apollo's search, or a CSV export) then run the list through FullEnrich's waterfall to append verified emails and phone numbers.

Both use multi-provider waterfall logic, but they serve different buyer profiles. FullEnrich is a standalone enrichment tool focused purely on maximizing email and phone match rates — it is simpler, cheaper, and requires no technical setup. Clay is a broader GTM workflow platform where waterfall enrichment is one of many features alongside AI research, signal tracking, and CRM automation. Clay typically costs 3–10x more than FullEnrich for equivalent enrichment volume. Teams that just need high-coverage contact data will usually find FullEnrich more cost-effective; teams building complex enrichment and outreach automation benefit from Clay's additional capabilities.
