Aviato's REST API delivers detailed individual-level data — contact information, skills, work history, and social profiles — alongside deep company data including financials, web traffic, tech stack, and industry classification. Near-daily refresh rates ensure that data in automated pipelines reflects current reality, not stale snapshots from quarterly crawls.
Aviato surfaces proprietary signals not available in traditional data tools: company credit card revenue estimates, employee vesting schedules, and real-time tracking of where top engineers are moving. Early customers include NEA, Republic Capital, and 8VC, who use the platform to source and qualify early-stage startups before they appear on Crunchbase or PitchBook.
As a native Clay integration, Aviato enriches contact and company records within Clay tables — finding professional profiles, personal emails, normalizing locations, and analyzing private companies through financial enrichment and acquisition history. This makes it particularly useful for growth teams building AI-augmented outreach workflows that require the freshest possible underlying data.
Instantly find verified emails and direct-dial phone numbers for any prospect via LinkedIn, company websites, or bulk search — with no lag from stale databases.
Generate AI-crafted talking points, pain points, and personalized outreach messages for each prospect based on their role, company, and industry.
Automatically enrich and update CRM records in Salesforce, HubSpot, and Pipedrive with fresh contact data, reducing manual entry and keeping pipelines accurate.
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.
Most B2B data providers refresh their datasets monthly or quarterly due to the computational cost of continuous crawling and validation. Aviato re-processes key data signals on a near-daily basis, meaning that when you query a person or company, you're seeing data that reflects their current state — not their state from 90 days ago. This matters significantly for tracking fast-moving signals like engineer movements between companies or headcount changes at startups, where stale data leads to missed opportunities.
Aviato does not publicly disclose the methodology behind its credit card revenue estimates. Based on what's known, the signals are derived from a combination of proprietary data partnerships, payment ecosystem data, and AI modeling applied to observable company signals (transaction volume indicators, web commerce patterns, job postings related to finance roles). These are estimates, not verified figures, and should be used as directional signals rather than audited financials.
Yes. Aviato has a native integration with Clay, which means growth teams and operators who use Clay for workflow orchestration can access Aviato's data through Clay's no-code interface without building a direct API integration. In Clay, Aviato appears as a selectable data provider and can be used to enrich people and company fields within any Clay table. This is the primary non-API access path available today.
People Data Labs and Clearbit have larger, more established datasets with broader geographic coverage and stronger enterprise track records. Aviato's differentiator is data freshness and its unique private-market signals — vesting schedules, credit card revenue, and engineer movements — that PDL and Clearbit do not provide. For teams that need the deepest available coverage on the most common B2B profiles, PDL or Clearbit may offer better recall. For teams that specifically need current, high-signal data on the private tech ecosystem, Aviato's freshness and proprietary signals make it the stronger choice.
Aviato's stated early customers include NEA, Republic Capital, and 8VC — all venture capital firms. The platform is particularly positioned for the VC and PE ecosystem where finding companies before they are widely known is a direct competitive advantage. That said, the Clay integration and the general people and company API attract growth teams at tech companies who need fresh enrichment for outbound and ABM workflows. Given the company's early stage (33 employees, founded 2021), the customer base is still concentrated in the investment sector.
Aviato 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.
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.
Not officially — Seamless.AI 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.
