Bad data doesn't just waste time.
It kills deals.

Every agent action in Tablestakes starts with data. If a contact record is stale, an email bounces. If a company's funding stage is wrong, the pitch misses. If a trigger event is missed, the window closes. We obsess over data quality because your agents are only as good as the information they work with.

📉
Bounced Emails
Unverified emails damage sender reputation, tank deliverability, and signal spam to inboxes. Every email the Lead Sourcing Agent finds is verified before it reaches your account.
🎯
Missed Signals
A prospect who raised 6 months ago and just hired a new CRO is in a buying window. An agent working on stale data misses it entirely. We surface real-time signals so your team never misses the moment.
🕳
Wasted Outreach
Reaching the wrong person at the wrong company wastes rep time and burns prospect goodwill. Verified titles, current roles, and enriched firmographics mean every contact is the right one.

Apollo.io

Apollo is the primary contact and company database powering the Lead Sourcing Agent. When a rep describes their ideal prospect, the agent translates that into a structured Apollo search — querying by job title, industry, location, company size, funding stage, and dozens of other filters — and returns verified, enriched contact records.

What agents use it for
  • Contact search by title, industry, location, and company attributes
  • Company firmographic data including headcount and revenue range
  • Funding stage filtering for Series A, B, C, and beyond
  • Direct dial and email data on paid tiers

Source 02 · Email Verification
Hunter.io

After the Lead Sourcing Agent finds contacts via Apollo, Hunter.io verifies and enriches email addresses before they're saved to your account. Only emails that pass Hunter's confidence threshold are marked as verified — protecting your sender reputation and ensuring high deliverability on every outreach campaign.

What agents use it for
  • Email address finding by name and company domain
  • Deliverability confidence scoring (0–100)
  • Bulk email verification for lead lists
  • Catch-all detection to avoid problematic domains

Source 03 · Company Enrichment
Clearbit

Clearbit provides deep firmographic enrichment for every company in the Tablestakes platform. When the Prospect Research Agent builds a brief, Clearbit supplies the underlying company intelligence — headcount, revenue estimates, technology usage, industry classification, and organizational structure — giving agents the context they need to generate a genuinely useful research summary.

What agents use it for
  • Company headcount and growth trajectory
  • Revenue range estimation
  • Industry and sub-industry classification
  • Technology stack detection
  • Employee count by department

Source 04 · Funding & Investor Data
Crunchbase

Crunchbase is the authoritative source for startup funding data in the Tablestakes platform. The Prospect Research Agent uses Crunchbase to surface funding rounds, investor names, valuation signals, and founding timelines — the signals that tell a sales rep whether a company has budget, is growing, and is likely to be evaluating new tools right now.

What agents use it for
  • Funding round history and amounts
  • Investor names and fund stage
  • Company founding date and age
  • Acquisition and merger history
  • Executive and founder profiles

Source 05 · Professional Signals
LinkedIn

LinkedIn signals give Tablestakes agents visibility into what's actually happening inside a target company right now. Recent hires, job postings, leadership changes, and headcount growth are all indicators that a company is scaling — and that a buying window may be open. The Research Agent uses LinkedIn signals to surface timing context that no other data source provides.

What agents use it for
  • Recent leadership hires and role changes
  • Open job postings as growth signals
  • Headcount growth over 30, 60, and 90-day periods
  • Department-level hiring patterns
  • Contact profile verification

LinkedIn data is accessed via compliant third-party enrichment partners, not direct API scraping.

Source 06 · Real-Time Web Search
Exa.ai

Exa provides the real-time web intelligence layer in Tablestakes — giving agents access to news, press releases, blog posts, product launches, and any public signal that indicates a prospect is in motion. Where structured databases tell agents who a company is, Exa tells them what's happening right now. It's the difference between a research brief that's technically accurate and one that's actually useful.

What agents use it for
  • Recent news mentions and press releases
  • Product launch and partnership announcements
  • Leadership commentary and public statements
  • Conference appearances and speaking slots
  • Competitive mentions and market moves
