Where our data comes from
LeadTale maintains a B2B database for professional outreach. The database focuses on work-related information: name, job title, employer, professional email address, professional phone number, general work location, company attributes, and professional profile links.
No single source is treated as enough by itself. We combine public business information, licensed feeds, customer-provided signals, AI-assisted structuring, and proprietary verification. The goal is practical and narrow: help sales and marketing teams find the right business contacts, with enough context and accuracy to use that information responsibly.
Public web data
Publicly available company directories, official company websites, public press releases, public regulatory filings, and other sources that businesses publish for professional discovery.
Partner data feeds
Licensed data partnerships with providers that represent they have the rights and controls required to provide B2B business-contact data.
User-contributed observations
Signals contributed by LeadTale users as they prospect, enrich records, correct outdated information, or confirm that a professional is associated with a company.
AI-assisted enrichment
Large-language-model assisted extraction and structuring from public web sources, including both structured pages and unstructured business content.
Email pattern detection
Proprietary inference of company email patterns from observed verified emails, used together with verification checks before a contact result is returned.
Verification methodology
Source data does not become a LeadTale result automatically. We normalize records, compare them against corroborating signals, score confidence, and verify contact channels before returning data to customers. Email verification can include domain analysis, pattern checks, mailbox-level signals, catch-all handling, and other deliverability checks designed to reduce bounces.
Our verification system is described in more detail on the Email Verification Methodology page. That page explains how LeadTale evaluates accuracy, how credits are charged, and why failed lookups do not consume credits.
Data quality standards
B2B data changes constantly. People move roles, companies update domains, phone numbers change, and public pages go stale. LeadTale's quality program is built around re-validation rather than one-time collection.
Freshness
Records are continuously re-validated. We track decay, prioritize records that show signs of change, and suppress stale data when confidence drops below our standards.
Accuracy
We look for multi-source corroboration, confidence scoring, and verification evidence before presenting contact data. User corrections feed back into the quality pipeline.
Compliance
We honor Global Privacy Control signals, maintain opt-out and suppression mechanisms, and publish transparency information for Article 14 GDPR purposes.
What we don't do
- We don't sell raw data via API to anyone. LeadTale provides a verified data platform for sales and marketing teams, with usage controls, account terms, suppression handling, and customer obligations.
- We don't bypass platform terms. Our browser extension uses each user's authorized access to their own browsing context and returns LeadTale data inside that workflow. It is not permission to circumvent any third-party platform's restrictions.
- We don't store personal data without a lawful basis. We limit the database to professional B2B information and rely on the legal bases described in our Privacy Policy, including legitimate interest for appropriate B2B prospecting use cases.
- We don't ignore removal requests. Verified opt-out requests are removed from active production systems and added to suppression controls designed to prevent re-inclusion from later sources.
Removing your data
If you are a professional whose information appears in LeadTale and you want to access, correct, restrict, or remove it, submit a request through leadtale.com/privacy/remove. You can also email privacy@leadtale.com.
We verify requests, remove confirmed records from active production systems within the timelines stated in our Privacy Policy, and retain suppression information so the same contact details are not re-added from another source.
