Stop wasting time on outdated lead lists. Get custom-built B2B contact databases with verified emails, direct dial phone numbers, and LinkedIn profiles of the decision-makers who matter most — targeted to your exact Ideal Customer Profile (ICP). Exclusive data, never resold, with 95%+ email deliverability guaranteed. Serving sales teams across the USA, UK, and Canada.
Why Custom-Built Contact Lists Outperform Purchased B2B Databases
If your sales team in the USA, UK, or Canada is still relying on purchased lead lists from providers like ZoomInfo, Apollo, Lusha, or Seamless.AI, you're likely dealing with outdated contacts, shared data, and poor deliverability. Industry research shows that purchased databases have 30-50% inaccuracy rates, generate 60% more spam complaints, and are shared with dozens of your competitors — meaning you're all contacting the same prospects with the same pitch.
Custom-built contact lists, researched and verified to match your specific Ideal Customer Profile (ICP), deliver dramatically better results. Our clients consistently see 3-5x higher email response rates, 2x faster sales cycles, and 40% lower cost-per-meeting compared to purchased data. When every contact is hand-researched, multi-source verified, and exclusive to your team — your outbound campaigns convert at significantly higher rates.
Wingspan Global Solutions builds B2B contact databases from scratch using multi-source research, verification, and enrichment. Every list we deliver is 100% exclusive to you — we never share, resell, or reuse your data with other clients or competitors. This exclusivity advantage is what makes our contact discovery service the preferred choice for 200+ sales teams across the USA, UK, and Canada.
Our Contact Discovery Process — From ICP to CRM-Ready Data
We start by defining your Ideal Customer Profile with granular precision: target industries, company size (employee count and revenue), geographic targeting (specific states, cities, postal codes, or nationwide coverage across USA, UK, and Canada), technology stack, growth signals, and target job titles (C-suite, VP, Director, Manager, or specific functional roles). This ensures every contact we deliver is a genuine potential customer — not a random database entry.
Our researchers use LinkedIn Sales Navigator, industry databases, company websites, SEC filings, Companies House (UK), EDGAR filings, press releases, job postings, and proprietary tools to identify, gather, and verify contact information. Multi-source validation ensures higher accuracy and coverage than any single data provider. Every contact goes through: email verification (syntax + domain + mailbox + catch-all check), phone validation (carrier + line-type detection), LinkedIn profile confirmation, and company website verification.
We deliver CRM-ready data in your preferred format — CSV, Excel, or direct import to Salesforce, HubSpot, Pipedrive, Outreach, Salesloft, or any other CRM/sales engagement platform. We guarantee 95%+ email deliverability — any contacts that bounce within 30 days are replaced free of charge. Data fields include: full name, job title, company name, verified email, direct dial phone, LinkedIn URL, company size, industry, revenue range, and technology stack.
