I build qualified B2B prospects using Clay, AI, and LinkedIn — combining automation with real-world profile and company intelligence.
Clay helps accelerate enrichment and data collection.
AI helps research and qualify companies and prospects at scale.
LinkedIn helps validate the information, confirm roles, understand the person and company, and add context that automated data alone may miss.
My workflow:
ICP → Company Targeting → Decision-Makers → Clay Enrichment → AI Research → LinkedIn Validation → Outreach-Ready Prospects
I can work with criteria such as:
→ Industry
→ Location
→ Company Size
→ Job Title & Seniority
→ Technology
→ Funding & Growth
→ Hiring Activity
→ Custom ICP Requirements
A 250-prospect project can often be completed in 3–5 hours, depending on the research depth and targeting requirements.
The result is not just a collection of contacts.
It is a qualified prospect dataset with the right companies, right people, enriched information, and additional LinkedIn validation — ready for your sales team to act on.
Ideal for:
• B2B outbound campaigns
• SaaS prospecting
• Agency prospecting
• Account-based targeting
• New-market research
• Sales pipeline development
• Ongoing prospecting
Clay gives me the speed.
AI gives me scale.
LinkedIn adds human-level context and validation.
Together, they create a faster and more reliable way to build B2B prospects.
