Effective outbound starts long before the first email. It starts with finding the right accounts, identifying the right people, and building reliable contact data your team can actually use.
About
I’m Md. Naeem, co-founder of LeadsFriday. With 5+ years of experience as a full-time B2B lead generation specialist, I work with B2B agencies and sales teams that need dependable prospect data to support their outbound efforts.
My focus is researching the right companies, identifying relevant decision-makers, finding business contact information, and enriching prospect records with useful data such as verified email addresses and direct-dial numbers where available.
I care about relevance, accuracy, and clean delivery. The goal is to help teams spend less time manually researching contacts and more time building meaningful sales conversations.

Depending on the project and data availability, records can include company details, contact names, job titles, business emails, email verification status, professional profile URLs, and available direct-dial numbers.
