In early 2025 I was a **$2,400/month freelance digital marketer and lead generation specialist** running a small agency from Rajshahi, Bangladesh. Cold outreach was the backbone of my business, but sourcing high-quality B2B leads was expensive and frustrating. I relied on scattered tools and low-quality lists that delivered terrible bounce rates, spam complaints, and low reply rates. Good verified contact databases required expensive monthly subscriptions that ate my profits, while free options were outdated or inaccurate. I spent hours every week hunting for leads instead of closing deals, and my client acquisition stayed slow. My income remained flat while competitors with better data scaled faster.
Then I found **HappierLeads B2B Contacts Database** on AppSumo. I grabbed the lifetime deal at Five months later, I have instant access to **175 million+ verified B2B contacts** across 156 industries, download clean CSVs in seconds, run high-volume campaigns with excellent deliverability, and scaled my monthly revenue to **$8,900** while working only 25β28 hours per week. HappierLeads removed the biggest barrier to scaling my outreach and turned lead generation into a predictable growth engine.
