Born in the Trenches of B2B Sales
FractionalBDR.ai started by bringing together seasoned BDRs who spent years prospecting across the B2B landscape, working with agencies of every size, mastering different frameworks and models. When the AI revolution arrived, we saw the opportunity to marry that deep human expertise with technology that could scale it. That's how FractionalBDR.ai was born.
From Experience to Innovation
Our founders spent years in the trenches of B2B prospecting. Not at one company, not with one playbook, but across dozens of agencies, startups, and enterprises. They learned what works, what doesn't, and why most outbound programs fail.
The common thread? The best results always came from experienced reps who understood strategy, not just activity. But scaling that expertise was the challenge.
Then AI changed everything. Suddenly, the personalization, research, and strategic thinking of a Senior Fractional BDR could be amplified tenfold. We built FractionalBDR.ai to be the bridge between deep sales expertise and modern AI capabilities.

With 20+ years of enterprise B2B sales experience across agencies, startups, and global enterprises, David built FractionalBDR.ai to solve a problem he saw firsthand: companies burning budget on junior BDRs who lacked the strategic depth to land enterprise meetings.
Today, David leads a team of senior fractional BDRs powered by Ranger Agent, an AI-agentic research stack that turns deep account intelligence into qualified pipeline. Based in Miami and traveling to offices in Barcelona, Boston, and beyond, he works with B2B companies navigating complex sales cycles and $50K+ deal sizes.
