Jeffrey Tiefenthaler

Founding GP & Fund Manager

"Most investors focus on returns without questioning the denominator those returns are measured against."

Jeffrey began his career at Microsoft in 2011, where he developed a deep passion for combining technology with financial markets. Over the years, he built and licensed proprietary investment management and auto-order execution software — delivering over 300 algorithms to trading partnerships and high-net-worth individuals globally.

That foundation in systematic, technology-driven investing became the bedrock of BDG's approach. Jeffrey brings a rare combination: the technical fluency to build the systems, and the market experience to know what those systems should optimize for.
