Dr. Leon Eisen’s journey spans science, breakthrough medical technology, entrepreneurship, venture capital, and startup growth.
Leon earned a PhD in Physics from the Weizmann Institute of Science and began his career in quantum optics, laser technology, and advanced research. He later moved into industry, becoming an engineer, technology executive, and entrepreneur. As his career expanded into business, he also studied at Harvard Business School, strengthening his understanding of strategy, leadership, and company building.
He went on to become a four-time founder and inventor, holding multiple patents and creating the world’s first FDA-cleared wrist-worn medical monitor.
His entrepreneurial journey also taught him the realities of fundraising. During the 2008–2010 financial crisis, Leon raised his first million dollars and ultimately more than $20 million for his company.
Years later, after working on both sides of the investment table, he realized that fundraising is not driven by technology, traction, and pitch decks alone. Investors also respond to signals, perceived risk, momentum, credibility, founder behavior, and the many factors that create conviction.
That insight became the foundation of his work today.
Leon is a Venture Partner at Network VC, a WBAF Senator, and a startup advisor and mentor. He works selectively with Pre-Seed to Series A founders to help transform promising companies into fundable investment opportunities.
He is the creator of Fundables OS™ and the Eisen Fundability Score, frameworks designed to identify and improve the factors that shape investor conviction and fundraising outcomes.
His core belief is simple:
Great companies do not automatically become fundable companies. Fundability must be engineered.
Leon is also the author of Invisible Game: The Secrets of the Term Sheet Magnet, which draws on more than two decades of experience as a scientist, inventor, founder, executive, advisor, and investor.
His work focuses on one central question:
What makes an investor want to invest?
Today, Leon helps founders build stronger companies, create investor conviction, become more fundable, and raise capital more effectively.
