About Xontogeny

Xontogeny (zon-TOJ-uh-nee) is a biotech aggregator with a differentiated business model to support the accelerated development of life science technologies in the pursuit of helping patients with serious diseases. Specifically, we partner with entrepreneurs, providing the leadership and operating experience needed to increase the probability of success with early drug and technology development.

At Xontogeny, we believe that scientific founders supply the passion and determination integral to the success of their companies. While the foundation of success is good science, how that science is developed from inception to maturity serves as the critical pathway. Therefore, we focus on supporting the entrepreneur’s pursuit and optimizing the development pathway with an exceptionally talented and experienced operational team. With our team’s track record of success, entrepreneurs of affiliated companies will gain the support and guidance they need while remaining lean, virtual, and without the financial burden of supporting a full-time team.

This dynamic model has the additional benefit of supporting the goals of the founding scientists and entrepreneurs to retain more control and equity, while increasing the chance of accessing investment, and ultimately development success.


We believe that founders are crucial to the success of a development program. We seek to support and guide scientific entrepreneurs through an optimized development pathway with an experienced operational team.
