VENTURE

Sometimes extraordinary leaders need a partner to build businesses with - not just investment dollars - we call this venture development. 

We combine our time and talent, as well as capital, to build businesses from the ground with these leaders.

Our ventures, as well as our partnerships, are mission driven, living up to the positive charge in our name, Proton.

And our focus lies in two distinct fields:

HEALTH & WELLNESS

Probiotics | Hydration | Senior Nutrition

C
IP COMMERCIALIZATION

Deep Tech | IoT | Medtech

Each year billions of dollars is invested into technology and research developed by brilliant thinkers. 
 
Some of the most critical technologies of our time will be born from these research laboratories, brought to life in partnership with dedicated operators, and patient capital.
Projects span from regenerative medicine and orthopedics to machine learning and wireless transmission.
