At the leading edge of science committed to the future of stem cell medicine.
Harnessing the power of regenerative medicine to change the future of animal health.
The Gallant team is a collective of respected veterinarians, scientists, and some unbelievably dedicated entrepreneurs. Our work is the result of over 100 years of regenerative medicine experience, and a commitment to invest millions into the future of stem cell therapies.
Our best friends deserve better
Aaron Hirschhorn, founder of DogVacay, created Gallant after experiencing the power of regenerative medicine for himself. Traditional surgeries and injections proved unsuccessful, so Aaron underwent a single stem cell treatment to heal a debilitating back injury. The results were life-changing in more ways than one.
As a dog-lover, Aaron knew that our best friends could also benefit from this revolutionary approach to healing so he partnered with then CSO Dr. Linda Black to make it a reality. They created an autologous business to give pet parents short-term solutions while investing millions into “off-the-shelf” therapies for the future.
Gallant is venture-capital backed and funded by many of Silicon Valley’s most savvy investors. We're committed to investing millions in R&D for the future of regenerative medicine.
