Tranquillion

About

Tranquillion is a Colorado-based capital and philanthropy platform led by Principal and CEO Greg Fitzgerald, co-founder and former CTO of Solana, where he served as principal architect of the codebase. The firm deploys capital through both venture investment and philanthropy across climate, health, and arts & culture, supporting for-profit ventures and altruistic initiatives focused on building a healthier, more sustainable future. Tranquillion operates as a hybrid investment-and-grantmaking vehicle rather than a traditional fund. Notable investments span geothermal energy (Zanskar), grid infrastructure (Jubilee Transmission), regenerative medicine (Direct Biologics), and immersive arts (Culture House Immersive).
