Carlos M. Martinez

Managing Director

An Austin resident for over 25 years, Carlos has a keen sense of trends and emerging opportunities. His ability to envision what is possible has taken him from land development, through the international art world, and most recently to legal cannabis. Over 4 years ago, Carlos shifted his focus from the Texas real estate market to the emerging opportunities in the rapidly-growing legal cannabis industry. In addition to this industry being a tremendous opportunity for investors, it unites Carlos’s passions as an advocate for wellness and health, personal liberty, social justice, and improving people’s lives and greater consciousness. Carlos is also an active advocate for Texas cannabis reform, and is frequently at the Texas State Capital. 

Carlos holds decades of experience in real estate, development, and capital raising. He has represented both buyers and sellers in multiple avenues of commercial transactions. While representing national developers, Carlos has had vast experience in performing market evaluations, project feasibility, investment analysis, financial structuring, and capital sourcing. With his trained eye, he has excelled at finding the most cost effective way to bring capital to projects while bringing a high return on investment. His greatest strengths are in building relationships, identifying high potential projects, and connecting opportunities with capital to create a prosperous path for these projects. More than anything, Carlos is comfortable exploring outside the box. He is an early adopter, and a visionary for a better future.
