Gabriel A. Kasabdji
Co-Founder and CEO of InterStock
Gabriel A. Kasabdji is the cofounder and Chief Executive Officer of InterStock LLC, a financial education company dedicated to transforming how students engage with personal finance and investing. Under his leadership, InterStock has grown into a recognized program serving middle and high school students across South Florida, helping young people build strong financial foundations long before they enter college or the workforce.

Gabriel's journey into finance began as a teenager, captivated by the pace and depth of the markets. What started as a personal curiosity quickly became a passion. He spent his early years learning everything he could about trading, economics, and investor psychology. He would focus on studying price movements, analyzing strategies, and executing trades with real capital. What he realized along the way was that most students, even those with strong academic backgrounds, had little to no exposure to the financial world.

Instead of waiting for change in the education system, Gabriel decided to build it himself.

In 2022, he cofounded InterStock with a mission to bring real world finance education into the classroom and equip students with tools typically reserved for professionals. Gabriel designed the curriculum to be dynamic, engaging, and activity based, with an emphasis on market participation, risk awareness, and critical thinking. The goal was not just to teach investing, but to build confidence, discipline, and long term perspective.

What began as a pilot at a single school quickly expanded as parents, students, and educators alike recognized the program’s impact. Today, InterStock partners with some of the most respected schools in Miami, offering semester long programs, private training, and internship opportunities. The company also hosts trading competitions, career workshops, and offers lifetime mentorship for select students pursuing careers in finance.

Gabriel is deeply committed to shaping a new generation of financially literate and empowered young leaders. Through InterStock’s growing alumni network and partnerships, he continues to create bridges between high performing students and top tier opportunities in investment firms, banks, and hedge funds.

Gabriel believes the future of finance belongs to those who start early, and InterStock is only the beginning.

Co-Founder and CFO of InterStock
Christian E. Kasabdji is the Co-Founder of InterStock, a financial education program dedicated to teaching middle and high school students about investing and the stock market. He has been passionate about finance since first discovering the stock market in 9th grade at Belen Jesuit Preparatory School. A simple news article showcasing the market’s biggest winners and losers sparked his curiosity, leading him down a path of research, trading, and continuous learning.

Christian’s fascination with the complexities and intricacies of the stock market soon turned into a deep passion for financial research, specifically in areas such as options, stocks, and bonds. Driven by curiosity and determination, he immersed himself in analyzing financial instruments and market dynamics, continually refining his skills and knowledge.

Determined to gain hands-on experience, Christian started reading earnings reports, analyzing stock charts, and eventually opening his own brokerage account. Over the years, his deep involvement in the market helped him develop expertise in stocks and options trading, reinforcing his belief that financial education should be accessible to students at an early age.

Motivated by this vision, he co-founded InterStock to give students the opportunity he wished he had growing up. Today, InterStock has partnered with prestigious schools such as Carrollton, Belen, Columbus, La Salle, and Doral Academy, reaching nearly 200 students annually. The program recently introduced an advanced class designed for students eager to explore complex trading strategies.

Christian’s greatest achievements go beyond numbers; he values the positive feedback from parents and professionals in the hedge fund industry, reaffirming the impact of his work. His primary focus is ensuring that every student receives the best possible learning experience, equipping them with the knowledge and skills to grow.

InterStock also gives back by donating a portion of its revenue to the schools it partners with, supporting their educational needs and initiatives. Christian is currently pursuing a Finance degree at Florida International University, where he has been on the Dean’s List every year while managing InterStock. He graduated from Belen Jesuit Preparatory School in 2021 as a member of the National Science Honor Society.
