An entrepreneur at heart, Jason began his first business venture as a college student selling couches to his peers during Welcome Week at Michigan State University. After graduation, Jason partnered with his brother, Mike Teshuba, to form a web development company, generating over one million dollars in revenue through a variety of e-commerce platforms. The knowledge, expertise, and profits earned from these endeavors became the inspiration and building blocks that Jason drew from to launch Mango in August 2007.

Under Jason’s direction, Mango has grown to serve language learners through a variety of outlets around the world, including public libraries, universities, K-12 schools, government agencies, and corporations. Through his work, Jason aims to transform the language-learning sphere and enrich lives with language and culture through innovative product, marketing, and company strategies.

In 2010, Jason was included in Crain’s Detroit Business’ list of 40 under Forty innovative community leaders, and in 2014, Detroit Premier Business Journal honored Jason in their 30 in Their Thirties lineup of outstanding local entrepreneurs. Jason was also recognized by the Ernst & Young Entrepreneur of the Year Program as a Semifinalist in 2012 and a Finalist in 2015. Jason has served as Finance Chair of the Entrepreneurs’ Organization Detroit Chapter, as well as on the board of the National Museum of Language and Yad Ezra, a Jewish charity organization.

A native of Detroit, Michigan, Jason earned a bachelor’s degree in computer science engineering from Michigan State University. Fluent in English, Spanish, Brazilian Portuguese, Italian, Hebrew, and Greek, Jason has also studied Korean, Carpathian, and Russian, and is currently set on mastering Mandarin Chinese.

Through the process of prototyping and designing the original program interface of Mango in 2007 as Mango’s Creative Director, Ryan set the precedent for the home-baked appeal of Mango Languages’ product, as each language course component is intentionally crafted from scratch.

As Business Development Strategist, Ryan works closely with Co-Founder Mike Goulas to identify big opportunities, design new business models, create prototypes, evaluate strategic partnerships, promote new customer experiences, and to develop a path of how the company can bring these opportunities to market. A true pioneer, Ryan thrives in the realm of possibilities and is passionate about providing his team with creative latitude, empowering employees to innovate in real time.
