about

Jonathan Ronzio is a builder, creator, and adventurer who refuses to be put in a box. As an entrepreneur, endurance athlete, musician, award-winning filmmaker, best-selling author, and speaker, his career is a testament to the idea that you don’t have to choose just one path—you can do it all.

Jonathan is the Co-Founder & CMO of Trainual, a top-ranked SaaS company that has redefined how businesses scale. Since launching Trainual in 2018, he has blended storytelling with bold, unconventional marketing to build a category-defining brand while winning over tens of thousands of businesses, including the Phoenix Suns and Mercury, IRONMAN, and Chick-fil-A.

But Jonathan’s entrepreneurial journey started long before Trainual. At just 11 years old, he started working with his brother to build a video production company that grew into the largest national amateur sports video provider. A decade-long hustle and exit led him to create an adventure media agency, producing award-winning films and content for some of the world’s top outdoor brands. Whether in media, marketing, or SaaS, his talent for telling great brand stories and creating demand has been a common thread.

Outside of business, Jonathan is driven by an insatiable curiosity to push limits—physically, mentally, and creatively. He has summited some of the world’s highest peaks, like Kilimanjaro and Pico de Orizaba, taken on grueling ultra-endurance events such as the 29029 Everesting Challenge and running the Grand Canyon Rim to Rim to Rim, and completed the NYC, Boston, and Antarctica Marathons. He thrives at the edge of comfort, where resilience meets growth, and he brings that same mindset to everything he does.

A lifelong musician, Jonathan is also the frontman of Ronzio, a Boston-based band blending 90s-inspired alt-rock with elements of pop-punk, folk, and even hip-hop. He’s written music with Grammy-nominated artist Montell Jordan and continues to pursue his passion for storytelling through songwriting and live performance.

His creative range recently extended into authoring a best-selling children’s book, Sprocesses—an inventive take on entrepreneurship for kids.

Despite the relentless pursuit of business success, adventure, and creative expression, Jonathan remains deeply committed to what matters most—his family.

He lives just south of Boston, MA with his wife, Alex, their son, Chase, two rescue pups, and a Bengal cat, embracing the everyday joys that balance his high-energy lifestyle.

Jonathan’s life is proof that you don’t have to choose one career, one passion, or one identity. You can build, explore, create, and inspire—all at once.
