At Innovation Depot, we believe some of the best startups are born from deeply personal experiences, and the story behind Prismm is no exception.
In this episode of Mile-A-Minute, we walk and talk with sisters Martha Underwood and Shella Sylla, the powerhouse duo behind Prismm, a digital vault designed to simplify one of life’s most complex moments: transferring wealth and information after a loved one passes.
It all started with a scare. When their father fell off a roof during Hurricane Irma and was rushed to the hospital, their mother was left scrambling for critical documents; health directives, insurance details, and more. That moment revealed a massive gap in how families manage and access end-of-life information. Prismm was built to close that gap.
Today, Prismm is changing the game for banks, financial institutions, and wealth advisors by providing a secure, accessible platform to store and transfer essential documents. As Martha says in the interview, “Love for my parents inspired this—and I never want anyone else to feel that helpless in an emergency.”
The best part? This is a true family business. Martha and Shella aren’t just co-founders; they’re sisters. “I get to tell her like it is,” Martha laughs, “and she can’t do anything about it because she’s stuck with me.”
Their mission is simple but powerful: make hard conversations easier and help families plan for the future with confidence.
💬 “Prismm is the vault built for the next generation, powered by the wealth of the last generation.”
Watch the full conversation below to hear more about their story, meet their CTO Chris, and get a behind-the-scenes look at how Prismm is building the future of digital legacy.
