The LYTFOX Story


LYTFOX is the product of a unique partnership spanning the doctor- patient divide.

Sharon Feder
Founder & Board Chair

When Sharon Feder’s second son was born, he needed immediate surgery; the first of many. She managed his complex case with dozens of separate specialists, but they had no efficient way to be continually updated on the growing stacks of medical records—nor to effectively communicate with each other. A single overlooked symptom could have cost his life, or quality of life.

Her son needed an accurate, accessible, searchable summary of his complete history so all his doctors could be on the same page.

Sharon founded a company called Lynx Collaborative in 2003 that used medical professionals to organize health information and deliver it to patients, caregivers and providers—when and where they need it.



Michael Victoroff, MD
FAAFP, CI
President & CMO

Michael Victoroff practiced Family Medicine and Obstetrics for 30 years with the conviction that smart technology was needed to manage a growing mass of raw medical information. He was in the first group of practitioners to become board certified in clinical informatics—the specialty that oversees this challenge.

He brings a compassionate, ethical spirit to the patients and systems he works with. Michael joined Sharon in a fifteen-year effort of research and development. They interviewed users of medical information: patients, families, providers, administrators, payers, thought leaders, advocates, policy makers and technology experts. They stepped off the path of “easiest” technology onto a spiral of inventing and testing better solutions for the central communication challenge in healthcare: efficient presentation of enduring patient information.



David Kaysen, CEO

David Kaysen’s long experience in business and healthcare-related companies made him the perfect choice to lead a company with the goals Sharon and Michael had in mind. He immediately recognized the potential of their ideas and proposed a business model that would bring their innovations to a broad market. The result is LYTFOX, a company uniquely positioned to bridge the information chasm between patients and their providers
