A year in the life of a start-up can mean a great difference in fortunes, good and bad. We checked in with the founders of the six winners of Philadelphia Media Network's inaugural Stellar StartUps competition in 2016 to learn the most significant business development each experienced in the last year and the biggest goal for 2017.

Arcadian Telepsychiatry LLC, Fort Washington, Health Care winner

Accomplishment: "We have developed a program to address hospital readmissions for psychiatric patients," said Robert Plotkin, president and CEO of the company, which provides video-enabled mental-health services. "Four out of the top 10 reasons for readmissions are behavioral-health and substance-use disorders. Through the use of telepsychiatry, care coaches, and digital engagement tools, we can change the outcomes for many of those patients who would otherwise be readmitted."

2017 goal:  To launch its readmissions program with a regional health plan.
