About Chiefly

A letter from our founders

We started Chiefly because Mark’s wife was a chief resident who spent months scheduling in Excel. We didn’t intend to start a company. Honestly, it started as a selfish endeavor to give Mark more time with his wife.

What started as a side project in 2024 quickly turned into a realization: GME needed a better scheduling platform, one designed with the scheduler and residents in mind.

Today, we have an all-star team of technologists tackling this problem. They’ve previously worked at Google, Square, Jane Street, Uber, Fleetline, Quest Analytics, and PwC. For our clients, that means we ship features quickly and get in the weeds to understand your program’s unique schedule.

“Your team is also always so ahead of new features that we often hear of improvements to the system before even getting a chance to bring up how useful they would be for us!”

It’s a pleasure to be building Chiefly alongside each of you.

Sincerely,
Mark & Dan
