What employees are saying

"I honestly find it hard to believe I'll ever find another company as flexible and employee-focused as this. They've made it almost impossible for me to ever leave, in a good way! Some other notable things I really appreciate: no meetings allowed on Wednesdays, only deep, focused work. And every other Friday is "Wellness and Creative time," where you can work on your own projects, read a book, go for a hike, clean your house, sleep all day – whatever you need to stay happy and mentally healthy."
