Meals and conversations: Free meals, snacks, and drinks to keep us fueled, but more importantly: they bring people together and foster community.

Wellness for every body: We’re proud to offer inclusive health care such as hormone treatments, gender-affirming surgery, therapy, family planning, and more.

The time you need: Our flexible PTO policy means every employee is encouraged to take the time they need now to keep doing great work, long term.

Family-friendly benefits: Fertility treatments, primary and secondary parental leave, sleep coaching, house cleaning for new parents, and more.

Be well, be you: Get free, comprehensive medical, dental, and vision benefits, plus a monthly fitness stipend and mental health resources too.
