Belief in the mission: We will have served 100 million patients by the end of 2035 and we transform the life of most patients who join. We have a lot of work to do. We are obsessed with our patients and are dedicated to the mission.Unwavering integrity: We are at the frontier, so we often live in ambiguity with no trodden path. When we can’t look to others for guidance, we must maintain impeccable ethics and unwavering integrity.Only the paranoid survive: Bad sh*t is coming. By joining us, you’re choosing to sail straight towards the storms with unhesitating conviction. However much we’ve already done, however far we’ve already come — it’s still Day 1 and all our work is ahead of us.If we’re average we fail: We are only interested in “insanely great”, a focus on the quality of our execution that in everyday life would be considered pathological. We have a dedication to excellence and reject incompetence.Commitment to candor: That which can be destroyed by the truth should be. You get full transparency from the company and the company expects full transparency from you. We never say anything about someone that we wouldn’t say to them directly. We give feedback with love and do not need to protect people from fleeting physical sensations.A maniacal sense of urgency: We execute at an intensity that most people think is impossible. Speed is critical and we need things done yesterday. We all work very hard and in such a competitive world there really is no other way to win.Enduring frugality: We are frugal. We hate being wasteful and we are antiluxury. A culture of cheapness keeps us young. We spend our cash wisely & carefully — in a way that would make our grandmas proud.Bulldozing barriers: The world is malleable and we shape it. We truly believe this and act accordingly. We are relentlessly resourceful and are at the mercy of noone but ourselves. You’ll be shocked how capable you are and how much you can achieve.Keep your head down: We’re boring people doing exciting work. We don’t chase shortterm status — we ignore shortterm dopamine hits and focus on what matters. Outsiders will underestimate us and we revel in that.The power of focus: We live in a world of power laws and we cannot overestimate the unimportance of practically everything. Know your One Thing, and nail it.Compensation: $80k$120kyear (cash comp + equity)
Vacation: generous timeoff with a yearly minimum
Remote: our team is fully distributed across the world and functions fully remotely
Healthcare: comprehensive medical insurance
Professional development: budget for books, courses, coaching ($600yr)
Personal wellness: budget for gym, health apps ($600yr)
Equipment: WFH gear provided as needed, inc Macbook (>$1000)
