How we work Remote-First Company: our working hours follow a 2 hour window from 9 am - 6 pm CST Driven by an ambitious mission: we're reinventing how we should think about wellness from the first 1,000 days to the last Shape what we build, not just how we build it : we prioritize experimentation with taking ownership, and moving fast No hidden agendas : we operate with full transparency because when everyone's working from the same honest picture, you spend less time on politics and more time on impact High standards, human culture: we hold ourselves to a high bar and do it alongside a team who can laugh at themselves and make the hard days genuinely enjoyable Our Values Learn fast, be better (root cause analysis) What that looks like: When a stakeholder gives constructive criticism to a test result, instead of just apologizing and moving on, you dig into why it happened and update the process so the feedback is not received again. Be relentlessly resourceful (be scrappy) What that looks like: When a customer asks a question about our science, you you spend time digging through our docs and filtering through Slack for previous replies before pinging the team. You also know not to burn a whole day stuck, so you ask for help with a clear summary of what you've already tried. Think like an owner (ownership) What that looks like: When you notice customer engagement is dropping, you don't shrug it off as another team's problem - you flag it, dig into the numbers, and bring a fix, because you're hungry to see the whole company win, not just your own tasks hit their targets. Act with honesty and empathy (radical candor) What that looks like: When a colleague shares an idea that carries real risk, challenge in the moment and do it with kindness - don’t vent about it afterward in a side conversation. Delight people by anticipating their needs (create raving experiences) What that looks like: You put yourselves in the shoes of the customer or collaborator before presenting an idea, process, or proposal. Think ahead about what their pain and gain points are, and curate your communication to address their needs.
