Who You Are

• You're a Dog. You've been underestimated, gone through struggle, and never stopped running.
• You have a chip on your shoulder and enormous drive.
• You look at Stripe, Deel, and Flexport all punting on compliance and think: good, that means the opportunity is ours.
• Hunger beats pedigree. Early stage is in your bones.
• You've built things where there's no playbook and nobody handing you the answer.
• You define the problem instead of waiting for instructions.
• You own it end to end.
• Give you a goal and you figure out your own path.
• Small team, global surface area — everyone owns a domain that would be a full team at a larger company.
• No one tells you how.
• You believe speed and accuracy are both possible.
• We're building a complex product that requires robustness and 100% uptime, and we have to build at our customers' pace.
• Mov Speed and don't break things. Both.
• Being in the room is a feature, not a cost.
• Five days in SF isn't a policy, it's how the work gets done.
