Already live with enterprise customers and thousands of users, and now moving into the next phase of growth. What’s interesting here: You’re building the core mobile experience, not supporting it; Real users, real usage, real scale (and growing fast); Early enough to shape the product and technical direction; Backed by a leadership team that’s built trading systems and scaled startups before. Environment: Low ego, high ownership.
