Strategy & Operations, Founder's Office

Our vision is a world where every patient feels cared for and every doctor has the capacity to care. Our mission is to end the second shift.

For most doctors in Latin America, the workday doesn't end when the last patient leaves. A second shift starts on WhatsApp: patient messages, rescheduling, follow-ups and payments, often late into the night. Leona takes that shift off their hands. Our AI assistant reads and answers patient WhatsApp threads, books appointments, and is expanding into billing and payments for medical practices. Today, doctors across 28 specialties in 14 countries use Leona to manage relationships with their patients.

We're building toward a future where patients feel cared for between visits, not just during them, and where doctors get their evenings back, while increasing their earnings.

With bases in San Francisco and Mexico City, our team brings together years of experience scaling companies like Uber, Rappi, and Modern Fertility across the US and Latin America. We're backed by a16z, General Catalyst and Accel, along with a remarkable group of angels including the founders of Nubank, Rappi, and Maven Clinic.

Leona is growing too fast for the founders to be in every room. You'll work alongside our CEO, Caroline Merin, as her right hand and report directly to her. You'll see everything she sees, decide what truly needs her attention, and handle the rest yourself. The core of the role is internal operations, investor relations, partnership management and special projects. Your job is to help Leona move faster and think more clearly, and to free the CEO to do the work only she can do. You'll help make the call, and then you'll own making it real. You won't be writing recommendations for someone else to carry out.

The team is small. Caroline and her cofounders currently run finance, HR, investor relations, and many parts of internal operations themselves. This role will own many of the day-to-day systems that keep the business running. The goal is both to improve how Leona makes decisions and to keep Caroline and her cofounders out of work that should no longer depend on them.

This role is ideal if you want to start your own company one day. You'll learn how a venture-backed company is built from Seed and beyond, by doing the work rather than watching it. If you want structure handed to you or a predictable week, this isn't the role for you.
