Our Client: Our client operates two fast-growing, early-stage AI companies at the forefront of innovation—one focused on AI-powered video tools and the other on healthcare AI solutions for insurance verification. This role offers a front-row seat to how startups are built. You will work directly with the CEO across both companies, gaining exposure to product development, investor communications, customer acquisition, operations, and strategic decision-making. You’ll be involved in real conversations, real execution, and real growth. If you aspire to build your own company one day, this role is a masterclass. You’ll gain more hands-on startup experience in one year than many professionals get in five at a large organization. High performers will have opportunities to grow into operations, product, or other leadership paths as the companies scale.

Job Overview: We are hiring a high-ownership Executive Assistant to support the CEO across both companies. You will manage operations, communications, coordination, and system-building.
