Top SchoolEmanuel Jöbstl is a Vienna-based tech founder and CEO with 15 years of experience building B2C products, scaling communities, and shipping production-grade backend systems. He co-founded Authory and contributed to prominent open-source projects like Prisma, where his backend work touched ORM engines and GraphQL schema tooling, and to DlibDotNet on core C++/C# bindings. His background blends top-tier AI research at Carnegie Mellon with hands-on engineering—he's equally comfortable with differential equations for energy systems and low-level performance fixes in databases. As Head of Alumni and former Global Community Director at Sigma Squared, he pairs technical depth with community-building instincts to grow networks worldwide. Currently he leads Optima to simplify the energy transition, applying a unique mix of research rigor, product pragmatism, and a taste for memes and green tea.
