Leonard Petter is a Berlin-based founder and software engineer with a decade of experience building B2B SaaS products and AI-driven solutions. As co-founder and CEO of AirType and previously of Luup and Joice, he blends product-led entrepreneurship with hands-on full-stack engineering across sustainability, HR-tech, and energy domains. His background at the Hasso Plattner Institute — where he helped build the first incubator and co-created a neural nets course with 10k+ learners — reflects a strong mix of technical depth and program-building instincts. Leonard moves comfortably between prototyping user-facing React apps and backend services in production, often applying design thinking to reduce friction in document-driven processes. He has a track record of turning interview-driven insights into pragmatic SaaS offerings for SMEs and brings a rare combination of teaching, startup incubation, and execution experience. Based in Berlin, he pairs academic rigor from HPI with entrepreneurial grit to ship impactful, sustainability-minded products.
