Jakob Zeise CEO & Founder | Zeise Digital As founder and CEO of Zeise Digital, I lead a growing app and web development agency based in Germany, specializing in cross-platform mobile development with Kotlin Multiplatform Mobile (KMM). My vision: delivering high-quality, native-performance apps from a single codebase, helping clients reduce development time and costs without compromising on user experience. My role spans the full spectrum of running a technology company. On the business side, I drive strategy, client acquisition, contract negotiations, and financial planning. I work directly with clients across industries including education, wellness, gaming, and services to translate their needs into scalable digital products. From concept to app store launch, I ensure every project meets both technical standards and business objectives. On the technical side, I make key architecture decisions and stay hands-on with development. My expertise covers Kotlin Multiplatform, Compose Multiplatform, React, Java, Supabase, and modern AI services. I design systems built to scale, with clean backends, secure authentication, and seamless experiences across iOS and Android. I also focus on team building and leadership, managing a team of developers and designers with a flat hierarchy that encourages ownership and direct communication. Beyond client projects, I continuously explore new technologies and business opportunities to keep Zeise Digital at the forefront of mobile development. Tech: Kotlin Multiplatform, Compose Multiplatform, React, Supabase, AI Integration Languages: German (native), English (fluent)
