Jakub Siska

Director, Forensic Technology Solutions Leader, PwC Switzerland

Jakub Siska is a Director at PwC in Zurich, where he helps global clients navigate the difficult ground where technology, AI, and complex legal and regulatory issues meet. He often takes the role of technical lead on cross-border matters, drawing on years of hands-on infrastructure work and AI-enabled analytics to build secure, scalable solutions for clients facing regulatory and litigation pressure.

Much of Jakub's work involves close collaboration with leading law firms across different jurisdictions, where he designs and delivers the technology behind high-stakes matters. He has run complex eDiscovery programs that speed up collection, analysis, and disclosure across complex, varied datasets—keeping both risk and cost under control along the way.

Over more than a decade, Jakub has led technically demanding programs for some of Switzerland's best-known enterprises, coordinating PwC teams and partner law firms across borders. That work has ranged from building bespoke client-side data-hosting environments to setting up end-to-end collection and analysis pipelines, always with an eye on local data protection rules and the practical realities each client faces.

Colleagues and clients know him for turning genuinely complex technical challenges into practical, compliant results—with the kind of solid governance, clear documentation, and dependable delivery that holds up even in the most tangled, multi-firm engagements.
