Semion Sobolevski is the founder of Cityweft. With a background in AEC software development and a deep understanding of the challenges in early-stage construction planning, Semion began building the platform that makes contextual urban data accessible and actionable. Cityweft empowers the construction and design industries with seamless access to high-quality 3D city models and geospatial insights.
In 2025, architects and urban designers still face a basic, frustrating question at the start of every project: where is the context model? Despite the explosion of AEC tools and digital workflows, site context data—whether GIS or 3D—remains patchy, low quality, or locked in unusable formats.
In this talk, we explore why this foundational step in design has been overlooked for so long, and how improving it can unlock better, faster decision-making across the AEC stack. He’ll share how Cityweft is addressing the problem by making high-quality, geospatially accurate context models accessible in clean, interoperable formats—so that the industry can stop wasting time assembling the basics, and start designing.
