Alexander Groth is the CEO and co-founder of Cityweft, a platform that provides structured, interoperable 3D city models to help AEC professionals work more efficiently with geospatial context. He has a background in physics from UCL and previously worked in management consulting, where he focused on commercialization strategies for clients in the industrial sector.
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.
