LeanCon is an Israeli AEC startup developing what it calls the first AI-powered pre-construction engineering team. The platform turns the most complex phase of building, pre-construction planning, into a fast, data-driven process: where traditional planning can take months and cost upward of $2M per project, LeanCon generates detailed projections on cost, schedule, logistics, and construction methods in roughly seven minutes at near-zero cost, letting general contractors and developers evaluate far more project opportunities. LeanCon's platform is already used on more than $650M in active development projects across New York. In early 2026 it closed a $6M seed round led by Ibex Investors, with participation from Fusion VC, Newman Architects, TCA LA, Connecticut Innovations, Siegel Capital, and angels including former Autodesk AEC VP Phil Bernstein.
