Skipping College to Solve Contractors' Biggest Estimating Bottleneck

Elle Yerushalmi is a high school senior and co-founder of Dimensions, an AI-powered estimating and measurement tool built for windows and doors contractors. Her mom is Lori Dennis, one of Los Angeles's top interior designers. Her dad is one of Southern California's leading luxury home builders. Elle is skipping college entirely to build alongside him. We cover how she identified the gap between a site visit and a quote as one of the most painful bottlenecks in residential contracting, how she's using Claude Code to build the frontend of the product, and what her post-graduation plan looks like when she can go full-time on job sites. We also get into the longer-term vision, including humanoid robots handling physical installation once the fleet-learning economics make it viable. For contractors, the most useful part of this conversation is the plain description of why the 2–3 day quote delay is a solvable systems problem, and what it actually looks like when someone decides to build the tool that closes it.
