Proptech Startups funded by Y Combinator (YC) 2026

Inviscid AI builds physics-informed AI solutions that transform how buildings and data centers operate. By combining real-time IoT sensor data with computational fluid dynamics (CFD) modeling, we create digital twins that simulate building performance in real time and autonomously optimize operations. Our platform optimizes airflow patterns and ventilation strategies to eliminate dead zones, improve air distribution, and reduce the load on mechanical systems. On the energy side, we minimize HVAC power consumption, reduce cooling costs, and lower overall operational expenses while maintaining optimal thermal comfort and indoor air quality. Beyond immediate operational efficiency, we optimize equipment scheduling and maintenance cycles by predicting system behavior under different conditions, allowing facilities managers to proactively address issues before they become problems. Our physics first approach ensures that we're not just optimizing against historical patterns, but optimizing based on a deep understanding of how air, heat, and energy actually move through your building, enabling us to find solutions that traditional rule-based or purely data-driven systems would miss.

Scout Out helps residential contractors estimate jobs faster and submit clearer, more competitive proposals. Today, every contractor bidding a residential remodel or rebuild has to manually interpret plans, calculate material and labor quantities, and assemble a proposal from scratch. The process is slow, inconsistent, and expensive — and small differences in scope often decide who wins the job. ScoutOut automates this workflow. We use computer vision trained on residential building plans to generate structured material and labor takeoffs, which contractors can review, customize, price, and turn into professional proposals. Instead of starting from zero on every bid, contractors start with a standardized, high-quality estimate they can trust. The result: contractors bid faster, price more consistently, and submit clearer proposals — helping them win more residential remodeling and contracting jobs with less overhead. We’re starting in Los Angeles, working closely with residential contractors on remodels and post-fire rebuilds following the Palisades and Eaton fires.

Goldbridge is building the financial operating system for the largest asset class in the world – real estate.

Goldbridge solves this problem by creating the first AI-powered banking platform for real estate owners.

ArchiLabs is building an AI co-pilot for architecture. Instead of spending hours on tedious tasks, architects can 10x their design speed with simple AI prompts.

However, at the time, there wasn't an easy solution to the many pain points in the design process. As AI reasoning models improve, Brian and William realized that there was a massive opportunity to fix the long-tail of frustrations and build a new construction design experience by fine tuning existing models, becoming bigger than Autodesk, the $60B company in the space.

With Ancana, you can own a 1/4 or 1/8 share of the home and split expenses with the other co-owners. If you buy a 1/4 share of a home, you have access to it for 3 months of the year. For each property we set up the investment trust, find qualified co-owners, and handle the entire real estate purchase transaction. Costs are split amongst the co-owners, and we take care of the furnishing and ongoing property management. We accomplish this by creating an investment trust for each property and dividing it into individual, purchasable shares that represent ownership in the property. We furnish each home and find and vet the co-owners. Once all of the shares of the property are sold, we retain no ownership stake in the property and transition into the role of property manager, ensuring the home is well maintained and handling any issues that arise. Unlike a timeshare, Ancana owners own a real asset (the property) versus a block of time. If you decide you want to sell your share, you are free to do so at any time, either through us or on the open market, and capture any appreciation the property has accrued.
