Opusense AI automates field report writing for construction field inspectors. Instead of typing up notes at the end of the day, inspectors can now walk a site, speak observations aloud, snap photos, and let our AI assistant generate a detailed, organized report on-site and in real time. Combined, the founding team has over 15 years in the construction industry. Writing up these field reports used to take up at least 20% of the week. With Opusense, we cut that time by 5x. Our team combines deep construction experience with technical expertise, Roya has a PhD in civil engineering, and Michael has worked at multiple construction tech startups. Why hasn’t this been done before? Construction is slow to adopt new tech, and reporting is messy, photos, voice notes, and field notes all live in silos. Turning that into a clear, structured report requires real insight into how inspectors work and what clients need. Only now, with advances in AI, can we process unstructured data adequately to generate high-quality reports in real time. The opportunity is massive. Every inspection firm and contractor is struggling with documentation. Manual reports slow them down, create inconsistencies, and delay handoffs. We believe AI can do this better, and Opusense is proving it.

Structured AI understands building codes, standards, drawing, and project requirements to generate and update the technical documents that normally take weeks to complete.

At Resolve we’re building the future of collaboration and review for the construction industry. Today, Resolve helps bridge the communication gap between people who operate buildings and those who design and build them. We've built the most robust application for collaboratively reviewing complex facilities on the web and on wireless VR devices like the Oculus Quest. Our customers love it because it just works even with complex 3D building models. From data centers to cutting-edge biopharma facilities, Resolve provides a collaborative virtual environment for operations & maintenance teams to review and interact with 3D building models at full scale - decreasing late stage changes during the construction process and delivering a safer, more easily operable building. Our customers' facilities contain a multitude of complex systems which require careful coordination and review to ensure the building is completed on time and within budget. To prevent rework and increased building maintenance costs, Resolve fixes the broken system of screen-sharing 3D models and 2D floorplans with the operations teams that inherit the building and, instead, gives them easy access to their 3D building models before concrete is poured.

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. Brian and William met at Carnegie Mellon as engineers and separately had their own frustrating new construction experiences. Brian ran a tech-enabled homebuilding factory and found the design iteration process to be a massive bottleneck, while William built ground up homes in Texas and had a similar frustration. 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.

City building departments are understaffed and overworked. Meanwhile, builders lobby to remove power from building departments. Because building departments are usually the only profitable/self-sustaining branch of a local government, this is problematic. Permitify allows city build-plan reviewers to 10x their productivity covering the labor shortage, reducing the time required to issue a building permit, and allowing the city government's only profitable branch to stay intact.
