> Its world model uses U.S. permit records covering more than 100 million square feet, and the company says its product is active on 10 projects in Texas and California.

Dream, a startup founded by former Palantir executives, raised $17 million in seed funding to develop AI for building design, targeting parts of U.S. construction planning.

The seed round was led by Andreessen Horowitz, with SV Angel, XYZ and Zigg Capital also investing. Dream’s co-founders, Andy Elder and Arjun Mathur, were Stanford roommates and both studied computer science before spending a decade at Palantir. Elder led product design for an 800-person team building software for U.S. defense and intelligence agencies. Mathur served as a senior vice president in Palantir’s commercial practice.

Dream is developing software for architecture, engineering and construction work, where it hopes to automate portions of design and engineering. Its world model was trained on building data from U.S. permit archives covering more than 100 million square feet. The company says the system uses physical requirements and construction standards to generate designs.

Dream calls the method “structural cognition.” Its output is meant to account for what lies inside a building, including plumbing and heating, ventilation and air conditioning systems. Elder said the model can identify materials and the composition of beams, and estimate the weight they can carry. The founders argue that a general-purpose language model can produce a building image without showing whether the design is physically workable.

The company has started selling the product to industry professionals and developers, the founders say. They said users apply it to early building concepts and broad cost estimates. The software is now in use on 10 active projects across Texas and California.

Dream is positioning its software as a way to change a design process that Mathur said still involves professionals assembling plans one element at a time in older programs, with little role for AI. The company aims to automate tasks currently done with Autodesk’s AutoCAD and Revit.

Dream is entering a field with other startups also applying AI to design tools. Motif, Snaptrude and Arcol are among the companies working to update architecture, engineering and construction software.

Elder and Mathur were drawn to the business by a concern that fewer buildings are being constructed in the U.S. than decades ago as development costs have risen. Mathur said the company sees a widening gap between rapid AI progress and the ability to build in the physical world.
