Ex-Palantir execs launch Dream with $17M from a16z to build AI world models for construction

Andy Alder and Arjun Mather, former Palantir colleagues, launched Dream, a startup building world models that automate building design and engineering for the architecture, engineering, and construction industry. Dream emerged from stealth with $17 million in seed funding led by Andreessen Horowitz, with SV Angel, XYZ, and Zigg Capital also participating, aiming to replace legacy tools like Autodesk's AutoCAD and Revit. Its model is trained on more than 100 million square feet of building data from U.S. permit archives and is already deployed across 10 active projects in Texas and California.
