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

Andy Elder and Arjun Mathur were Stanford roommates who both studied computer science before spending a decade at Palantir. Elder led product design for a team of 800 people building software for U.S. defense and intelligence agencies, while Mathur served as a senior vice president in the company’s commercial practice. When the friends decided to build a startup early last year, there was no question they would do it together.

Despite having no direct background in architecture, Elder and Mathur were troubled by a growing problem: fewer buildings are constructed in the U.S. today than a few decades ago, as development costs have surged.

“We’ve gone from dial-up internet to super intelligent AI, but our ability to build the physical world around us has actually decreased,” Mathur told TechCrunch.

Believing AI can boost productivity across the architecture, engineering, and construction (AEC) industry, they set out to build Dream, a startup developing world models that automate building design and engineering. Dream has emerged from stealth with $17 million in seed funding led by Andreessen Horowitz, alongside other backers including SV Angel, XYZ, and Zigg Capital. The startup aims to replace cumbersome, outdated AEC tools like Autodesk’s AutoCAD and Revit.
