Former Palantir execs launch Dream with $17M to build AI world models for construction

Former Palantir executives Andy Elder and Arjun Mathur have launched Dream, a startup developing AI world models trained on over 100 million square feet of building data to automate architecture and engineering design. The company emerged from stealth with $17 million in seed funding led by Andreessen Horowitz, aiming to replace legacy tools like AutoCAD by generating structurally sound building designs that account for internal systems like plumbing and HVAC.
