Two former Palantir executives have launched a startup called Dream. The company is building AI models that design buildings.
Dream came out of stealth on October 29 with $17 million in seed funding. Andreessen Horowitz led the round, with SV Angel, XYZ, and Zigg Capital also investing.
The founders are Andy Elder and Arjun Mathur. They were roommates at Stanford, where both studied computer science.
Both men then spent about ten years at Palantir. Elder led product design for a team of 800 people building software for U.S. defense and intelligence agencies. Mathur served as a senior vice president in the company’s commercial practice.
The pair started working on Dream early last year. Neither founder has a direct background in architecture.
Why Dream Is Targeting Construction
The founders were concerned by a problem in the U.S. building sector. Fewer buildings are built in the country today than a few decades ago, as development costs have climbed.
“We’ve gone from dial-up internet to superintelligent AI, but our ability to build the physical world around us has actually decreased,” Mathur told TechCrunch.
Dream wants to replace older tools used in architecture, engineering, and construction, often called AEC. These include Autodesk’s AutoCAD and Revit.
Mathur said architects and structural engineers still draw each part of their designs piece by piece in legacy software. “AI really plays no role in that equation,” he said.
How the Dream Model Works
A standard chatbot like ChatGPT can create an image of a building. But that image will not be structurally sound.
Dream says its model is based on real physics and construction standards. It was trained on more than 100 million square feet of building data from permit archives across the United States.
“Our model actually understands what’s within those walls. What materials are used, what the beams are made of, and how much weight they can support,” Elder said.
The company calls this approach “structural cognition.” Its designs account for internal systems such as plumbing and HVAC.
Dream is already selling its product to AEC professionals and developers. They use it to plan building designs and estimate total costs.
The founders say the platform is now in use on 10 active projects. These projects are in Texas and California.
Other startups are also bringing AI to building design. These include Motif, Snaptrude, and Arcol.
Elder and Mathur say Dream is the only company that has built a world model able to design whole buildings instantly. They say this sets the company apart from its rivals.
Kimberly Tan, a partner at Andreessen Horowitz, said the firm first invested in Dream more than a year ago. At that time, the company was only an idea.
Tan said she has been very impressed with the startup’s progress since then. “I have not seen anybody take the technical approach,” she said. “They’re doing everything based on their own models.”
