Promise Robotics Signs D.R. Horton for 1,250 Homes, With a 16,000-Square-Foot Phoenix Factory Due in 2027

Promise Robotics, a Toronto company that runs robotic component factories for homebuilders, signed a multi-year agreement on 13 October 2026 under which D.R. Horton, the largest US homebuilder by volume, will use its factory-as-a-service model for more than 1,250 homes.

The company's press release was issued at 9:05 a.m. ET from Phoenix and calls D.R. Horton the first major US homebuilder on its platform. It does not name a home type, a city, a factory or a robot maker.

What the two reports say about the homes

The release leaves the homes unspecified, and the two trade outlets that covered the deal that morning disagree.

BetaKit, in a piece by Josh Scott, says the 1,250 are mostly single-story, single-family homes in the Phoenix area. The Robot Report, in a piece by Eugene Demaitre, says Promise focuses on townhomes of three to four stories. Both can be true of the company's wider business and still leave the question of what Horton is actually buying unanswered.

Detail	BetaKit	The Robot Report
Home type	Mostly single-story, single-family	Townhomes of three to four stories (company focus)
Location	Phoenix area	Edmonton, Calgary and Phoenix facilities planned
Factory	16,000 sq ft in Phoenix, production early 2027	Not sized

The Phoenix factory and the company's track record

BetaKit reports the Phoenix site is Promise's third factory and its first outside Canada, after Calgary and Edmonton, with manufacturing expected to begin in early 2027. Chief executive and co-founder Ramtin Attar called it the company's go-to-market facility in the US.

Promise says it makes interior and exterior walls, flooring, stairs and roofs today, and plans to add HVAC, plumbing, drywall and insulation. It uses off-the-shelf robots with its own tooling and software; The Robot Report says it works with KUKA industrial arms and describes the software as robot-agnostic.

BetaKit puts Promise's contracted volume at just over 2,500 homes for several homebuilders and its completed builds at more than 200, for customers including Brookfield, Hopewell and Mattamy. The company has 80 employees and aims for 100 by the end of 2026. BetaKit does not say whether the Horton homes are inside the 2,500.

The gap between 200 built and 1,250 promised for one customer is the number to watch. If the 1,250 are delivered over four years, the Phoenix factory would need to turn out about 312 homes a year; no source gives the term.

The one-day claim

The Robot Report says Promise claims it can build a two-family, two-story home with a basement and garage in one day, excluding electronics, windows and plumbing, against the two to three weeks the article says is typical. That is the company's claim, and the piece gives no throughput figure beyond that example.

It also quotes Brad Conlon, D.R. Horton's senior vice president for strategic growth and innovation, who said Promise's integrated platform "gives us a new capability." For other robotics companies we have covered, see FieldAI's reported $10 billion term sheet and MMI's Symani microsurgery robot.

Neither Promise nor D.R. Horton has disclosed financial terms, the length of the contract, the delivery schedule, the Phoenix investment or whether the deal is exclusive. Manufacturing in Phoenix is expected to begin in early 2027.
