CONSTELLATION HOMEBUILDER SYSTEMS ANNOUNCES STELLA AI - THE PURPOSE-BUILT AI AGENT DELIVERING INSTANT, DECISION-READY INSIGHTS FOR HOMEBUILDERS

Constellation Software Inc.'s Constellation HomeBuilder Systems, the largest provider of homebuilding software solutions and services in North America, has launched Stella AI, an enterprise-grade artificial intelligence agent for homebuilders. Built for executives and front line teams alike, Stella AI blends industry-specific intelligence, data security and integration with builder workflows.

Stella AI gives builders immediate visibility into market trends, performance shifts and opportunities for improvement by surfacing insights from BuilderMetrix -- Constellation's proprietary real-time data, analytics and benchmarking platform. BuilderMetrix features a robust homebuilding data set, which includes aggregated and anonymized financial and operational data from live builder ERP systems and other third party data that a builder may subscribe to.

"Constellation's launch of Stella AI marks a turning point for our industry," said Ty Brewer, chief digital officer at HistoryMaker Homes. "Most builders are just beginning to explore AI, but Constellation is already shaping what the future will look like, with practical, builder-ready tools that will help homebuilders unlock efficiencies and gain a competitive edge."

"We've been working closely with builders to bring Stella to life," said Bob Swainhart, vice-president, enterprise solutions, at Constellation HomeBuilder Systems. "While every builder's needs are different, the goal is the same: gain efficiency, improve decision-making and stay competitive -- and Stella is built to support that."

AI built for the realities of homebuilding

Stella AI is not a generic chatbot. It is a purpose-built homebuilding intelligence engine that helps builders:

• Surface clear insights sourced from robust homebuilder and industry data;
• Get complete visibility across communities, divisions and time frames to spot cost overruns, schedule risk and margin erosion sooner;
• Compare performance instantly across divisions, communities, time periods in seconds -- and benchmark against anonymized industry peers;
• Get immediate answers to operational and executive-level questions without digging through or manually creating reports.

"Stella AI transforms how builder teams operate," continued Mr. Swainhart. "What might take a purchasing agent hours across disparate sources can now be answered in seconds. Builders get both speed and confidence with insights backed by the same trusted data foundation they rely on today."

Constellation will showcase Stella AI at the International Builders' Show in Orlando, Feb. 17 to Feb. 19, 2026, booth S7049. Special introductory pricing will be available at the show.
