This Research Note examines investment trends across the Architecture, Engineering & Construction (AEC) lifecycle, drawing on our Startups in Smart Buildings Report H1 2026, which analyzed early-stage AEC startups developing AI-powered platforms for workflows, productivity and evidence-based decision-making.
A Software Landscape in Transformation
The AEC software landscape is being reshaped by a wave of early-stage startups applying artificial intelligence (AI) to some of construction’s most stubborn problems, fragmented workflows, labor-intensive processes, and decisions made without good data.
Our latest Startups in Smart Buildings report identifies 137 companies applying digital twin and AI technologies across every stage of the building lifecycle, from architecture and design through engineering, construction, and operations.
Investment: Almost Double Last Year’s Total, in Half the Time
Capital is flowing into the category at pace. We identified 46 funding rounds for AEC software startups in H1 2026, making it the highest-funded segment in the smart buildings startup sector this year.
The acceleration is striking. Across the whole of 2025, we tracked 31 funded AEC software startups raising a combined $318 million. In just the first six months of 2026, 46 startups have raised $616 million, nearly double last year’s full-year total.
The investor base spans Y Combinator and venture capital firms through to strategic stakeholders across the building lifecycle. The established AEC software vendors, Nemetschek, Autodesk, Trimble, Hexagon, Bentley, and Procore, are the primary strategic investors, while venture capital firms are also deploying heavily.
Deal sizes ranged widely. At the top end, Autodesk invested $200 million in World Labs, a frontier AI spatial intelligence startup. Stockholm-based Endra raised a $50 million Series A to automate design work for mechanical, electrical, and plumbing (MEP) engineers. The majority of rounds, however, were pre-seed and seed investments, consistent with how recently most of these startups were founded.
M&A: Strategic Buyers Move Fast
Merger and acquisition (M&A) activity has intensified over the past two years as AEC software firms buy AI-powered startups to augment their portfolios. We identified 7 transactions in the first half of 2026, all by strategic buyers in the AEC software sector, up from 3 deals across the whole of 2025.
Memoori View
We expect investor interest in AEC software startups to continue throughout 2026. AI-enabled workflows across design, engineering, pre-construction, and physical construction are delivering better decision-making for every stakeholder in the building lifecycle, and AI lends itself particularly well to pre-construction, where complex processes sit between design and breaking ground.
There is a caveat. Most funded AEC startups are targeting point solutions. These fix specific operational failures, but they do not address the larger challenge: digital transformation across the entire AEC lifecycle.
That said, we are seeing the beginnings of a convergence trend. AEC software vendors are investing in building operations, while real estate and facility operations stakeholders are investing in design, engineering and construction startups, and the traffic is moving in both directions.
The standout deal this year is Autodesk’s acquisition of building operations software vendor MaintainX in May 2026. Founded in 2018 and headquartered in San Francisco, MaintainX provides an AI-powered computerized maintenance management system (CMMS) and enterprise asset management (EAM) platform. The $3.6 billion purchase price values the company at roughly 18 times projected 2027 revenue of $200 million, a clear signal of how much strategic buyers will pay to bridge construction and operations.
The traffic flows the other way, too. In 2025, JLL Spark, the strategic investment arm of global real estate services firm JLL, backed architectural startups Acelab and qbiq, while Tishman Speyer invested in Bobyard, developer of an AI platform reshaping construction estimating.
Schneider Electric, known for energy management and building operations software, has also moved upstream. Its venture arm, SE Ventures, participated in the September 2025 seed round of Temelion, a French startup targeting how building engineering firms manage pre-construction workflows, and in June 2026 continued its backing of Higharc, “the homebuilding AI company for the full design-to-construction lifecycle.”
These cross-lifecycle investments could provide the momentum for key stakeholders to finally tackle digital transformation across the building lifecycle, from design all the way through to operations.
