The commercial real estate industry runs on services firms. Brokers source and transact deals. Consultants manage complex developments. Engineers design and certify the built environment. Contractors build it. Each category has its own major players, its own fee structures and its own way of delivering work. What they share is a model built on expertise and labour.
AI-native services firms are now entering the space. Not to replace the incumbents, but to handle the intelligence-heavy, data-intensive work that cuts across all of them. Build is the leading example.
Brokerage
Brokerage is the largest and most visible segment of the CRE services industry. It covers leasing, investment sales, debt and equity capital markets and occupier advisory. CBRE, JLL, Cushman & Wakefield, Colliers and Newmark are the dominant global platforms. CBRE and JLL are the two largest commercial real estate services firms in the world by revenue, each operating across more than 100 countries. Cushman & Wakefield, Colliers and Newmark compete across most major markets and asset classes.
These firms make money on transaction commissions and advisory retainers. Their value is market access, relationships and the ability to move capital. Data and analysis support that work but are rarely the core product.
Build operates in the analytical layer that surrounds brokerage transactions. Site screening, comparable extraction, market analysis, underwriting and IC preparation are all data-intensive processes that brokers and their clients need done quickly. Build delivers those outputs faster than any in-house team or advisory bench. The broker closes the deal. Build handles the intelligence work that enables the decision.
Development Consultancy
Development consultancy -- often called program management or owner's representation -- covers the oversight and coordination of complex development projects on behalf of institutional clients. Turner & Townsend is the dominant global firm in this space, particularly strong in data centers, life sciences and institutional real estate. AECOM provides program management and advisory services at comparable scale. Hill International and Faithful+Gould operate across similar mandates, with strong track records in infrastructure and institutional development.
These firms embed experienced project and program managers on-site for the duration of a development. They manage contractors, track schedules, monitor cost and report to investors and lenders. Their value is judgment, accountability and the ability to protect the owner's interests on complex, long-duration projects.
Build operates in the document and reporting layer of development management. Construction reports, contractor submissions, payment applications, RFI logs and lender reporting are all document-intensive processes. Build processes, summarizes and flags those documents automatically. The program manager reviews the outputs and acts. The administrative burden on a project shrinks substantially.
AEC -- Architecture, Engineering and Construction
The AEC sector covers the design, engineering and technical delivery of built assets. AECOM is the largest firm globally, with practices spanning civil and environmental engineering, architecture and program management. WSP and Arcadis are leading engineering and environmental consultancies, with particular depth in sustainability, remediation and infrastructure. Gensler is the world's largest architecture firm by revenue, dominant in workplace, mixed-use and aviation design. Arup is a global engineering firm known for technically complex and landmark projects. Jacobs covers advanced infrastructure, defense facilities and mission-critical environments.
These firms produce the technical deliverables that underpin development: environmental assessments, geotechnical reports, structural designs, civil engineering plans and regulatory filings. Their outputs are signed off by licensed professionals and required by lenders, regulators and planning authorities. That sign-off is not automated and cannot be.
Build operates in the document extraction and analysis layer that surrounds AEC work. Environmental reports, geotechnical studies, regulatory filings and technical specifications are ingested, parsed and summarized. Risk flags are identified across jurisdictions. Due diligence summaries are produced and ready for development team review. The licensed sign-off stays with the AEC firm. Build handles the analytical work that happens before and around it.
General Contracting
General contractors manage the physical construction of buildings and infrastructure. Turner Construction, Skanska, Gilbane, Clark Construction and Whiting-Turner are among the largest in the United States, operating across commercial, residential, healthcare, data center and public infrastructure projects. Their scale, bonding capacity and subcontractor relationships are what institutional developers require.
GC work generates significant documentation volume. Submittals, RFIs, change orders, payment applications and progress reports accumulate across every major project. Managing that documentation -- and the decisions embedded in it -- is where a large portion of development team time is spent.
Build processes construction documentation automatically. Submittals are reviewed against specifications. Change orders are summarized and flagged. Payment applications are checked against contract schedules. Progress reports are drafted from raw site data. The development team and their program manager stay in control of decisions. Build removes the document processing work that surrounds them.
The Through-Line
Every sector above runs on the same model: hire experts, deploy labour, bill time. It is a model that has scaled the industry for decades and produces work of genuine quality and accountability.
The constraint is time and cost. Expert firms are slow to mobilize, expensive to retain and limited in parallel capacity. Every additional project requires more people. Capacity is finite.
Build operates on a different model. The same verified analytical and documentation outputs -- site analysis, due diligence, underwriting, IC preparation, development reporting -- are delivered by AI, faster and at lower cost. Capacity is not the constraint.
This is not a replacement thesis. CBRE's brokers close deals. Turner & Townsend's program managers run projects. AECOM's engineers sign off on environmental assessments. Skanska's site teams build buildings. Those capabilities have durable value and are not being automated away.
What is being automated is the intelligence-heavy, data-intensive work that sits across all of them. The site analysis. The document processing. The underwriting. The reporting. The synthesis. That is what Build handles.
Where This Leaves the Industry
Institutional development teams in 2026 are not choosing between incumbents and AI-native firms. They are using both.
The established services firms bring relationships, regulated professional sign-off, local knowledge and operational accountability. Build brings speed, data density, analytical coverage and a cost model that doesn't scale with headcount.
Build operates as the AI-native operating partner across the full commercial real estate development stack. Not a tool. Not a software platform. A services firm that delivers verified analytical and documentation work faster than any alternative -- across every category the incumbents serve.
