Construction is one of the world's largest industries - and one of its least productive. While economy-wide labor productivity in the US more than doubled between 1970 and 2024, construction labor productivity fell by roughly 30% over the same period1construction labor productivity fell by roughly 30% over the same period. That divergence underpins a new class of strategic investors - none more instructive than Toronto-based Hazelview Ventures.
Unlike generalist technology funds placing speculative bets, Hazelview Ventures backs buildtech from the inside. As the venture arm of Hazelview Investments - a firm with a $13.4 billion real estate development pipeline - it tests the technologies it funds directly across its own portfolio of properties and construction projects. The result is a tightly focused investment model that treats productivity constraints not as an abstract market thesis, but as an operational problem demanding concrete solutions.
A Declining Baseline: Why Construction Productivity Is the Central Problem
The productivity crisis in construction is well documented and persistently severe. Since 1965, labor productivity in US construction has fallen at an average pace of 0.6% per year, while productivity in the wider economy has grown at about 1.6% per year, according to Goldman Sachs Research2Goldman Sachs Research. Over the long horizon, construction labor productivity is virtually flat between 1964 and 2024, whereas labor productivity in the economy overall rose by a factor of three.
The causes are structural: fragmented supply chains, project-by-project procurement models, persistent data standards barriers, and a workforce slow to absorb digital tools. The US construction industry had the lowest rate of business technology use among all industries as of a 2020 study. Meanwhile, between August 2023 and July 2024, the construction industry averaged 382,000 monthly job openings, signaling chronic labor shortages3signaling chronic labor shortages that technology is increasingly expected to fill.
The scale of the opportunity matches the problem. The global construction market is projected to reach $19.59 trillion by 2032, and every day until 2050 the industry must build 13,000 structures to accommodate an expected urban population of 7 billion people. Investors tracking that backdrop are no longer asking whether buildtech will matter - they are asking which technologies will scale.
Hazelview Ventures: The Integrated Investor Model
Hazelview Ventures4Hazelview Ventures launched in 2021 with a differentiated mandate: invest only in early-stage PropTech, BuildTech, and CleanTech companies whose solutions can be tested and refined within Hazelview's own operational ecosystem. The fund is led by co-founder Roger Poirier, a chartered financial analyst with three decades of capital markets and M&A experience.
The logic is strategic. As Poirier has stated, Hazelview's position as one of Canada's larger property managers means that "if a solution makes sense for us, we would expect it would make sense for others as well." In practice, this gives portfolio companies a paying enterprise customer and a real-world testing environment from day one - reducing the commercialization risk that typically kills construction technology startups before they reach scale.
The fund operates at seed stage, with an average seed round size of $2.6 million across four investments. That capital-efficient model is backed by Hazelview Investments' integrated platform5Hazelview Investments' integrated platform, which provides strategic support, enterprise access, and direct implementation pathways that cash alone cannot replicate.
The Portfolio: Three Technology Bets on Productivity
Hazelview's buildtech investments cluster around three distinct vectors: design automation, intelligent robotics, and real-time diagnostics. Each addresses a different node in the construction value chain.
1. Augmenta - Automating Design to Eliminate Rework
Augmenta, the fund's flagship buildtech investment, was founded by the ex-Autodesk team that pioneered generative design for advanced manufacturing. Its cloud-native platform automates building design production - starting with electrical systems - using spatial AI and generative models.
The productivity case is clear. Up to 30% of new building materials are wasted as a result of mis-ordering, errors, and rework linked to manual design processes, according to Augmenta's own research6Augmenta's own research. By replacing manual workflows with automated, code-compliant models generated in hours rather than weeks, Augmenta targets one of construction's most persistent cost and schedule risks: design error.
Augmenta's total funding reached $25.6 million USD as of March 2025, including a $10 million round led by Prelude Ventures. The company's roadmap extends automated design to mechanical, plumbing, and eventually full-building systems - a trajectory that, if achieved, could reshape pre-construction timelines across commercial and institutional projects. Hazelview Ventures led Augmenta's original seed round and maintains a board seat.
2. Xaba - Self-Programming Robots for Offsite Fabrication
Xaba addresses the robotics deployment bottleneck that has stalled automation in construction manufacturing. Programming and deploying industrial robots costs the industry $7 billion annually, with 80% of automation costs stemming from manually developing logic for industrial controllers, according to Xaba7according to Xaba.
Xaba's xCognition platform uses generative AI to create self-programming industrial robots - systems that receive a task description in plain language and autonomously generate the code to execute it across welding, drilling, assembling, and 3D printing operations. The company describes its goal as enabling machines to self-optimize with "up to a 10x reduction in costs."
In April 2025, Xaba secured a $6 million seed extension led by Hitachi Ventures, with participation from Hazelview Ventures, BDC Capital, and Exposition Ventures, bringing total funding to $8 million. The platform is already deployed in automotive and aerospace applications - sectors that share production process characteristics with prefabricated and modular construction, where offsite fabrication efficiency is the primary cost lever.
3. Lamarr.AI - Drone-Enabled Diagnostics for the Building Envelope
Lamarr.AI sits at the intersection of AI, drone technology, and building performance. Its platform uses computer vision and thermal imaging to detect energy inefficiencies - thermal bridging, air leakage, insulation failures - in building envelopes before they escalate into costly capital issues.
Hazelview Ventures led Lamarr.AI's $1.1 million pre-seed round, with co-participation from VentureLab and Newlab. Hazelview Properties has already piloted the technology across select assets, generating real-world performance data that feeds back into product development. The construction application extends to quality assurance during building envelope installation: catching defects at handover rather than years later, when remediation costs compound.

Adoption Barriers: Where VC Timelines and Construction Reality Diverge
Investor enthusiasm for buildtech is rising - in Q1 2025 alone, investors deployed $521 million into AI-based construction technology offerings, the highest amount since 2021, according to a Construction Dive analysis8according to a Construction Dive analysis. A Zacua Ventures survey8according to a Construction Dive analysis found that 90% of construction technology investors intended to either increase (47%) or maintain (43%) their capital deployment in 2025.
But construction's adoption track record demands scrutiny. The industry has not historically rewarded early-mover technology bets with rapid uptake. Three structural barriers remain formidable:
Legacy workflow integration. Construction firms operate across highly fragmented procurement and project management environments. As one VC observer noted, US construction firms face pressure to implement AI on top of fragmented, disconnected point solutions9US construction firms face pressure to implement AI on top of fragmented, disconnected point solutions - a compounding problem where new technology layers onto, rather than replaces, legacy inefficiency.
Workforce training gaps. New automation platforms require new skills. Data from 2025 indicates that 36% of construction CEOs are specifically upskilling staff in AI and data science, while 50% of firms cite insufficient staff support for technology adoption. Hazelview's model partially addresses this by giving portfolio companies direct access to its operational teams - but at the industry level, the skills gap remains a deployment bottleneck.
Capital intensity and rollout timelines. VC-backed seed companies operate on 18-to-36-month product cycles. Construction procurement, by contrast, runs on multi-year project cycles with risk-averse decision-making. The mismatch between investor return expectations and real-world implementation timelines is a well-recognized friction point. As one construction tech expert put it, Industry 4.0 solutions have often been "stuck in pilot purgatory, held back by rigid, code-heavy systems and legacy infrastructure."
What the Investment Model Actually Signals
Hazelview Ventures' approach is not a conventional VC play on a hot sector. More precisely, it signals that large real estate operators are internalizing the productivity problem as an investment priority - and building financial instruments that force early accountability on technology providers.
The fund invests only in technologies it can deploy internally. That constraint, far from limiting the portfolio, creates a qualification filter most generalist buildtech investors lack. When Augmenta's automated design platform is used on Hazelview development projects, or when Lamarr.AI is piloted across Hazelview's residential portfolio, the resulting performance data is not a press release - it is operational evidence.
For general contractors, architects, and project managers evaluating buildtech, that distinction matters. Products that have survived real-world deployment within a large, risk-conscious developer carry a different credibility profile than those with only lab or pilot-stage validation. The broader industry will watch Hazelview's portfolio not just for investor returns, but for implementation precedents.
Key Takeaways for Construction Professionals
- Construction productivity decline is structural, not cyclical. Fifty years of stagnation cannot be reversed without deliberate adoption of automation, AI design tools, and offsite fabrication methods.
- Integrated investors carry deployment credibility. Hazelview Ventures' model - where portfolio companies are tested within the investor's own operations - produces implementation evidence that generalist VC cannot replicate.
- Design automation offers the clearest near-term ROI. Platforms like Augmenta target pre-construction waste and rework, which carry direct cost and schedule implications without requiring changes to site operations.
- Robotics adoption will accelerate via offsite channels first. Self-programming systems like Xaba's xCognition are proving out in aerospace and automotive manufacturing before migrating to modular and prefab construction - a realistic adoption path aligned with industry procurement patterns.
- Workforce readiness remains the rate-limiting factor. Capital investment in buildtech outpaces organizational capacity to deploy and maintain it. Firms that invest in parallel upskilling will capture disproportionate productivity gains.
Frequently Asked Questions
What is buildtech? Buildtech refers to technology solutions designed specifically for the construction and building industry, encompassing automation, AI-powered design, robotics, prefabrication platforms, real-time site analytics, and building performance tools. It differs from proptech, which focuses primarily on property management and real estate transactions.
How does Hazelview Ventures differ from a standard construction tech VC? Hazelview Ventures is the VC arm of Hazelview Investments, a major Canadian real estate operator with a $13.4 billion development pipeline. It invests only in companies whose technologies can be deployed within Hazelview's own properties and construction projects, making the fund both an investor and a live testing environment - a model that reduces commercialization risk for portfolio companies.
Why has construction productivity stagnated for so long? Economists point to a combination of factors: rising land-use regulation, fragmented project-by-project procurement models that inhibit economies of scale, underinvestment in technology R&D relative to other sectors, and the industry's inherently site-specific nature, which limits standardization. According to Goldman Sachs Research, increased regulation since the 1960s alone likely reduced annual US construction productivity growth by 0.7 percentage points.
Which construction phases are most affected by current buildtech investments? Current investment activity is concentrated in design and pre-construction (AI generative design platforms), offsite fabrication (robotics and autonomous manufacturing), and building diagnostics (AI-powered envelope and energy analysis). Site operations and project scheduling tools are also attracting significant VC attention, though at later deployment stages.
What are the biggest barriers to scaling buildtech solutions? The three primary barriers are legacy workflow integration (most construction firms run fragmented, disconnected technology stacks), workforce skills gaps (insufficient training for AI and automation tools), and procurement cycles (construction's multi-year project timelines are misaligned with VC-backed product rollout expectations).
