Latest Construction Technology Funding Rounds – 4th May 2026 – Contech Funding
The week of 28 April to 4 May 2026 saw 15 startup raises across ConTech, a fresh €160m physical-industries fund from Kompas VC, and a wave of US policy moves that pull energy infrastructure back toward gas and nuclear. Robotics led the funding board with All3’s $25m seed in Switzerland, AI front-office Avoca crossed $125m total raised at unicorn status, and Japan’s BALLAS pulled in ~$15.3m for procurement. Zero acquisitions printed.
A busy week for ConTech deal flow. Fifteen startup rounds closed across AI, robotics, procurement, design, drones, monitoring, labor mobility, and green materials, spanning North Carolina to Korea and Switzerland to Saudi Arabia.

Startup funding
AI, robotics and procurement led the raises
AI was the most populated category. North Carolina’s Cloneable raised $4.6m seed for a platform that captures expert workflows from desktop and web software, then deploys AI agents to replicate them across heavy industries like utilities and telecoms. Korea’s Searchdoc raised around $2.1m for AI that analyzes documents and blueprints across industries including construction.
The headline AI raise was Avoca. The New York startup’s Series B took total funding to $125m at a $1bn valuation. Avoca builds an AI front office for home services contractors that answers calls, books jobs, and surfaces customer history in real time. Their thesis: frontier labs have already taken the data-rich application layers like coding, but trades workflows are protected by scarce data and tribal knowledge, which creates durable lock-in for whoever embeds first.
Robotics produced the largest single round of the week. All3, a Swiss startup, raised $25m seed to build a combined platform spanning autonomous on-site assembly robots, AI-powered design software, and robotic off-site fabrication for custom components. Drones were also active: Alabama-based Skyfire AI raised $11m seed for a software foundation handling autonomous drone orchestration end-to-end, used across AEC for progress tracking, earthwork, and BIM projects.
Procurement saw two notable raises. Japan’s BALLAS pulled in ¥2.4bn (~$15.3m) Series B for a custom-materials procurement platform. Saudi Arabia’s BRKZ took an undisclosed strategic investment for its contractor-facing materials marketplace.
- FORMAS AI (Singapore). $3.98m Pre-Seed for an AI design platform for architects with a live geometry canvas and 3D model studio.
- Synaps (Austria). $3.6m extended Pre-Seed for an AI architectural design and presentation platform.
- Casa (San Francisco). $20m Series A for a subscription home maintenance service using lidar scans and 1.5 hours of monthly handyman time.
- Sonibel Instruments (Canada). $1.6m Pre-Seed for acoustic sensors that identify welding defects by sound.
- Carbonyx, TimberHP, Kovon, Ubiqedge. Smaller raises across green materials, wood fiber insulation, cross-border construction labor, and AI/IoT infrastructure monitoring.

US energy mix pulls back from wind, accelerates on nuclear and grid
The week’s US policy theme: a clear shift away from offshore wind and tighter housing efficiency rules, paired with faster paths for nuclear and grid-critical hardware. Two more US offshore wind projects, totaling up to 4.4 GW, were scrapped after developers struck deals with the Interior Department to cancel leases, conditional on equivalent investment in LNG, oil, or other energy infrastructure. New Jersey’s Board of Public Utilities also canceled its 2021 PJM Interconnection agreement to build out wires and substations for offshore wind.
On nuclear, the NRC renewed the operating licence for HB Robinson Steam Electric Plant Unit 2 for another 20 years, the first under shortened federal timelines (12 months instead of 18). The NRC also proposed a rule that could bring microreactor licensing down to six to twelve months. Geothermal got its own boost: the Bureau of Land Management approved a categorical exclusion for small-scale exploration up to 10 acres on public land.
The grid story is the one to watch. The White House classified power transformers, substations, switchgear, and their upstream supply chains as essential to national defense, authorizing the Department of Energy to deploy federal capital into domestic grid manufacturing. The US imports roughly 80% of its large power transformers and 50% of its distribution transformers. For extra-high-voltage units rated 345 kV and above, foreign dependence climbs past 85%. More than half of US distribution transformers, around 40 million units, have already exceeded their expected service life.
Data centers continued to draw friction at the local level. Maine’s governor vetoed a state-wide data center moratorium that would have been the first of its kind, while Champaign County, Illinois passed a 12-month moratorium of its own, and Delaware’s State Senate passed SB 276 freeing the Delaware Electric Cooperative from having to serve large loads. HUD and USDA also rescinded energy efficiency requirements tied to the 2021 IECC for certain housing builds, citing roughly $20,000 in added cost per home. House Republicans introduced the American Energy Dominance Act to extend the renewables 45Y and 48E tax credits, citing $34.8bn in canceled clean energy investment in 2025.
Outside the US, India’s BMC mandated real-time tracking of construction and demolition waste, including vehicle tracking systems for transporters. Punjab withdrew its 2025 Unified Building Rules and reverted to the old system. In the UK, Urban Splash signaled it will fight a £48m Building Safety Fund recovery claim on human rights grounds, the first major test of the Building Safety Act’s Remediation Contribution Order powers.
Infrastructure and project signals
Wind hits a global record, US power-gear spend surges
Globally, the wind industry installed a record 165 GW of new capacity in 2025, up 40% year on year. Total installed capacity reached 1,299 GW across 138 countries. China alone added more than 120 GW. India almost doubled annual installations to a record 6.3 GW.
In the US, Bloomberg projects spending on power-generation equipment for data centers could reach $65bn by 2030, with total power-plant equipment spend across the wider grid hitting $215bn.
India fell short of its FY26 highway target, building 9,380 km against a 10,000 km goal, the slowest pace since 2017-18. In Andhra Pradesh, Amaravati capital city construction was hit by an acute diesel shortage, with around 60% of machinery non-operational from 25 April. Sweden announced a €33bn National Plan for Infrastructure running to 2037. Morocco’s state-owned natural resources company is starting fundraising for a $25bn pipeline linking gas fields in Nigeria, Senegal and Mauritania to the Mediterranean coast.
Funds and corporate moves
Kompas VC closes €160m, zero acquisitions printed
One new fund close hit the wire: Kompas VC, operating from Amsterdam, Copenhagen, Berlin, and Barcelona, announced a €160m vehicle backing physical-industries startups across manufacturing, energy, logistics, infrastructure, and the built environment. The acquisition column was empty for the week. On the news side, Anthropic’s Claude added a Thumbtack integration that lets consumers hire HVAC, plumbing, and electrical contractors without leaving the chat, tapping a network of 300,000+ US service businesses.
