AI-powered energy monitoring overlaying sensor-equipped construction site to automate compliance and cut energy use.
Copenhagen, Denmark, August 28, 2025
Copenhagen startup Acembee has raised €1.2 million to accelerate its AI-powered energy monitoring and compliance platform for construction sites. The funding, led by a Stockholm early-stage VC with participation from Kiilto Ventures and angels, will be used to boost AI capabilities, speed customer onboarding and expand sales across Europe. The platform collects data from smart meters, bills and on-site sensors to automate reporting, generate LCA outputs and highlight energy waste. Customers report average site energy reductions of around 40%, helping contractors meet tightening national and EU emissions rules.
Copenhagen‑based Acembee ApS has secured €1.2 million (reported as DKK 9 million) in new funding to expand its AI‑driven energy monitoring and compliance software for construction sites across Europe. The round, announced in August 2025, was led by Stockholm‑based early‑stage investor node.vc and included Kiilto Ventures plus a group of angel investors. The funding round type was not specified.
The startup will use the capital to enhance its AI capabilities, speed up customer onboarding and enter new European markets. The company’s leadership framed the investment as a step toward helping construction firms move from spreadsheets and disconnected tools to a single platform that automates energy monitoring and regulatory reporting.
Acembee builds a ConTech software platform that collects real‑time energy data from smart meters, utility bills and on‑site sensors. The system automates compliance reporting and generates lifecycle assessment (LCA) outputs in standard report formats, while highlighting opportunities to cut energy waste. The platform is designed to replace multiple spreadsheets and manual processes with a single interface that reduces administrative workload and speeds up documentation.
The product’s timing responds to tightening climate rules in Denmark and across Europe. In Denmark, new national rules place a cap on construction‑phase emissions set at 1.5 kg CO₂e/m²/year. Acembee’s software automates the collection and analysis of energy data to help contractors demonstrate compliance with such caps and other documentation requirements.
Contractors using the platform have reportedly reduced energy use by around 40% on average, even while maintaining necessary on‑site energy needs such as heated worker cabins and powered tool containers. Early adopters include several major contractors already onboarded by Acembee, which is preparing to scale operations and sales efforts into further European markets.
node.vc, the lead investor, is an early‑stage venture capital firm based in Stockholm that focuses on technology startups across the Nordic and Baltic regions. node.vc typically backs pre‑seed through Series A companies and invests in teams tackling entrenched problems in slow‑to‑change industries. Kiilto Ventures is the investment arm of a Finnish chemicals firm with sector knowledge in the built environment and a focus on climate‑positive innovations. The participating angel investors bring additional capital and industry contacts.
Acembee was founded in 2022 and is led by co‑founder and CEO Oline Ryberg Stærke. Company leadership says the new funds will allow the team to accelerate deliveries that let construction companies unlock AI benefits and reduce emissions at scale, and to position the product as a standard tool for increasingly strict energy and climate reporting.
A head of sustainability at a contractor using the system noted that the platform creates clear operational value for contractors by saving time on documentation and improving overall efficiency in meeting reporting obligations. A partner at the lead investor highlighted the team’s rapid move from idea to traction and the attractiveness of solving complex problems in a legacy sector.
The platform links directly to smart meters, ingests utility bill data and connects to on‑site sensors. It provides near real‑time monitoring, automated report generation in standard formats, and analytics that surface where energy is being wasted. Outputs include LCA reports and compliance paperwork intended to meet regulatory checks and audits.
Construction is facing growing regulatory and commercial pressure to cut embodied and operational emissions and to provide more rigorous documentation. Tools that automate data collection and reporting can reduce administrative burdens and make it easier for contractors to meet caps and targets while keeping sites operational. Acembee’s reported energy reductions and single‑interface approach speak to those needs.
Acembee raised €1.2 million (reported as DKK 9 million) in funding announced in August 2025. The funding round type was not specified.
The round was led by node.vc and included Kiilto Ventures along with several angel investors.
Funds will be used to strengthen AI features, scale customer onboarding processes and expand into new European markets.
The software automates energy monitoring and compliance reporting for construction sites, integrating smart meters, utility bills and sensors to produce LCA reports and compliance documents.
It automates data collection and reporting to support compliance with climate rules, such as the Danish cap on construction emissions set at 1.5 kg CO₂e/m²/year.
Contractors using the system have reported energy reductions of roughly 40% on average, while maintaining normal site operations.
Acembee ApS is headquartered in Copenhagen, Denmark, and was founded in 2022.
