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.
A Copenhagen software company, Acembee ApS, has secured €1.2 million (about DKK 9 million) in new financing to expand its AI‑powered energy monitoring and compliance platform for construction sites across Europe. The funding, announced in August 2025, was led by a Stockholm early‑stage venture capital firm and included a sector investor and a group of angel backers. The financing round was not formally named.
The company plans to use the funds to boost its AI capabilities, speed up customer onboarding, and enter additional European markets. The goal is to help more contractors move away from spreadsheets and disconnected tools toward a single platform that automates energy monitoring and compliance reporting.
Acembee offers a construction technology (ConTech) platform that pulls energy data from a range of sources—smart meters, utility bills and on‑site sensors—and turns it into usable reports and real‑time insights. The software produces lifecycle assessment (LCA) reports and formats suitable for documentation, and highlights opportunities to cut energy waste on site while keeping essential services like heated cabins and powered tool containers running.
The platform automates compliance with new national climate rules in Denmark, which set a cap on CO₂ emissions during construction at 1.5 kg CO₂e/m²/year. By continuously collecting and analysing energy data, the system reduces the time spent on paperwork and helps contractors meet tightening documentation requirements.
Contractors already using the platform have reported average energy reductions in the region of 40%, achieved without compromising operational needs on site. The system is designed as a single interface to replace multiple spreadsheets and tools, which streamlines oversight and cuts down on time‑consuming documentation tasks. Acembee has onboarded several major contractors and is preparing to roll out to more European markets.
The round was led by a Stockholm‑based early‑stage venture capital firm that focuses on high‑potential tech teams across the Nordic and Baltic regions. Additional backing came from Kiilto Ventures, the investment arm of a Finnish chemicals firm that targets climate‑positive innovations in the built environment, alongside a group of angel investors. Investor comments highlighted the appeal of teams that move quickly from idea to real customer traction and the value of sector experience when supporting climate and construction tech.
Acembee was founded in 2022 and is led by its CEO and co‑founder. The team presents the product as a way to help the whole construction industry reduce emissions and adopt AI‑driven workflows. A named customer, a head of sustainability at a contracting firm, described the system as creating clear value for contractors by saving time and improving documentation efficiency.
European and national climate rules are increasingly pressuring construction companies to report and reduce emissions. Tools that automate data collection, produce compliant reports and identify waste can ease the administrative burden and speed practical energy cuts on sites. The funding positions Acembee to add features, grow its customer base and expand outside Denmark while continuing to focus on construction‑specific needs.
The platform gathers energy data from meters, bills and sensors, analyses it with AI, creates lifecycle assessment reports and automated compliance documentation, and shows where energy can be saved on construction sites.
Acembee raised €1.2 million (approximately DKK 9 million) in August 2025. The funding round was led by a Stockholm‑based early‑stage venture capital firm and included Kiilto Ventures and several angel investors.
The money will be used to improve the platform’s AI, speed up onboarding of new customers and expand into new European markets.
The platform automates reporting required under new Danish construction climate rules, including the cap on CO₂ emissions of 1.5 kg CO₂e per square metre per year, and is suited to similar tightening rules elsewhere.
Contractors using the system have reported roughly 40% average reductions in energy use on site while keeping necessary operations like heated worker cabins running.
The lead investor is an early‑stage VC from Stockholm that focuses on tech in the Nordic and Baltic regions. Kiilto Ventures brings sector experience in the built environment and climate‑positive innovation. Angel investors add early capital and network support.
