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.
Acembee ApS, a Copenhagen‑based ConTech company, secured €1.2 million (approximately DKK 9 million) in August 2025, with node.vc serving as the lead investor. Additional participation came from Kiilto Ventures and a group of angel investors. The funding is earmarked to enhance AI capabilities, accelerate customer onboarding, and expand into new European markets.
Acembee is a ConTech / AI‑powered energy monitoring & compliance platform designed to help contractors move away from spreadsheets and disconnected systems. The platform automates energy monitoring and compliance reporting for construction sites in line with climate regulations. It ingests data from smart meters, utility bills, and on‑site sensors, then outputs actionable insights and reports.
The system generates lifecycle assessment (LCA) reports in formats including A4 and A5, and identifies opportunities to reduce energy waste. It also automates compliance with Danish climate rules, collecting and analyzing energy data to ensure construction projects stay within regulatory limits.
Danish regulations set a cap on CO₂ emissions during construction at 1.5 kg CO₂e/m²/year. Acembee’s platform is designed to help meet this cap by providing real‑time data collection, automated reporting, and insights that support emissions reductions without compromising project timelines.
The platform supports real‑time data collection and automated reporting, giving project teams a single interface to monitor energy use. This replaces multiple individual tools and spreadsheets, reducing documentation overhead and improving oversight.
Early adopters using Acembee report average energy reductions of around 40% while maintaining essential operations such as heated worker cabins or tool containers. The company has onboarded several major contractors and is positioned to accelerate expansion across Europe.
The CEO and co‑founder, Oline Ryberg Stærke, frames the investment as more than building a product—it’s about helping an entire industry move forward and unlock AI benefits to reduce emissions. Investors bring sector‑specific experience: node.vc, an early‑stage fund from Stockholm that backs Nordic and Baltic technology startups, emphasized a preference for teams solving complex problems in slow‑changing industries; Kiilto Ventures, the investment arm of the Finnish chemicals company Kiilto, focuses on climate‑positive innovations in the built environment.
With the new funding, Acembee plans to scale its AI capabilities, accelerate onboarding, and pursue expansion into new European markets, leveraging regulatory momentum and a growing emphasis on greener construction practices.
The funding round is recorded at €1.2 million (reported as DKK 9 million) and is supported by a combination of venture capital and strategic investors. The initiative underscores a broader trend of increasing investment in tools that streamline compliance and energy management across the construction sector.
Acembee provides an AI‑powered energy monitoring and compliance platform for construction sites, consolidating data from meters, bills, and sensors to automate reporting and lifecycle assessment outputs.
The round was led by node.vc, with Kiilto Ventures and a group of angel investors participating to support European expansion and product enhancement.
The platform helps ensure compliance with climate regulations, including a Danish cap on CO₂ emissions during construction of 1.5 kg CO₂e per square meter per year, by automating data collection and analysis.
Reported reductions from customers using the platform are around 40% in energy usage, achieved while maintaining essential on‑site operations.
Expansion plans focus on broader European markets, supported by the new investment and the platform’s ability to scale across sites and regulatory regimes.
