TEGnology

With a core technology of thermal energy harvesting, TEGnology works on smart power supply solutions for future IoT devices, which don't rely on batteries or cables. It opens opporutnities for generating more data, making more precise moniroting, or installing sensor in the places difficult to reach. Digital transition and industrial automantion sill based on installing a large number of wireless sensor nodes, most of which are currently powered by batteries. Despite the relatively low cost of batteries, the enevitable man-powered involved in maintaining the keeping track of batteries might be problematic, not to mention batteries pollutes. Thermal energy harvesting converts temperature gradience directly into electricity. No moving parts or chemical reactions are involved. The lifetime of thermal generator is therefore typically decades. During the entire lifetime, more energy can be provided than any type of batteries. All materials used in TEGnology’s thermal energy harvesters are abundant and environmentally-friendly. The manufacture method is compatible with existing industrial standard. It makes up-scaling of production relatively straightforward.

Flowering.dk

Centrally located in Copenhagen, Flowering is developing bouquets with a reduced CO2 output to help environmentally conscious customers reduce waste and promote sustainability with beautifully crafted, eco-friendly floral arrangements. Flowering addresses the significant issue of flower waste in the floral industry. This problem affects both the environment and flower producers, contributing to unnecessary carbon footprints. The widespread waste impacts growers, retailers, and consumers who seek sustainable alternatives. Our team at Flowering sources surplus flowers that would otherwise be discarded and repurposes them into beautiful, high-quality bouquets in combination with local and certified flowers. By implementing efficient logistics and innovative design processes, we ensure these flowers reach customers fresh and vibrant, reducing waste and promoting sustainability without any intermediaries. The inspiration for Flowering came from witnessing the vast amounts of perfectly good flowers being discarded daily. Motivated by a passion for sustainability and a desire to make a positive environmental impact, we left our jobs and studies to focus on creating a business that not only delivers beauty but also champions environmental responsibility.

Treesy ApS

Treesy ApS er en dansk climate tech-startup, der gør det nemt, billigt og gennemskueligt for privatpersoner og virksomheder at tage konkret klimahandling gennem træplantning i Tanzania. Mange mennesker og virksomheder ønsker at gøre noget for klimaet, men oplever i dag, at løsningerne er uoverskuelige, dyre, abstrakte eller svære at stole på. Samtidig vokser både klima- og biodiversitetskrisen, og behovet for skalerbare, troværdige og handlingsorienterede løsninger er større end nogensinde. Treesy er skabt for at fjerne barriererne for klimahandling. Vi tilbyder en enkel abonnementsbaseret model, hvor kunder planter træer som en konkret måde at reducere og balancere deres klimaaftryk. Vores tilgang er baseret på konservative beregninger, radikal transparens og lokal forankring. Alle træer plantes i samarbejde med lokale partnere i Tanzania og bliver: • individuelt geo-tagget • monitoreret mindst fire gange årligt • passet og genplantet i op til tre år efter plantning Vi planter et diversificeret mix af træer med fokus på både klima, biodiversitet og lokal økonomi. Det betyder, at vores indsats ikke kun handler om CO₂, men også om at styrke økosystemer, skabe lokal indkomst og opbygge mere robuste lokalsamfund gennem agroforestry og frugttræer. Treesy adskiller sig ved at kombinere: • lav pris pr. træ • høj grad af transparens • direkte lokal tilstedeværelse • individuel geo-tagging af træer • en bevidst fravalg af dyre certificeringssystemer til fordel for direkte dokumentation Vores ambition er at gøre klimahandling tilgængelig for alle — og samtidig sikre, at indsatsen skaber reel, målbar og langsigtet impact. Treesy er stiftet af iværksættere med mange års erfaring fra udviklingsarbejde i Afrika og et stærkt lokalt netværk. Vi tror på, at ægte forandring skabes, når klima, biodiversitet og social udvikling tænkes sammen i én samlet løsning. Vores mission er enkel: At gøre det så nemt og gennemskueligt som muligt at give mere tilbage til planeten, end man tager.

Tepui Agentic Labs

Tepui Agentic Labs is Europe’s first AI-native agentic data platform , built in Denmark from the ground up on EU-sovereign infrastructure for mid-market businesses trapped on legacy systems. Most mid-market companies across Europe are sitting on years of valuable business data locked inside outdated databases, spreadsheets, and disconnected systems. They have no data team to fix it, and enterprise solutions are priced for companies ten times their size. The result: critical business decisions made on gut feel, manual reports that take days to assemble, and institutional knowledge trapped in files nobody dares to touch. Tepui solves this with three product lines. Datarcon modernises legacy data, extracting, cleaning, and transforming it into a modern analytics layer the business actually owns. Our Sovereign SaaS platform lets companies run AI-powered tools on EU infrastructure with no data leaving European soil ,fully compliant, fully controlled. And Tonin, our autonomous 24/7 AI agent, monitors the business continuously, triggers alerts, generates reports, and answers operational questions in plain language. Tonin is not a chatbot , it is an always-on intelligence layer that works while the team sleeps. A standout feature of our AI agents is the Consciousness Core , an integrated ethics layer ensuring responsible AI behaviour and compliance with the EU AI Act from inception. Every agent decision is traceable, auditable, and explainable by design. The platform is built on an enterprise-grade 7-layer security architecture, fully EU-sovereign with no data leaving European soil. We serve multiple industry verticals across Denmark hospitality (restaurant groups, hotels), construction (mid-market contractors), social housing (almene boligorganisationer), investment funds (PE, VC, family offices), food suppliers, automotive (parts distributors, dealer groups), and law firms with additional verticals in development. Every vertical has the same problem: years of data locked in systems that never talk to each other. Same core product, different industry configuration. We are pre-seed, incubated at ITU NextGen Incubator 2026, and actively pursuing first pilot clients in Denmark.-sovereign deployment on European infrastructure as standard. Made in Denmark. Built for Europe.
