  • Companion.energy

    Participated · Seed · Jun 2026

    Companion.energy operates a platform that unifies energy contracts, live operational data, and distributed assets to continuously forecast demand, track market exposure, and automatically execute energy decisions. The company positions its software as a system of execution rather than a monitoring dashboard, directing assets to times of lower prices or profitable grid sales. Founded in 2022, the 19-person startup reports more than €1M in annual recurring revenue after tenfold growth since May 2024 and serves major customers including TotalEnergies, KPN, the Port of Antwerp–Bruges, Interparking, and Proximus Group. It now manages over 2 TWh of annual energy use and supports more than 200 MW of distributed solar, wind, batteries, and EV charging assets. Companion.energy plans to use its recent funding to enhance multi-asset, multi-market optimisation and to expand into Germany and Spain.

  • CONXAI

    Participated · Equity · Apr 2026

    Founded in 2020 and led by CEO Sharique Husain, CONXAI builds a vertical AI platform tailored to the architecture, engineering, and construction (AEC) industry. Its platform ingests and processes multi-modal data sources including images, video, sensor inputs, documents, and CAD files to support construction workflows. CONXAI’s proprietary Neuro-Agentic Reasoning Architecture combines domain expertise with multi-modal AI to provide explainable and auditable automation for complex, context-dependent tasks. The company plans to use the newly raised €5.0M to expand product capabilities, scale deployments, and accelerate global adoption. The article does not disclose revenue, user metrics, prior funding amounts, or valuation.

  • VerbaFlo

    Led · Seed · Mar 2026

    VerbaFlo provides a purpose-built AI communications layer for residential real estate, deploying specialised AI agents across leasing, marketing, operations, and maintenance and integrating with existing property systems. The platform centralises conversations across email, web chat, messaging apps, and phone to enable real-time, multilingual engagement at scale. VerbaFlo aims to improve response times, increase conversion rates, and reduce operational workload for property operators. The company currently supports more than 200,000 units globally and has grown across the UK and Europe with recent expansion into the United States. Founded in 2024, VerbaFlo plans further international rollouts and continued product development funded by its recent seed raise. Its commercial positioning emphasises vertical-specific AI automation rather than general chatbot solutions.

  • AIRMO

    Participated · Seed · Mar 2026

    AIRMO is a Berlin- and Luxembourg-based space-tech startup developing an active greenhouse-gas monitoring instrument that pairs a SWIR imager with micro-LIDAR, miniaturised for use on small satellites. The system delivers roughly double the accuracy of existing solutions and can spot methane leaks as small as a car from orbit. Today AIRMO’s technology is already flown on drones and aircraft for commercial monitoring missions across Europe, Central Asia and the MENA region, serving energy majors such as Uniper, Total and ESCE. Backed by the European Space Agency, the company plans its first satellite launch in 2027 to enable continuous, global methane surveillance of millions of energy assets. Proceeds from its recent seed round will also fund expansion of its airborne operations and the establishment of a local MENA presence. While revenue figures are not disclosed, the fresh capital strengthens AIRMO’s balance sheet as it transitions from pilot projects to scaled commercial deployments.

  • Elyos AI

    Participated · Series A · Jan 2026

    Elyos AI provides an AI platform that sits between customers and trades businesses—such as contractors and service operators—to instantly manage inbound calls, capture job details, and schedule appointments end-to-end. The agents also handle follow-up communications, missed calls, and billing or invoicing workflows, aiming to reduce lost revenue caused by unreturned inquiries and administrative overload. A key differentiator is the product’s ability to integrate directly with existing scheduling, CRM, and back-office tools, allowing small teams to adopt AI without disrupting their workflows. The company positions its solution as a complete “digital front office” that can replace or augment receptionists, dispatchers, and office managers. Elyos AI plans to enhance multi-channel engagement across voice, email, and messaging while improving agent performance. With fresh capital, it intends to expand internationally in 2026 and is actively hiring across product development and go-to-market roles. The recent funding underscores its ambition to scale both technology and market reach.
