Overview

Joachim Vleminckx is co-founder and CEO of Enersee, an energy management software company headquartered in Antwerp with an office in Brussels. He started the company with Maarten Van de Vijver, and the two founders combine expertise in energy efficiency, automation, data science, and environmental technology. Enersee offers an AI-powered platform that works as a 24/7 virtual energy manager for buildings. It identifies energy inefficiencies, prioritises optimisation opportunities, and tracks the return on efficiency projects across property portfolios. The platform manages more than 1,000 sites, and customers include Delhaize, bpost, Korian Group, VDAB, Veolia, UCLL, Stad Hasselt, Van Roey Services, Armonea, Belfius, and URW. Delhaize Belgium selected the software for its network of 700 stores, and at one store the monthly energy bill fell from €20,000 to €12,000. In September 2025 Enersee announced a €4 million late-seed round led by 6 Degrees Capital, with participation from Peak and angel investors Alex Brabers, Bernard Hazard, Laurent Michiels, and Vincent Nagels. The capital funds growth of the customer success and product teams, international scaling, and platform additions such as tariff-normalised cost views, solar and battery integration modules, and automated contractor dispatching.

Insights & ideas

Vleminckx sees energy management as a critical but systematically neglected lever for enterprise profitability, particularly in capital-intensive sectors like grocery retail. His core observation is stark: while grocery margins hover at 2-4% and energy represents roughly 50% of EBITDA [1], AI investment in retail is flowing toward fraud detection, pricing, and chatbots rather than energy optimization [1]. A 20% reduction in energy costs yields a 10% EBITDA increase [1], a mathematical reality that he argues should reshape corporate technology priorities.

The second recurring theme is organizational dysfunction. Vleminckx identifies a widespread failure mode: energy strategy lacks executive ownership [2]. When asked who owns energy, companies produce multiple names, "which means, effectively, no one" [2]. Compliance leads, energy managers, and facility teams operate in silos, producing data and baselines without the mandate or clear KPIs needed to drive actual fixes [2]. This structural problem persists even when companies invest in ISO 50001 certification, which generates monitoring capability but not management discipline.

He has developed a diagnostic framework showing how organizations progress from "monitoring" to "managing" energy [3]. The stages move from invoice-based decisions through data centralization, to actual insights, then to financial-impact-ranked anomaly detection with automated workflows, and finally to continuous compliance automation [3]. He observes that most portfolios remain in stage one, with almost none reaching stages four or five [3]. This suggests that the barrier is not technical but organizational, a lack of systemic commitment rather than unavailable tools.

Vleminckx also expresses skepticism toward energy technology vendors claiming AI capabilities [7]. He distinguishes between genuinely "AI-native" companies that built data architecture first and legacy monitoring platforms that "slapped on" AI to existing systems [7]. The latter still produce false alerts and lack the data compatibility needed for real analytics at scale [7].

On talent and climate strategy broadly, he identifies a perverse imbalance: billions are spent annually on climate reporting and disclosure compliance, yet only one in three companies meet their own targets [6]. LinkedIn shows energy management as the fastest-growing green skill, but this is self-reported; actual practitioners who can "drive reductions" remain scarce [6]. The skill gap is real because the job now demands demand response, grid interaction, procurement, and regulatory compliance, not just monitoring [6].

Finally, he views European AI sovereignty as nonnegotiable [4]. When the US restricted Anthropic's Claude access, he framed this as an existential concern: "EU sovereignty at stake" [4]. His position is pragmatic rather than protectionist, continue working with American companies, but European enterprises must "create optionality fast" by supporting European AI companies at scale [4].
