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.
Career history
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].
In the news
- 150M annual energy spend, 1/3 of a team member? McKinsey recently flagged an industrial site where a single employee managed this spend as just one third of their role. Pretty wild! But also very common. But a tiny team is not always the dealbreaker everyone thinks it is. Some of the highest-performing energy programmes we work with run lean. If you do decide to go the lean route, there are a few non-negotiables: -Executive buy-in coupled with clear KPIs -Advanced energy tech stack to scale what energy managers can see & prioritise
- 10,000+ buildings … 50-person energy team … a few trillion data points yearly. To "manage" energy across their portfolio, this team had to log into 5 different BMS platforms and pull from dozens of utility portals and APIs. Not to mention reconciling data from tens of thousands of meters, each on a different format, vendor, and frequency… The size of the energy team is NOT the problem here. Even with 50+ people dedicated to energy, there's no way they can go through all those streams every day, let alone make strategic decisions on
- Webinar: how do you build an energy data setup that scales? Putting meters in place is the easy part. Installing them the right way, in the right spot, is not. The hard part comes after: turning scattered data streams into a clean, centralised layer you can trust and act on. A lot of organisations start with a bad setup from a local advisor, and a year or two later it doesn't meet the new norms, or it just won't scale. So the whole thing has to be rebuilt. All that capex, spent twice. That's what we will be discussing in our webinar:
- Our team's theme this quarter is KISS. Keep it simple, keep it speedy. It's how a startup beats a company ten times its size. Not by outspending them, but by building beautifully simple solutions, beautifully fast. So, in every meeting, every project, every task, we ask the same annoying little question: what's the simplest version that works? Sounds easy. It's not. Complexity is the default. Simplicity is the discipline we have to keep reminding ourselves to hold. PS: Enersee is growing fast and we need more hands. Some very
- Chess computers beat humans pretty fast at chess. But a centaurs (a human chess master fused with an outdated chess computer) still beat the most advanced chess computers for a long time. Intuition and interpretation + brute calculation turns out to be a heck of a combo. Stockfish and Alphazero (amongst others) do beat centaurs these days. But that is in a very “simple” clean world with fixed rules, called Chess. Now picture the real world, where the rulebook is missing. Our vision: human + machine combos will be beating pure AI

- In food-retail. Energy cost = 50% of EBITDA 81% of retail execs say they expect margin expansion in 2026. But if grocery margins are currently stuck at 2-4%, where will that expansion actually come from? How will they use AI to get there? Per a 2026 Deloitte report, AI investment is mainly flowing into: -Fraud detection -Pricing optimization -Customer service chatbots -Demand forecasting -Supply chain visibility Notice what’s missing? Energy. This list might make sense if you're selling clothes. Grocery is another story — with
- One thing derails more ISO 50001 projects than bad data or missing meters: No executive ownership of energy strategy. Ask "who's in charge of energy here?" and you get multiple names. Which means, effectively, no one. The compliance lead wants to move. The energy manager builds Power BIs in a corner. This means SEUs (Significant Energy Users) get logged and baselines created. But without a mandate and clear KPIs from above, nothing actually gets fixed. And Energy-cost remains that big bloated line on the P&L… At Enersee we see this
