TechWolf

In most large Belgian organisations, the org chart looks tidy while the reality underneath is messy. Job titles at a Brussels bank or Antwerp manufacturer rarely match what people actually do, and traditional HR systems rely on self-reported skills that go out of date the moment projects change. That makes AI-era reskilling and internal mobility a guessing game.

From static CVs to live skills graphs

TechWolf, spun out of Ghent University, tackles this by inferring real skills from day-to-day work artefacts: documents, tickets, code, learning records and more. Using a mix of NLP and computer vision, it builds a constantly updated “skills graph” of the workforce rather than a static CV database. This “Skill Intelligence” approach is one reason TechWolf sits prominently in rankings of Belgian AI startups to watch.

Serious capital, serious customers

The company has raised around €54 million, with investors like Felix Capital and Stride.VC backing its category-defining ambitions, according to funding trackers such as GrowthList’s overview of Belgian startups. Enterprise customers include global employers like HSBC and GE Appliances, proving the platform can operate at tens-of-thousands-of-employees scale, not just in pilot mode.

Why Belgian AI talent should care

For AI and ML practitioners in Belgium, TechWolf is a concrete example of how to turn unstructured enterprise data into high-value decisions that matter to both workers and regulators.

• It sits directly in the flow of work at large employers (think Proximus, major banks, or EU institutions), influencing who gets reskilled for AI-heavy roles.
• Its models must respect European privacy, labour and union expectations, making it a live testbed for “responsible AI” at scale.
• It’s aligned with EU priorities around lifelong learning and skills passports, giving Belgian engineers a front-row seat in how policy and AI products interact.

Vertical Compute

Walk a few minutes from the EU quarter towards the inner ring and “sovereign AI” stops being a slogan and becomes a hardware problem. European institutions, Belgian telcos and local cloud providers all want advanced AI, but most of the GPUs and accelerators they depend on come from the US or Asia, with price, export-control and latency headaches attached.

Building chips for Europe’s agentic AI wave

Vertical Compute, split between Brussels and Liège, is tackling this bottleneck by designing specialised AI chips and systems optimised for high-speed deployment of complex, “agentic” AI workloads. The company leans on semiconductor know-how embedded in Wallonia and Flanders and the broader deep-tech dynamics tracked by platforms like Vestbee’s coverage of Belgian innovation.

Anchored in imec’s orbit, wired into policy

What makes Vertical Compute distinctive is the way it connects imec-linked R&D in Liège and Leuven with decision-makers in Brussels. That geography gives it direct access to fabrication expertise, EU Chips Act conversations and early customers among local cloud, SaaS and telecom players. Support from regional funds such as Noshaq, Wallonie Entreprendre, InvestBW and the Flanders Future Techfund ties it into both Walloon and Flemish industrial strategies.

One of Belgium’s biggest early hardware bets

The company reportedly closed a €57 million Seed round in March 2026, led by Quantonation alongside public and private regional investors, making it one of the largest early-stage hardware financings recorded in Belgian VC deal trackers like InforCapital’s overview of national rounds. For Belgian AI engineers used to working purely in software, Vertical Compute is a signal that serious capital is finally flowing into local silicon.

If it can turn policy tailwinds into anchor deployments with European cloud providers and telcos headquartered around the Benelux, Vertical Compute is a plausible acquisition target for a major chipmaker or hyperscaler wanting both hardware IP and a bridge into EU institutions only a tram ride away.

Aikido Security

For many Belgian engineering teams, “security” still means juggling half a dozen tools, each firing off alerts nobody has time to triage. With NIS2 raising the bar for everything from SaaS scale-ups in Ghent to managed service providers in Brussels, that noise is becoming a regulatory risk rather than just an annoyance.

An AI-native shield for Belgian dev teams

Aikido Security, based in Ghent, pulls static code analysis, software composition analysis, DAST and cloud scanning into a single platform, then uses AI to rank what actually matters. Instead of flooding Jira or GitHub with low-priority warnings, Aikido focuses developers on a small, ordered set of vulnerabilities surfaced directly in their existing workflows. That developer-first positioning is one reason it features prominently in EU-Startups’ list of cybersecurity innovators.

• A single pane of glass for SAST, SCA, DAST and cloud checks, tuned for smaller teams without an enterprise SOC.
• AI correlation across repositories and services, reducing duplicate alerts and highlighting issues with real exploit paths.
• A founding team of serial entrepreneurs, including Willem Delbare, bringing go-to-market muscle that many security tools lack.

From Ghent canals to unicorn status

Aikido has quickly become one of Belgium’s best-funded AI-native security companies. After an earlier Series A from Singular and Notion Capital, it vaulted into unicorn territory with a $60 million (around €55 million) round reported by the Belga news agency. That capital is fuelling expansion across Benelux and DACH, just as NIS2 obligations hit SMEs, hosting providers and digital infrastructure operators.

For AI and ML professionals in Belgium, Aikido is a compelling case study in applied machine learning: models that have to be explainable enough for auditors yet fast and pragmatic for developers racing to ship features. It’s also a signal that you don’t need to move to London or the US to work on world-scale security problems - those challenges are now being tackled a train ride away along the Ghent-Brussels line.

LegalFly

On any given day, Belgian legal teams are stitching together contracts in Dutch, French and English, cross-referencing EU directives with Belgian company law and sector-specific rules. Generic US-built chatbots struggle with this mix of languages and jurisdictions, and they raise hard questions about confidentiality and where sensitive documents are processed.

Legal-grade GenAI for multilingual workflows

LegalFly, based in Ghent, positions itself as an AI-native workspace for in-house legal, compliance and procurement teams. It uses generative AI and NLP to support automated contract review, drafting assistance and litigation preparation, but with strict guardrails: client data is treated as legal-grade and is not reused to train shared models. The platform is optimised for Dutch-French-English workflows, which makes it a practical fit for Belgian corporates and institutions that operate across language borders every day.

• Document analysis that flags risky clauses and suggests alternatives grounded in EU and Belgian practice.
• Drafting assistance tuned to house style and jurisdiction, not just generic “legalese”.
• Deployment patterns that respect EU expectations around data residency and professional secrecy.

Funded to scale beyond the Ghent canals

LegalFly closed a significant Series A round in 2025, led by Redalpine with participation from local Ghent-based investors, as highlighted in investor mappings such as Shizune’s overview of Belgian AI investors. It also appears among national “startups to watch” shortlists that track how Belgian AI is moving from pilots to core business systems.

Where AI law, policy and practice meet

With the EU AI Act treating many legal applications as high-risk, tools like LegalFly must combine strong model performance with auditable behaviour. That combination of compliance and innovation is one reason it features in selections such as Why.Brussels’ “rising stars” of Belgian AI. For AI engineers and data scientists, LegalFly is a front-row seat to applying LLMs, retrieval-augmented generation and document intelligence in one of Europe’s most sensitive, multilingual domains.

Timefold

When you zoom out from the Ghent canals to the Port of Antwerp-Bruges, Belgium looks like one big optimisation puzzle. Freight trains, barges, technicians, home-care nurses and field engineers all have to be in the right place at the right time, under strict EU labour rules and traffic constraints. Traditional planning tools and spreadsheets crack under that kind of real-time complexity.

An optimisation engine with open-source DNA

Timefold takes that constraint chaos and turns it into an optimisation problem you can actually solve. Building on the open-source heritage of OptaPlanner - created by co-founder Geoffrey De Smet - it offers an AI-powered planning engine that blends classic operations research with machine learning. The result: schedules and routes that respect hard constraints (union rules, driving hours, SLAs) while continuously learning from historical data.

• Routing for logistics and last-mile delivery.
• Shift planning for field services, technicians and healthcare staff.
• Maintenance and production scheduling in manufacturing environments.

Funded to become Benelux’s “planning brain”

Timefold raised around €6.7 million in late 2025/early 2026, led by Lakestar and SmartFin, a meaningful round for a deep-tech B2B platform at this stage and part of a broader wave of Belgian AI funding captured in Consultancy.eu’s analysis of open innovation. The platform is gaining traction with EU logistics and field-service providers who need cross-border scheduling that plays nicely with EU labour law.

Where Belgian AI talent fits in

For developers and data scientists, Timefold is a chance to work on applied optimisation at national scale: integrating with ERPs like Odoo or SAP, building vertical solutions for utilities or hospital staffing, and turning mathematically elegant algorithms into on-the-ground gains for Belgian and Benelux operators. In a country where about 90% of organisations see startup collaboration as key to their AI strategy, tools like Timefold are increasingly becoming the hidden engines behind everyday services.

Swave Photonics

In Leuven, a short train ride from Brussels, holography is moving from sci-fi to lab reality. Tucked inside the wider imec ecosystem, Swave Photonics is working on displays that don’t just show flat 3D illusions, but project light fields your eyes and brain can treat as genuinely three-dimensional.

Holographic eXtended Reality, born from imec

Swave is an imec spin-off developing what it calls Holographic eXtended Reality (HXR) - combining photonics, semiconductor engineering and AI-driven rendering to produce realistic holographic images on compact hardware. The company sits alongside other imec-born ventures listed in the institute’s own overview of spin-offs from its Leuven labs, giving it access to world-class cleanrooms and fabrication expertise.

For use cases like surgical planning, complex equipment maintenance or high-end retail experiences, that matters: current AR/VR headsets often cause eye strain and lack depth cues. Swave’s technology targets true light-field reconstruction, where AI models can optimise hologram generation based on scene content, user position and device constraints.

Deep-tech IP with global pull

Backed by investors including Qbic Fund, imec.istart and Acequia Capital, Swave focuses heavily on defensible IP around holographic displays and photonic chips. Its position in Leuven’s semiconductor cluster lets it prototype devices that are not just visually impressive, but manufacturable at scale for OEM partners in Europe, the US and Asia.

Why Leuven’s holography matters for your AI career

For Belgian AI and ML practitioners, Swave is a clear signal that cutting-edge work doesn’t only live in cloud APIs. It shows up in cross-disciplinary teams where neural networks meet diffraction patterns, optics and hardware constraints. That mix of physics and AI is one reason international mappings like Novable’s list of influential Belgian AI startups spotlight photonics players alongside more traditional software ventures.

Beebop

On the ring road into Antwerp, you can see Belgium’s energy transition in real time: rooftop solar, harbour wind, battery containers tucked behind warehouses. For grid operators and large industrials, that decentralised mix is a control problem more than a construction one. Traditional SCADA tools were never designed for thousands of small, volatile assets making decisions at the edge.

Turning volatility into a controllable system

Beebop, based in Antwerp, builds vertical AI for this exact challenge. Instead of focusing only on demand or only on generation, its platform ingests data from solar, wind, batteries and flexible loads, then uses machine learning to orchestrate them in real time. The aim is to help DSOs and TSOs stabilise grids as renewables and storage grow, aligning closely with EU Green Deal priorities and Belgium’s own climate plans.

Beebop moves beyond pure forecasting. Models propose control actions on assets minute by minute, within strict safety and regulatory constraints, turning the grid into a dynamic optimisation problem rather than a static infrastructure asset.

From pilots to long-term grid partnerships

The company has raised about €5.5 million, enough to support serious pilots with major Belgian grid operators and energy providers. These collaborations are part of a broader wave of AI-led innovation mapped in the Federal Planning Bureau’s overview of Belgian AI start-ups across sectors. Funding databases such as Tracxn’s listing of Belgian rounds highlight how energy-focused AI ventures are beginning to attract specialised capital.

Why Antwerp’s grids matter for your AI career

For AI and ML practitioners, Beebop offers a rare mix of hard constraints and high impact: reinforcement-style decision systems that must satisfy regulators, keep lights on in Antwerp and avoid penalties in cross-border electricity markets. It is also a natural collaboration partner for other Belgian climate-tech and industrial AI players, making the port city one of the most interesting places to work on real-world, system-critical machine learning in Europe.

Wobby

In many Belgian organisations, the real knowledge doesn’t live in dashboards; it lives in PDFs, slide decks and 80-page research reports sitting on shared drives. Generic chatbots might give you a confident answer, but they rarely tell you where it came from - a non-starter for legal, compliance or public-sector teams whose reputation depends on traceable evidence.

From “chatty” AI to verifiable research assistant

Wobby, headquartered in Antwerp, is an AI-powered information and knowledge management platform built for exactly this gap. Instead of aiming for creative copy, it focuses on citation-first, source-transparent outputs: every generated insight, chart or paragraph is backed by explicit references to underlying documents. Coverage in specialist research media describes Wobby as a data gathering and visualisation firm helping insight teams turn unstructured material into usable evidence, as reported by MrWeb’s profile of Wobby’s funding round.

• Uploads and indexes reports, transcripts and datasets into an enterprise knowledge base.
• Uses AI to draft summaries, tables and visualisations with linked citations.
• Makes it possible to audit what the model used and how it reached an answer.

Early traction in the research and insights world

Wobby has secured around €1.2 million in Seed funding, enough to build out the product and win early adopters among research agencies and insight teams whose clients pay for rigour, not just speed. Its positioning fits neatly into Belgium’s tradition of policy analysis and market research, from Brussels-based consultancies to Antwerp logistics and retail specialists.

Why this matters for Belgian AI careers

For AI and ML professionals, Wobby is a reminder that the next wave of generative AI in Belgium will be judged less on novelty and more on trustworthiness. Building retrieval-augmented generation stacks that survive legal scrutiny, public tender requirements and EU audit standards is becoming a core skill, reflected in ecosystems tracked on platforms like the F6S directory of Belgian startups. Antwerp’s focus on logistics, research and media makes it a natural hub for this “verifiable AI” niche.

Nexus

In Brussels, the hype around AI “agents” has finally reached the glass meeting rooms of Rue de la Loi and the Avenue Louise towers. Legal teams, policy units and operations managers all want assistants that don’t just answer questions, but trigger workflows across CRMs, ERPs and ticketing tools. The sticking point is not the models; it is deployment, integration and governance.

The orchestration layer for enterprise agents

Nexus, headquartered in Brussels, focuses on this missing middle. Rather than building yet another model, it offers a platform where non-technical teams can design, deploy and monitor AI agents that act across existing systems. Think of it as an orchestration and safety layer between LLMs and tools like Salesforce, Odoo or ServiceNow, with audit trails that compliance officers can live with.

This positioning aligns Nexus with a growing set of implementation-focused players mapped in directories such as Clutch’s rankings of AI consultants in Belgium, where integration and governance capabilities increasingly matter as much as raw model performance.

Backed by global and local capital

Nexus closed a €3.7 million Seed round in April 2026, with General Catalyst and Y Combinator among the investors. That combination of US acceleration and Brussels location is rare for a Belgian startup at this stage and positions Nexus well for collaboration with both multinational HQs and EU institutions based in the city.

Why Brussels is a natural home for Nexus

Operating from the capital means building directly against the constraints of the EU AI Act, data protection rules and complex, multilingual workflows. It is the kind of environment celebrated by initiatives like the Belgium Startup Awards, which highlight AI ventures turning regulation into a competitive advantage. For Belgian AI and ML engineers, Nexus offers hands-on experience with agent-based architectures, tool integration and real-world governance problems that every serious European deployment will soon face.

Sirona Technologies

Down in Brussels’ Canal Zone, between former warehouses now housing makerspaces and climate NGOs, Sirona Technologies is tackling one of the hardest problems in climate tech: pulling CO₂ back out of the air at scale, and doing it cheaply enough that companies and governments will actually pay.

Direct Air Capture with an AI control layer

Sirona builds modular Direct Air Capture (DAC) units and uses AI to optimise how they run in real time. Models tune process parameters such as airflow, sorbent regeneration and energy use, constantly trading off capture efficiency against electricity prices and hardware wear. The goal is simple but brutal: drive down the cost per tonne of CO₂ removed while keeping systems robust enough for industrial customers.

• Adaptive control that responds to changing temperature, humidity and grid conditions.
• Predictive maintenance on fans, filters and sorbents to minimise downtime.
• Scenario modelling to design future DAC sites in Belgium and neighbouring markets.

From Tesla-style hardware culture to Brussels climate policy

Founded by former Tesla and SpaceX engineers, Sirona brings a Silicon Valley hardware-iteration mindset into the heart of EU policymaking. Its Seed round, led by LocalGlobe and XAnge with support from Belgian public funds, places it alongside other high-potential ventures highlighted in cross-border selections such as “10 Belgian startups to watch in 2026 and beyond”.

Why carbon removal is becoming an AI career path

As EU climate policy shifts from targets to enforcement, verifiable carbon removal is emerging as a distinct market. Belgian startup roundups, including overviews like Discovering Belgium’s list of startups to watch, increasingly highlight climate-tech as a growth pillar. For AI and ML practitioners, Sirona offers work at the intersection of reinforcement-style control, physical modelling and regulation-heavy markets, with every model update ultimately measured in tonnes of CO₂ actually removed from the atmosphere.

Reading the chalkboard and going off-menu

Step back from the individual startup stories and you’re back at that bar near Sainte-Catherine: a bright “Top 10” rectangle on the chalkboard, and a cellar full of bottles you’ll never taste in one night. This list is the same kind of shortcut. It highlights where capital, research and customers are already flowing, but it inevitably leaves out quieter lambics: bootstrapped teams in Liège, niche B2B tools in Charleroi, early-stage spin-offs deep inside KU Leuven or ULB labs.

Seeing the lens behind every ranking

What makes the names here stand out is a particular lens: recent funding, ties to research engines like imec, KU Leuven, Ghent University or ULB, and evidence of EU-scale traction in areas like security, logistics, legaltech and energy. But other lenses - social impact, open-source contributions, diversity, regional balance - would surface different players. As one long-form analysis for Baillie Gifford’s exploration of AI and work puts it, the real shift is cognitive: learning to question how systems, including rankings, are constructed.

From curiosity to concrete next steps

If you’re building an AI career in Belgium, treat this chalkboard as a tasting flight, then go off-menu:

1. Follow who’s hiring and raising in Brussels, Ghent, Leuven and Antwerp, not just the biggest rounds.
2. Show up at meetups in places like BeCentral, Digityser or imec, and watch which collaborations quietly form between startups, corporates and EU bodies.
3. Invest in skills that travel well across employers - from MLOps and data engineering to prompt design and optimisation.

A structured way to skill up

Getting there doesn’t require a €9,000 campus bootcamp. Programmes like Nucamp’s 25-week Solo AI Tech Entrepreneur track (around €3,700), the 15-week AI Essentials for Work (about €3,300) and the 16-week Back End, SQL and DevOps with Python (roughly €1,950) are designed for people in Brussels, Antwerp, Ghent or Leuven who are working or switching careers. With an employment rate near 78%, a graduation rate around 75% and strong learner reviews, they offer a structured way to join the teams shaping Belgium’s AI bar.

As you learn, you’ll navigate choices between open-source and proprietary models, cloud and on-prem, small experiments and production systems - the same trade-offs discussed in perspectives like NVIDIA’s view on the future mix of open and proprietary AI. The more fluent you become in those choices, the easier it gets to read any chalkboard list, spot what’s missing, and decide which bottle - or Belgian AI role - you actually want to reach for next.
