Maarten Weyn co-founded CrowdScan in 2020 alongside Ben Bellekens, Stijn Denis, and Anton Dierickx. The technology is based on six years of research at the University of Antwerp and imec, where the founders developed wireless sensor-based crowd density measurement as academic researchers before commercializing it.
Across these posts, Maarten Weyn keeps returning to the same move: take a public claim about science, innovation or policy, go find the primary data behind it, and show where the claim and the data diverge. He does this with a government report on wildfire risk , with the White House's "Science: A New Golden Age" , with the European Innovation Scoreboard , and with a Zoom executive's op-ed on digital sovereignty . The consistent diagnosis is that knowledge and decisions live in separate worlds, and that public debate runs on numbers stripped of their context.
Over the period covered, this hardens from diagnosis into proposal. On the question of valorising fundamental research he notes his own shift: "Vroeger reageerde ik daar defensief op. Nu niet meer." The later posts pair the debunking with a concrete alternative, whether that is a funding structure , a new research-evaluation framework , or a reading of what actually makes CLOUD Act jurisdiction bite .
Weyn's recurring complaint is that evidence exists but never reaches the table where it would matter. On the report that preceded the Hoge Venen fires: "De kloof tussen kennis en beslissing is ouder en breder dan deze brand." He locates part of the blame with his own profession, "Wij wetenschappers publiceren te vaak voor elkaar" , and points out why prevention loses the argument by default: "Preventie levert baten op die onzichtbaar blijven, want een ramp die niet plaatsvindt haalt de krant niet." The same instinct for testing rhetoric against practice drives his reading of the US science policy report, where he asks the one question a policy document has to survive, "do its authors act on what they preach?" , and concludes "I found six contradictions." Applied to the European Innovation Scoreboard, the pattern repeats: "Alle drie de conclusies bevatten een kern van waarheid. Alle drie zijn, zonder context, misleidend."
Asked how to valorise fundamental research, Weyn's answer is to protect the source rather than only optimise the endpoint: "Een keten valoriseert pas ten volle als haar bron blijft stromen." His concrete proposal is two-sided: "Blijf breed en bottom-up investeren in vrij fundamenteel onderzoek. En bouw daarnaast gerichte kanalen die veelbelovend werk sneller naar valorisatie trekken. Een pull, geen push." He finds the same logic confirmed in Astro Teller's moonshot method at Google X, summarising it as "Niet gokken op nummer 17, maar kaarten tellen" , and extends it directly to research funding: "Niemand kan vooraf voorspellen welke fundamentele vraag de doorbraak van morgen wordt."
With RISE at University of Antwerp, Weyn frames evaluation as a break from ranking-driven audit culture. The project chooses "Niet vanuit controle. Niet vanuit scores of rankings" and instead asks "welke omgeving hebben onderzoekers nodig om excellent, betekenisvol en impactvol onderzoek te kunnen doen?" He is explicit that this is a process, not a verdict: "Het is geen eindpunt, maar een dialoog."
Responding to a Zoom executive's claim that sovereignty is not about server location, Weyn splits the difference deliberately: "hij heeft volgens mij half gelijk, en dat halve ongelijk is net het probleem." His point is that legal jurisdiction, not geography, decides the outcome, and without addressing that gap, "Dan blijft soevereiniteit op papier staan."
On the Cafépraat podcast, Weyn talks about the Brewery, the small stage he runs at the Nerdland Festival that pairs good beer with science and nerd culture, and describes how the collaboration with co-host Lieven Scheire started after the two met at the festival four years earlier and decided to build the stage together 17. This origin story and the framing of science-plus-beer as a deliberate format do not appear in the written posts, where his public engagement work is represented instead by the Ig Nobel watch party .

Maarten Weyn discusses the Brewery, a small stage at the Nerdland Festival that combines beer, science, and nerd culture, explaining it as a platform where people can enjoy good beer while engaging with scientific and nerdy topics. He also describes how he and co-host Lieven Scheire met at the Nerdland Festival four years ago and decided to collaborate on the Brewery stage together, with their partnership being facilitated by shared interests in beer, science, and the festival itself.
