Jasper Dockx
Ben Deconinck interviews Jasper Dockx, founder of Antwerp social-first agency Twaalfde Man, two years after his first appearance. Jasper describes how choosing a target-audience niche (young people via social media) instead of a sector niche unlocked rapid growth, landing Hubo, Burger King, Duvel Moortgat and Bednet, and how a self-funded market study of 2,000 Belgian youngsters plus a weekly no-sales newsletter turned prospects into inbound fans (9 of 10 sales meetings are inbound). He argues the classic marketing funnel is dead, that 6 in 10 young people search TikTok before Google, and that authentic UGC and platform-native content beat polished ads. He also opens up about agency economics (billability, ~20% margins, pricing on value), AI tooling, and a brutally honest account of losing two employees, cancelling his holiday and working 7 days a week through the loneliest period of his career.
Insights & takeaways
Jasper Dockx's thinking centers on one repeated claim: young people no longer relate to brands the way marketing textbooks assume. "Gen Z is geen klant van een merk," he says, "als je aan een Gen Z'er vraagt waar zij gij klant, zou je zeggen: huh, klant? Als je aan Gen Z vraagt van welk merk zij gij fan, dan beginnen die" 12. That distinction between customer and fan runs through everything else he says. Brands cannot simply broadcast a message and expect it to land, because "er staat een muur tussen en op die muur staat: I don't care" 12. His prescription is to stop observing the audience from outside and instead operate inside it: "je moet gewoon in die community staan, je moet er niet naar kijken, je moet erin staan" 12. Practically this means partnering with small, trusted creators rather than dictating terms to them, and asking, as he puts it, "mag ik op uw feestje komen en wat moet ik aan hebben?" instead of telling creators what to do 11.
A second consistent thread is that value, given away for free, is the actual sales engine. Twaalfde Man built its growth by refusing to pitch: "Wij doen nul sales, nooit. De enigste call to action dat wij soms in ons nieuwsbrief zetten is: wilt je meer tips? Volg mij op LinkedIn" 11. He describes the origin of this approach almost by accident, prompted by a client who wouldn't read existing newsletters because "de info gewoon niet goed is, dat het gewoon bagger is," which led him to write one where "de info wel goed is" 12. The payoff, he says, is that most sales conversations now come to him: nine out of ten meetings are inbound, including marketing directors of large brands reaching out on their own initiative 11. This ties to his broader claim that "met die verbinding maak je van klanten fans, wat ja nu echt wel moet" 12 — connection, not persuasion, is what converts.
On platforms, his views have sharpened with data rather than changed direction. Early on he argued TikTok is an entertainment channel that "vervangt een tv, vervangt Netflix" and shouldn't be treated as a sales channel 12. Later posts extend this into concrete numbers: "Daar zegt zes op de 10 dat ze eerder iets opzoeken via TikTok dan Google" 11, and separately, "65% van de jongeren heeft al via TikTok naar een job gezocht" while "57% haakt af bij gepolijste employer video's" . He also tracks a shift back toward longer content, noting that on smart-TVs YouTube now outperforms Netflix and that some of his own talents see over 50% of views coming through smart-TV with completion rates up to 60%, concluding that young audiences are "opnieuw op zoek naar iets om echt in te zitten, iets waar ze tijd voor maken" . Around the World Cup he pointed to the same pattern from a different angle: fans and creators, not official broadcasters, now shape how people experience live events, though he also credits Sporza for adapting by livestreaming matches on YouTube with creators and cutting the footage into snippets afterward . Across these observations his advice to brands is consistent and practical: either collaborate with a creator who already has an audience as the fastest way to test, or produce your own format where the brand is just the backdrop, accepting that it costs more but that a single shoot day can feed weeks of social snippets .
He is equally blunt about production values changing over time. "Zes jaar geleden moest alles gepolijst en grafisch zijn," but today Gen Z prefers lo-fi, relatable creator content over expensive productions, and he distinguishes influencers used for reach and discounts from content creators used to build a brand through repeated, varied, relatable use-cases 12. He prefers micro-influencers with a following in the thousands over celebrities with far larger audiences, arguing their endorsement carries more weight because it is recognizable and authentic to their followers 12. He treats virality itself with suspicion: chasing a trend can get views, but numbers detached from the brand's actual message are wasted, and he insists entertainment content must be paired with something useful and on-message 12.
A recurring personal theme is that starting matters more than planning. Reflecting on buying his first camera "een dag voor mijn eerste opdracht," with "geen plan, geen ervaring en geen portfolio," he draws the lesson that "beginnen is de belangrijkste stap" and that the difference between a month of thinking and a year of thinking is "niets in je resultaat" . He applies the same logic to content output, dismissing people who theorize about strategy while producing "0 posts en geen impact," and describing his own approach as simply posting two to three times a week for years, admitting the results aren't always "on point" but insisting persistence is what built his following — a discipline he says he's now repeating on Instagram and TikTok with a goal of "nog 100 posts online gooien voor het einde van het jaar," even though "dit oncomfortabel voelt" . This bias toward action also shows up in his business posture: "Ik speel om te winnen en niet om niet te verliezen" 11.
Running the agency itself, he is candid that entrepreneurship is often lonely rather than glamorous. When two employees left at the start of summer he described working every day, cancelling travel, and simultaneously living through "super eenzame periode. Super eenzaam, want ik ben enigste. Niemand zit in uw situatie. Niemand" — even as it coincided with his strongest business period yet 11. He treats communication as the core operating skill of running people, saying "communicatie is alles. Daar heb ik heel veel geld en heel veel energie en tijd in gestoken," after learning that direct correction reads to junior staff as anger rather than feedback 11. On money, he separates personal grievance from principle: discussing years of underpaying himself and skipping holidays, he states plainly he has no issue with entrepreneurs paying taxes and is proud of the jobs and impact that come with success, but objects to the assumption that all entrepreneurs are wealthy, noting that many "(te) weinig verdienen en toch verder doen. Uit passie, uit geloof of uit trots" . For him the throughline across content strategy, business building and personal grind is the same: clarity of position, consistent presence, and doing rather than deliberating — captured in his own summary that positio
- Giving away all knowledge for free (ebooks, newsletters, inspiration sessions) eliminates the need for sales meetings: prospects arrive already convinced Twaalfde Man is the ideal partner.
- Gen Z are not customers of a brand but fans; brands must stand inside the community — replying to comments and viral posts — rather than observing it from outside.
- TikTok changes so fast that after four weeks the platform looks different in content format, length and trends; you must engage daily or lose touch entirely.
- Companies wrongly benchmark competitors' content instead of looking from the audience's perspective: the same person uses Instagram and LinkedIn for completely different reasons, so the message must fit the platform intent.
- TikTok competes with Netflix and TV, not with Facebook or Instagram — it's an entertainment channel with average daily usage approaching 1.5 hours, and shouldn't be used as a sales channel.
- Six years ago everything had to be polished and graphic; today high-production ads fail with Gen Z, who prefer lo-fi user-generated content from relatable creators over €30,000 productions.
- For B2B, 'podcast generated content' — faking a podcast setting for ad clips — works because the audience perceives the speaker as invited and valuable rather than selling.
- Distinguish influencers from content creators: use influencers with big reach for product pushes/discounts, but use 10 content creators showing the product in different relatable situations to build the brand.
- Prefer micro-influencers with 5-6,000 followers over celebrities with 100,000: they are authentic and recognizable to their followers, so their endorsement has more impact.
- Jumping on random trends (e.g. employees doing a dance) can get 40,000 views but is useless if viewers can't link the content to what the company actually does.
- Gen Z will pay €2 more for a product if the price increase comes with a transparent, honest explanation of why.
- Instead of niching on a sector (real estate, construction, HR), Twaalfde Man niched on a target audience — 'reaching young people via social media' — which made the pitch one sentence, brought internal focus and drove growth.
- The agency does zero direct selling in its newsletter and content — only value (data report, keynotes, tips) — and as a result 9 out of 10 sales meetings are inbound, including marketing directors of large brands reaching out themselves.
- The classic awareness-interest-conversion funnel no longer works; buying decisions happen in a constant loop of brand touchpoints (TikTok, newsletter, offline, YouTube) that must all tell the same story — Jasper bought a brand's trousers at the very first touchpoint via a YouTube comment.
- 6 out of 10 young people search TikTok before Google when researching purchases, because it's visual, fast, ad-free feeling and comes from real users rather than SEO blog spam.
- For UGC and creator collaborations, first find people who already buy and use the brand's product instead of mailing random creators — authenticity is visible in the content and counters 'flat' commercial UGC.
- Belgian marketing managers still dismissed short video as 'that doesn't sell', and international (US) data wasn't culturally transferable, so Twaalfde Man self-funded its own Belgian market research of 2,000 youngsters to claim a data-driven market position.
- Giving the expensive data report away for free is deliberate: recipients become fans, and since marketing managers change employers every 3-4 years, today's non-buyer becomes tomorrow's client with agency budget.
- Starters should pick one social channel and do it properly rather than spreading across LinkedIn, TikTok, Instagram and a newsletter at once — LinkedIn became Twaalfde Man's biggest sales channel after 8 years of weekly consistency.
- Going viral is not a goal: 100,000 views of three guys dancing in English says nothing about the brand and reaches the wrong country; entertainment content grabs attention but must be paired with useful, on-message content to build the brand.
- To win trust with young audiences in 90 days: split the audience into 4-5 subcultures, partner with small trusted creators (e.g. Twitch streamers with a few thousand loyal viewers), advertise useful content, and ask as a brand 'may I join your party?' rather than dictating.
- An easy first content play for any business: have store staff note the most frequently asked customer questions for a few weeks — if 20 people a day ask it in-store, thousands more are searching it online.
- Agency economics: distinguish overhead from per-employee costs, track billable hours (industry benchmark ~80% billable across the team), add a percentage for project management on every quote (a costly early mistake to omit), and target ~20% pre-tax margin — a strong niche position lets you exceed that.
- Once positioned with big brand references, sales conversations shift from price ('my neighbour does it for €15/hour') to 'when can you start' — positioning removes price pressure.
- AI's real agency value is killing 'shit tasks': shared ChatGPT projects trained per client and Fixer AI drafting follow-up emails and meeting notes free up an estimated 15-40% of some profiles' time for faster client action.
- Working free as a starter is fine if you're transparent: agree deliverables upfront, contractually secure the right to use the work as a reference, and state clearly that the next clients will be paying — portfolio is the single most important asset in creative work.
- The reality of entrepreneurship is lonely: when two employees quit at the start of summer, Jasper worked 7 days a week, skipped every festival and cancelled a three-week Brazil trip, while paradoxically having his best business period ever (Forbes article, Burger King signing).
- Communication is the number one agency skill — he now asks 'what feeling do I want to give this person' before giving feedback, after learning that his direct corrections landed as 'the boss is angry' with junior staff.
- He stopped hiring 'a second Jasper' — with seven Jaspers the company would fold; instead he probes for evidence of the actual competence, e.g. asking project manager candidates about organizing scouting camps.
- If restarting today he would first work 3-4 years at an agency for experience: he had never done a job interview or sales meeting before running his own, and learning finance/HR/sales the hard way cost months of zero profit from underpriced deals.
