Marcel Duijvestijn

Marcel Duijvestijn's central conviction, repeated across the conversation, is that in SaaS standing still is the same as dying: "In Saas is groei geen keuze. Want als wij niet groeien, ja, dan komt er iemand anders voorbij en die druk je de markt uit." ¹ That belief shapes everything he says about Blue10's steady 15-25% year-on-year growth and his refusal to chase the single-feature arms race that defines much of the invoice-processing market. He is blunt that scan-and-recognize technology, the historic core of his product category, is now worthless as a differentiator: "Als je je nog wil onderscheiden op herkenning, dan gaat er iets niet goed. Dat is water uit de kraan, dat moet gewoon werken." ¹ For a founder who built one of the field's early proprietary neural networks — "Wij hadden al een eigen neuraal netwerk in 2017 voor de herkenning van facturen" ¹ — this is a striking admission that yesterday's edge is today's baseline, and it explains why he keeps steering the conversation toward the approval process, data, and spend management as the places where real value now lives.

That same instinct for where value actually sits shows up in his account of automation and trust. Duijvestijn doesn't want full invisibility even when Blue10 automates matching completely; users need to feel oversight, not just receive an outcome. His Tesla analogy captures this precisely: "Eigenlijk zit hier nu op de autopilot van Tesla. Dus je gaat laten zien wat de bandbreedtes zijn en maar je geeft mensen nog het gevoel dat ze zelf aan het stuur zitten. En we gaan langzaam maar zeker toe naar autonoom." ¹ Reliability, in his view, is invisible until it fails, which is why he insists "de performance is eigenlijk de belangrijkste feature en die wordt pas gemist als die er niet is" ¹ — a line that doubles as an implicit critique of vendors who market flashy features while performance quietly erodes.

Duijvestijn is equally direct about market incentives that work against automation. He argues accountants face almost no pressure to modernize because clients need them regardless of efficiency, and the cost of that inefficiency is simply absorbed by the client's business rather than the accountant. Meanwhile he flags a coming structural shift for Dutch SMBs: software will overtake most line items to become the second-largest cost after personnel within three years, with many companies unknowingly overpaying by hundreds of thousands of euros because of unused licenses and inactive users ¹. This is where his ambition to make Blue10 more of a data company becomes concrete — he floats the idea of a stripped-down scan-recognize product under a separate label, not to compete on features but purely to harvest more invoice data points feeding the core insights business ¹.

On strategy, his sharpest opinions concern consistency versus feature-chasing. He describes the trap where a prospect in a sales process will always surface one missing feature, and the only way out is to stop competing on that axis altogether by solving a bigger problem — which is why Blue10 went multi-product at roughly €5 million ARR, earlier than the €10 million threshold Jason Lemkin advises ¹. He contrasts Exact's repeated strategic pivots unfavorably with AFAS's single, consistent course, arguing that switching costs inside organizations are so large that constancy itself becomes a competitive advantage ¹. He's also candid that American SaaS playbooks from figures like Lemkin and Jacco van der Kooij translate directionally to the Dutch market but not numerically — the absolute figures usually need to be halved or quartered ¹. And he's unsentimental about partner channels: because SaaS companies want frictionless self-service onboarding while implementation partners are paid by the hour and thus incentivized toward complexity, Blue10 stopped using partners for implementation back in 2017, keeping them only as lead generators, and even introduced a paid onboarding fee once he recognized that giving it away for free had been undervaluing a service that measurably reduces churn among low-adoption young customers ¹.

The acquisition story is where his self-critique is most vivid. He calls the deal, with evident rueful humor, "onze duurste MBA die ooit iemand gaat doen" ¹, and the specifics back up the label: a startup's proof of concept looked nothing like a product built for customers expecting a stable platform, so the acquired contract-management technology had to be rebuilt almost from scratch, stretching what was meant to be a 2.5-year payback into something closer to five or six years ¹. He treats this less as a one-off failure than as a structural lesson about how new product development has to be organized — it must sit outside the normal management line, echoing what he frames as Paul Graham's founder-mode versus manager-mode distinction, or it gets smothered by the existing organization's priorities ¹. Operationally, that lesson has hardened into a discipline: Blue10 built a repeatable twelve-week pipeline for new accounting-system integrations, validated with Exact Bouw, with the goal of shipping one new integration per quarter through 2026 specifically to unlock vertical and industry-specific focus ¹.

Perhaps the most personal thread running through the piece is his account of learning to lead people rather than just plans. He names it directly as his biggest lesson as CEO: "Ik kan zelf wel al 10 stappen vooruit zijn, maar als ik dan omkijk en er is niemand met me meegelopen, dan heeft het niet gewerkt." ¹ Strategic clarity, in other words, is useless without socio-emotional buy-in, and he describes having to learn to trust his team, let go of control, and resist the urge to react to every signal immediately ¹. That thinking feeds his closing practical advice: start a leadership development program for your management team earlier than feels necessary, because understanding each other's drives and behavioral patterns makes the team dramatically more effective ¹ — a recommendation that reads less like generic leadership advice and more like something he wishes someone had told him sooner.
