Thibaud Elziere

The through-line

Across two decades of ventures, Thibaud Elzière keeps returning to the same question: what actually counts as entrepreneurship, and what separates it from simply taking risk or running a business. He traces this explicitly to Schumpeter's idea that the entrepreneur is not "ni un propriétaire, ni même nécessairement un patron" but a function, the person who introduces a "nouvelle combinaison" into the economy [2][4]. This preoccupation has moved with him as his own activity has diversified from tech (Photolia, HEXA's startup studio) into hospitality and real estate (Iconic House, Side House, WAT, KAFET), and he now tests the definition against his own newer projects, wondering openly whether opening a restaurant or launching a fund really qualifies [2][4]. The shift over time is less a change in belief than an expansion of the domains he applies it to, alongside a growing impatience with slogans that flatten entrepreneurship into either 24/7 grind or pure money-chasing, which he says pushed him to spend ten years thinking about writing a book that shows what actually happens behind the scenes [18].

On entrepreneurship as a function

Elzière's clearest theoretical statement is his adoption of Schumpeter's "nouvelle combinaison": the entrepreneur "introduit dans l'économie une nouvelle" combination, whether a new product, method, market, or way of organizing [2]. He frames this against a looser popular definition built on risk-taking and independence alone, insisting "instinct was that something was missing from the definition," something closer to "creative energy" and "creating something that did not exist before" [4]. The point recurs as a live question rather than a settled answer, he raises it as a discussion starting point at Café de Paris rather than a conclusion, testing it against his own restaurant and fund projects [2][4].

On building physical places

A large share of his current output is about creating spaces people gather in, and he describes each one with the same insistence on hospitality and accessibility. WAT.BXL is pitched against the idea that a tech incubator amid social housing is "un affront fait aux habitants du quartier," a claim he says he thinks "exactement le contraire" of, framing tech and entrepreneurship as "des plus puissants moteurs d'ascension sociale" and running free No-Code stages for neighborhood kids [8]. The same beta space he describes as chaotic and improvised, "il fait toujours un peu trop froid... on bricole. On s'adapte," yet charged with "une énergie de dingue" that reminds him of San Francisco [12]. KAFET, the planned restaurant in the old Imprimerie building, is conceived as "un diner américain des années 50 repensé pour aujourd'hui: plus sain, plus contemporain, mais toujours généreux, simple et accessible," open to everyone from breakfast to dinner [1]. In luxury hospitality, Iconic House rests on the conviction that "la maison pouvait devenir l'expression la plus aboutie du luxe," with the sector's center of gravity moving "de l'hôtel vers la maison. Du spectaculaire vers l'émotion... Du parfait vers le vrai" [13].

On AI and building companies

He treats AI less as a topic and more as a structural shift in how work and companies get organized. Yousign's evolution into Youtrust is explained through a world "où des agents IA signent, négocient, déclenchent des workflows et exécutent des transactions" [10]. In insurance, he cites Sequoia's view that brokerage is "la plus grande opportunité mondiale de services à transformer grâce à l'IA," describing brokers who spend "près de 70% de leur temps sur de l'administratif" and framing the change as one where "le logiciel exécute, l'humain pilote" [11]. He distinguishes genuine "AI Native" companies from those merely using AI to go faster, pointing to Verso as a company that rebuilt its workflow entirely around agents, cutting a six-week consumer study down to 72 hours [14]. He is far more skeptical about AI-generated writing itself, comparing it to Instagram's Valencia filter and asking people to "stop sending AI-generated emails and memos that are twice as long as they need to be and say half as much" [6].

On mentors and countering startup myths

Elzière names Paul Graham as the closest thing he has had to a mentor, crediting him with shaping "l'importance du produit," "la place du CTO," "l'obsession de résoudre de vrais problèmes," "la vitesse d'exécution," and "l'équilibre entre investisseurs et fondateurs" across a generation of founders [15]. This sits alongside his stated reason for writing his book, a reaction against "radical and simplistic narratives about entrepreneurship on social media" such as the claim that founders must work 24/7 or that money is the primary driver, which he wanted to counter with his own lived experience [18].

From the stage

In interview, he gives concrete numbers and reasoning not found in his written posts: Photolia, his crowdsourced image bank launched around 2004, was sold to Dailymotion for 800 million dollars after ten years [17]. He explains that Iconic House is financed through borrowing rather than external investment, a deliberate contrast with how he built his tech companies [17]. On HEXA, he states the studio has created 30 companies, three of them unicorns, and frames this as dramatically improving the odds of startup success compared to normal founding paths [16]. He also raises, without resolving, the question of what actually drives entrepreneurs to build repeatedly, wondering aloud whether it is "dopamine addiction, childhood trauma, or desire for impact," while noting that the successful founders he has observed shared complete focus on their business during the first three years [16].

Takeaways

• He defines entrepreneurship through Schumpeter's "nouvelle combinaison" rather than through risk or ownership alone, and applies this test to his own newer restaurant and fund projects [2][4].
• WAT.BXL's free No-Code stages for local children are framed as a direct rebuttal to the claim that a tech incubator in a social-housing neighborhood is exclusionary [8].
• Yousign's growth from 2M€ revenue in 2018 to over 40M€ in 2025, and its rebrand to Youtrust, reflects his thesis that AI agents will increasingly sign, negotiate and execute transactions [10].
• He holds up Verso as a rare truly "AI Native" company, citing its cut of a six-week consumer study to 72 hours as the kind of full workflow rebuild most companies only claim to do [14].
• Photolia's sale to Dailymotion for 800 million dollars after ten years is the concrete tech success he points to before pivoting into real estate and hospitality financed by borrowing rather than outside investors [17].
• His book "Les pieds sur terre, la tête dans les étoiles" was written to counter what he sees as radical, simplistic social-media narratives about entrepreneurship, such as the 24/7 work myth [18].
