How to embed sustainability into unit economics, how to stay true to your mission, being an impact entrepreneur in a short-termist and finance-first World<\/em><\/strong><\/h3>\n\n\n\n

How should founders embed sustainability and impact into their business models \u2014 not as compliance overhead, but as genuine competitive advantage \u2014 at a time when ESG regulation is tightening and investors\u2019 appetite for \u201cimpact premiums\u201d is fading? Taking into account that public money and Government subsidies is not a sustainable business model any more, even if you think it has ever been one.<\/strong><\/p>\n\n\n\n

This is no longer only a philosophical question. It\u2019s an operational one.<\/p>\n\n\n\n

Over the past weeks, I sat down with 11 battle-tested founders across climate, circular economy, fintech, health, education, and civic tech to pressure-test a simple idea: when does impact actually translate into ROI?<\/em>
<\/em>I listened. I challenged. I compared execution patterns.<\/p>\n\n\n\n

This piece also builds on more than a hundred long-form interviews I\u2019ve conducted since 2021 for my podcast 40 Nuances de Next<\/em> \u2014 an unusually rich archive of founders speaking openly about what works when sustainability meets the P&L.<\/p>\n\n\n\n

What follows is not a manifesto. It\u2019s a field guide.<\/p>\n\n\n\n

Lesson 1 \u2014 Impact must live in unit economics, not in deck appendices<\/strong><\/h3>\n\n\n\n

The first and most brutal pattern: if impact does not improve your unit economics, it will eventually be cut.<\/strong><\/p>\n\n\n\n

Paolin Pascot, founder of Agryco (former Agriconomie), put it plainly: \u201cWe\u2019re building regenerative agriculture supply chains. But if the economics don\u2019t work for farmers and buyers simultaneously, it\u2019s just a nice PowerPoint.\u201d<\/em><\/p>\n\n\n\n

Agryco doesn\u2019t sell \u201cregeneration\u201d as a moral add-on. It embeds carbon sequestration into yield improvement and supply-chain resilience. Sustainability is not a cost line \u2014 it\u2019s the mechanism that stabilizes margins on both sides of the market. Hortense Harang, at Fleurs d\u2019Ici (We Trade Local), applied the same logic to flowers: \u201cWe don\u2019t compete on \u2018being local\u2019 as a feel-good story. We compete because hyper-local sourcing reduces waste, improves freshness, and creates defensible relationships with growers. The impact is real, but so is the business case.\u201d<\/em><\/p>\n\n\n\n

Here\u2019s the rule most decks still avoid: customers don\u2019t pay for virtue; they pay for performance.<\/strong>
<\/strong>If sustainability doesn\u2019t improve quality, reliability, or cost structure, it will not survive scale.<\/p>\n\n\n\n

Lesson 2 \u2014 Product superiority beats moral storytelling<\/strong><\/h3>\n\n\n\n

Marta Sj\u00f6gren, CEO of Paebbl, crystallizes the hard truth of climate tech: \u201cClimate tech only scales if it\u2019s economically inevitable. We\u2019re mineralizing CO\u2082 into building materials \u2014 but we win because our product performs better and costs less than alternatives, not because customers want to save the planet.\u201d <\/em>This is the dividing line between scalable climate tech and subsidized experiments.
Paebbl doesn\u2019t ask buyers to compromise. It removes the trade-off entirely. The carbon story matters \u2014 but only because the product already wins on physics and pricing.<\/p>\n\n\n\n

Impact that depends on customer goodwill is fragile.<\/strong>
<\/strong>Impact that rides on product superiority compounds.<\/strong><\/p>\n\n\n\n

Lesson 3 \u2014 Expand the stakeholder map or stall<\/strong><\/h3>\n\n\n\n

The second major insight: impact often creates value \u2014 but in the wrong budget.<\/strong><\/p>\n\n\n\n

Maxime Leroux, founder of ClimateView, learned this the hard way: \u201cWe went from targeting environmental departments to engaging transport, budget, and economic development departments. Climate action planning touches everyone\u2019s budget \u2014 you just need to quantify it in their language.\u201d<\/em>
<\/em>By reframing climate action as infrastructure planning, ClimateView unlocked a much broader buyer universe.
Same product. Different translation.<\/p>\n\n\n\n

Rachel Delacour, CEO of Sweep, applies the same principle in large corporations: \u201cCarbon accounting isn\u2019t just an ESG compliance exercise. It\u2019s supply chain risk management, operational efficiency, and investor relations. The moment you reframe it as business intelligence, every CFO pays attention.\u201d<\/em><\/p>\n\n\n\n

Impact doesn\u2019t fail because it has no value.<\/strong>
<\/strong>It fails because founders don\u2019t know how to price that value across stakeholders.<\/strong><\/p>\n\n\n\n

Lesson 4 \u2014 Control your destiny before you maximize impact<\/strong><\/h3>\n\n\n\n

Axel Dauchez, founder of Make.org, speaks openly about a tension many impact founders avoid naming: \u201cThere are moments when business is subordinated to mission because you\u2019re at the end of an investment cycle \u2014 you need others to survive. At that moment, your priority is business survival.\u201d <\/em>
<\/em>He goes further: \u201cWhen you find yourself in control of your destiny \u2014 when the business is there \u2014 your priority becomes maximizing impact.\u201d<\/em><\/p>\n\n\n\n

This is uncomfortable, but accurate.<\/p>\n\n\n\n

Selling below cost while claiming moral superiority is not impact \u2014 it\u2019s dependency.
Only companies that control their cash trajectory can afford to push their mission fully.<\/p>\n\n\n\n

Lesson 5 \u2014 Internal coherence is an impact KPI (KAPI*)<\/strong><\/h3>\n\n\n\n

Dauchez adds a rarely discussed dimension: \u201cYou can\u2019t sustain internal dissonance between what people experience in their guts and what they tell their families. If you don\u2019t address this with your team, there is huge internal suffering.\u201d<\/em><\/p>\n\n\n\n

Impact is not only external.
When the company narrative diverges from daily reality, teams feel it immediately.<\/p>\n\n\n\n

This is where transparency becomes operational, not ideological.<\/p>\n\n\n\n

Lesson 6 \u2014 Radical honesty beats inspirational fiction<\/strong><\/h3>\n\n\n\n

Axel Dauchez practices brutal clarity: \u201cHave we really solved the problem of women\u2019s violence? No. Are we up to the task? No. Did we do good things? Yes.\u201d <\/em>And then the line most founders avoid: \u201cThe \u2018everything is great\u2019 speech often hides the discomfort that people feel.\u201d<\/em>
<\/em>Nicolas Reboud, founder of Shine, echoes this restraint: We built tools that genuinely reduce administrative burden for small businesses. That\u2019s real impact \u2014 but we don\u2019t pretend we\u2019ve fixed France\u2019s entrepreneurship ecosystem. We fixed one pain point well.\u201d<\/em><\/p>\n\n\n\n

Impact credibility grows when ambition is precise and limits are explicit.<\/strong><\/p>\n\n\n\n

Lesson 7 \u2014 Impact is often organizational, not Thematic<\/strong><\/h3>\n\n\n\n

Lo\u00efc Soubeyrand, founder of Swile, reframes impact through execution quality: \u201cMy personal fight is making work better. Most workplace unhappiness comes from dysfunctional organizations.\u201d<\/em><\/p>\n\n\n\n

This is not glamorous impact. It doesn\u2019t photograph well. But it touches millions of daily experiences \u2014 and it directly affects retention, engagement, and performance.<\/p>\n\n\n\n

Sometimes the most scalable impact is simply running a better company<\/strong>.<\/p>\n\n\n\n

Lesson 8 \u2014 Reject the profit vs impact dichotomy : Ecology is Economy\u2026 and vice versa.<\/strong><\/h3>\n\n\n\n

Mathieu Nebra, co-founder of OpenClassrooms, dismisses the framing altogether: \u201cCommon sense doesn\u2019t need to adapt to certain terms. If you think something is important, just do it. Impact is a slogan \u2014 what matters is doing things correctly.\u201d <\/em>
<\/em>He adds:\u201cThere are two unique modern challenges \u2014 environmental crisis at unprecedented scale and global inequality. But the fundamental nature of entrepreneurship hasn\u2019t changed: solve real problems for real people.\u201d<\/em><\/p>\n\n\n\n

This is not na\u00efve. It\u2019s disciplined.<\/p>\n\n\n\n

Lesson 9 \u2014 When business case and impact case are aligned (ie identical)<\/strong><\/h3>\n\n\n\n

Eric Carreel, founder of Withings (and Fifteen), applies this logic to health tech: \u201cWe make devices that help people understand their health. The impact is obvious \u2014 but we don\u2019t position it as charity. We position it as essential infrastructure for preventive healthcare.\u201d<\/em><\/p>\n\n\n\n

Preventive health is impact. It\u2019s also a massive market inefficiency waiting to be corrected. When impact aligns with structural demand, pricing power follows.<\/p>\n\n\n\n

Lesson 10 \u2014 Start from problems worth solving<\/strong><\/h3>\n\n\n\n

Pascal Lorne, who recently exited GoJob, summarizes a decade of execution: \u201cWe succeeded because we started from problems worth solving \u2014 education, employment access, social inclusion \u2014 not from what was technically flashy or fundable.\u201d<\/em><\/p>\n\n\n\n

Impact here is not branding. It’s a strategic focus.<\/p>\n\n\n\n

Lesson 11 \u2014 The investors\u2019 rule of thumb<\/strong><\/h3>\n\n\n\n

After listening to these founders, a pattern becomes unavoidable:<\/p>\n\n\n\n

The only impacts that scale are those that do at least one of the following:<\/strong><\/p>\n\n\n\n

    \n
  1. structurally improve unit economics<\/li>\n\n\n\n
  2. reduce operational or regulatory risk<\/li>\n\n\n\n
  3. compress acquisition, retention, or financing costs<\/li>\n<\/ol>\n\n\n\n

    Everything else is storytelling.<\/p>\n\n\n\n

    What you should do Next <\/strong><\/h3>\n\n\n\n
      \n
    • Embed impact in unit economics.<\/strong> If sustainability doesn\u2019t improve margin, redesign the product.<\/li>\n\n\n\n
    • Translate impact across budgets.<\/strong> Learn to sell risk reduction, efficiency, and resilience \u2014 not ideals.<\/li>\n\n\n\n
    • Control your cash trajectory.<\/strong> You can\u2019t maximize impact while economically fragile.<\/li>\n\n\n\n
    • Practice radical transparency.<\/strong> Credibility compounds faster than inspiration.<\/li>\n\n\n\n
    • Reject false dichotomies.<\/strong> Profit and impact are not enemies \u2014 confusion is.<\/li>\n\n\n\n
    • Build for inevitability.<\/strong> Anchor strategy in physics, prices, and real constraints \u2014 not regulatory moods.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Synthesis<\/strong><\/h3>\n\n\n\n

      In 2026, impact entrepreneurship is no longer about choosing between mission and money.
      It\u2019s about building companies where economic value and social or environmental value reinforce each other structurally<\/strong>.<\/p>\n\n\n\n

      Markets don\u2019t reward virtue.
      They reward inevitability.<\/p>\n\n\n\n

      As Lo\u00efc Soubeyrand puts it: \u201cWhen you improve organizational excellence, you improve happiness at work \u2014 which is a big part of everyone\u2019s day. That\u2019s impact that drives business performance.\u201d<\/em><\/p>\n\n\n\n
