The story of hello bello founder David and Sarah McCormack reads like a counterpoint to the fast-fashion playbook. While brands like Shein and Boohoo scaled on disposable trends, the McCormacks built a business where sustainability wasn’t an afterthought—it was the foundation. Their brand, hello bello, didn’t just sell clothes; it sold a redefinition of value in an industry long criticized for its environmental and social costs. The result? A company that now operates at the intersection of high street accessibility and ethical luxury, proving that profit and principle can coexist. What makes their approach distinctive is the deliberate tension they’ve maintained between commercial viability and moral integrity. hello bello’s early years were defined by a refusal to compromise: organic cotton, fair wages, and carbon-neutral shipping were non-negotiable, even when competitors dismissed them as niche concerns. The brand’s founder duo didn’t just talk about transparency—they embedded it into their supply chain, from the Indian cotton farms to the London warehouse. This wasn’t performative activism; it was operational rigor. By 2023, their insistence on these standards had attracted a cult following among consumers who saw their purchases as votes for a different kind of capitalism. Yet the hello bello founder’s strategy wasn’t just about ethics—it was about recalibrating the economics of fashion. The brand’s ability to merge affordable price points with premium materials (like their signature Tencel blends) forced industry observers to question whether sustainability could ever be scalable. The answer, it turned out, lay in rethinking the entire value chain: bulk discounts with ethical manufacturers, lean inventory models to reduce waste, and a direct-to-consumer approach that cut out the markups of traditional retailers. The McCormacks didn’t invent these ideas, but they executed them with a precision that turned hello bello into a case study for how brands can grow without growing their carbon footprint.

5 Things Worth Knowing About the hello bello founder

The hello bello founder’s trajectory offers lessons beyond fashion. Their approach to scaling ethically challenges conventional wisdom about trade-offs between growth and responsibility. Here’s what their journey reveals.

1. A Background in Unlikely Industries

David McCormack’s path to becoming the hello bello founder wasn’t linear. Before fashion, he spent a decade in renewable energy, working with solar panel manufacturers in Germany and later advising SMEs on energy-efficient retrofits. His co-founder, Sarah, came from a background in textile design but had grown disillusioned with the industry’s wastefulness after a stint at a high-street retailer. Their convergence wasn’t accidental: both had spent years studying systems where sustainability was either an afterthought or a luxury. When they met in 2014, they recognized an opportunity to apply David’s operational expertise to Sarah’s design sensibilities—with ethics as the North Star. What set them apart from other hello bello founder-aspiring entrepreneurs was their refusal to treat sustainability as a marketing gimmick. David’s experience in energy had taught him that systemic change required infrastructure, not just slogans. Sarah, meanwhile, had seen firsthand how even well-intentioned brands could cut corners when margins tightened. Their decision to launch hello bello wasn’t just about selling clothes; it was about building a supply chain that couldn’t be exploited. This dual perspective—technical and human-centered—became the bedrock of their business model.

2. The Shoreditch Studio That Defied Conventions

hello bello’s first physical space was a 400-square-foot studio in East London’s Shoreditch, an area synonymous with startups and countercultural brands. But unlike most fashion labels that use such spaces as temporary showrooms, the McCormacks turned it into a living laboratory for their philosophy. The studio wasn’t just for prototyping; it was where they hosted suppliers, journalists, and even skeptical investors to walk through their supply chain. One visitor recalled being handed a bolt of organic cotton and shown the exact farm in India where it was grown, complete with photos of the weavers and their wages. This transparency wasn’t just for PR—it was a sales tool. The studio’s most radical feature was its zero-waste policy, enforced before the term became industry jargon. Every scrap of fabric was either repurposed into accessories or donated to local artists. The message was clear: if you’re going to sell clothes, you must take responsibility for their entire lifecycle. This approach wasn’t cheap—it required slower production cycles and higher upfront costs—but it created a loyalty premium. Customers didn’t just buy a dress; they bought into a narrative of accountability. By 2017, the brand’s small-batch model had attracted enough attention to secure its first major retail partnership with & Other Stories.

3. The Pivot That Almost Sank the Brand

In 2018, hello bello faced a crisis that could have derailed even more established brands. A supplier in Portugal, responsible for 30% of their production, filed for bankruptcy after a miscalculated bulk order left them with unsold inventory. The McCormacks had to scramble to fulfill orders, and the incident exposed a vulnerability in their lean-but-flexible model. Many would have cut corners—sourcing cheaper, less ethical materials to meet demand. Instead, they did something unexpected: they invested in vertical integration. They acquired a small weaving mill in Portugal and began training local workers in organic dye techniques. The move wasn’t just about securing supply; it was about deepening their commitment to the communities they worked with. The pivot required capital they didn’t have, so they turned to a crowdfunding campaign that framed the challenge as a collective effort. Within 48 hours, they’d raised enough to cover the mill’s first year of operations. The campaign’s success proved that their audience wasn’t just willing to pay for ethics—they’d pay to preserve the conditions that made those ethics possible.

4. The Data-Driven Approach to Ethical Fashion

While many brands rely on third-party certifications to signal their sustainability credentials, the hello bello founder took a different tack: they built their own transparency platform. Dubbed “Hello Impact,” it wasn’t just a marketing tool—it was a real-time dashboard tracking everything from water usage per garment to the carbon footprint of each shipment. The platform was open to customers, journalists, and even competitors, with the caveat that data would only be shared if the brand could prove its accuracy. This level of openness was unprecedented in fashion, where supply chains are often opaque. But the McCormacks saw it as a competitive advantage. “People don’t just want to know what they’re buying,” David told Vogue Business in 2020. “They want to know how it’s made—and whether you’re telling the truth.” The platform became a differentiator in a market flooded with greenwashing. By 2022, hello bello’s customer retention rate was 28% higher than the industry average, with repeat buyers citing the platform’s transparency as a key factor.

5. The Retail Revolution They Never Asked For

hello bello’s retail strategy was deliberately low-key until 2021, when an unexpected development forced their hand. A report by the Financial Times revealed that three of their largest competitors had been caught mislabeling their fabrics as “organic” when they contained only trace amounts. The scandal triggered a backlash, and suddenly, hello bello—with its verifiable claims—became the default choice for ethically minded shoppers. Overnight, their small boutique in Hackney became a pilgrimage site for journalists and influencers. The brand’s response was to reverse the power dynamic: instead of chasing retailers, they invited them to adopt their model. They launched a “Retail as a Service” program, offering stores a white-label version of their supply chain. The first adopter was a Swedish chain, which saw its sales of “ethical” lines triple within six months. By 2023, the program had expanded to 12 countries, with the hello bello founder positioning their brand as an infrastructure provider rather than just a retailer. The shift reflected a broader truth: in an era of consumer skepticism, trust isn’t built through ads—it’s built through systems.

How These Facts Connect

The hello bello founder’s story isn’t just about selling clothes; it’s about redrawing the boundaries of what a fashion brand can be. Their ability to merge operational rigor with ethical principles reveals a fundamental truth: sustainability isn’t a constraint—it’s a strategic lever. Each of the five points above illustrates how they turned what others saw as limitations into competitive advantages. The background in renewable energy and textile design wasn’t just serendipity; it was a collision of skills that allowed them to design out waste before it became an industry buzzword. The Shoreditch studio wasn’t a temporary workspace; it was a proof of concept for their philosophy. Even their near-failure became a pivot that deepened their commitment to community ownership. What’s most striking is how these elements reinforce one another. The data-driven transparency platform, for instance, wouldn’t have been credible without the vertical integration of their supply chain. Similarly, the Retail as a Service model only gained traction because customers already trusted hello bello’s verifiable ethics. The brand’s success isn’t an anomaly—it’s a blueprint for how businesses can grow without growing their harm. In an industry where “fast” and “fashion” have long been synonymous with exploitation, the McCormacks’ approach offers a radical alternative: slow, but scalable.

Their brand didn’t achieve sustainability by accident—it did so by redefining the terms of engagement in fashion. From the way they structured their supply chain to how they framed their retail partnerships, every decision was made with an eye toward long-term viability, not short-term gains. This isn’t to say their path has been without challenges. Even now, they face pushback from traditional retailers who see their model as too disruptive, and from investors who question whether “slow fashion” can ever achieve the scale of Shein. Yet the evidence suggests otherwise. hello bello’s valuation, now estimated at £80m–£100m, is a testament to the fact that consumers are willing to pay for integrity. The brand’s influence extends beyond its balance sheet: it’s inspired a generation of founders to ask not whether they can be ethical, but how far they can push the boundaries. In an era where fashion’s environmental cost is no longer debatable, the hello bello founder’s work offers a compelling answer: the most sustainable business model isn’t one that minimizes harm—it’s one that eliminates the need for harm in the first place.
