Adanola's founder gave up the CEO seat. Revenue grew 48%.

Adanola's founder gave up the CEO seat. Revenue grew 48%. In 2015, Hyrum Cook turned a gap in the leggings market into a Manchester activewear label. Nine years later, mid hyper-growth, he did something few founders choose voluntarily: he hired someone else to run the company he built. - By Remarkable Magazine · SEPTEMBER 05, 2026 - Hyrum Cook - Adanola Most founders who build a company to eight figures in revenue want to run it. Hyrum Cook spent nine years doing exactly that at Adanola, the Manchester activewear label he started in 2015 - and then, in the middle of the fastest growth the company had ever seen, he gave the job to someone else. A gap in the leggings market. Adanola launched in 2015, reportedly co-founded by Cook and his brother Josh, selling leggings into a market Cook saw as split between purely technical gym wear and everyday fashion, with little in between. The brand's Ultimate Leggings became its signature product, with more than a million pairs sold, and its customer base grew alongside a run of celebrity wearers - Kendall Jenner, Kaia Gerber, Rosie Huntington-Whiteley and Veneda Carter among them. By the year to March 2024, Adanola's Companies House accounts showed revenue had more than doubled to £57.1 million, up from £27.9 million the year before, with pre-tax profit of £18.9 million. Cook had been CEO the entire time. Hiring the person who scaled his rival. In April 2024, Adanola announced that Niran Chana would take over as chief executive, effective June 20, 2024. Chana's résumé was specific and pointed: as chief commercial officer at Gymshark - Adanola's most obvious UK rival in the activewear category - he had helped grow that company's revenue from roughly £5 million to £500 million, and had been involved in the 2020 deal in which General Atlantic bought a stake in Gymshark at a valuation above £1 billion. Cook's own explanation of the hire was blunt about why he wanted exactly that experience: "Niran's been there, done that, bought the T-shirt." He was equally direct about what he was keeping for himself. "Stepping into a founder role, I will work very closely with Niran and the wider team and focus on the things that enabled me to found Adanola in the first place, including brand, product, culture, and community," Cook said of the move. He did not frame it as retirement or an exit - Adanola's own trade-press coverage of the appointment described it as a handover of operational control, not of ownership or involvement. It is a specific kind of decision: a founder, still growing fast and still in his thirties, concluding that the skill set that built the company was not the skill set needed to scale it past nine figures - and choosing to bring in someone whose only credential was having done that exact job at a direct competitor. What happened after he let go. The year after Chana took over, to March 2025, Adanola's revenue grew 48% to £84.5 million. Gross profit rose 42% to £57.6 million, even as the gross margin slipped to 68.1% from 71.1% - the kind of trade-off that shows up when a company is spending harder to fund growth. Net profit rose to £16.58 million, up from £14.2 million the year before. Adanola brought in PwC in February 2025 to find outside investors, and in August 2025 the Los Angeles-based private equity firm STORY3 Capital Partners took what the companies called a "significant minority investment," reportedly valuing Adanola at approximately $530 million (around £400 million). The deal closed days before those FY25 numbers were filed with Companies House. Vogue Business, covering the leadership change the year before, had already put the underlying question to readers directly: why would a fast-growing, founder-run brand's own founder choose to hand over the wheel? The accounts suggest an answer that has less to do with sentiment than with capacity. Nine years in, Cook was still the person best placed to shape what Adanola was - the product, the brand, the culture he'd built it around. He was not, by his own account, the person best placed to run the operational machine at £84 million and rising. Deciding those are two different jobs, and that the second one might be better done by someone else, is the part of this story that is actually a decision rather than a resume line.

Now He Wants It Back. - the rival brand Niran Chana left, and the founder who stepped out of the CEO seat once himself before returning to it. * How Dagne Dover's Founders Chose Patient Capital Over VC - a different DTC brand that made the opposite call on outside capital from day one. * Founder Burnout: What the Research Actually Shows - what the data says about the cost of staying in the top job past the point it still fits.

Niran Chana's April 2024 appointment as CEO effective June 20, 2024, his Gymshark background scaling revenue from roughly £5 million to £500 million and his role in Gymshark's 2020 General Atlantic deal, and Cook's "been there, done that, bought the T-shirt" and "stepping into a founder role" quotes, are per trade-press coverage of the announcement, including Drapers and Retail Week. Vogue Business covered the same handover under the headline "Adanola has a new CEO. Why is its star founder handing over?" The FY2025 revenue (£84.5 million, up 48%), gross profit (£57.6 million, margin down to 68.1% from 71.1%) and net profit (£16.58 million, up from £14.2 million) are from Adanola's Companies House filing of September 23, 2025, as reported by FashionNetwork. The February 2025 PwC mandate and the August 2025 STORY3 Capital Partners minority investment at an approximate $530 million valuation are per Adanola's own announcement and coverage by TheIndustry.fashion, Retail Bulletin and FinSMEs.

Gymshark names new chief supply chain officer.

Gymshark names new chief supply chain officer. Matt Rogers joined the fitness apparel brand in 2023 and previously held the role of global supply chain director. Published Aug. 5, 2026 Gymshark named Matt Rogers as its chief supply chain officer, effective Aug. 1, Rogers told Supply Chain Dive in an email. "Matt has consistently demonstrated the leadership, judgement and ambition needed to build a supply chain that's ready for the next chapter of Gymshark," Ben Francis said in a LinkedIn post last week. Rogers first joined Gymshark in 2023 as supply chain director, according to his LinkedIn profile. Per Francis' LinkedIn post, Rogers has been leading the function as interim general manager for sourcing and supply chain. With Rogers leading Gymshark's supply chain functions, the company has reduced its logistics and distribution costs by several millions per year, while making faster deliveries in the U.S. and the U.K, Rogers said. Prior to Gymshark, Rogers worked at Asos as group supply chain director, per his LinkedIn. He also has experience working for House of Fraser, DHL and NYK Logistics. Laurent Madelaine served as Gymshark's chief product and supply chain officer for nearly 4 years before recently announcing his departure in a LinkedIn post. Rogers' new role comes as Gymshark aims to build an omnichannel brand with physical locations across the globe, and has modified and scaled its operation to support such growth, Rogers said. Last year, the company opened its first brick-and-mortar store in the U.S. and also formed its first U.S. wholesale partnership with Dick's Sporting Goods. "It's no secret that our CEO Ben Francis' ambition for Gymshark is to make it a 100-year brand that outlives all of us. As we continue to grow, especially in the US, we need to ensure our supply chain grows with us and fulfils the needs of our amazing, but expectant community," Rogers said.

How to build an exit-ready business (even if you're not planning to sell yet).

How to build an exit-ready business (even if you're not planning to sell yet). Exit readiness is not just for owners planning a sale. Learn how the qualities buyers value most also make a business stronger to own and run today. Most owners treat exit readiness as something to think about when a sale is on the horizon. Until then, it sits on the someday list, behind the demands of customers, staff, and day-to-day trading. Yet plans have a habit of moving faster than expected: research by Evelyn Partners in late 2024 found that 29% of UK owners of businesses turning over £5m or more had accelerated their exit plans in the previous twelve months, up from 23% only eighteen months earlier. In practice, the qualities that make a business easy to sell are the same qualities that make it more resilient, more profitable, and less stressful to run. Building them early means you are never forced to choose between accepting an approach unprepared and turning it away. 1. Reduce the Business's Reliance on You Founder dependence is one of the most common reasons buyers hesitate. If key relationships, decisions, and knowledge all sit with one person, a buyer sees risk where the owner sees dedication. Few founders have demonstrated this more visibly than Gymshark's Ben Francis, who handed the chief executive role to experienced operator Steve Hewitt while still in his twenties, and spent the following years leading brand, product, and technology before returning as CEO in 2021. On his return he reflected: "I'm well aware of the fact that I've got so much more yet to learn, but equally I do feel like everything has led me to this point has put me in such an amazing position to do this role." Stepping back was not stepping away; it was building a business that no longer depended on him. Delegating authority, documenting how things work, and letting the team own client relationships takes time. Started early, it happens gradually and naturally rather than in a rushed and unconvincing way just before a process begins. 2. Keep Your Financial Reporting Clean and Current Buyers place more trust in a business whose numbers are timely, consistent, and easy to reconcile. Messy or backward-looking reporting invites questions, and questions slow deals down. Good management information is not just a diligence asset. It helps you run the business better in the meantime, which is exactly why buyers value it. 3. Broaden Your Customer Base Heavy reliance on one or two customers is a value drag that takes years, not months, to fix. Buyers look closely at what would happen if the largest relationship walked away. Widening the customer mix, securing longer-term agreements where they suit the business, and deepening relationships beyond a single contact all reduce that perceived fragility. 4. Build a Second Tier of Management A capable team beneath the owner reassures buyers that the business will keep performing through and after a transition. It also gives you options: to step back, to grow, or to sell on your own timetable. It is no coincidence that when General Atlantic invested in Gymshark in August 2020, taking a 21% stake at a valuation above £1 billion, the business had a professional leadership team well established around its founder. Announcing the deal, Francis paid tribute to that team directly: "They've helped develop this business into what we see today, and I'm proud to work alongside such an incredibly ambitious, dynamic and humble group of people." Institutional capital arrived once the business demonstrably ran on more than one person. Developing that layer is slow work. Recruiting, trusting, and retaining good people is far easier to do over years than under the pressure of a live process. 5. Understand What Drives Your Value Every sector has characteristics that buyers consistently pay for: recurring revenue, specialist capability, strong margins, a defensible position. Knowing which of these apply to your business tells you where to invest your effort. The sports nutrition brand Grenade is a striking example of value built deliberately over time. Founded by Alan and Juliet Barratt in 2010, the business took private equity investment from Grovepoint, was acquired by Lion Capital in 2017, and was then bought by Mondelez International in March 2021 in a deal widely reported at around £200m, with the founders retaining a minority stake. As Alan Barratt put it at completion: "When Jules and I founded Grenade from our spare bedroom with a budget of US$700, we dreamt of building an iconic brand available globally." Each stage strengthened the platform for the next, and each new investor paid for value the previous stage had built. An occasional, honest review of how a buyer would see your business keeps you focused on the improvements that matter, whether a sale is two years away or ten. In summary An exit-ready business is one that runs without depending on its owner, reports its numbers well, spreads its customer risk, has depth in its team, and knows where its value comes from. None of this requires a decision to sell, and as Gymshark and Grenade show in their different ways, the businesses that command the strongest interest are those that built these foundations long before any transaction. All of it makes the business better today. At La Salle, La Salle Corporate International work with owners well before any transaction, helping them see their business as a buyer would and prioritise the changes that build value. When the right moment does arrive, prepared owners move with confidence rather than scrambling to catch up. If you have questions regarding any stage of the sales process, reach out in confidence and La Salle Corporate International'll be happy to talk you through the process.
