Stuart Machin is the CEO of Marks and Spencer. At sixteen, he was in his first retail job, a Saturday shift at Sainsbury’s stacking shelves and collecting trolleys, earning a hefty £3.80 an hour. What followed was a 30 year journey through every level of retail: Sainsbury’s, Tesco, Asda, Target and Ocado.
He joined M&S in 2018 as MD of Food. In 2019, M&S acquired a 50% stake in Ocado, replacing their incumbent retail partner Waitrose, and Machin became NED of the new JV. In 2021, Machin was given the additional role of joint COO. In 2022, Machin succeeded Steve Rowe as CEO.
On becoming CEO, Machin launched Straight to Stuart, a scheme enabling staff to share views and ideas with him directly for improving the company. A CEO who once pushed trolleys didn’t forget what it felt like to be the person nobody asked, and didn’t want anyone at M&S to feel like that.
The scheme has generated 15,000 suggestions to date, including from bowel cancer survivor Cara Hoofe whose idea for the inclusion of bowel cancer symptoms on toilet roll packaging and in-store toilets was implemented across all M&S stores.
M&S had been underperforming for years, their clothing range ridiculed as tired, stores felt dated and obituaries for a brand that had once defined British retail were drafted. Under his leadership, the company returned to the FTSE100 in 2023 and restored its dividend in 2024.
Machin’s leadership style reads like a case study in intensity, a pace that reflects his broader philosophy on leadership that challenges conventional thinking around balance and detachment. I don’t like all this talk about work-life balance. What I don’t like is leaders going away and completely switching off.
Machin frames leadership as a continuous responsibility. While he acknowledges the need for time away, he expects leaders to remain connected and accountable. That mindset is rooted in a deeper belief that building a business requires total engagement.
Since taking the helm, Machin has engineered one of the most notable retail turnarounds, through relentless operational execution and cultural overhaul. Although M&S has little in common with startups, his leadership mantra provides an insightful blueprint for founders navigating growth, cashflow pressures, investor expectations and market turbulence. Machin’s operating model is built upon three core tenets:
- Proximity to the front line: He routinely spends weekends walking store floors, speaking directly with employees, and personally reviewing customer feedback.
- Positive dissatisfaction: Machin fosters a culture where managers and teams focus primarily on what is broken rather than celebrating milestones. Success is treated as a temporary baseline rather than a final state.
- Uncompromising speed and detail: Machin operates with a high velocity tempo, routinely scrolling through the digital storefront, messaging category leads, and insisting that bad news travel faster through the ranks than favorable metrics.
In shaping these as founder takeaways, it looks something like this:
1. Protect the magic, modernise the rest: Every startup possesses a core magic – a proprietary feature or an iconic product. Machin’s mandate at M&S was simple: preserve product quality and brand trust while overhauling legacy systems, distribution functions and digital interfaces.
Startup application: When pivoting or scaling, identify your core value proposition that customers identify you with. Modernise infrastructure, onboarding flows, and internal workflows, but never compromise the primary moat that gives you sustainable product-market fit.
2. Success means we keep going: Machin intentionally pushes the culture towards acknowledging wins, but remaining relentlessly focused on friction points and flaws. Continuous improvement dives alignment of ambition across the organisation..
Startup application: Early momentum can breed complacency. Lead your team to evaluate product launches by examining drop-off metrics and feature failures before celebrating high-level sign-ups. Never resting on your laurels is an infectious message for a startup team from the founder.
3. No compromise on customer proximity:Under Machin’s leadership, M&S instituted mandatory store shifts for corporate staff, requiring them to work on the retail floor each year and implement at least one tangible improvement based on that experience.
Startup application: Eliminate functional insulation by requiring engineers and product managers to handle customer support tickets or observe user research sessions regularly.
4. Prioritise speed over perfection: Machin stresses that speed of execution trumps lengthy analytical deliberation. Making a prompt decision using intuition, data, and quick feedback loops allows an organisation to adapt far faster than waiting for perfect data.
Startup application: Avoid analysis paralysis in early-stage product design. Ship MVP iterations rapidly, gather feedback from live users, and adjust based on their input.
5. Accelerate bad news: Machin actively encourages managers to deliver bad news before good news. This culture ensures operational bottlenecks, product quality or store display issues reach decision makers before they escalate into customer stumbles. Always be on the pulse is Machin’s mantra.
Startup application: Structure weekly updates around red flags, blockers, and declining metrics rather than polished achievements – but recognise and celebrate successes. Staying alert to in the moment issues is key to winning customers for a startup.
6. Build direct upward communication channels. Through initiatives like Straight to Stuart, Machin gathered frontline ideas directly from staff, bypassing intermediate management layers to implement practical changes rapidly across the chain.
Startup application: As your team grows, functional leads can inadvertently filter out critical ground-level insights. Create open, asynchronous feedback channels where junior folks can submit operational improvements directly to founders.
7. Lead with Company First, Colleagues Second, Self Last: Machin emphasises a clear priority of alignment: the enterprise mission comes first, the collective workforce second, and individual ego last.
Startup application: Feature debates and strategic pivots require setting aside founder vanity. Align every organisational decision around long-term company goals and value creation.
8. Treat growth as a permanent state. Machin rejects the idea that growth has a clear phase or achievement milestone, viewing growth as continuous adaptation and an ongoing requirement in the business as usual cycle.
Startup application: Scaling is not a linear journey with a fixed destination. Markets demand constant adaptation across product lines, business models, and GTM strategies.
9. Learn from competitors without hubris. Instead of dismissing rival offerings, Machin spends time studying competitor product offerings, results, supply chains, and marketing strategies to identify best practices and learning,
Startup application: Benchmark your competitors dispassionately. Analyse why users choose rival products, extract the underlying commercial learnings, and integrate those insights into your own roadmap
10. Demand Sleeves Rolled Up managers. Machin prioritises hiring managers who blend broad strategic vision with granular operational execution.
Startup application: Avoid hiring managers who only delegate. Early growth startups require hands-on, can-do leaders who can set high-level strategy while diving directly into daily operations, code reviews, or sales calls.
Summary: By combining operational rigour and customer relationship intimacy as advocated by Machin, founders can translate this ideology to build execution-focused agile ventures capable of long-term growth.
Founders spend energy optimising workflows, project plans, and now, AI tools. Yet the key driver of startup success is the team. Teamwork and collaboration ultimately runs on something more profound: leadership guiding the human operating system.
Machin’s leadership is rooted in having the same mindset across the organisation. His focus is on recognising customer touchpoints, building connections and trust with his colleagues. His leadership style could be termed conversational stewardship. Most leadership advice focuses on what leaders should say. I think an equally important question is how leaders shape the conversation itself, internally and externally.
