    No Investors, No Problem - how George Sullivan has grown his bootstrapped business, The Sole Supplier, to drive £50million GMV per year

    "If I had taken investment in the early years, it would've wrecked me. I wouldn't have been able to deal with investors breathing down my neck." George Sullivan turned his obsession with trainers into The Sole Supplier, a business driving £50 million GMV annually - without a single investor. His biggest insight? Bootstrapping isn't just about keeping control; it's about growing at a pace that matches your capacity as a founder. In today's episode, I'm joined by George Sullivan, founder and CEO of The Sole Supplier, Europe's leading sneaker marketplace. After discovering parkour at 13 and building various side hustles, George launched Sole Supplier at 22 and has grown it over 12 years to work with the world's biggest brands, building a team of 30 and generating billions in content views. His journey includes navigating untreated ADHD, rejecting the toxic hustle culture narrative, and proving that sustainable growth beats venture-backed chaos. Together we unpack: Why taking investment would have destroyed his business in the early yearsHow ADHD can be both a superpower and a liability in fast-growth environmentsThe danger of being bamboozled by credentials and investor pressure when you're youngWhy quality beats quantity and hustle culture is destructive for motivated foundersHow to validate spending decisions when bootstrapping with limited resources👆 If you're a founder questioning whether you need investment to scale, or struggling to balance ambition with sustainable growth, this conversation will completely reframe how you think about building a business on your own terms. About George Sullivan George Sullivan is the founder and CEO of Sole Supplier, a leading sneaker marketplace that has driven over £50 million in GMV annually.

    "Don't waste your chips on bad hands." Dimitar Stanimiroff has been through multiple exits, some successful, some painful shutdowns. He co-founded WePow(acquired) and Heresy (shut down after 3.5 years). His biggest financial return came from joining Stack Overflow, not founding his own company.

    The Secret to Enjoying Your Scale-Up Journey, with Nick Baker

    Why You Can't Sustain What You Don't Enjoy Nick Baker left his successful consultancy after 25 years, burnt out from always being "on." He became a non-exec, convinced he'd never return to operational leadership. Then UK Padel came along, and he became CEO because he genuinely loved what they were building. The lesson? You can endure anything temporarily, but you can't sustain what you don't enjoy. About Nick Baker: Nick is the CEO of UK Padel and former co-founder of Alpha FMC, which he took through private equity investment to a successful IPO. After spending 25 years in financial services and stepping back from executive roles, Nick found himself drawn back into operational leadership through his passion for racket sports and building something he truly believed in. Together we unpack: Why genuine passion for your business isn't just nice-to-have; it's essential for long-term successHow to know when it's time to step away and make yourself redundant the right wayThe secret to staying authentic as you scale (hint: stay involved in delivery)Why founder-led selling works so well and how to maintain that edge👆 If you're a founder feeling disconnected from your business or wondering how to sustain your energy for the long journey ahead, this conversation will give you clarity. About Nick Baker Nick Baker is the CEO of UK Padel, which operates multiple padel clubs across the UK and runs the country's biggest national tournaments.

    Shifting from Founder to CEO, with Jennifer Clamp

    The CEO who takes all the meeting notes isn't leading. They're sabotaging their own team.

    Rethinking B2B Marketing in 2025 with Employee Generated Content (EGC), with Katie Street

    Your best marketing content creators probably aren't who you think they are. Most founders assume it has to be them. They overlook the thought leaders already inside their team. They default to safe, scripted content that feels awkward and inauthentic. But what if the future of marketing wasn’t about personal branding at all… What if it was about empowering your entire team? In today’s episode, I’m joined by Katie Street, founder and MD of Street Agency and host of the chart-topping podcast Marketing in the Madness. Katie works with some of the world’s top marketing tech companies and believes we're at a turning point—where brands that don’t show up with real, human content will get left behind. In an AI-driven world, authenticity and trust are your unfair advantage. And if you’re not visible, someone louder (and less qualified) will be. Together we unpack: How to move beyond founder-led content to team-powered marketingWhy authentic, human content beats polished scripts every timeShifting from a scarcity mindset to one of empowerment when leading your teamThe rising importance of in-person events in an AI-driven world👆 If you're a founder or leader looking to scale your marketing authentically, connect with us below. About Katie Street Katie Street is the founder and MD of Street Agency, an award-winning sales and marketing expert with recognition from BD 100, The APHIS and Beamer.
