  1. From Corporate VP to Startup CEO — Egil Østhus on Leadership, Culture, and Letting Go of Ego

    From Corporate VP to Startup CEO — Egil Østhus on Leadership, Culture, and Letting Go of Ego

    This week, I’m joined by Egil Østhus — co-founder and CEO of Unleash, an open-source feature management platform used by teams at Wayfair, T-Mobile, Allianz, and more. Before launching Unleash, Egil led engineering at Visma, a 6,000+ developer SaaS giant. He’s seen both the slow grind of corporate transformation and the chaos of building from scratch — and in this conversation, we talk about what he’s learned from both. We get into: * Why leadership isn’t so different between big companies and startups * How they built a no-ego, high-trust culture at Unleash * Why being too frugal nearly slowed them down * Egil’s coaching-style approach to leading teams * How he handles remote work, loneliness, and vulnerability as a founder There’s a moment in this interview — where Egil shares how he felt completely exposed in front of his team — that really stayed with me. If you’ve ever felt the weight of leadership, you’ll hear yourself in this episode. Let me know what resonates with you — or forward it to someone building something brave. 🎧 Timestamps: * 0:00 Intro * 2:10 Why feature management matters * 7:40 What changes (and what doesn’t) when you go from corporate to startup * 12:00 Building culture from day one * 16:10 Leading with coaching, not command * 23:00 Vulnerability, trust, and showing up * 28:00 Remote work, loneliness, and presence * 33:00 What Egil’s still figuring out 📌 Subscribe for more interviews with scaleup leaders. 🔗 Learn more about Unleash: https://www.getunleash.io/ 📣 Follow Egil: https://www.linkedin.com/in/egilosthus/ This is a public episode.

  2. The Culture Shift After Series A

    The Culture Shift After Series A

    What do you do when you’re suddenly in charge… and totally unprepared? In this episode, I speak with Gillian Davis, leadership strategist and founder of Overtime Leader, who’s spent the last decade helping scaleups grow their leadership and culture as they move from scrappy startup to mature company. Gillian’s journey started with crisis: she took over her family’s business when her father fell ill. She later left corporate “with a vengeance,” and found herself dropped into a high-growth tech company with zero systems, zero onboarding, and a ton to figure out. Since then, she’s served as VP of People at WeTransfer, co-authored the book First-Time Leader with George Bradt, and worked with leadership teams to help them scale intentionally — before chaos sets in. In this conversation, we talk about: * The intern confrontation that reshaped her leadership style * Why she quit corporate without a plan — and what she found instead * How product thinking changed how she does organisational design * Common mistakes founders make when hiring senior leaders * Why fast growth doesn’t mean rushing leadership Whether you’re a founder, a first-time VP, or just someone trying to lead through uncertainty — this one’s packed with stories and insights you’ll want to remember. 🔗 Guest Links * Gillian’s website: OvertimeLeader.com * Gillian on LinkedIn: linkedin.com/in/davisgillian * Her book: First-Time Leader (with George Bradt) 🗂️ Timestamps * 00:00 – Intro & Gillian’s origin story * 05:30 – Leading through crisis with no playbook * 15:00 – The intern confrontation that changed everything * 22:00 – Leaving corporate with no plan * 26:00 – Joining a tech startup with no systems * 32:00 – Product thinking meets leadership * 45:00 – Helping founders build leadership post-Series A * 59:00 – The importance of brave, long-term leadership This is a public episode.

    S2E02: From Google to Leading Change

    We often think great leadership is about having all the answers and staying composed under pressure. But what if the real key to leading a high-performing team is being open about your mistakes? In this episode, Kim Wylie reflects on two decades of leadership experience at Google, Farfetch, and scale-ups—sharing what actually builds trust and performance when you’re stepping into a new team. We talk about: • Why trying to be the perfect manager backfires • How Kim built psychological safety in a team that didn’t trust her at first • How to handle resistance to new ways of working in distributed teams • The team rituals she uses to foster connection, even across regions • What to do when your team gives you negative feedback • The neuroscience of why solving everyone’s problems is not good leadership • And how even senior leaders still struggle with imposter syndrome This is a masterclass in human-centred leadership—with practical tools, real stories, and the kind of honest reflection most leaders wish they heard more often. 🧠 Some Takeaways “If you’re a manager and you’re always solving everyone’s problems, you’re robbing them of that dopamine hit.” “One of the biggest lessons I learned is that being vulnerable builds trust—and trust drives performance.” “People need to see that how you show up on day one is how you’re going to keep showing up.” 🔗 Links & Resources Follow Kim on LinkedIn Watch the full video interview on YouTube Subscribe to the podcast for more real stories and practical leadership insights.
