The ICONS Show – Details, episodes & analysis

Oskar Hartmann is one of Europe's most prolific serial entrepreneurs and early-stage investors — a man who launched his first company on the day Lehman Brothers collapsed, co-founded over 20 companies while running a 1,500-person business, broke two world records in indoor rowing after a near-total physical breakdown, and then built a 17-city stand-up comedy tour just to get something out of his system. He's the founder of Accumulator, a SEC-regulated share-pooling fund designed to help unicorn founders diversify their wealth — now holding $500M in approved assets from 65 member companies including Monzo, Discord, and Etoro. In this conversation with host Roman, Oskar shares the unvarnished truth behind building in chaos: the €500K personal liability that triggered a decade of parallel company-building, the hospital stay that broke his nervous system, the philosophy of 'alternating' beast mode and recovery, and the concept of 'mini lives' — how he approaches each chapter of his personal life with the same focused intensity he brings to business.

Marc-Alexander Christ, co-founder at SumUp, pulls back the curtain on how a five-founder startup launched simultaneously in Dublin, Berlin, and Bulgaria in 2012 and grew into one of Europe's most formidable fintech companies — serving 4 million merchants across 36 countries at an approximately €8 billion valuation. From the early mistake of hiring 100 salespeople before achieving product-market fit, to the iron discipline of a 12-month payback period that governs every growth decision, to a planned proprietary stablecoin - Marc delivers a rare, unfiltered account of what it actually takes to build payments infrastructure at global scale for small merchants who were almost entirely underserved before SumUp existed.

• SumUp's unusual origin: 5 co-founders, 3 launch locations simultaneously — Dublin, Berlin, and Bulgaria
• The original merchant super-app vision and why early investors said it was too big to build
• Why payment is the single universal common denominator across every small merchant business type
• The €10/month per merchant revenue problem and why human field sales was a structural impossibility
• Facebook as the winning early acquisition channel — the discovery of a 9-month payback period that worked
• The 12-month payback period rule and the math behind why incremental CAC breaks responsible growth
• SumUp's three business lines: Get Paid (card acceptance), Run My Business (POS/software), SumUp Card Account (banking)
• Self-setup, zero human labor onboarding — marginal cost of adding a new merchant approaches zero
• Tap-on-phone: 30% of new merchant acquisition, SumUp as European market leader
• M&A strategy: 10+ acquisitions, lessons from Tiller (CRM fragmentation failure) vs. Payleven (48-hour integration success)
• The "run all distances" philosophy — competing horizontally across verticals rather than owning one like Toast
• SumUp Edge: AI co-pilot for small merchants with competitive pricing intelligence and seasonal recommendations
• Building a proprietary stablecoin to reduce payment settlement from 24-48 hours to instant
• Why acquiring AI companies makes no sense right now — but deploying AI everywhere internally does
• Consumer products: SumUp Pay (neobank card and account) and SumUp loyalty aggregator
• Marketing evolution: performance-first → retail (14,000 stores) → 3,400 integration partners → direct and field sales

In this episode of ICONS, host Roman Kirsch sits down with Tushar Ahluwalia, Co-Founder of Razor Group, to unpack one of the most complex entrepreneurial journeys in e-commerce. Tushar's career spans three continents and three ventures: building India's first major D2C fashion brand (SBL) that reached 100 crores in revenue, creating Razor Group into a $700 million revenue aggregator that acquired 300+ Amazon businesses, and now launching ADA AI to solve supply chain complexity with artificial intelligence. This conversation reveals the operational playbooks, capital strategy, and leadership principles behind building at massive scale—plus the hard-earned lessons from navigating board dynamics, capital stack challenges, and market timing.

• Navigating complex board relationships and investor dynamics as a first-time founder
• Timing market opportunities and surviving when assumptions change
• The FBA aggregator model: capital structure, underwriting assumptions, and what actually happened

In this episode of ICONS, host Roman Kirsch interviews Heini Zachariassen, founder of Vivino and current chairman of the board, who is now building Vota (vota.org), a quality rating system for restaurants. Growing up on the remote Faroe Islands (population 50,000) between Norway and Iceland, Heini developed the entrepreneurial belief that you can walk to parliament and knock on the prime minister's door to create change. This island mindset shaped his approach to building global businesses. Despite knowing nothing about wine, Heini transformed his intimidation at wine store "walls of wine" into the world's largest wine database with over 15 million wines and over 70 million users. Starting as a simple wine scanning app competing against 600 other wine apps, Vivino succeeded by focusing relentlessly on match rate over aesthetics, achieving 70-80% word-of-mouth growth with near-zero marketing spend and reaching a billion-dollar valuation during the 2021 boom. Through surviving the COVID boom-bust cycle and transitioning from community to marketplace, Heini shares hard-won lessons about founder-market fit, data moats, and building sustainable consumer businesses in competitive markets. Today, he remains connected to his Faroe Islands roots, regularly visiting home where they now boast a two-star Michelin restaurant while he builds a whiskey distillery to help diversify the local economy beyond fishing.

Her unique perspective comes from successfully navigating vastly different corporate cultures while maintaining brand consistency and driving exponential growth.

From their first $10,000 acquisition to writing $500 million checks, the founders share how they built a unique culture-driven approach to scaling tech businesses through strategic acquisitions, proprietary technology platforms, and an unconventional talent strategy focused entirely on developing young graduates into business leaders.

His journey reveals the power of product-first thinking, authentic community building, and leveraging network effects to scale from zero to millions of users. Through SoundCloud's transformation from a simple sharing tool to a cultural phenomenon that launched entire music genres, and Dance's approach to turning mobility hardware into a beloved subscription service, Eric demonstrates how great brands emerge from solving real user pain points with obsessive attention to product quality and customer feedback.

In this episode of ICONS, Roman Kirsch interviews Charlie Bowes-Lyon, Co-founder and CMO of Wild, the refillable deodorant brand recently acquired by Unilever. Starting with a mission to remove single-use plastic from the bathroom, Wild transformed a £5 million UK natural deodorant market into a global sustainable brand worth hundreds of millions. By rejecting the traditional "eco-aesthetic" and instead creating colorful, lifestyle-focused products, Wild made sustainability approachable for mainstream consumers. Their journey from launch during COVID lockdowns to a major Unilever acquisition demonstrates how purpose-driven products can achieve commercial success when product quality and brand experience take priority over sustainability messaging.
