Lenny Rachitsky is the author of Lenny's Newsletter, the world's largest product-focused newsletter with 1.2M+ subscribers, host of a top-10 global tech podcast, angel investor in 130+ companies, and former product lead at Airbnb where he helped transform instant booking from 5% to 80%+ of all reservations. Born in Odesa, Ukraine to refusenik parents who emigrated to the US when he was six, Lenny built a lean, high-quality media empire that earns $3M+ annually — all from a home studio in Marin County, with a digital fireplace backdrop and a strict no-meetings-before-3pm rule.
Jack Naglieri is the founder and CEO of Panther, a cloud-native SIEM platform that achieved unicorn status in 2021 with a $1.4B valuation. A former security engineer at Yahoo and Airbnb, he open-sourced StreamAlert in 2017 and parlayed that practitioner frustration into a $140M-funded company serving enterprises like Coinbase and Docker. He also writes Detection at Scale, a widely read Substack newsletter covering AI's transformation of security operations.
Lorin Hochstein is a Staff Software Engineer specializing in reliability at Airbnb, and one of the most respected voices in incident analysis and resilience engineering. Known for rewriting Chaos Monkey at Netflix, co-authoring the O'Reilly book 'Ansible: Up and Running', and contributing to the 'Learning from Incidents' community, he bridges the gap between academic complexity theory and real-world software operations. His blog 'Surfing Complexity' and conference talks challenge engineers to think more deeply about why systems fail and how humans make sense of them.
Karri Saarinen is the co-founder and CEO of Linear — a $1.25B unicorn project management tool trusted by 66% of Forbes' top 50 AI companies, including OpenAI, Ramp, and Vercel. A Finnish designer-turned-engineer who grew up questioning why everyday objects look ugly, attended 5,000-person LAN parties as a child, and turned that instinct into one of the most respected product careers in Silicon Valley. After shaping the visual language at Coinbase and Airbnb (Cereal typeface, Design Language System, Lottie, Google Material Design Award), he co-founded Linear in 2019 with two fellow Finns from Helsinki — and built it to 20,000+ customers and $100M+ ARR while staying profitable the entire time. His philosophy: quality is the growth strategy, tools embed opinions so choose accordingly, and the best MVP in a crowded category isn't minimal — it's sharply opinionated for a specific audience.
