Ben Ho is the Singapore-based founder of Hex (hex.sg), a web design and development studio, and the creator of Sendy - a widely-used self-hosted email newsletter application powered by Amazon SES. A self-taught designer and programmer, Ben co-founded Hex with Melly Fong in 2007, building websites and web applications for major brands like Sony, Nokia, Levi's, Changi Airport, and Tiger Beer. His best-known product, Sendy, launched in August 2012 and transformed the email marketing economics for thousands of businesses by offering a one-time $69 fee to send newsletters at a fraction of the cost of platforms like Campaign Monitor - roughly $1 versus $150 per 10,000 emails via Amazon SES.
Joe Gebbia co-founded Airbnb in 2008 out of a San Francisco living room - air mattresses, breakfast included - and turned a half-crazy idea into an $85B company. His current venture, Samara, builds factory-assembled, solar-ready backyard homes (ADUs) that go from permit to move-in in under seven months. In early 2025 he became America's first Chief Design Officer, tasked with redesigning the federal government's 27,000 websites. A Rhode Island School of Design graduate with dual majors in graphic and industrial design, Gebbia approaches every problem - housing affordability, government UX, refugee shelter - through the lens of democratic, empathetic design.
Raphael Schaad is a Swiss designer-engineer and Visiting Partner at Y Combinator who built three generation-defining products: iA Writer (the minimalist writing app), Flipboard (the original social magazine), and Cron (acquired by Notion in 2022).

Brian Chesky is the co-founder and CEO of Airbnb, the global home-sharing and travel marketplace operating in 220+ countries. A Rhode Island School of Design-trained industrial designer, Chesky built Airbnb from a $80/night air mattress rental in his San Francisco apartment into a company that went public in December 2020 at an ~$86.5 billion market cap — just nine months after losing 80% of its business to COVID-19. In 2024, his hands-on leadership philosophy sparked a viral debate in Silicon Valley under the term 'founder mode,' coined by Y Combinator's Paul Graham after a Chesky talk. As of 2025, he is steering Airbnb's boldest pivot yet: from a home-rental platform to a full-service travel ecosystem.
