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.
David Heinemeier Hansson (DHH) is a Danish programmer, entrepreneur, and racing driver best known for creating Ruby on Rails - the open-source web framework that powered GitHub, Shopify, Airbnb, and thousands of other companies. As CTO and co-owner of 37signals (makers of Basecamp and HEY email), he is one of tech's most outspoken critics of venture capital culture, cloud computing excess, and hustle-culture mythology. A 12-time Le Mans competitor with a class championship in 2014, DHH is also a bestselling author (REWORK, Remote) and a prolific open-source contributor whose side projects routinely reshape developer culture.
