Tobias Lütke and the shop that sold its toolbox
He set out to sell snowboards. The software became Shopify. Two decades later, Tobias Lütke is still working on the same problem: how much easier can it be to start something of your own?
Johannes Dwi Cahyo Kristanto and the last 100 kilos

Chad Wilken Took the Windowless Room
He left Hudl for a windowless room behind a roofing company and spent nearly eleven years turning a messy photo problem into durable software. Then, with uncommon restraint, Chad Wilken stopped to decide what should come next.
Kamal Mahyuddin Kept Choosing the Work Before It Looked Important
Before workplace software became a category, a Malaysian Rubyist arrived at Envoy as its second engineering hire. The quiet thread through his career is a taste for useful infrastructure - the kind people notice only after it works.
Todd Kaufman Built a Software Company That Its Employees Could Own
A sixth-grade encounter with BASIC led to a career in code, a roadside Chili’s led to Test Double, and a stubborn question about fairness led its founders to give the company to its employees.
Josh Knowles
Josh Knowles is the CEO of Code Climate, the New York software company whose Velocity platform gives engineering leaders at large organizations data on how their teams actually build software. A Ruby developer by training with more than two decades in the field, he spent years at Pivotal Labs and VMware building and running consulting and application-services teams across the US and Europe before joining Code Climate, rising from VP of Strategy and Operations to General Manager to CEO. He took the top job as Code Climate spun out its code-quality product into a separate company, Qlty Software, and refocused entirely on software engineering intelligence for large, complex enterprises.

Before Avochato he co-founded Jobr, a Tinder-style job-search app acquired by Monster.com. A self-taught coder with a mechanical engineering background, he turned a side project into a product used by 1,000+ businesses for millions of two-way conversations.

Jonathan Perichon

A French-born software engineer who discovered the gig economy's broken background check infrastructure while working at an LA startup, Perichon turned that frustration into a $4.6 billion company serving over 100,000 clients including DoorDash, Lyft, Coinbase, and Uber. A Y Combinator S14 alumnus who applied three times before getting in, he embodies the principle that persistence and execution beat credentials every time.
Max Wang
Max Wang is the Co-Founder and CTO of Workstream, a San Francisco-based HR and payroll platform built specifically for America's hourly workforce. He co-founded China's AngelList equivalent (VC.CN) in 2011, built it to a 50-person team, then crossed the Pacific to co-build Workstream with Desmond Lim and Lei Xu after a 100-interview discovery sprint revealed that hiring hourly workers was a massive unsolved problem. Today, Workstream serves 4,000+ businesses across 24,000 locations, has raised $118 million, and is deploying AI tools - including VoiceAI - to compress hiring cycles from weeks to hours for restaurants, franchises, and deskless-workforce employers.
Jason Fried
Jason Fried is the co-founder and CEO of 37signals, the bootstrapped software company behind Basecamp, HEY, and ONCE. A contrarian voice in tech, he has spent 25+ years arguing that smaller is smarter, calm beats hustle, and profitable beats funded. He co-wrote Rework - a Wall Street Journal and New York Times bestseller - and his TED Talk on why work doesn't happen at work has millions of views. Along with co-founder David Heinemeier Hansson, he has built one of the most influential (and deliberately small) software companies in history.
Nate Kontny
Nate Kontny is a Chicago-based serial founder, engineer, and writer who went from chemical engineering at UIUC to co-founding two Y Combinator companies (Inkling W06, Cityposh S11), running Highrise as CEO for Jason Fried, writing prolifically across Medium, HuffPost, and Fast Company, and building a suite of solo products - most recently AlliHat, a Safari extension embedding Claude AI directly in the browser. Currently Staff Engineer at Fivetran (post-Census acquisition), he is known for his radical transparency about failure, his 250-words-a-day writing discipline, and a philosophy that shipping imperfect work beats endless polishing.
Tobi Lutke
Tobias 'Tobi' Lütke is the German-Canadian co-founder and CEO of Shopify, one of the world's largest e-commerce platforms. Born in 1980 in Koblenz, Germany, he received a computer at age six and left school after 10th grade to complete a programming apprenticeship, never attending university. After emigrating to Canada in 2003, he built an online snowboard shop called Snowdevil and — finding every existing e-commerce platform inadequate — coded his own solution in Ruby on Rails in two months. That solution became Shopify, which he launched as a standalone product in 2006. Shopify went public in 2015, and as of 2025 processes over $1.6 trillion in cumulative gross merchandise volume for millions of merchants across 175+ countries, commanding over 14% of the US e-commerce market. Lutke is known for his radical candor, his open-source roots, and his unusual interests for a tech CEO: competitive racing driver, avid skier, and serious gamer who credits strategy games with shaping his business thinking. His April 2025 internal memo mandating AI proficiency as a baseline expectation became one of the most widely-discussed corporate AI policy statements of the year.
David Heinemeier Hansson
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.
