Hi! My name is Carl, and I'm a software engineer and entrepreneur. I have over 10 years of experience in software engineering, entrepreneurship, and investing across venture-backed startups, scale-ups, public companies, and venture funds. I founded Excel to pursue ideas I’m personally excited about while helping companies in my orbit. We are active builders. Excel is part advisory and consultancy and part holding company.

I started my career at Coinbase, where I fast-tracked advanced to Senior Software Engineer. During my time there, I wore many hats, working in commerce, decentralized exchange, centralized exchange, and core financial infrastructure. I’ve written code that has moved trillions of dollars (yes, with a T), secured hundreds of billions of dollars, and served hundreds of millions of users. In addition, I was the sole technical member of the Coinbase Ventures investment committee, where I managed the dev tools and protocol investment areas, making approximately 40 early-stage cryptocurrency investments and contributing to hundreds more.

After Coinbase, I started my own company as a technical CEO. I raised $5.3M from investors including Kindred Ventures, Matchstick, Foundry Group, Coinbase Ventures, and Chapter One. I led a team of 10, overseeing both engineering and go-to-market strategies. I have taken many products to market—ranging from simple SaaS applications to complex data infrastructure solutions. I consider myself a deeply technical generalist who understands both the business and the technical steps required to achieve company goals. My most recent venture before founding Excel was a YC-backed AI company, where I served as CTO. I also actively invest through my angel fund, 33x.fund, and currently hold stakes in approximately 30 early-stage tech startups.

Excel combines everything I've learned about building companies into a single entity. It allows me to build software, solve hard problems, and collaborate with other talented entrepreneurs. I also write actively on my blog, which you can check out above.
