About Ctrl Alt

Ctrl Alt is designing and operating the on-chain infrastructure powering digital capital markets globally. We bring together a unique blend of expertise in financial markets and cutting-edge in-house technology to deliver tailored, compliant solutions in the alternative assets space. Since launching in 2022, we’ve tokenized over $1.7bn in assets across real estate, private credit, funds, litigation finance and more.

We’re building a high-performance, people-first culture where ambitious individuals can thrive. We move fast, think big and hold ourselves to a high bar, while keeping things collaborative, open and genuinely fun. At Ctrl Alt ideas win on merit, teams work closely with leadership, and everyone has a voice in shaping what we build next.

We believe that hard work should come with real reward. You won’t just join a company - you’ll help build one. Last year alone, we grew from 17 to 50 people, and this year we’re going faster and further. That means real responsibility, meaningful impact, and the opportunity to grow alongside a company that’s redefining the future of finance through the tokenization of alternative assets.

If you’re excited by scale-up energy, ownership, and the chance to help shape both a business and a culture, Ctrl Alt is where you can do the most rewarding work of your career.
