ABOUT  US

FOUNDER'S  LETTER

I’ve been an entrepreneur since 1982 — born to build, explore, and learn. Curiosity and a drive to tackle things I’ve never tried before have always defined me. Along the way, I’ve faced challenges, celebrated successes, and embraced the freedom that comes with entrepreneurship.

One thing I’ve learned about myself is that I’m not an investor in the traditional sense. We don’t invest in other people’s ideas and dreams — we build them ourselves. I’m an entrepreneur at heart, and that passion has propelled me into solving wild problems that others couldn’t—or wouldn’t—tackle.

MAD HOUSE is the culmination of my knowledge, drive, and visionary mindset. It’s a place where I’ve brought together a rare breed of talented, battle-ready, and like-minded individuals. Together, we stand shoulder to shoulder, working on the most challenging ventures and creating the strongest brands in their industries. We transform visionary ideas into scalable startups, built on rock-solid foundations.

At MAD HOUSE, we demand change. We see it as our responsibility to create better products and services for people. If you’re a founder-minded, self-driven, and ambitious person, there might be space for you here. Over time, I hope more people will join MAD HOUSE to drive impactful change, rooted in strong values.

If you’re an investor looking to take part in our journey—whether by supporting one of our companies or the entire portfolio — we’re open to exploring how additional capital can scale our visions even further.

Yours,
