Honza Široký
Angel Investor
Prague, Czech Republic
Honza Široký is a pre-seed investor in Prague focused on Health Care and Space Travel. I started with web development at the age of 15, working on various commercial and school projects while exploring other areas of software engineering and computer science. I joined Mews as one of the first two developers set to build the product. Ten years later, as a CTO, I was leaving a growing team of 170 engineers and a series C company withUSD 100M+ ARR. Currently, I'm involved in CzechFounders VC as a limited partner and an investment committee member. Besides that, I'm taking my first steps as an angel investor, enjoy mentoring of early stage startups, and keep pursuing my lifelong passion for sports.
