# Marius Ciocirlan > Designed the first Groupon app. Co-Founder @ShareGrid (sold for 8 figures). Current Angel Investor. I’ve had the opportunity to be one of the first designers on the initial Groupon mobile app which was downloaded more than 100m times. I later started my own venture backed startup called ShareGrid. A two-sided rental marketplace for filmmakers and photographers. The site is home to over 200,000 creatives renting out over a billion dollars worth of equipment- making it the largest film/photo rental marketplaces in the world. We sold the business for over 8 figures. After the exit I became an angel investor and the Managing Director at Techstars Seattle where I got to invest in over 36 companies.
