500 Startups

500 Startups is a global venture capital seed fund and startup accelerator based in Silicon Valley with ~$200M in assets under management. Our team of 100+ people live in over 20 countries and speak over 20 languages, and we have invested in over 1,400 companies from more than 50 countries since our inception in 2010. In addition to making investments globally, we run accelerator programs in San Francisco and Silicon Valley four times per year emphasizing internet marketing and customer acquisition, design and user experience, and lean startup practices and metrics. Our investment team and mentor network has operational experience at companies such as PayPal, Google, Facebook, Amazon, YouTube, Microsoft, Yahoo, LinkedIn, eBay, Twitter and Apple.

Some of our portfolio companies include Credit Karma, Twilio, GrabTaxi, Ipsy, and Udemy. Our founders have had over 50 exits, including MakerBot (acquired by Stratasys for $400M), Wildfire Interactive (acquired by Google for $350M), and Viki (acquired by Rakuten for $200M). We have also invested in hundreds of other companies still working hard to make a dent in the universe, and many other hundreds that didn’t quite get there. Regardless they are all still #500STRONG, and still family.

Bring Silicon Valley To Japan

Along with our investment, we bring Silicon Valley best practices to the local ecosystem—simple concepts like Silicon Valley standard financing documents, to more complicated areas like solving founder dilemmas, fundraising, and getting to an exit.
