Property and casualty-focused insurers Starr and Liberty Mutual completed a $100m investment in NYDIG, a provider of technology and investment solutions for Bitcoin. "We’ve been broadly and successfully investing with Ross and the Stone Ridge team across their various initiatives for years, including as a founding NYDIG investor in 2017. We are excited to continue our tradition of co-investment with them. We’ve also worked closely with Mike Sapnar for more than 25 years and congratulate Mike and NYDIG on his joining, and further propelling, the Stone Ridge ecosystem," Hank Greenberg, Starr Chairman and CEO.
