London-based startup Blockchain, a leading software platform for digital assets, announced last week that they have raised a Series B of $40 million with Lakestar and GV (formerly Google Ventures) with additional participation from Nokota Management and Digital Currency Group.

Their Series B represents the most substantial investment in the fintech space since Brexit and is the largest Series B raised by any digital currency company to date, the company stated. This brings their total capital raised to over $70 million.

Their existing investors – Lightspeed Venture Partners, Mosaic Ventures, Prudence Holdings, Virgin, and Sir Richard Branson (Virgin Group) – also participated in the round, the startup said.

According to Blockchain, “their mission is “to create an open, accessible, and fair financial future for billions across the globe, one piece of software at a time,” and this capital moves them “one step closer to delivering on that mission.”
