DB1 Ventures, the corporate venture capital arm of Deutsche Börse, led a funding round in OptimX Markets, a block trading platform. Financial terms were not disclosed. “Buy side firms in the EU have a continued preference for executing large cash equity transactions in blocks, which has been reinforced by MiFID II. OptimX has a compelling value proposition for this off-order book market. We look forward to working closely with the team and our co-investors to build and scale the business,” Eric Leupold, Deutsche Börse Managing Director of Cash Market.
