Best of luck to them, but this one is dead on arrival. Symphony already tried to create an alternative with the backing of a number of the major investment banks, and failed miserably. As another commenter pointed out, the integrations are a huge part of the value proposition and would take a massive effort to recreate, assuming the data providers even find it worthwhile to engage. Then you need to run a brokerage, a ticker factory and a large news desk just to come close to parity. Heck, even other large companies like Refinitiv have trouble competing.
