the software is the "easy" part. the hard part is gathering & aggregating vast amounts of public and propietary data, making it digestible, serving it with ultra low latency and earning the industry's trust: that can't be vibed must be earned. they've been doing it for decades. a frontend to display and analyze that data is the easy part. aside from the data moat, the top analysts in wall street use it because everyone else is using it (network effect).
