I’m working on a portfolio & wealth data platform: https://github.com/finmars-platform/finmars-core

It helps to consolidate data from multiple sources, "slice & dice" data instantly from big picture overviews to smaller details like having a split screen. Basically extremely customisable tool.

On top of that, there's a marketplace where developers can build and monetise add-ons.
