Nvstr
Nvstr (pronounced "Investor") is a modern investing platform designed by ex-hedge fund guys to make smart investing simple. Today's online and app-based brokerages are still patterned after pioneers from the 1990s. Nvstr is different. It empowers you to invest better with the collective experience of people you trust and the community. Nvstr's technology also helps you optimally diversify your portfolio in a click. It's based on independent Nobel Prize winning research - it's the world's first brokerage with this technology. Right now they're giving people up to $500 free cash to invest when you join (selected at random, but you're guaranteed at least $10).
