Features of our platform

investment portfolio

Flexible, Personalized Portfolios

Smart investing isn’t one size fits all, so we allow end investors to build a personalized portfolio based on their own goals, beliefs, and interests. After investors are guided through a few simple questions, our algorithms gauge their timing and risk tolerance to create an appropriate portfolio. Individual portfolios are then built and presented using our curated selection of exchange-traded funds, your own institution’s models, or models offered by our partners including BlackRock.
