Smallcase is an investment platform in India that offers low-cost, innovative, and diversified investment options managed by SEBI-registered professionals. It is different from traditional Robo-advisors, as it does not use a questionnaire to determine risk tolerance and investment strategies. Instead, Smallcase allows investors to choose from a wide range of smallcases with different themes and investment styles, while also allowing users to create their own customized smallcases. Additionally, Smallcase requires an account with a broker, and the funds remain invested in the broker's account, while Smallcase provides the strategy, rebalancing, and investment picks.
