Bloom, a zero-commission stock investing tool for teenage investors, reached 1 million downloads after launching in February 2022. The startup founded by Allan Maman and Sam Yang provides a brokerage account and teaches those aged 13 and older how to build wealth through interactive lessons on investing, stocks and finance. If Maman’s name looks familiar, that’s because he is credited with making a better version of the fidget spinner that helped the devices go viral.
