The app, which charges $1 per month for accounts under $5,000, also offers the option to set automatic investments to help users grow their "stash" over time. It charges a 0.25 percent annual fee for accounts over $5,000. Stash is among a growing cohort of tech-savvy investment managers taking advantage of automation and digital technologies to service consumers usually overlooked by the mainstream wealth management industry. Stash services 850,000 accounts, having added over half a million investors on its platform since the start of the year alone. Around 86 percent of its users are first-time investors, it said.
