    Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now.

    Hey all My name is Adam, and I’m a co-founder at Yotta (YC S20), an app that uses behavioral psychology to help people save money by making saving exciting.

For comparison, most high-yield savings accounts with FDIC coverage are paying ~2%. The backstory: I Bonds were established by the US Treasury in 1998 to…
