Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Acorns

  • A flat monthly subscription regardless of balance, so $3 a month on Bronze is a heavy percentage on a small account
  • The emergency savings account and the 1 percent IRA match need Silver at $6 a month
  • Custom portfolios, Acorns Early for children and Money Manager are Gold tier only at $12 a month
  • There is no free tier

Brex

  • The free Essentials tier is limited to two legal entities
  • Premium is $12 per user per month, so cost scales with headcount using the card
  • Enterprise and Smart Card pricing is not published
  • Eligibility criteria are not stated anywhere on the pricing page, which matters for a product that extends credit
