Where each one falls short

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

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

Pi

  • Inflection AI's own homepage (2024 archive) pivoted its headline positioning to enterprise AI licensing rather than the consumer Pi assistant, with no consumer pricing or plans published on the corporate site
  • Requires iOS 16 or later, per the App Store listing
