Pros & Cons

Brex

  • AI-native spend management reduces manual expense and policy enforcement work
  • Real-time spend alerts and automated controls catch issues before they become problems
  • Strong track record specifically serving startups and growth-stage companies
  • Now owned by Capital One as of April 2026, which could affect future product direction
  • Best suited to companies at a scale that benefits from dedicated spend management infrastructure
  • Worth watching how the acquisition affects independence and roadmap over time

Gemini

  • Deeply integrated across Google’s broader ecosystem (Search, Workspace, Android)
  • Ultra tier pricing was reduced from its original $250/month, improving accessibility
  • API pricing offers genuinely low-cost options (Flash-Lite at $0.10/million tokens) for cost-sensitive applications
  • Full Workspace integration requires at least Business Standard ($14/user/month), not available on cheaper Workspace tiers
  • Credit-based system layered on top of tier usage limits adds complexity to understanding real usage capacity
  • Ultra tier’s $99.99-$199.99/month range represents significant cost for maximum usage limits and Deep Think access
