Who should pick which

  • Talent Acquisition Lead at a growing company (150 employees)

  • Enterprise Recruiting Operations Manager
    Pick: Gem

    Gem integrates with existing ATS like Workday or Greenhouse as an AI-powered CRM, offering advanced analytics and talent rediscovery without replacing the entire stack.

  • Independent Developer using Claude Code daily
    Pick: Caveman

    Caveman cuts 65-75% of output tokens, making AI responses faster and cheaper. It's free and easy to install, with support for multiple agents.
