Where they pull apart

Curious Thing

Stands out: Structured voice conversations at scale with a candidate-experience pitch, not a cheap SMS blaster.

Watch out: The vendor does not publish a pricing grid. Do not confuse it with the separate Lucy call-answering product sold at $24/mo.

Not the right fit for

  • SMBs hunting a $24/mo voice bot
  • Teams that will not use AI interviews
  • Buyers who need a public price

Tenzo AI

Stands out: Morgan, a screening agent that hits every applicant by phone/SMS/WhatsApp and writes a scored shortlist back, with 57-plus ATS names including Bullhorn, Workday, iCIMS, SAP SuccessFactors, and Greenhouse.

Watch out: Quote-only enterprise motion. A two-recruiter shop will be over-served.

Not the right fit for

  • SMBs that need a public seat price
  • Executive search
  • Teams that refuse AI voice screens

Pros and cons

Curious Thing

  • Structured voice first-rounds rather than trivia tests
  • Public API
  • Aimed at scale, not a single-recruiter gadget
  • Quote-only
  • No published price grid or connector list
  • Easy to confuse with unrelated 'Curious Thing' call-answering SKUs

Tenzo AI

  • Phone plus SMS plus WhatsApp, not video-only
  • Long ATS list including Bullhorn, Workday, and Greenhouse
  • Scores every applicant, not a sample
  • Quote-only
  • No public per-seat price
  • Overkill for low-volume professional hiring
