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

Ribbon

Stands out: A public interview-capacity grid ($499 / $999 / $1,999) plus Ashby, Greenhouse, Lever, Bullhorn, Workday, and Workable named.

Watch out: Growth is 100 interviews/mo with $4 overage. This is not a $49 toy. Overage will dominate a busy week.

Not the right fit for

  • SMBs that need a $49 interviewer
  • Teams that will not use AI voice
  • Executive search

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

Ribbon

  • Public $499 Growth with a 7-day trial
  • Named ATS list including Greenhouse, Ashby, and Workday
  • Capacity plus overage instead of a pure quote
  • $4/interview overage on Growth
  • Wrong size for a two-recruiter shop
  • Not a human interviewer marketplace
