Quick answer
HireVue is the broader enterprise suite.
Spark Hire is clearer for lean async video screening.
Intrvio should enter the shortlist when live voice AI follow-up is the missing capability.
The category difference
HireVue and Spark Hire both sit in video interviewing, but they do not serve the same buying motion. HireVue leans toward larger assessment programs; Spark Hire markets a faster one-way video screen for lean teams.
If the team is debating candidate experience, completion rate, and whether one-way video is enough, add a voice AI workflow to the evaluation rather than comparing only video tools.
Where Intrvio fits in the decision
Intrvio is not a video interview suite. It is the GAIA voice interviewer for structured first-round screens.
Use it as the voice-first benchmark: can a live AI conversation produce better evidence than an async video answer for the roles you hire?
