Polyphon vs. User Interviews: recruiting was never the whole job

User Interviews does exactly what the name says: it finds people for your studies. A panel of millions, screeners, incentive handling, scheduling links — the recruiting logistics are genuinely solved. There's just a quiet assumption underneath: that once a participant lands on your calendar, you have the hours to run the session, and the hours after it to figure out what it meant. Recruiting was never the whole job. It was the first third of it.

What User Interviews actually is

Two products. Recruit sources participants from their external panel — strong when you need people who match a profile you can't reach. Research Hub manages recruiting from your own user base: opt-in forms, screeners, incentives, scheduling. Both are logistics layers, and good ones; G2 reviewers consistently praise the recruiting speed. The deck math most teams eventually do, though, is on what happens after the booking confirmation email.

The Logistics Treadmill

Take a modest goal: ten interviews a month. With recruiting fully solved, your team still owes — per session — an hour of moderation, plus prep, plus notes. Then synthesis across sessions, which practitioners consistently put at 4–8 hours per batch of ten. Call it 15–20 team hours a month, every month, before a single insight reaches a sprint. That's the treadmill: the better your recruiting tool works, the more sessions land on your calendar, and the more of your week disappears into running them. The 63% of teams who tell Maze's researchers that *time and bandwidth* block their research aren't failing to recruit. They're failing to keep up.

The math

And that's the version where everyone shows up. Industry no-show rates for scheduled remote sessions hover around 10–30%; every miss is a calendar slot you don't get back. Polyphon's model has no slot to miss — the interview starts the moment the user clicks, whether that's 2pm or 2am.

Where User Interviews is the right call

• You need external participants with a niche profile — procurement leads, ICU nurses, SREs at banks — that your own user base can't supply.
• Your methodology requires a human moderator — generative sessions with stimulus, co-design workshops.
• You have research staff whose time the sessions are budgeted against.

Where Polyphon is different

Polyphon assumes your most valuable participants are already in your database, and that nobody on your team has 20 spare hours. Connect Mixpanel or PostHog, define the cohort, state the goal. Polyphon writes the outreach and the interview script (you approve both), sends from your own mailbox with automatic nudges, and runs 15-minute AI voice conversations that probe and follow up like a trained interviewer. Synthesis, quotes, tickets, and the morning Slack digest are part of the same motion — not a second job waiting for you after the calls.
