User interviews on autopilot.
Research while you ship.
Polyphon ingests your users, conducts email outreach, runs AI voice interviews, opens tickets in Linear and Jira, and posts insight to Slack daily; all autonomously. You focus on shipping; we handle the research.
Built by the best
You know you should talk to users.
The process makes it impossible.
Three bottlenecks show up on every team, before good questions ever get good answers.
You burn cycles just getting people to show up
Lists live in spreadsheets. Outreach is manual. Most users never make it to a conversation, and the sprint already moved on.
Depth doesn't scale with how fast you ship
A few great interviews beat a survey, but moderator time, scheduling, and context caps how many you can run before the next release.
The insight rarely survives the handoff
Transcripts and decks pile up. By the time someone summarizes patterns, the team has already decided in Slack without the evidence.
From live cohorts to
daily signal in Slack
Four steps. Import who to talk to, get them on the line, capture truth in voice, and ship what you learn, without another dashboard to babysit.
Step 01
Ingest cohorts from the tools you already trust
Connect Mixpanel, Amplitude, or PostHog, or drop in a CSV. Polyphon syncs segments so you’re always recruiting from the cohort that matches the job (churn risk, power users, new signups), not a stale export you forgot to refresh.
Step 02
Outreach that runs while you stay out of the inbox
Polyphon emails the right people with consent-first messaging, nudges, and booking links. You set the research goal once; we handle the back-and-forth so interviews actually get scheduled, without you becoming a part-time SDR.
Step 03
AI moderator interviews that sound like a senior researcher
Our voice agent runs adaptive conversations: probing thin answers, following emotional cues, and keeping the discussion on-strategy. You get qualitative depth at a scale no human team could sustain for the same job.
Step 04
Insights, tickets, and Slack, where work already happens
As interviews complete, Polyphon synthesizes themes, opens issues in Linear or Jira, and posts full insight digests to Slack every day. The job shifts from “hunt for quotes in docs” to “prioritize what your team already sees in-channel.”
