## FAQ

### Which companies buy speech data?

Speech recognition, text-to-speech, voice agent and dubbing companies, plus model labs adding voice. Revnu ranks them by funding and by job posts for speech data, linguists and audio data operations.

### How do I start finding Speech data buyers with Revnu?

Sign up at revnu.com/sign-up, give Revnu your website and tell it you sell to these companies. It builds the list, finds the right person at each and drafts the first email for you to approve. revnu.com/docs/find-leads explains how it finds and checks each company, and revnu.com/docs/get-started covers your first day.

### How many companies like this can Revnu find?

409 US speech recognition and voice AI companies with 10 to 1,000 people matched this search on November 8, 2026. Revnu narrows them to the ones that fit who buys from you, and ranks them by a reason to reach out now.

### Are the companies in the demo real?

Yes. The companies, counts, funding and headquarters are a dated snapshot of the data Revnu searches: company, funding, job-post and people data from third-party providers, plus the public web. The people and companies in the buyers example are made up, because we don't publish real people's contact details.

### Does Revnu send anything without me?

Only what you allow. Three steps, in order. First, your first sequence waits for you to read and approve it. Then Settings > Agent > What Needs Your Approval decides: on Pro, a new sequence starts on its own and its steps send without asking each time, while one-off emails, LinkedIn invites and LinkedIn messages ask first. Switch any of them either way. And whatever you set, replies to prospects, spend, budgets, booking links and new inboxes always wait for your yes.

### How fast does it start?

Revnu prepares its first piece of work, such as a list of buyers or a blog draft, within minutes of starting. Email from your own Gmail or Outlook can go out the same day; new sending inboxes Revnu buys warm up first, which takes days to weeks.

### What does it cost?

Pro is from $99 a month, with no minimum term, and you can cancel from billing settings. Sending domains, inboxes and lead data are included. Ad spend is billed by the ad platforms to your own accounts. If you want Revnu's team to run it with you, Managed is priced on a call.
