Launch your product on X

Launch day handled, from the video to the replies.

Then a read-out of who signed up and stayed.

Download RiverHow to start

How it works.

River makes your launch post with a short captioned video of the real product, writes a note to each supporter, posts at your chosen time, answers replies and quotes, and reports who signed up.

  1. Choose the launch and its link

    River suggests what, when and where the link goes, from your product, changelog and site.

  2. River builds the launch

    A 30 to 45 second captioned video, the post, a LinkedIn version and a note for every supporter.

  3. Launch day, covered

    Every reply and quote answered within minutes; anything new, like a price, goes to you first.

What you get.

  • A launch post with a captioned video of your real product, plus a LinkedIn version
  • A Launch Sheet of supporters, each with a short personal note
  • A next-day read-out of signups, activations and paying users by source

    Press + in your Dock, open Playbooks, and press Start. River suggests what’s launching and when, and who should hear first.

A few things to know.

Does River test the signup before launch?

Yes, at computer and phone size: a short description, a way to reach you, one clear next step and a signup page that loads. River never submits the signup itself.

How do I know the X launch worked?

The next day River counts signups, activations and paying users from Stripe and your product’s admin, names the people who stayed and offers to write to each.

What does it cost?

It uses your plan’s AI credit, like everything else in River. Supporters’ notes go from your own Gmail and X, not a mailing service.
