Case Overview & Background

Josh Mohrer is not a developer, but Mixergy describes how he vibe coded Wave AI into a $7 million a year note-taking company. The app records what you say in meetings, on calls or straight into your phone, then transcribes and summarizes it. He says that over about three years a few people helped with higher-end engineering and marketing, but he has done most of the engineering and all of the support himself.

How AI Is Used

AI is the product: it transcribes and summarizes recordings. To build it he calls Cursor his home base for the app and web app code, and he has recently started using Claude Code to write features and documentation.

Step-by-Step Process

Step 01Enter early with a clear use case

He says there were few AI note-taking apps in the App Store when he launched.

Step 02Build with AI coding tools

He works in Cursor across the app and web app repos and has added Claude Code.

Step 03Buy installs with search ads

He uses Apple Search Ads for iOS and Google Ads for Android, at about 800 to 1,000 installs a day.

Step 04Add free SEO side projects

He built small free tools whose saved summaries bring a couple thousand search visits a day.

Customer Acquisition & Distribution

Apple Search Ads and Google Ads, App Store search helped by a 4.9 star rating with about 11,000 reviews, and free SEO side tools. He says Meta ads have not worked for him in more than a year.

Limitations, Risks & Failure Modes

What may not apply to you, and what could go wrong:

  • The figure is self-reported and was not independently checked
  • He says revenue has been flat for a few months
  • AI note-taking is now crowded, including large companies
  • Paid ads are a main channel, so acquisition costs matter

Key Takeaways

  • A non-developer can build and run a large app with AI coding tools
  • App Store ratings and search ads can drive steady installs
  • Small free tools can add search traffic at almost no cost
