The Genius of Dynamic Pricing in B2C Apps

Kyzo created a simple B2C app that analyzes your Twitter (X) personality.

The app was built on top of Wordware as an example app to showcase how Wordware works.

It quickly gained popularity in Japan after a popular Japanese user shared it with their followers. It got 2.2m views.

The app also includes funny “roasts” based on users’ tweets, which helped it spread even faster.

And the roasts are hilarious too.

The app’s success seems natural, as many people enjoy this kind of content so the demand is there.

A good example is the subreddit /r/RoastMe with over 5.3 million members.

Just 2 weeks ago, the app was only a demo. Now, it's a viral money making machine.

The biggest lever seems to be localization. Many B2C AI tools are heavily focused on Western markets, but this app shows the potential in non-Western regions.

At its peak, the app made $4,000 USD per hour.

Dynamic Pricing Model

Kyzo used a clever pricing strategy. They adjust prices based on demand. When the app grows too fast, they turn on the paywall to slow it down. Then, they lower prices to boost virality again.

In Japan, users didn’t seem to mind the paywall. Many started paying for the app, which led to high revenue numbers, like $4,000 per hour. The revenue dropped only because of the time difference — Japan was asleep.

Their dynamic pricing approach is based on traffic:

  • When traffic is high, prices go up.

  • When traffic slows down, they lower prices.

The app also charges higher prices in wealthier countries, while other regions are set to $1.

They don’t fully automate the pricing, as many factors can affect it, like traffic spikes, scrapers, and technical issues. Full automation would require decent financial runaway or funding, which is why it’s only partially automated.

Due to the high cost of the X API, the team uses Apify to fetch user tweets. This allows them to keep costs down while still providing the core functionality of the app.

When the app went viral, it attracted over 5 million users and made $22,000 in just 8 hours.

X Personality Total Revenue

Even now, the app continues to grow organically, as you can see by searching for "wordware" on X.

The app likely passed $100,000 in revenue, and the founder stopped discussing it publicly—perhaps because it prints money.

People love taking personality tests. For some reason, even very smart people find them irresistible. One of my smartest friends keeps telling me to take the popular Myers–Briggs Type Indicator test.

Many enjoy sharing their results with friends, making these apps highly shareable.
