We build AI products that move people

Which words, at which moment, move a person? We are building a formula that predicts it with data and AI.

Petalab is an AI content company in Seoul, founded in July 2025. Every business comes down to winning people's hearts, so we study what moves them and build it into our products. We proved the method first with our own AI content services, and we are now taking it into the global AI companion market.

What we do

  • AI content services

    We build and run our own AI content services. Within a year of founding, the cumulative number of payments grew 2,862x.

  • Content and marketing

    We run our own marketing end to end: performance, content, brand and growth. We judge content by the revenue it brings in. Our most-watched ad has 11.4M views, and 16 of our ads have passed 500K.

  • Data and systems

    We design each service around purchase conversion, check decisions against the data, and build systems that let a small team keep growing revenue.

Track record

We started with three people and have stayed profitable since reaching break-even in September 2025.

Next: the global AI companion market

A team that knows what moves people has no reason to stay in one category. We are taking what we have learned into a global market worth about KRW 65 trillion.

How we work

  1. Keep a single priority

    There are always many important things. We pick the one that matters most, put everything into it and drop the rest.

  2. If it's bad, say it's bad

    We don't let things slide to keep the peace. Honest feedback is what leads to the best results.

  3. Criticism of the work is not criticism of the person

    We separate the work from the person, so nobody gets hurt and everyone can aim higher.

  4. What I make belongs to the team

    Wins and misses are shared, so we take responsibility together until the end.

  5. That's how we make our best work

    Every uncomfortable choice adds up and comes back as a better result.
