Tight Saju
- AI Fortune-Telling Comics
- $740,000 monthly revenue
Tight Saju is a Korean website that turns your fortune into a comic.
You enter your birth date and time, AI does a saju reading (Korea’s version of a birth chart), and a cartoon character walks you through it as you scroll.
The company behind it went from around $10K a month in 2024 to roughly $740K a month in 2025 
Most readings cost $15 to $50 each, and they’re mainly about love, exes and money.
There’s also a $2 compatibility check between you and your favourite celebrity.
It already has Japanese and Taiwanese versions, but no English one.
A recent report spotted the same gap 
Ship English saju readings as webtoons, for the audience that already watches Korean drama.
I found a handful of small English saju sites, but none doing the comic format.
So the format is proven, it just hasn’t been translated yet.
Pick a reading people already pay for in one language (saju, tarot, coffee grounds), and build it for another language market 
Make it a website rather than an app, since Apple now turns away new fortune-telling apps that aren’t meaningfully different.
