About SSTACK

SSTACK is a bootstrapped startup from Seoul, Korea. It is operated by 파이치치 (Paichichi), a Korean sole proprietorship registered on November 25, 2025 and run by founder SeungWon Lee (이승원).

We started as publishers. Running our own Naver blogs and a WordPress site taught us where AI helps and where it fails: models write fluently, but without research, structure and review they produce generic or wrong content. SSTACK is the workflow we built to fix that for ourselves, and we are now turning it into a product for other independent Korean publishers.
