We're a small team
giving meaning to the
world through data.
We started in June 2025 at the University of Seoul Campus Town. We're growing alongside clients across many industries and three products of our own.
Why
DataSketchers
We bring scattered documents, unused data, and repetitive decisions back to life. AI is the tool, data is the material, and design is how we make it usable for people.
Building a website used to take two to four weeks on average. Outsourcing started at 3 million KRW, and every revision was another cost. So we started differently — what you write in Notion becomes a website instantly, and what you discuss in a meeting becomes a mind map.
We make tools. But more precisely, we build the means for individuals to own their own brand. We accelerate the shift in industry's center of gravity, from companies to individuals.
How we work
Field interviews first
We start from how users actually behave, not from a feature list. The first two to five days are spent listening.
A minimal PoC
A small PoC instead of a big contract. Within two weeks we build something that works and validate it together.
Together through operations
It doesn't end at delivery. Like our annual SM contract with SK AX, we also operate the systems we build.
