About ssunm

ssunm, 써냄

Our Korean name, 써냄, comes from a word meaning “to write something out.” It reflects the wish to take an idea through to a finished thing that someone can use.

Beginning with everyday life

Wanting to look back on the runs you have already recorded. Remembering dates that matter to you. Working out a number you are curious about. These everyday needs are where our products begin.

We notice a small inconvenience, use what we build, and keep improving it. We want each product to have a clear reason to exist.

What we have made

RunStory helps you return to your running days. Milestone keeps meaningful dates close. FinanceLab lets you explore numbers by changing the assumptions.
