Upstream

Upstream이란?

Most analysts learn SQL. Few learn to question the brief before writing it. Upstream is a daily training app for data analysts. Short cases from real workplace moments — a vague PM request, conflicting metrics, a rushed presentation. You decide how to respond. You get feedback. You sharpen. 5–15 min/day. Placement quiz to find your starting rank. A calibrated case path based on your role and pain points. The skill that makes analysts irreplaceable.
