## What is Upstream?

Upstream is a thinking gym for data analysts. Instead of teaching SQL or dashboards, it trains the skill that matters most: knowing what to ask before you query.

HOW IT WORKS
You're dropped into realistic workplace scenarios — a stakeholder wants a "quick report," retention looks suspiciously good, or an A/B test shows no lift. Each case challenges you to think critically, ask better questions, and resist the urge to just pull the numbers.

Choose your approach at each step. Do you dig into the data immediately, or push back on the request? Challenge the metric definition, or accept it at face value? Every choice reveals how a real analyst would navigate the situation.

FEATURES

30+ interactive cases inspired by real data team challenges
Placement quiz to assess your analytical instincts and assign your starting rank
Four analyst ranks: Query Runner, Report Builder, Sharp Analyst, Question Architect
Scoring system that rewards critical thinking over speed
Progressive unlock system — earn points to access harder cases
Skill tracking across categories like stakeholder management, metric design, and root cause analysis
Clean, focused interface with no distractions
WHO IT'S FOR

Junior data analysts looking to level up their thinking
Senior analysts who want to stay sharp
Analytics managers who want a training tool for their team
Anyone preparing for data analyst interviews
Students learning what real analytical work looks like
