Run the numbers
before you trust your gut.
Every real decision in business and your career comes down to a number you can actually check. This is where you check it — before you commit the money, the offer, or the year.
Assessments
3Validated instruments — Big Five, RIASEC, burnout — scored the way researchers score them, not the pop-quiz versions.
Big Five Personality Test
The full IPIP-NEO-120 — five traits, thirty facets. The framework academic psychology actually uses, not a pop quiz.
Salary & compensation
4Real total-comp breakdowns by level, company, and specialization — base, equity, and bonus, not just the headline base number.

Freelance & consulting
1Anchor your rate to BLS wage data and industry survey benchmarks, by experience tier and pricing model.
Education & ROI
2The true cost of a degree at a named school — net tuition, city living, and the salary you give up — not the sticker the brochure shows.
Simulations
6Decision games. Run a t-shirt brand, survive a burn rate, balance a traffic funnel — concepts you learn by breaking them.
Shirt Boss
Run a t-shirt brand from scratch. You make decisions about sourcing, design, marketing, and pricing — then see if you turn a profit.
Burn Rate Simulator
You have funding and a team. Every month costs money. Balance growth and survival to keep your startup alive as long as possible.
Traffic & Unit Economics
See how traffic, conversion rate, and acquisition cost are connected. Change one number and watch what happens to the rest.
Strategy Audit
You have a startup idea and $1,000. Build it, test it, or ask friends? Each choice leads to a different outcome.
Every tool sits on top of a course.
The calculators give you the number. The courses give you the reasoning behind it — when the benchmark applies, when it lies, and what to do next.
