Reviews

What learners say.

"I used Greeks every morning for 6 weeks before my PE interviews. The LBO and waterfall cards alone were worth it — the explanations are sharper than most textbooks."

Thomas R. Private Equity Associate

"The quiz format forces you to actually recall the material, not just read it. After two months, I noticed a real difference in how quickly I could reason through technical questions."

Camille D. MSc Finance Student, HEC Paris

"Most finance apps talk down to you. Greeks doesn't. The macro and quantitative content is genuinely rigorous — exactly what I needed transitioning from engineering into finance."
