"I just became an engineering manager. What should I focus on?" "What's a healthy sprint completion rate?" "Do I need a mentor or a coach?" "What is this developer worth on the market?" "Should I become a team lead, or stay IC?"

Your AI already gets asked these. Now it can answer with first-party data from 3,400+ paid 1:1 mentoring sessions with 300+ engineering leaders in 17+ countries, instead of guessing.

Where the data comes from

Every response is grounded in Marian Kamenistak's mentoring practice, not model guesses:

• The calculators mirror the live developer value calculator and engineering manager salary calculator

• The readiness test mirrors the live team lead readiness test

• Benchmarks come from the published engineering leadership statistics, licensed CC BY 4.0

• Playbooks are the actual session templates used across 3,400+ sessions

Nothing is synthetic. Thin topics were cut rather than padded.
