Small team reviewing charts and financial notes
Our story

Started as internal financial notes, opened up to everyone

felixhui began as a set of internal notes kept by a small group of operators and early-stage advisors based in Košice, Slovakia, who kept re-explaining the same handful of financial concepts to founders they worked with. Eventually those notes turned into structured explainers, and we decided the material was more useful published openly than kept private.

Today, Startup Economic is maintained as a standalone, informational publication. We are not an accountancy, investment firm or consultancy, and we do not sell services, courses or memberships through this website.

What guides us

The principles behind every explainer

Accuracy over speed

We would rather publish an explainer two weeks late than publish one that hasn't been checked against reliable sources.

No sales agenda

We do not accept payment to feature a company favourably, and this site does not sell any product or service.

Written for the reader

Every explainer is written so a first-time founder and an experienced operator can both take something useful from it.

What we are not

A short, honest disclaimer

To keep expectations clear: felixhui does not provide paid consulting, coaching, legal advice, investment advice or financial advice. Content on this site is general and informational, and should not be treated as a substitute for professional advice specific to your situation. We do not process payments, sell subscriptions, or offer any commercial service through this website.
