Insider EdVentures is run by its two founders, Nicolas Olsa and Szilárd Máté. We write the material, build the platforms and answer student questions ourselves. This page covers who we are, what our students have achieved, and how we measure it.
We judge our work by one outcome: whether students get into the programme they applied for.
Across the BBE, WISO and WIRE entrance exams at WU Vienna, the GMAT and the SAT.
Our students sit the same exams, but they prepare from 122 different countries.
Of the students who completed at least 90% of their course, 8 in 10 were admitted to the university they applied for.
The 80% figure counts only students who completed at least 90% of their course. It is not an admission guarantee, and Insider EdVentures is not affiliated with WU Vienna or any other university.
In 2023 we launched BBE Insider, a single platform for a single exam: the BBE entrance test at WU Vienna. Most prep we had seen covered a whole category of tests with one shared question bank. The problem is that an entrance exam is specific. Its question types, its timing and the way it is scored are its own, and generic practice does not train you for them.
So we built the opposite. Material written to the real format, full-length mocks under real timing, and analytics that show which topics are costing you points. We then applied the same approach to other exams, one at a time: WISO Insider, WIRE Insider, GMAT Insider and SAT Insider each cover a single exam and nothing else.
We are still a founder-led company. I answer student questions myself, and when a student reports a mistake in a task, we fix it. Szilárd builds and runs the software every platform is built on. If something on one of our platforms is wrong, it is on us, and you can tell us directly.
Master your Bachelor of Business Economics entrance exam with our comprehensive prep tools & strategies.

Unlock your potential for top business schools with our upcoming GMAT preparation platform.
Master business law with insider-focused preparation tailored for WU students.
Broader university entrance exam preparation, built on the methods behind our existing platforms.
Students who prepared with us, in their own words: how they studied, what the exam was like, and where they got in.
Two founders who split the work: Nicolas is responsible for what students learn, Szilárd for the platforms they learn on.
Co-founder & CEO
Nicolas started BBE Insider in 2023 and leads the company. He decides which exams we cover, oversees the course material, and is the person students reach when they write in.
Co-founder & CTO
Szilárd builds the software behind every Insider platform. One shared codebase means a fix or a new feature reaches every exam at once, while each platform keeps its own exam's format.
Four rules that apply to every platform we run.
Every platform covers a single exam. When that exam's syllabus changes, only its platform changes with it.
Questions are written to the exam's format, difficulty and phrasing, and mocks run under the real timing.
Questions about the material, the exam or the admissions process are answered by us, usually within a few hours.
Students can report an error from inside a task. When they do, we correct it on the platform.

I got in this year and ranked 32nd. I most likely wouldn’t have done it without BBE Insider. If you are determined to study at WU Vienna, you shouldn’t hesitate to buy the course.

I assert you that it’s an extraordinary tool if you put in the work. I owe my 46th place not only to my work ethic, but to the BBE Insider course, its tasks and simulations, and consistent support from its creator Nikolas - I could rely on any time I needed it. I can definitely state that had I not purchased it I wouldn’t have gotten in doing all other things alone.

Der WISO Insider Kurs war der entscheidende Erfolgsfaktor für meinen Platz an der WU! Besonders hervorheben möchte ich die Übungsbeispiele, die extrem nah an den echten Aufnahmeprüfungsaufgaben dran sind. Dadurch wusste ich beim Test ganz genau, was auf mich zukommt – keine Überraschungen, keine Unsicherheit.

Der Kurs war eine große Hilfe und perfekt zum Lernen aufgebaut. Dank der verständlichen Inhalte und der guten Struktur konnte ich mich optimal vorbereiten und habe die Prüfung erfolgreich bestanden. Ich kann den Kurs auf jeden Fall weiterempfehlen!

I purchased BBE Insider last September when my skills and overall knowledge were quite limited. I was not sure whether I would be able to comprehend all the chapters and be prepared by the end of June. This course provides thorough and detailed lessons, which make learning remarkably easier and far more logical. Aside from theory, the material also includes numerous different tasks that help students test their acquired knowledge. I can gladly recommend this course to anyone who is interested in the BBE program and have no doubt that after completing it, they will have considerably higher chances of being accepted.

I mainly bought this course to catch up on Maths again after being out of school for a while. The greatest value is probably the amount of tasks with solutions which I would add to my studying. For the econ part of the exam the tasks based on the script covered pretty much everything as well.

I have been using the course for over a month now, and I find this course to be a really good and complete one. Tons of exercises and content that are very helpful towards the preparation for the test. It definitely helped me focus my energy and time towards the most important content and task format, a must-have for a smart WU BBE prep.

Great course, which covers everything you need to know to be well prepared for the BBE entrance Exam. You can ask anything about Math, Economics and English content but also about general stuff about WU and the selection procedure. Usually you receive a response within a few hours. Definitely a great advantage if you take preparing for the BBE entrance exam seriously. Absolutely worth it.

Personally, what helped me the most was that the course provides an effective learning strategy that helps you study more efficiently and save a significant amount of time throughout the entire preparation process. I would definitely recommend this course to everyone who wants to secure a spot in the programme!

This course was extremely useful for my preparation for the BBE entrance exam. It included tons of questions, many of which were taken from previous exams. Mock exam was also great and it definitely felt similar to the actual BBE exam. Overall, I can assure you that this course is totally worth the money.

The website is amazing! The way the website is structured helps you cover all maths topics in depth and has a variety of economics tasks to help you prepare for the exam. The good thing about the course is that it doesn’t just give you tasks with answers but runs you through all the necessary material for every topic. I feel very confident in me getting in and would recommend this course to anyone who wants a big chance to get in to BBE
BBE Insider · Apr 2026
An awesome preparation tool, I can't imagine preparing for the exam without it. There are dozens of tasks for each topic which allows you to be ready for any question. I definitely feel very confident in my knowledge after taking this course! And I especially like the mock exam feature that simulates the exam. The only con I can think of is that there was a very small number of mistakes or inaccuracies in the tasks, but they are rare and there's a great reporting feature for them so the team quickly fixes everything.
Each platform covers one exam end to end. If you have a question before you start, write to Nicolas directly.
