What is InSimu?
InSimu is a medical startup company aimed to provide a virtual simulation on an application platform designed specifically for medical students to practice their future diagnostic ability in the safety of virtual reality.
The medical students / or anyone / who uses the app is taking the path of a real doctor in a primary care setting. You start from the point where the patient comes in, tells you their complaints up until the point where you have the correct diagnosis of the virtual patient. Anything that happens within this situation is monitored and measured for later evaluation and feedback.
InSimu’s primary goal was to help medical students to practice the diagnostic experience before they are training on real lives.

I’ve been asked to join InSimu just after the initial round of funding to build up the medical database, the virtual hospital environment and to create the medical cases in cooperation with the IT team.
First, I dove deep into the basics of the current, early-stage MVP to fully understand the product and the company’s vision. This would allow me to build and expand the medical database in alignment with the founders’ goals.

I had the great pleasure of working with David during his time as Senior Product Manager at Medmastery. He played a key role in improving our online learning platform for doctors and other healthcare professionals.
David has a sharp eye for detail, strong product skills, and the rare ability to both shape a clear product vision and deliver on it. He made a real difference to our team.
If you ever get the chance to work with David - take it. I truly enjoyed working with him and wish we were still on the same team. Thanks for everything, David, and all the best for what’s next.

Franz Weisbauer MD MPH
CEO at Medmastery

David’s hard-working, self-driven attitude and his previous success in increasing one of our clinic’s business efficiency and meeting target revenue numbers led me to trust him with the additional role and responsibility of leading that specific clinic’s operation as an operational manager.
Despite his young age, David had an exceptional eye for recognizing the developmental possibilities within the company. He had shown us his unique ability to adapt to the fast-changing environment of our company.

Gergely Fabian
CEO at TritonLife

Throughout the project, David’s excellent organizational skills proven to be a determining factor in the successful completion of the project, despite very tight deadlines, numerous changes in project requirements and complications.
David was able to effectively gather and translate project requirements despite the fact that only general guidance and basic design elements were available at the onset of the project. David’s weekly progress updates were succinct and informative.
The end product was of very high quality.
In conclusions, based on my experience,
I do not hesitate to recommend David Szalay.

I’ve really connected with InSimu’s vision about providing a platform that allows medical students to have a better clinical education, to reduce the abyss of real life decision making.
I loved taking part and using my medical kowledge in building something, in this case InSimu from the ground up.
I loved pushing the boundaries of the current medical knowledge by trying to implement it into a virtual simulation, asking questions that we had to find answers for.
I’ve widened my medical knowledge, and started using technological terms, understood how changes are implemented in an application, how merging codes work.
I’m immensely grateful for the opportunity to Dr. Tóth Gábor, Tamás Katona, Andrea Herdon.
