How did it all start?

The initial spark for Carly arose from a personal problem. In 2014, Parvis – Avid and Arian’s father – had issues with his own car, a used BMW 7 Series. He spent a significant amount of money in workshops, often dealing with problems that couldn’t be easily identified on his own. Obviously, this was frustrating. He realized that there were limited options in the market for ordinary car owners to access their vehicle’s technical data; it was primarily reserved for workshops.

Since no one had addressed this issue, Parvis and his son Arian, both software experts and computer enthusiasts, decided to create a solution for their own use. The solution showed them that the car simply required a small electronic component worth just a few euros, and not an expensive repair – saving them €7,000.

This inspired them to develop an easy-to-use diagnostic device that anyone could use. They told Avid about the product and he immediately recognized its potential. Together with their good friend David Grotzky, they crafted a business plan and spoke with other car enthusiasts to gather input on crucial functions. After introducing their first prototype, they quickly realized that there was a huge audience eager to try their product. From that point on, things really took off.
