DAR Software

This was an exciting venture. At the time, we took on building mobile apps for the iPhone. The iPhone 4 and iOS 4 had only just been released. In our country, that still felt almost unheard of. iPhones were extremely rare, yet we were already building apps that became popular all over the world.

That went on for several years, and we attended Macworld. The conference is gone now, but at the time it was a major event in downtown San Francisco, organized by Apple during the Steve Jobs era.

But after a while, we realized that building mobile apps was becoming less profitable because teams in lower-cost labor markets could reproduce them too easily. We quickly saw dozens of copies of our products appear in the App Store, shipped faster than ours. Reviews were being manipulated at scale, and we lost our advantage quickly.

The second threat came from Apple itself. What had once made our photo transfer app distinctive eventually became AirDrop, built right into the operating system. The same thing happened with many other apps: features that once required standalone tools turned into a simple button in the browser or another app.

We realized there was no point in continuing to fight in the market for small mobile apps, because the competition would only become more aggressive. The winner would no longer be the one with the best idea, but the one who could copy it faster and manipulate App Store rankings more effectively.

A student at the Technological University could only dream of getting a job at a company that makes software products and sells them worldwide.

It was a fantastic start to my professional career.

As a student with no programming experience, I found myself involved in a complex technological development project in which a small team was developing a 2D vector graphics product for two platforms: Windows and Macintosh.

At this company, I not only learned new things from the people I worked with but also had to navigate a variety of new technologies and development principles myself, thanks to the challenges they posed.

I joined this company as an intern to gain experience. After a while, I became the team's technical lead.

After some time, I noticed I was no longer as interested in writing code. I was interested in developing the product, looking well beyond the immediate functions in the Work Plan.

As often happens, my interests began to expand beyond the company, and the company couldn't satisfy my thirst for technology and self-improvement.

At this very same company, some truly unique things were happening, especially given that it was competing with giants like Microsoft, and people who had achieved one or two career advancements were constantly leaving. As soon as they began having conflicts with the company's director, absolutely everyone left.

What's remarkable is that in our city of Odessa, Ukraine, almost all the product companies that were created and founded by people working at this company, every time I think about it, a big question arises for me: what heights would this company have reached if all of us who created new businesses had stayed at that company and, thanks to the synergy of our efforts, made it truly world-famous?

Of course, this question remains rhetorical, and the main conclusion I've drawn is the need to take employees' opinions into account and stop considering myself the smartest. After all, any company in any given area develops only as much as it has top-notch specialists who lead it. And if you limit their freedom of action, freedom of thought, they will leave, and you will be left with only obedient sheep.
