Two things happened for me in 2009: I fulfilled a lifelong dream to become a private pilot, and I was intrigued by the new iPhone software so I decided to try it out.

I came up with a toy iPhone programming project just to get my feet wet. My idea was to capture a 3D flight track using the iPhone's internal GPS and display it on Google Earth. The initial toy project was a very basic GPS logger, yet after every flight, whether with friends or with my flight instructor, I rushed to my computer to look at the flight track. It became addictive.

By the time I started instrument training, the capabilities of what started as a toy project were vastly expanded. This new way of debriefing became an essential component of my training. With my foggles on, I was never sure how well I flew an instrument approach. My instructor, a man with infinite patience, kept correcting me during flight, and obviously a lot of what he said during flight was lost. I became dependent on analyzing my performance on my computer screen after every flight, and kept enhancing the program to help my debriefs. As the app became increasingly useful for me, I started sharing it with friends, and CloudAhoy was born.

Soon Etan Rozin, a UI designer, joined the team; Etan and I are best friends of many decades, and worked together on many projects in the past. Then Tani Shavit joined the team. She is a software engineer and a manager of software projects, large and small; Tani and I are not only husband and wife, we also worked together on many projects in the past.

CloudAhoy, Inc. was registered as a corporation in 2010, and version 1.0 of the app was released to the app store in the spring of 2011. The iPad came out and changed aviation forever, and in the summer of 2012 we released CloudAhoy 2.0, with in-app debrief. The user-base grew organically, by word of mouth, and the capabilities of the software have been rapidly expanded. Valuable feedback and requests from users have greatly shaped the development. While CloudAhoy was initially taught to analyze and help debrief maneuvers of fixed-wing flights including instrument approaches, helicopters pilots and gliders started to use it as well, and it was expanded to analyze rotorcraft and glider flights. This tight relationship with the users is fundamental to our approach, and we feel blessed to have it.

By the end of 2014 CloudAhoy has been our day job. We moved to a subscription model on December 2014, and have been growing since. We have customers all around the world. And we are in the best position any software developer can be in: we are users of our own product.

CloudAhoy, Inc. is self-funded, and is privately held.
