Why did I get rejected?

I, like of 1000's of entrepreneurs like me, applied to YC earlier this year. And like 1000's of others, got the unfortunate message, that I was not accepted into the program. And looking back, my application and venture, was not ready for YC. But why? And will we ever be?

The following are my thoughts on why were rejected, and a few concerns which still slumber in the back of my mind: I believe that 3 main issues caused our application to be firmly placed in the rejected pile. I do not believe that it was a close call.

The number 1 reason: Team. Originally, I had the idea for my startup 5 years ago, and since then I have moved continent, started a family, gotten jobs, left jobs, and struggled to launch my startup. I guess, one of the side-effects of moving country is your network goes from level 80, to level 0. I tried some cofounder dating, and actually found a great CTO to join me, but after 2 months of working together, he was asked to become the new Vice Minister of Technology for the country, and therefore had to quit the startup. Thereafter, I "convinced" a technical and strategic partner to join my company, even though we lived 7 timezones apart, we believed that we could manage (spoiler alert, we couldn't). The project was not moving ahead at the pace we wanted it. And finally, my new CTO quit, after being offered a senior position at AWS. Alone again... I am now working with a former co-worker, and friend, but he has been clear from the beginning, that is not interested in the CTO position. He wishes to continue his employment for the coming 5 years or so. In the same period, I found a CMO to join the team, but that didn't work out either, as I felt he was not invested in the project.
