We in https://digitalnomads.software/en think about this question more than half year.
Firstly we was mobile developers team. Our market research can't give answer on this question. Our customers was from startups to big market-forming products. We tried to get "ideal customer portrait", but all clients too much different, that we cannot unite more than 3 in one group.
Just a couple of weeks ago I heared one phrase from my friend: "I cannot find a reliable team for a month to solve my problem". After two days we setup 3 specialists, who starting work on this project. And I understand, that we are not only IT company, but we are team-makers for our customers. And our main advantage here over the rest is speed. We can form a team fast it possible.
So, If you are in searching for IT dev team - feel free to message me :)
