And my point is — how do you, as a startup founder, judge whether .NET — or any other platform, for that matter — increases your developers’ productivity by N percent? You certainly don’t have the time or resources to build the MVP on every major platform and measure. More often than not, startups go with whatever their first few developers are comfortable with. And, once you have started with Java/Python, why would you want to spend your money on licensing costs AND .NET developers who, from personal experience, often tend to be more expensive and harder to hire than Java/Python/Go developers? Licensing costs don’t matter a lot if you already have a team that is proficient in .NET. It’s a Catch-22 situation. Why would want to spend money on building a team of .NET developers in the first place unless you have some hard evidence that using .NET is going to help your business significantly?
