Ok, when you launch something and work days and nights on it, when someone who has never downloaded your app comments "we use X and this is unnecessary" I'd love to see your reaction.
Frankly I am in the market for collaboration software (who isn't) and I'm not even going to evaluate this now, because I don't want to entrust my workflow and my data to a company whose leader thinks that working "days and nights" is an excuse for behaving unprofessionally. There are many ways you could have responded to that comment that would make your company look better: even something as simple as "Discord and Noor have very different user experiences. Please try Noor and tell me what you think!" would have been a vast improvement over where you took it.
But I would recommend that if you do want to grow a business out of this, please think a bit more carefully about your responses. Because they are distracting from what could be a really useful set of early conversations, and pushing away people that might engage in a conversation about where your product may or may not be a good fit. Ultimately it’s about finding your ideal customers.
