Their man researcher has a PhD in Neuroscience and the lead guy has been researching and developing audio-neuro software for over 11 years.

Well, yes?!

Your implied complaint was that their work is not very scientific. The team having PhDs in neuroscience is irrelevant/unsatisfactory/bad?

What would you like to see? Would it have seemed more scientific to you if they'd done it at a hackathon?

Obviously irrelevant, which renders moot the other two questions that you asked me.

My point is that the work itself is what makes something scientific, not the workers' CVs (note the careful wording here; calling them researchers is another appeal to credentialism).

With that in mind, what would I like to see? You should be able to answer that one yourself now.
