What is even fish's vision? Just do what works?
Until now his company just goes on track by 1. being edgy and 2. not being terrible, but is he trying to go anywhere?
We're gonna' become idols, man. We're going to fix everybody up and turn them into idols -Fishman
Timestamp (coincidentally leads into the famous "If Tenma doesn't talk, she's the perfect idol" quote and the aftermath of that):
Things do seem to be progressing a bit slow, for sure. While some of it seems to be calculated to make sure they get it right, there's also much of it outside of their control. They even talk about this later on in this interview when someone also brings up a music budget for Michiru. The money is there for it, but there's a lot more that goes into it than just recording the song a lot of the time. Just as he said, the biggest delay is normally in the art because, as he also said, artists are prone to "getting sick". Probably why Uruka's goal of releasing a new original every month was dead in the water immediately.

But then you look at Lumi, for example. She puts out covers more frequently than almost all, if not all, of the other Phase girls. One of the big reasons is probably because she doesn't put out that many fancy music videos. It's just her model, her singing, and maybe some nice backgrounds and filters. If you look at the credits, most of the time, she does everything. For some of them, she'll get someone to do the mixing. So she's not really waiting on people to do things. It's usually just on her. Would definitely speed up the process for the rest of them to do something similar at times, or maybe look into releasing albums/EPs (I'm sure some probably are doing this), instead of fancy music videos all the time, but it is what it is.
And speaking of Lumi, she claimed that, hopefully, some 3D might be rolling out later this year or early next year. All dependent on the artists, I'm sure.
It's definitely an uphill battle, but thankfully, Phase has somehow wrangled all these women to at least be happy enough to stay in the company and try to contribute to his goals and build up the company. They've been doing great with what they have, so hopefully a little more patience will pay off.
