Serious Red Flags With Co-founders. How To Proceed?

I'm not going to go into too many details and I'm likely to delete this message after I've gotten my consensus from the community. I'm gonna give my situation (position), then scenario I'm in. Let me know what you think?

About me:

Main tech cofounder

AI + Web + real-time financial systems

Last 5 months developing quant app

Here's the gist of the situation I'm in:

I happened to find a highly connected team that is filled with a bunch of non-technical people.

They want to build a financial app, yet they don't know what they want. They're asking for things, yet don't think them out. Then raise a fuss.

I've been working on a particular app then changed directions in the last month because they complained. Yet, see point above.

Met them online. They allude to a structure outside of the company, yet ultimately aren't giving much information outside of my percentage of equity.

There's another dev that cant deliver the same amount of time and i found out his equity from him. He was fairly honest.

If i ask them what the structure is they say "doesn't matter, stay in your lane. Everything is taken care of. "

The fact that they hide so much bothers me. It makes me feel like I'm just a grunt that's nothing but a tool to them, and that I'm getting the short end of the stick.

The above point alone is making me reconsider them as a group. My thought, why care about sharing information if there's 0 stake? Sharing info will take 30 mins. Basically zero effort.

I have code I've yet to share because I don't fully trust them. They aren't doing things to get me to trust them. The things I want are clarity and transparency.

I've been thinking about quitting them for weeks because they've yet to do the necessary things to get things straight.

There's more information than this that I'm not sharing. I'll leave things here for now. How should I proceed forward?
