Should I include side venture on resume?

Working as an IC in FANG, however I have cofounded a business with a friend and it is still in ealry stages (registered on blind using the side business address). Have an offshore development team, I mostly architect and manage somewhat. Got angel funded at about $2M valuation. We have a few customers as well who are using the product. Experience wise this has been the most exhilarating one, pitching to VCs, talking to potential customers, and also designing and developing a real product from scratch. It is not making much money, and all the money generated is being plowed back in further development. I cannot leave my job to work on it full time. But since this is AI and ML application within a product, it has good potential.

I am planning to move to management but not at the place where I am working currently(I have not disclosed my other venture). I am planning on applying to some other FANG and UL etc, should I include my experience as cofounder of this side venture? Or will it be taken as negative?
