Ask HN: Empty Delaware C Corp, dissolve, hand-over, or?

I had a profitable product, a company in the UK running it, and things were looking great. When Stripe's Atlas program launched, I was one of the first to incorporate in Delaware, hoping to take my product and all my future business there (making things potentially easier for handing over the product, or seeking a potential growth-investment).

Once everything was ready, the environment my product operates in started changing dramatically, and things became sour. I decided to hold off transferring everything to the US company, and keep it fresh and clean while I see if things would improve on the product side.

Two years in, they didn't.

I'm basically paying the yearly franchise tax ($450) plus registered agent, plus TaxAct 1120 filing fees ($97 for federal/state taxes) and will soon have spent a couple thousand dollars to keep the empty shell alive.

I looked into closing it down, which, again, involves fees and more fees, but will probably be my next step.

Are there any other venues some of you have taken, or can suggest? Is it worth considering to hand-over (for a modest fee) the company as a starting point for someone else?

Part of me thinks it may be useful to keep the US company around, but the "useful" part hasn't really come up in the past two years. I know there's potential to use it as a legal and proper way of entering the US with a work permit, but I'm not sure if that's really worth considering.

Still in the UK at the moment.
