advice Selling Domain with Long Term Business Deal

Not sure if there is any such guidelines on NP but that'd really be a great setup. However, I am not aware of any such contracts, at least from my network.

Most of the startups are listed on Producthunt, Betalist and even on Crunchbase; You should contact founders and CEOs there and pitch on your offer. Rest of the story depends on how good your domain is and how much they offer against your domain.

Let us know if you could win any contract and what you've gained.
