I recently had the idea to bring it back, and found the domain was available, so I bought it.
I also found the trademark marked ABANDONED/DEAD.
The company raised a small round of funding, and was popular for about a year in certain Twitter circles.
It likely has some brand recognition among those in the startup crowd.
I've tried to reach the founders and others on the original team multiple times via multiple methods, to no response.
I'd prefer to get their consent - but interested to hear whether you think it'd be OK to just go ahead and reopen the site?
My biggest concern would be that if it has brand recognition there is value there and if there is value ... it is likely that someone might feel they still own it, and maybe only after you get some success.
I like the idea of asking but asking the right person might be more of a confusing thing depending on whomever was involved in the past endeavor. Someone might ok it... but are they the right someone?
https://en.wikipedia.org/wiki/United_States_trademark_law:
”Common law trademark rights are acquired automatically when a business uses a name or logo in commerce, and are enforceable in state courts. Marks registered with the U.S. Patent and Trademark Office are given a higher degree of protection in federal courts than unregistered marks“

A dead trademark is not always available for use or registration by someone else because the original registrant might still be using it, and thus retain common law trademark rights. Search the USPTO website to learn why the trademark was abandoned. You might be able to acquire the trademark depending on the circumstances of its abandonment.
Before using an abandoned trademark, speak to a trademark and branding attorney and find out why the application was abandoned.
You must clear the rights before using the mark.
If the mark has been abandoned for three to five years, most likely you're safe. But beware that a non-active mark in the USPTO database could still be in use by the original owner. Even if you prove that the original owner has no intention of using it again, you still risk legal problems.
Make sure to also check all countries where the mark was used.
This is from a moral, not a legal perspective.
