Gemr

Gemr (initially Attic Gem) was a Nashua, New Hampshire-based online e-commerce social platform for collectors that raised a $4.9m Series A round of financing in November 2014. 
Gemr acquired GoAntiques in May 2015, and later sold it in March 2018.
In September 2017, Gemr signed a partnership agreement with Loot Anime to create the first officially branded club on the collector platform.
on January 27th, 2020, gemr announced it was shutting down after it was unable to get additional funding to keep the company going.
