The Origin of Mercari or Poshmark
“Mercari” and “Poshmark” are brand names, not alternative spellings of the same English word. Therefore, the usual spelling rules that apply to words such as “color/colour” or “practice/practise” do not apply here.
Mercari is the name of the Japanese-founded marketplace company. Mercari launched its U.S. marketplace in 2014 and has continued developing its U.S. business.
Poshmark was founded in 2011 by Manish Chandra, Tracy Sun, Gautam Golwala, and Chetan Pungaliya. The company began with the idea of combining shopping, selling, and social interaction.
So, if you see Mercari and Poshmark, you are not looking at two spellings of one word. You are looking at the names of two different marketplaces.
