MarkUpgrade was founded in 2018 by “a small group of entrepreneurs” led by Tatiana Bonneau. The mystery-shrouded domain branding company leverages a portfolio of solid domains and they are priced accordingly.
MarkUpgrade’s mission is to connect the best domain names available globally to the most suitable companies for them, according to their web site at MarkUpgrade.com.
