Metaphor.xyz was sold by Swetha from DNGear.com last month for $9,888. The domain names is now up and running and it looks like the company is involved in the DAO (Decentralized autonomous organization) space. They have a newsletter you can sign up for. They do not have many tweets only 31 and just a few hundred followers.
Defined.ai was sold by Grit Brokerage for $11,250. The buyer was DefinedCrowd Corporation. The company is a leading online marketplace for buying and selling AI data, tools and models, and offers professional services to help deliver success in complex machine learning projects.
I thought the sellers got great prices for both names.
