S73 is the public brand of 1973 SIRIUS LLC, a company organized in New York and established in 2022. The company operates from New York, United States, and conducts its business in the U.S. market.
S73 runs six business areas under one roof: Books & Media, Software & Technology, DTF Printing & Custom Production, Wholesale & Distribution, Marketplace & Ecommerce, and Consulting & Advisory. Each area runs to the same operating standard, and daily operations are supported by software the company builds in house.
The company takes a long term view of its work. It would rather do fewer things properly than many things quickly, and it holds itself to standards a counterparty can verify: correct listings, steady pricing, and clear communication.
