About Mass Labs We are building Mass Market: the next generation commerce protocol for physical items, utilising blockchain technologies to redirect data ownership and control back into users’ hands. Mass Labs is co-founded by an ex-Ethereum core dev with a passion for decentralised systems. The company is currently very small and pre-funding: you will be a super early employee and as such we expect you to take ownership of your work, be highly collaborative and passionate about crafting excellent code. Our goal is to build for the long-term, architecting top quality software systems that will last generations.
