Caelum Labs

Caelum Labs is a Barcelona-based company that builds blockchain software for business process automation and self-sovereign digital identity. Its product, Caelum, lets companies share information and run workflows across organisations with decentralised authentication, traceability and interoperability, with privacy by default and GDPR compliance. The company was founded in 2017 by Alex Puig, who previously founded Alastria, the Spanish blockchain association. It raised a €500,000 round from technology-sector business angels to bring Caelum to market in Europe and expand into Latin America, where it has collaboration agreements in Colombia and Peru. Its backers include ATH21 and Kensington Capital.
