About CrossmintAt Crossmint we're on a mission to bring the world on-chain. This is an urgent and important matter: As artificial intelligence advances, the lines of what is real and not, are blurring – fostering a growing issue of bot spam, disinformation, deepfakes, and corruption. By bringing the world on-chain, we can create cryptographic proofs that restore our ability to discern what is true, vs not.How do we do this?Crossmint is accelerating this transition, by building APIs and tools that make it 100x easier to create, custody and commerce with digital assets (NFTs) and verifiable credentials (VCs). Our APIs abstract out all the complexities of interacting with blockchains to simple REST APIs and no-code tools that any company can adopt, in minutes.How do we fund this mission?We sell our tools and APIs as a service to other companies who wish to integrate NFTs, wallets or credentials inside their systems. We save these companies hundreds of thousands of dollars in infrastructure and engineering, and charge them a fraction to manage all for them in a secure, compliant and low maintenance way. More than 30,000 devs and companies have used us, including Mastercard, Microsoft, Etihad Airways, Red Bull, Adidas, Asus, AC Milan, Phantom, Rarible, Refik Anadol, and Snoop Dogg.In addition, Crossmint is backed by top tier investors and angels in the fintech and crypto space.Who are we looking for?We are looking for folks with extreme ownership, competence and integrity.
