At 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 what is 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 and what is 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 credentials (VCs).
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 developers 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 individuals with extreme ownership, competence, and integrity. Our team includes math olympiad winners, Guinness world record holders, athletes, music composers, empaths, and degens. Diverse applicants are encouraged to apply.
