Tools for Humanity, the company behind the crypto startup World, has secured a lease for 90,000 square feet in San Francisco's Showplace Square. This development comes after earlier negotiations for a new office space at Mission Rock near Oracle Park fell through. The startup, backed by Sam Altman, aims to integrate its World Wallet with Visa functionality, allowing users to load, send, and spend both stablecoins and fiat currency. The WorldApp has also been upgraded to include features such as virtual and physical Visa cards and access to high-yield savings accounts and investment options. The recent leasing agreement marks a significant step for the company as it continues to expand its presence in the cryptocurrency sector.
