Tools for Humanity Tech Stack

Decentralized digital identity and proof-of-human verification at global scale

Technology, Information and Internet San Francisco 51–200 employees Founded 2019 Privately Held

Tools for Humanity builds World ID, a decentralized digital identity system pairing proof-of-human hardware with an Ethereum and OP Stack blockchain layer. The stack mixes AOSP and Rust for device software with a serverless AWS backend (Lambda, SQS, EventBridge, CDK). Legal hiring nearly rivals engineering and a Chief Compliance Officer search is open, so multi-jurisdiction regulatory risk is as central to scaling as the technology.
