The posting

About the Company:

Tools for Humanity (TFH) designs and builds technology behind World. World is building a real human network designed to accelerate people in the age of AI. As bots and autonomous agents reshape the internet, people, institutions, and applications need a trusted way to confirm who is a real human while preserving privacy. The TFH and World tech stacks make this possible: the Orb verifies real, unique people, World ID proves it privately, and World App puts these capabilities, and more, in people’s hands. Together, they add a human layer to an AI-driven internet.

World is already running at a global scale. More than 17 million people across 160 countries have verified with World ID, and more new Orb verifications take place each week. World App is already among the most used wallets globally. Developers are integrating World ID to build safer online experiences and create spaces where real people can participate, earn, and be recognized in ways AI simply can’t replicate.

Founded in 2019, TFH has more than 400 people across hardware, software, AI, cryptography, mobile engineering, and global operations. Our teams come from OpenAI, Tesla, SpaceX, Apple, Google, Stripe, Meta, Coinbase, Palantir and MIT Media Lab. We’re backed by leading investors, including a16z, Khosla Ventures, Bain Capital Crypto, Blockchain Capital, Variant, Tiger Global, and Coinbase Ventures, as well as prominent operators and founders across fintech and AI.

TFH and World have been featured on the cover of TIME Magazine https://time.com/7288387/sam-altman-orb-tools-for-humanity/, highlighted in Fast Company’s https://www.fastcompany.com/91411606/fintech-blockchain-next-big-things-in-tech-2025 Next 5 in Fintech, and explored in a Bloomberg deep dive https://www.bloomberg.com/news/features/2024-08-12/how-worldcoin-is-building-digital-ids-to-combat-the-ai-apocalypse. The New York Times https://www.nytimes.com/2025/05/03/technology/world-eye-scanning-crypto-orbs-launch-in-us.html, Bankless https://www.youtube.com/watch?v=KUcjtFOHgNc and TechCrunch https://techcrunch.com/2025/04/30/world-partners-with-tinder-visa-to-bring-its-id-verifying-tech-to-more-places/ have all recognized our collective progress in identity, cryptography, AI, and global-scale hardware deployment. Our leadership is also named to the Time AI 100 https://time.com/collections/time100-ai-2025/. Learn more about the newest product launches from our Liftoff https://world.org/liftoff event.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
