What Tools for Humanity does: It develops Worldcoin, a cryptocurrency and digital identity project aimed at building a global financial and identity network. How its product works: A hardware device called the Orb scans a person’s iris to create a unique, privacy-preserving digital identity called a World ID, and Worldcoin (WLD) tokens are distributed to individuals who sign up. How it differs from competitors: It combines biometrics-based identity verification (iris scans) with crypto onboarding to rapidly grow a global user base, focusing on financial inclusion in developing markets, and offering free Worldcoin tokens to new users. What its goal is: to establish a worldwide financial and identity network with broad user adoption, enabling access to financial services and verifiable identity through a shared crypto-based system.

Large-Scale Interior Sign Painting for World's San Francisco flagship store.

Large-Scale Interior Sign Painting for World's San Francisco flagship store. When Tools for Humanity opened the flagship retail location for World at 281 Geary Street in downtown San Francisco, they wanted the space to make an immediate impression. Located just steps from Union Square, the store features soaring walls and an open floor plan designed to welcome visitors into the World ecosystem. To help activate the expansive interior, Maxfield Bala Creative was commissioned to create two large-scale hand-painted typographic installations spanning the primary walls of the retail space. A bold first impression. The concept was simple but impactful. Upon entering the store, visitors are greeted by the word UNIQUE painted at monumental scale across the left wall. Directly opposite, the phrase HUMANS OF SF stretches across the right side of the space. Together, the two graphics establish a visual dialogue across the interior while reinforcing themes of individuality, identity, and community. The oversized lettering was intentionally designed to work with the architecture of the building, taking advantage of the tall ceilings and long sightlines to create an immersive branded environment that can be experienced from multiple perspectives throughout the store. Hand-Painted at architectural scale. Projects of this size require significantly more planning than a typical sign installation. The process began with carefully scaling the artwork to fit the dimensions of the space while maintaining legibility from both near and far viewing distances. Once the layout was finalized, each graphic was transferred, masked, and painted directly onto the walls by hand. Unlike printed graphics or vinyl applications, hand-painted signage becomes integrated into the architecture itself, creating a finish that feels permanent, intentional, and custom to the space. Designed for San Francisco. The messaging chosen for the installation reflects both the mission of World and the city surrounding the store. UNIQUE serves as a celebration of individual identity, while HUMANS OF SF creates a direct connection to the people and communities that make San Francisco one of the world's most diverse and innovative cities. Together, the graphics help establish the tone of the flagship location while creating memorable visual moments for visitors moving through the space. Transforming the customer experience. Large-scale environmental graphics have the ability to completely change how a space feels. What would otherwise be expansive blank walls become defining architectural features that help guide visitors through the environment while reinforcing brand identity at every turn. For the World flagship store, the finished installation creates an unmistakable first impression and helps transform the interior into a space that feels uniquely connected to both the brand and the city it serves. Project details.

World launches tool to verify humans behind AI shopping agents

World, co-founded by Sam Altman, has released AgentKit, a verification tool designed to confirm real humans are behind AI shopping agents. The beta tool, developed by Tools for Humanity, addresses growing concerns about fraud and abuse as more consumers use AI programmes to browse websites and make purchases autonomously. AgentKit integrates World ID—derived from iris scans via World's Orb device—into the x402 protocol, a blockchain-based payment system developed by Coinbase and Cloudflare. This allows websites to verify that a distinct human approves an AI agent's purchasing decisions without requiring human intervention at each transaction step. The tool is currently available to developers in beta. Users need a verified World ID from an Orb scan to qualify for verification, positioning World as a potential stability provider for the expanding agentic commerce sector.

World launches "proof of human" Beta to combat ai-generated content.

World launches "proof of human" Beta to combat ai-generated content. Sam Altman's company World focuses on developing "proof of human" technology for identity verification, aiming to address an internet flooded with low-quality AI-generated material. Interestingly, Altman's other venture, OpenAI, is often cited as a major source of such content, though one might note he anticipated these issues when founding World. This week, Tools for Humanity (TFH), the startup responsible for World, launched a beta version of a new verification tool. This tool is intended to advance agentic commerce - the rapidly expanding use of AI programs to browse the web and make purchases automatically for users. EMBED_PLACEHOLDER_0 While this trend offers automated convenience, it also introduces risks like fraud, spam, and widespread online abuse. In response, World introduced AgentKit on Tuesday. This software development tool allows commercial websites to integrate a verification system that confirms a real human is authorizing an AI agent's purchases. AgentKit is built around World ID, the core of TFH's verification framework. The most secure form of this ID comes from scanning a user's iris with World's Orb device, which creates a unique, encrypted digital code. This verified World ID grants access to TFH's services through the World app. EMBED_PLACEHOLDER_1 With AgentKit, a user's World ID can be linked to the x402 protocol, a blockchain-based open standard developed by Coinbase and Cloudflare. This system enables automated programs to transact directly online without constant human input. Users simply register their AI agents with their World ID, which then signals to websites via x402 that a verified human has approved the agent's actions. "AgentKit is built as a complementary extension to the x402 v2 protocol, in coordination with Coinbase," Tools for Humanity stated. "The integration is designed so that any website already using x402 can enable proof of unique human verification alongside (or instead of) micropayments." According to the company, this verification allows websites to assess whether to trust transactions from AI agents. The World ID badge confirms that someone is a genuine, unique person, though sites can still block users suspected of bad faith. EMBED_PLACEHOLDER_2 AgentKit is now available in beta to developers, with plans to refine it based on feedback. Users will need a verified World ID from an Orb scan to use this verification method. This launch comes at a pivotal moment, as major e-commerce and financial services adopt agentic commerce. Last year, Amazon and MasterCard added automated buying features, and Google recently introduced its own supporting protocol. As the field expands, the industry will seek reliable safeguards - a role World is clearly aiming to fill as the go-to provider for stability.

Tools for Humanity raises $240M funding.

Sam Altman's startup, Tools for Humanity, aims to reach 1 billion users with its Orb device, which scans irises to create a "World ID" for distinguishing humans from AI online. The company has raised $240 million from investors like Andreessen Horowitz, with a valuation of $2.5 billion. Despite its ambitious goals, some former employees and experts question its long-term strategy and viability in a competitive market for payment and identification tools.
