We’re building an Ethereum L2 that introduces blended execution. This is a new way to build where multiple virtual machines (EVM, Wasm & SVM) run in the same state, letting developers use tools from different environments inside one app, with seamless interaction across VMs and no bridges, fragmentation or UX tradeoffs. This results in more expressivity, faster experimentation and entirely new kinds of applications.

We are an ambitious, fast growing and international team working at the forefront of DeFi. We believe that we can make markets both more efficient and fair, by building the ultimate batch auction settlement layer across EVM compatible blockchains.

From the Middle East to Africa and the Americas, The Energy Year’s annual reports are known as a primary source of information for energy investors and are used by public and private sector actors to identify new investment opportunities and establish long-lasting collaborations.

FairwAI is building real-time accountability infrastructure to detect bias in the moments that matter most. We’re solving one of the toughest challenges in tech: how to make fairness not just a principle but a system. From healthcare and hiring to hospitality and housing, bias shows up when people are most vulnerable. FairwAI turns those moments into measurable, actionable data—using AI, computer vision, and behavioral science to flag risks and enable institutional change before harm happens. We’re not a DEI tool. We’re compliance infrastructure for a new era—where safety, dignity, and fairness are non-negotiable. Our team includes engineers, policy thinkers, civil rights advocates, and public interest technologists from MIT, Harvard, Stanford, The UN, and beyond. We’re launching high-impact projects and building the backbone of ethical AI adoption across sectors. For interns & fellows, this is not a coffee-run experience. You’ll co-design tools, analyze live scenarios, and help shape the future of bias detection and remediation. Your work will be mentored, respected, and turned into real-world impact. If you care about fairness, ethics, and building tools that actually change lives—FairwAI is where your skills meet purpose. Join us. Let’s build the infrastructure fairness deserves.

Hi! We are ElevenYellow We're a dynamic, creative software lab driven by a passionate team of entrepreneurial innovators. We don't just build software: we push the limits of what's possible, crafting game-changing projects that leave a lasting impact. Our culture is built on flexibility, collaboration, and an insatiable curiosity, giving us the freedom to explore, create, experiment and disrupt in exciting new ways. With over a decade of transforming bold ideas into groundbreaking reality, we're nowhere near done. Honestly, it’s pretty hard to sum up what we do - and we mean that in the best way possible. We’re the kind of company where, when your friends and family ask what you do for work, you’ll probably just shrug and say, “It’s complicated.” And we wouldn’t have it any other way.
