We’re an end-to-end solution for launching, upskilling, or switching into a career in AI & data. We deliver an immersive programme that launches careers in Ai & Data at supersonic speed. Over 18 weeks, users log into the AiCore Portal, which gives them access to a sandbox cloud environment where they find everything that they would encounter in industry (data, running code, and other stuff) and are challenged to build and deploy production-grade systems, learning under the mentorship of industry experts. These systems are created using blueprints from leading companies such as Facebook, Airbnb, Pinterest and more, developed in collaboration with the engineers who built them. 'It's like a flight simulator for working environments' 97 million roles in AI & data will be created by 2025. There is no single path to one of those 97 million roles. But, there is a proven path - the AiCore programme. Hundreds of learners commit to the programme to launch their careers every year. You will play a vital role in scaling this to 3000 this year.

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.
