Amodo is a hardware engineering company building the 21st century's most important technologies. Our team of mechanical, electronic, firmware, and software engineers are trusted by world-leading startups, universities, governments and philanthropists to solve pressing technical challenges. See who they are on amododesign.com - including MIT, Cambridge, Oxford, Imperial, ARIA and Rand Corp. We are selective in the projects we take on and proactive in seeking out where our exceptional engineering teams can make the most impact. We believe in differential technology development: deliberately accelerating safety-enhancing technologies to ensure human flourishing. Not every technology is inevitable – rather, the market fails to incentivise key domains. We work in these areas. We’re currently focused on four key fields: AI safety, biosecurity, humane tech, and accelerating science (developing the hardware tools that scientific breakthroughs require, but don't yet exist). In addition to client work, we want to bring our inventions into the world as spin-out companies, open-source projects, and products. We're actively hiring people to take charge of making this happen. We’ve doubled year on year since our founding in 2023, and we aim to do so again in 2026. That means we're actively hiring across electronics, FPGA, mechanical, firmware, software, physics, HPC infrastructure, and DevOps - plus exceptional talent in any discipline.

We're solving the wrong problem. Everyone's trying to teach small business owners to be better marketers. Better social media strategies. Better content calendars. Better posting schedules. But here's the thing: A therapist shouldn't have to be a social media expert. A wedding planner shouldn't spend 6 hours a week posting content. A wellness coach shouldn't hate their own marketing. The problem isn't that they're bad at marketing. The problem is that they're doing marketing at all. At Omada, we believe the best marketing is invisible marketing. Omada means "team" in Greek. Not a tool. Not a list. A team. We've built the first AI marketing team specifically for service businesses - a "do it for me" team that creates, executes, optimizes, and supports while you focus on what you do best: serving clients. For small business owners, it means you're never alone. While you build your business, your AI marketing team is already at work. Thousands of companies are already waiting for this future. Technology should do what technology does best, so humans can focus on what humans do best. That's not optimization. That's revolution. Omada. Your team, in motion.
