Enrol on UdemyMost AI courses teach you to prompt. These teach you to build the thing that runs afterwards, because that is where every project I have seen actually fails. The n8n and agentic AI material comes out of deploying 55+ production agents across 10 business functions. The infrastructure and firewall courses come out of 25 years of running the systems underneath.
If you would rather read first, the insights library covers the same ground in essay form, including building your first n8n agent, agent security and what agents actually cost to run.
Corporate training runs as half-day workshops, multi-day programmes, or an ongoing cadence, built around your processes rather than a generic curriculum. Executive coaching available for CTOs, CIOs and senior teams adopting AI at scale.
