Is your team actually shipping faster with AI?

We turn AI tools into one shared way of working, so your code ships faster, stays maintainable, and survives an audit.

FAQs

What is Harness Institute?

We train engineering teams to work with AI coding tools: Claude Code, Cursor, and Codex.

Harness Institute is the organization behind claudeworkshop.com, cursorworkshop.com, and codexworkshop.com. One team, one framework, three specialist workshops.

What does a training look like?

At least one full day. Most teams pick one or two days. Hands-on, in your own repositories: everyone works, nobody just watches.

Onsite: we come to your office. Offsite: an external venue, out of the daily routine. Remote: live over Zoom. Same trainers, same exercises.

You leave with written rules checked into your repos, review habits for AI-written code, and a plan for the next sprint.

Who is it for?

Engineering teams that already pay for AI coding tools and want the whole team to benefit, not just a few champions. From 5 developers to 100+ engineers, at every experience level.

Regulated industries are our specialty. We work under NDA, inside your environment, and your audit trail holds.

Who are the trainers, and what does it cost?

Rogier and Vasilis, the two founders. Rogier is CTO at BlueMonks Group and runs agents in production every day. Vasilis is partner at Cognitiv+ and helps regulated teams adopt AI. Between them they hold official ambassador roles for Claude, Cursor, Codex, and n8n.

We have free material to get started, and bespoke trainings for engineering teams. Book a discovery call and we confirm scope, dates, and a price.
