Our real "price": the prototype comes free with your project.
The build is a fixed quote, set after you've seen it. If we don't scope it right, it's on us.

Greenstone is for you, if…

01

The consultants left a 60-page AI strategy. Nothing runs.

Roadmaps, workshops, maturity assessments, and still no process runs differently on Monday. We skip the deck: pick one expensive process, and within 1 to 3 weeks you’re clicking through it running automated.

02

Your margins can’t carry these labor costs forever

Re-typing, sorting, checking, chasing: work that grows with every new customer. Automation lets capacity scale without new hires, so margins grow with revenue instead of shrinking with payroll.

03

Everything you’ve seen is either a toy or a science project

Chatbots that answer FAQs aren’t transformation. Orchestrated agents that hand work to each other across a whole workflow, from intake to invoice, are. That’s what we build, and what we run ourselves.

04

The board asks about your AI strategy. You don’t have one.

You don’t need a strategy deck to answer the board. You need one process running automated, with the payback numbers next to it. That’s the first thing we build.

Who this is NOT for:

Companies under ~€1M annual revenue, chatbot-toy shopping, and projects where nobody owns the process being automated. We automate real operations for companies where the payback math has to work.

What do you get?

Everything between “we should do something with AI” and “it runs in production”, all from one partner.

01 / DE-RISK

Name your most expensive manual process. Our analysts map it, and within 1 to 3 weeks you’re clicking through the automation running on your actual workflow, before you’ve signed anything long-term.

Judge a running system, not a vision.

02 / SUBSTANCE

We rank your processes by payback and tell you which ones don’t deserve automation. Where AI doesn’t pay, we say so and don’t build it. That’s why hype-burned CEOs trust the third recommendation.

We talked a client out of two ideas. He hired us for the third.

03 / COVERAGE

Systems of agents that hand off to each other across a workflow, ten and more working in concert. Automation that changes the cost base, not a widget. Integrated into your existing systems, A to Z.

Intake to invoice, automated end to end.

Why we can move this fast (and keep it affordable):

We run our own delivery on the latest AI models and automation: research, analysis, prototyping and engineering, accelerated end to end. That means faster builds and lower cost for you. And the same AI and automation expertise gets built into your product, optimizing your processes and operating costs from day one.

How do we compare to an AI consultancy?

Eight parameters that decide whether your build ships right the first time.

The short version:

An AI strategy engagement costs about the same as a working automation of your most expensive process. After 90 days, one of them is still a PDF. The question isn’t “who knows AI”, it’s “what’s actually running in my company after the invoice”.

Who you’ll actually
be talking to.

Not an account manager. Not a sales team. The two people who own the company, on every deal, from first call to launch, together with our project managers.

Frequently asked questions

No. There is no pilot phase. The prototype runs on your actual process before any long-term contract, and the build that follows goes to production. Pilot purgatory is a consultancy business model, not ours.

Yes, in writing. Recommendations are payback-gated: where automation doesn’t return, we say so and don’t build it. We’ve talked clients out of their own ideas. It’s why they trusted the ones we did build.

No. Most clients automate the work nobody wants (re-typing, sorting, chasing) and redeploy people to work that grows revenue. The payback comes from capacity scaling without new hires, not from layoffs based on a demo.

The analysis and prototype come free with the project. You pay a deposit, agreed after our first qualification meeting; if you continue, we credit 100% of it toward the build, and if you don’t, the prototype is yours to keep. Production automation is scoped fixed after the prototype, typically from the tens of thousands of euros, sized against the payback math on the table.

Central European engineers are among the most sought-after in the world, and we run our own operations on the same AI infrastructure we sell. EU contracts, English-speaking owners on every call.

Every automated process reveals the next one. Most clients scale process by process into an orchestrated agent infrastructure, with maintenance and further phases under a long-term partnership.
