One week in, they’d already shipped.

Sustainability professionals from our first cohort, in their own words.

What you'll build

You don't need to code. You need to become the architect.

AI gave everyone the same tools. It did not give everyone your expertise. In six weeks you'll turn that knowledge into working tools, with no developer and no expensive software.

Who's teaching

A practitioner, not a guru.

"Not the smartest in the room when it comes to AI. Not the deepest expert in sustainability either. But I'm curious. I test things. I apply. And I share what actually works."

— Zyad Hatquai · Chemical engineer & sustainability manager who learned AI by applying it to his own real work first.

How it works

Twice a week. Build, don't just watch.

Monday · Session 1

60 min · Build Together

I walk through the workflow live — not slides, actual work. You follow along on your own machine, building the same tool in real time. Your laptop must be open and ready. This is not a webinar.

Friday · Session 2

90 min · Show & Share

3–4 participants share what they built, why they built it, and what they'd do differently. Peer feedback, troubleshooting, iteration. This is where real learning sticks.

6 weeks · 2 sessions per week · ~15 hours live together + ~15 hours building on your own · Total commitment: ~30 hours · Time zone scheduling confirmed with accepted participants · Approx. 16:00–18:00 CET
The foundation underneath: the course, the material, and every recording live in the community. Something breaks mid-week? You get a response in under 24 hours.
What you leave with

Not a certificate. Your own operating system.

6+ Deliverables

Real tools you built yourself that you'll take straight to work, plus the reusable skills I provide so you can build high-quality tools every time.

Multi-Tool Fluency

Claude Code, Netlify, Supabase, Resend, Anthropic API: a full stack that lets you build real, working tools, not toy demos.

Real Career Signal

A portfolio of AI-built sustainability tools to show your boss, your next employer, or your clients. Starting Monday.

SustainOS Workflow

This isn’t about tools built during the cohort. It’s the repeatable workflow behind it. You leave as the architect, who can build any tool any time.

Why now

The field is shifting. Early movers win.

+90%
of 1,000+ sustainability professionals say AI will change how the work gets done.

I asked over 1,000 sustainability professionals about the future of their work. Over 90% told me the same thing: AI will change how the work gets done. Almost none of them knew how to act on it.

That gap is the opportunity. In every shift like this, the winners aren't the most qualified. They're the earliest. The people who start building while everyone else is still waiting to see what happens.

If you're on this page, you already feel the size of what's coming. The only question is whether you move on it now, while being early still counts, or later, when it's just catching up.

Cohort 2 · Registration open

Cohort 1 is full. Cohort 2 registration is open.

Registration for Cohort 2 (starting 10 August) is open now, with no waiting list. But this isn't first-come, first-served. We keep every cohort small and personally vetted, so joining is a short, selective process designed to make sure it's the right call for both of us.

3 minutes, max

Fill in the application

A short form about your work and what you'd want to build. No payment, no commitment yet.

In the coming weeks

Book a fit call

If it looks promising, we talk. A two-way conversation about your goals and whether this is the right move for you.

Limited seats

Enroll & start building

Confirm your spot and join the cohort. The room stays small, serious, and committed.

Show up and build every week — 30 hours over 6 weeks. Live sessions are where the learning happens.
Share honest feedback throughout — you're not just a participant, you're helping shape the curriculum.
Make at least one tool you build publicly available — your work is proof this works.
Bring at least 2 years of sustainability experience — you need to know what the actual work looks like.
€2,000
The investment for Cohort 2. You don't leave with notes. You leave with tools that do the work, again and again.

Takes ~3 minutes · No payment at this stage · We review every application personally.

Every participant is personally vetted. This isn't just a course, it's a community you're joining.

Common questions

Before you apply.

Do I need coding experience?

No. You need to know your job. AI tools handle the technical complexity. If you can describe what you need, you can build it. I didn't consider myself a coder when I started — I still don't.

What's the time commitment?

About 30 hours over 6 weeks. ~15 hours of live sessions (Monday builds + Friday demos) and ~15 hours of exploring and building on your own. Intensive, but designed around a full-time role.

Will I work with my own data?

We work on real use case types drawn from actual sustainability work — while keeping your data exactly where it belongs. The goal isn't automation for its own sake. It's transforming high-effort work into low-effort work without compromising data privacy.

What if I miss a session?

As a founding member, I expect full commitment — please treat this as non-negotiable. Monday build sessions are recorded. But the Friday demos are where real learning happens. Plan to attend every one.

Why €2,000?

The programme runs 6 weeks with 2 live sessions per week, personal feedback on every build, and direct access throughout. You leave with 10+ real deliverables built on your actual job and lifetime access to the SustainOS community. The investment reflects the time, depth, and outcome — not a content library you never open.

Where can I learn in the meantime?

The SustainOS newsletter and YouTube channel are both free and updated regularly. Both cover AI tools for sustainability work, real builds, and the same practitioner-first approach you'll find in the cohort. Subscribe at newsletter.sustainos.io or watch at youtube.com/@ZyadHatquai.
