I'm on a mission to revolutionize Europe's construction industry - making it faster, smarter, and more efficient through AI.

At 20, I took the leap into entrepreneurship, starting with event management (our first event drew 1,200 people!), then building a social platform that reached 15,000 users and caught the attention of Shark Tank Switzerland.

But it was construction that captured my imagination. Walking through Zurich and seeing buildings rise from the ground, I knew this industry - with $130B+ TAM - was ready for transformation.

Today at Scalera, we're making that vision reality. Our AI platform has already processed over €8 billion in tender volume, serving 110+ companies across DACH. Backed by Speedinvest and Firstminute Capital ($1.5B+ AUM), and 150+ Unicorn Founders, we've achieved 65% market penetration in Switzerland alone. With a world-class team including former Google and ETH engineers, we're turning a process that takes hours into one that takes seconds.

What drives me? Every building I pass in Zurich might have materials that went through our platform. That's the impact I'm after - not just software in the cloud, but real infrastructure you can see and touch.

Ready to build faster? Let's transform your tendering process together.

→ Connect with me to discuss the future of construction tech
→ Join our team if you're a top engineer ready to build Europe's future

P.S. Still a doer at heart - I believe in taking action over endless planning. Let's build something great together.

For 4 years I worked full-time while studying for my bachelor’s degree on Saturdays. Looking back, it was the most disciplined period of my life.

At that time, InClub wasn’t generating revenue yet.

We had articles written about us, but not much traction. I wanted to use the period productively and develop myself while we were figuring things out.

So I structured my entire life around making it work:

• 5 AM wake-up every morning
• 1 hour of focused study before work
• 45-minute boat commute from Küsnacht to Thalwil
• Full workday until 6-7 PM to catch the last boat home
• Never missed a Saturday class
• Never missed an hour of work

I did this for 2 years straight during our toughest phase, when we were pivoting from InClub, shutting down consulting, and going all-in on Scalera.

The gym was part of the structure too.

In 2023, even with this schedule, I trained six days a week.

At some point, the discipline became a flow. I would wake up automatically at 5 AM. If I didn’t train, it felt wrong.

That consistency also shaped how Scalera operates today.

In our old office, everyone sat in one room.

You could hear the sales team calling all day. You could feel the tension. Everyone was putting the reps in.

That’s the culture we built: act fast, stay disciplined, stay focused.

When I finished my degree in May, I considered doing a master’s. Instead, I decided to go all in on Scalera, and that determination grows stronger. Day. By. Day. 

But I’m grateful for that period.

It showed me that if you structure your days well and stay consistent, things that look impossible become doable.

And that discipline is now part of how we build Scalera.

Making Construction Tendering 10x Faster Through AI | €8B+ Tender Volume Processed | Founder @ Scalera (ETH Spin-off) | Scaling from DACH to Europe

Last week was my first time at Slush, and it ended up being a lot more eventful than I expected. The theme this year was “Welcome to Hel-sinki”. They really leaned into the joke. 

It was my second time in Helsinki, but my first time at Slush, and what surprised me most was how many founders from Switzerland I ran into.

• Jan Schnyder (Nunu .ai)
• Lukas Steiner (Arcium)
• Quirin Hasler (Refluenced)
• Pascal Weber (Manukai)
• Stefan Rau (ChessLine)

It almost felt like a Zurich meetup inside Europe’s biggest investor conference.

For context: Slush is the major investor conference in Europe.

Startups, scale-ups, investors, ecosystem partners - everyone is there. 

You get a startup ticket, scale-up ticket, investor ticket, or ecosystem ticket (think Stripe, Siemens, etc.), and the whole event is organized around back-to-back 1:1 meetings.

And those meeting rooms… it's just endless tables, every one of them booked. I was fully booked for the entire event - back-to-back meetings all day.

A funny moment:

A friend of mine, Lukas, ended up talking to another founder working on a hardware compression startup, and now he’s considering making an investment. What started as a quick chat turned into a real angel conversation.

But the most important takeaway for me was the investor perception of Scalera.

Across two days, I got to speak with almost all the S-tier funds relevant to our space.

And I was invited to the private investor lounges, the two-floor area where only the top funds host meetings - Thanks, again, Northzone, for the first invite. Dominik Esen 

Before Slush even officially kicked off, our investors (First Minute) hosted a joint pre-party called Day 0 with Creandum. That alone was one of my highlights.

And later that day, Kelly Kung at Accel invited me backstage in their tent, which felt a bit like being treated as a rockstar in Helsinki.

Overall, the few days made something clear: Scalera is resonating externally just as strongly as it is internally, and we’re solving a real problem in a market most people underestimate.

And reconnecting with other Swiss founders there reminded me: Switzerland is just the starting point. European construction is where the real opportunity is. And I’m really proud of the ETH ecosystem.

There’s real momentum, real interest, and a market that’s finally ready for the kind of change our team is building toward.

We tested OCR solutions from startups that raised $100M+. Our in-house solution, built as a byproduct, outperformed them all (Kudos to our tech team). Here's what happened:

Scalera needs to extract data from construction tender documents. 

These aren't clean PDFs. 

These documents are messy, inconsistent, and every position can have its own context, unit, and formatting. 

For example, quantities might be in cubic meters, tons, or units, and they can appear anywhere in the document.

So we tested external OCR solutions first, hoping to avoid building this ourselves.

We tried tools from companies like Reducto (backed by a16z, over $100M raised) and Unstract (backed by Lightspeed). 

They handle OCR for sectors like healthcare and finance. We hoped we could simply use them instead of building our own.

But they couldn’t read tender files accurately enough.

The problem isn't technology in general. 

It's the specific complexity of construction documents:

• Context matters → A concrete specification on page 1 affects how you read page 100.
• Quantities appear anywhere → Cubic meters, tons, units, all scattered across varying formats.
• No standardization → Every architect and contractor formats documents differently.

Algorithmically, this is extremely hard.

So our engineering team built the capability internally.

We developed rules for interpreting context across pages, and bounding boxes to reliably locate quantities, even when they appear in different places every time.

It took heavy engineering work, but it now handles the files we work with every day.

What’s interesting is that OCR is the entire product for some of these companies. For us, it’s just something we needed in order to automate tenders properly.

They’re not competitors. In fact, we’d prefer if we could just use their tools.
But since they don’t yet support construction, we can stick to our solution for now.

At Scalera, we have a mannequin in the office named Bob dressed as a construction contractor, and Bob’s job is simple:

To remind everyone that we're building for users, not for ourselves.

When engineers debate features or prioritize the roadmap, I point to Bob. 

"Did you talk to him about this?" 

If not, it's time to schedule customer calls.

It's a humorous approach, but it reinforces one of our core values: talk to users.

That value isn't just a poster on the wall. It's built into how we evaluate every team member at Scalera.

We benchmark employees across multiple dimensions:

• Problem-solving skills
• Communication effectiveness  
• Speed of execution (pragmatic action over endless deliberation)
• Client interactions (how well they understand and respond to customer needs)

If you want to grow here, these values matter. It’s how we evaluate whether someone is truly a Scalerian.
_____

Right now, we're hiring backend engineers.

Technical stack:

• Python (backend)
• React + Next.js (frontend)
• Terraform, OpenAI, GCP across the stack

But technical skills alone aren’t enough.

We want engineers with strong communication skills who are willing to talk to customers, understand their pain, and turn that into product decisions.

That’s why the mannequin stays.

It’s a simple way to reinforce a simple value: Talk to users.

If that sounds like you, we’re hiring in Zurich (or willing to relocate).
