Turn your idea into a real product.

Most founders don’t fail because the idea is bad.
They fail because they never start or they build the wrong thing first.
I’ll help you validate fast and ship an MVP in days, not months.

Real product, real users — we build and ship fast.

Sound familiar?

You've been sitting on an idea for months, maybe years.

You're overwhelmed by "where do I begin?".

You're not technical, so building an MVP feels impossible.

You are now asking yourself what the hell is an MVP?

You're tired of theory. You want to start doing.

You don't need more learning. You need a real, tested path:
Idea → Validation → MVP. That's what LaunchLab gives you.

You’re excited… but unsure

Most founders have energy and ideas, but no clear path. We turn that excitement into a concrete plan you can execute.

Stop building the wrong thing

No logos, no busywork. We validate with real people and real signals before you spend weeks building.

Niche → problem → offer

We help you narrow the niche, pick a painful problem, and craft a first offer you can sell.

I've built multiple products. Some failed. Some took off. All of them taught me what actually works.

Here's what I learned:
Most people don't fail because their idea is bad.
They fail because they never start or they start the wrong way.

LaunchLab exists to fix that: validate fast, build with AI, launch, iterate.

If you're ready to finally turn the idea in your head into something real, LaunchLab is for you.

FAQ

I'm not technical. Can I really build something?

Yes. I teach you to build using AI agents and no-code tools. If you can describe it, you can build it.

What if I don’t live in Sibiu?

No problem. LaunchLab Online is global (video calls). The Weekend is the in‑person version in Sibiu. If you want the Weekend experience but can’t travel, we can still run the exact same method online.

I’m excited about my idea… but I’m not sure it’s the right one. What do we do?

We don’t start with “build”. We start with niche → problem → offer. We’ll generate options, score them, then pick one to validate. The goal is to leave you with something you can actually sell.

How do I validate without wasting weeks (or money)?

You’ll run a tight validation loop: quick research, a simple landing page or message, and real conversations. Validation is not “my friends said it’s cool” — it’s getting the first people willing to pay or commit.

What if I’m not technical?

That’s normal. We’ll use modern AI tools to build an MVP without a big dev team. You don’t need to become an engineer — you need to be able to decide what to build and ship the next version.

What if I already tried a business and it didn’t work?

Perfect. You’re not starting from zero — you’ve learned what not to do. LaunchLab is built to remove the classic traps: endless planning, premature branding, and building before demand.

How is LaunchLab different?

I'm an operator, not a theory coach. I build real products like PredictApp.

How long until I see results?

Most founders get a validated idea in 1 week and an MVP in 4–6 weeks.

What happens at the LaunchLab Weekend?

Friday → Validate.
Saturday → Build with AI.
Sunday → Polish & launch plan.

Stop Waiting. Start Building.
