From idea to SaaS

Build beautiful
AI software.

Learn the exact process I use to turn ideas into real products, from finding the right idea to your first paying customers. A step-by-step system for non-technical founders.

I don't teach theory.

These are the products I've actually built. Everything I share comes from making them.

Most of us own more clothes than we think, and still feel like we have nothing to wear.

minniie turns your real closet into outfits. Upload your pieces, import Pinterest inspiration, analyze your color palette, generate outfit collages. I built the first MVP in one weekend with Lovable, then shaped it into a polished product with my own UI kit and branding.

MoodBoardAI — AI interior design

MoodBoardAI

AI interior design

It's hard to imagine how your room could look before you commit to changing it.

Part of the MoodBoardAI project, MyRoomDesigner AI lets people apply different interior styles to their own spaces through AI-generated visualizations. Co-founded with Gabor. It's my longest-running product, and where I learned most of what I know about iteration.

Skincare, simplified

Keeping a skincare routine consistent is harder than starting one.

A solo SaaS project I build end-to-end: product strategy, UX, development and deployment. It's my training ground: the place where I debug systematically, iterate on real user needs, and practice everything I teach.

AI can generate components for free. Knowing which ones convert is the hard part.

My UI kit, articles and advisory work, built from real product decisions, including a redesign that doubled a SaaS product's revenue without changing the code. Everything here runs on the same process I teach.

My story

I didn't come from software engineering.

I started as an interior designer. Spaces, light, how a room makes you feel.

In 2017 that work turned into my first digital product, an online interior design service. Software followed in 2020, when my husband and I created what later became MyRoomDesigner.ai. That first SaaS was the start, and somewhere along the way I fell in love with building products.

Back then I wasn't the one writing the code. I shaped the product and carried everything around it: marketing, sales, documentation, testing, finding customers, link building. It was a full education in everything a product needs beyond the code itself. Eventually I wanted the last piece too, so I started learning to code. Then AI tools arrived, and something shifted. The products I had been imagining for years were suddenly within reach.

Since then I've been building SaaS products from first idea to paying customers: designing them, shipping them, finding the people who need them, improving with every launch, and documenting all of it as I go. I built the first MVP of minniie in one weekend. It wasn't perfect, but it was real. A few weeks later, a stranger paid for it.

Now I want to share that process with other founders who don't come from code. Not because I have all the answers, but because I know exactly what it feels like to have the idea and not the roadmap.

What you'll learn

Idea to first customers, step by step.

The same path I follow with every product. Open a step to see what's inside.

  1. Where good ideas actually come from: usually a problem you have yourself. minniie started that way.

    How to recognize which ideas deserve months of your life, and which ones to let go.

    Research competitors without getting discouraged by them.

    Define positioning so you know why your product should exist.

  2. Simple ways to test demand before writing anything.

    What I look for in search data, communities and competitor reviews.

    Talking to the people you want to build for.

    When a lukewarm response means "adjust" and when it means "walk away".

  3. How to define your MVP and draw the line on scope.

    Prioritizing features when everything feels important.

    Avoiding functionality nobody asked for.

    Planning a product you can actually finish.

  4. Designing intuitive user experiences, even without a design background.

    Creating premium interfaces people enjoy using.

    The small design decisions that make software feel considered.

    Why calm, clear UI builds trust, and how that shows up in revenue.

  5. How I use modern AI tools to build real SaaS products.

    Workflows that dramatically speed up development.

    How I moved from a weekend Lovable MVP to a polished product.

    Working with AI daily without losing control of your codebase.

  6. Landing pages that explain your product clearly.

    Pricing and payments, without overthinking it.

    Analytics, so you can see what is actually happening.

    Launch preparation and publishing your product.

  7. SEO: the process that brought my first minniie subscriber.

    LLM visibility: showing up when people ask AI tools for recommendations.

    Content and building in public.

    Earning trust instead of buying attention.

  8. How to improve your product using real customer feedback.

    Knowing what to build next, and what to skip.

    Avoiding feature overload.

    Small consistent improvements, every launch a bit better than the last.

How I think about products

Beautiful software matters.

People decide whether they trust your product in seconds. Design is not decoration. It's the first conversation you have with a customer.

The best products solve one problem exceptionally well.

Every product I've built got better when I removed things, not when I added them.

Shipping beats perfection.

minniie's first MVP was built in a weekend. It wasn't perfect. It was real, and real things can improve.

AI should amplify your thinking, not replace it.

The tools are powerful, but the judgment about what to build, what to skip and what feels right still has to be yours.

Good design creates trust.

I once doubled a product's revenue by redesigning the interface. Same code, same users. Calmer design.

Small consistent improvements compound.

Every launch teaches something. The goal isn't a perfect product. It's a better one than last time.
