No project budget, no hourly rate
You pay for no development and no day rate. You get a finished product at a fixed monthly price — as predictable as any other subscription.
Software Studio · Antoine Massimo I build products,
I build products,
not projects.
You subscribe to the result.
You describe a real, everyday problem. I turn it into a finished software product — and you pay a fixed monthly price for it instead of a project budget or hourly rate.
Typical cases
Sound familiar?
It's rarely the big things. It's the small, repetitive handwork between your programs that eats time every single day.
-
Every Friday you copy the same list from your inventory system into an Excel sheet by hand.
-
Orders come in by e-mail — and someone types them into the system one by one.
-
Your apprentice chases suppliers by phone just to find out the status of an order.
-
Stock runs low — and once again, no one notices in time.
Recognise yourself? That's exactly what I build solutions for — and it won't cost you a cent before it runs.
Services
What you get
You don't just get software, but a solution I take care of entirely — from building it to running it day to day.
You only pay once it runs
I build the solution at my own risk. Only once it genuinely makes your day easier do you start paying — and you can cancel anytime.
The product grows with you
Want something new? I build it in — no project invoice, within the ongoing care your subscription already includes. The product grows with you; operations, maintenance and security are always part of it.
How I work 01 02 03 04
The problem determines the technology. Always.
Every project starts with listening. Only once I truly understand your problem do I decide what to solve it with — the result is software with exactly one job: yours.
Tools follow problems
The choice of technology is a consequence of your requirements. That way, every project gets the solution it deserves: reliable, maintainable and sized exactly right.
Everything from one source
Concept, code and operations from a single pair of hands. From day one you talk to the person building your solution — decisions happen fast, and every agreement lands exactly where it gets implemented.
Built as if for myself
I usually run my solutions myself for years — so I build them to carry that standard: clean, robust and thought through down to the detail.
Honesty as the foundation
You will always get my honest assessment — even when the best solution turns out smaller than expected. That trust is what every good collaboration is built on.
The model
Custom software, without the custom price tag
Most businesses don't need throwaway software for the drawer. They need a tool that grows with them. That's exactly why I build the solution to your problem not as a one-off job, but as a product that's looked after for the long haul and grows with your business.
- 01
Conversation
You describe your problem — I tell you honestly whether I'm the right person for it.
- 02
Concept
I design a solution that solves your problem — conceived as a product, not a one-off job.
- 03
Product
I build the solution as a product in its own right — at my own risk, and so that others with the same problem can use it too. You only pay once you put it to use.
- 04
Operations
You use the solution for a fixed monthly price. I run, maintain and keep improving it.
Projects
My own product
It's here: my own product is live on the Shopify App Store. It shows exactly how I work — I build what the market is missing.
Live on the App Store 
Stockify
Shopify is retiring its own inventory tool “Stocky”, leaving many merchants without a solution. That's the gap I'm filling: Stockify warns small and mid-sized Shopify stores in time, before products sell out. It's now live on the Shopify App Store — and that's exactly how I work: the real problem first, then the product.

About me
One person, full ownership
I'm Antoine Massimo — a software developer from Paderborn, Germany. You work directly with me, from start to finish. That means short paths, clear agreements and someone who truly knows your project from the first call to daily operations. I work in German and English — so I can support internationally minded teams and companies too.
I don't build software to hand it over and disappear — I build products that I run myself and keep improving over years. That same care goes into everything I deliver.
My standard is software that needs no explanation and never gets in the way. It should feel so natural that you eventually forget it's even there.

FAQ
Frequently asked questions
Small and mid-sized businesses with a concrete problem — recurring manual work, data chaos, processes that don't scale. You don't need tech knowledge: you describe the problem, I translate it into a solution.
A predictable monthly price that matches the scope of your solution — with operations, maintenance and ongoing development included. You only start paying once the software runs and actually solves your problem. In a free first conversation you get an honest assessment before anything starts.
Because software isn't finished at handover — that's when it starts living. Instead of one large upfront investment, you pay a predictable monthly price — and get a product that is permanently operated, maintained and improved in return. Maintenance, updates and security are always included.
You can cancel anytime — there's no minimum term. The software runs as a product that I operate — much like Shopify or DATEV, you don't own the code, you use a running solution. But your data is always yours: when you cancel, you get it exported cleanly, and it's deleted afterwards. So you never lose your data — no matter what.
Yes. I take on existing software too: I stabilise and modernise solutions others have built — or tell you honestly when a fresh start is cheaper.
With a short message about what's going on — by e-mail or phone. I'll get back to you promptly with an honest first assessment. No obligation, no sales pressure.
