Custom apps and systems
Custom ERP and CRM systems, WhatsApp AI assistants, sites where you truly own the domain and the SEO. Built around how your business already works — not the other way around.
Live in production today, in our own business
We make AI actually work| in your business.
We build custom software and artificial intelligence. And when what's missing isn't an app but method, we work alongside you as consultants so AI actually works — not just so you can try it out.

What we do
Three ways to work together
🧭
IT advisory and consulting
Not every business needs an app on day one. Sometimes what's missing is a diagnosis, structure, and a clear method to use AI well — that's a service too, and we offer it on its own.
🧠
Memory that doesn't reset
We document your business's knowledge so every conversation with the AI picks up where the last one left off, instead of starting from zero each time.
Coming soon: digital ads, social media management, and email automation for businesses that already have the basics in place. If that's you, tell us and we'll figure it out together.
Where we fit
We're not the only option — we're the right fit for a specific moment
If you're a corporation with a seven-figure budget, hire a global firm. If you already know exactly what to build, a freelancer will do. We're for the small or mid-sized business that wants a real, working case in a few weeks — with judgment and hands-on support.
| Big firm | Freelancer | ListoApp | |
|---|---|---|---|
| First result | Months of discovery | Fast, if you know what to ask for | Weeks, with a tight scope |
| Who you work with | A team that rotates | One person, no backup | The same people, start to finish |
| If you don't know what you need | They sell you the big project | They build whatever you ask for | We tell you before we charge you |
| Who owns the system | Their platform, their license | Depends on the deal | Yours: domain, data, and code |
| Proven first on | Other clients' cases | Their portfolio | Our own business |

Your data
Data privacy, handled responsibly
✓
We only collect the customer data your assistant or system actually needs to do its job — nothing more.
✓
You can request access to, correction of, or deletion of your data at any time — just ask.
✓
Your business's information is never used to train third-party AI models: the knowledge base is yours, and it lives on your own infrastructure.
✓
We build with responsible-AI principles in mind: transparency, fairness, and no discrimination.
