01The shift
Everything your team does today, without the wasted hours.
Without systems

- Disconnected tools that don't talk to each other
- Growing means hiring more
With AI systems
- Data moves on its own, without errors
- Instant replies, 24/7, in your tone
- Reports ready when you arrive in the morning
- Everything connected: CRM, email, ERP and documents
- Your team focuses on what adds value
02Services
What I build for your business.
Every project starts with a specific process that costs you time or money today. No pretty demos: systems that are used every day.

Custom AI agents
Agents that serve customers, qualify leads or answer your team using your company's information, and escalate to a person when needed.

- sales
- internal support

Process automation
Invoices, orders, customer onboarding, reports, repetitive emails. What's done by hand today runs on its own, with control and alerts.

05About
I'm Rankgnar. I build AI systems.
- AI in my daily work
- My own servers and infrastructure
- Sites, apps and agents in production
- Direct contact, no agency
I design and build AI systems, automations and software for businesses. I don't sell templates or hype: I build tools that are used every day.
Everything I offer, I use first in my own projects. My applications run on my servers, with my agents and automations. This very website was designed and built with AI.
I work with a few companies at a time so I can be truly involved in every project.

07FAQ
Frequently asked questions.
What kind of businesses can benefit?
Any business with repetitive tasks, lots of customer communication or information spread across several tools: professional services, retail, distribution, clinics, real estate, agencies… If your team loses hours on mechanical tasks, there's room to improve.
How much does a project cost?
It depends on the scope, which is why the first step is a free assessment. Then you get a proposal with a fixed price per phase, so you can start with what pays off most.
How long does it take?
A specific automation can be running in days; a more complete system, in a few weeks. I work in phases so you see results from the first delivery.
What about the privacy of my data?
It's designed in from the start: we only process the data we need, under confidentiality agreements and, if you prefer, everything on your own servers in Europe. GDPR compliance is part of the project.
Does my team need to be technical?
No. Systems plug into the tools you already use and your team is trained to use them. If something fails, the system alerts you.
Which AI tools do you use?
Whatever fits each case best: models from Anthropic (Claude), OpenAI or Google, and also models that can run on your own servers. I don't depend on a single platform.
What if I want to change something later?
The code is yours and documented. You can stay with me on monthly support, extend the system in phases or hand it to another team.
