Unlock AI's potential for your business

I build AI that solves your company’s problems and fits into the processes you use today. The goal is to free up time so your team can focus on what they do best.

I'm Johannes. My 15 years of experience in AI help me build and test solutions that reduce repetitive work and free up time for what matters most.

Let's talkCustomer Story: Sicotronic Sverige AB

Customer Story

A custom agent for offer generation.

“When a new project request comes in, it helps me respond quickly and accurately.”

Fredrik Björklund, CEO of Sicotronic Sverige AB

Sicotronic Sverige AB provides control systems for commercial kitchens that reduce peak current demand and ease pressure on the electrical grid. Each new project request meant Fredrik working through files and drawings, researching equipment and preparing the proposal.

Now Fredrik forwards the request to the agent. It prepares the calculations and proposal while he reviews the technical decisions. This saves hours, removes repetitive paperwork, and preserves the company’s knowledge.

Where AI can help: Fixing the work that gets stuck

Case Study

Newsletters without the repetitive prep.

For a large Swedish education company, newsletters help sell courses. Preparing them meant the same time-consuming work, over and over.

The marketing team tells their custom agent what they want to promote. It gathers course details and images, writes in their tone of voice and puts the newsletter together in Brevo, including suggested recipient lists. They come back to a draft they can refine and send. Sending stays with the team.

Case Study

The business runs on a spreadsheet. Keep it moving.

A lot of companies run on Excel or Google Sheets. They manage sales, contractors and projects in Excel, but email updates and follow-ups can slip through the gaps.

The spreadsheet now takes an active role: ChatGPT picks up relevant messages and updates the records, while regular checks flag stale items and prompt follow-ups. The team keeps the system it knows, with AI built around its processes.

Case Study

ChatGPT connectors for the tools you already use.

Your company is adopting AI, but progress stops when you reach legacy software or systems that aren’t ready to connect. It’s a common problem.

I build secure, custom connectors using MCP, the Model Context Protocol, to connect ChatGPT or the AI tools you already use with your existing software. We define what the connector can access and change, so it fits your processes and permissions.
