Tim Leonsteyn · Munich
We use AI to build automations and apps that hold up in daily use.
Two ready-made products, four services made to order, and advisory for growing companies. For freelancers, SMEs, founders and engineering teams.
- Your code and accounts stay yours
- After handover, it runs without us
- Fixed price or day rate, agreed upfront
Products
Two ready-made ways to start.
Both have a fixed scope and a fixed price. You know what you get before you commit.
Your workflow fits neither? Then we automate it individually, inside the tools you already use.

What we take on for you.
Four services, each with a set process and a clear handover.

Almost everything we offer, we run ourselves first. These systems are in use today, one of them at a client.

Advisory
When growth needs structure.
For founders and leadership teams of growing companies we take on engagements in six areas. That experience comes from operational roles in HR, internal IT and interim leadership.
Every engagement starts with a conversation about where you stand, not with a proposal.
- Interim and turnaround management
- Leadership for a set period during transitions, restructuring and growth phases. Most recently interim head of a business unit at microbubbles, 12/2024 to 09/2025, covering team, hiring, processes, budget and reporting.
- Business strategy and structuring
- Strategic planning with a view to organisation and people.
- Organisation building
- Structures that grow with your company instead of breaking at the next step. For example at the Homaris group, while it grew from 7 to 115 employees and from €1 million to €15 million in revenue.
- Leadership strategy
- Develop leadership frameworks, build capable management teams.
- Process optimisation and AI automation
- Simplify the workflow first, then automate it. In that order. For example when a group's accounting was rebuilt around cost centres and DATEV. More on automation
- Project management
- Projects with clear ownership, fixed milestones and honest status reports. For example building a group's internal IT with single sign-on, SCIM and device management.
Who is behind it
One point of contact, from the first call to daily operation.
“I set up every system myself. And if something goes wrong, you write to me, not to a ticketing system.”
Tim Leonsteyn is an operator by background. Today he builds his own software with AI, runs it himself and puts the same tools to work for clients.
