< Agentic First />

A company that keeps running at night.

The Agentic Company Operating System, ACOS for short, gives every department an accountable AI agent. You describe once how a process should run. After that it runs.

  • Procedures, not prompts. In a workshop we write the binding procedure for each department, together with the people who run it today.
  • One managing agent per department. It owns the result and creates the sub-agents that run and check the individual steps.
  • Metrics, not gut feel. Every procedure has an expected outcome and a number that shows whether it was met.
  • Approvals stay with you. You define what an agent decides alone and where a human signs off. Every step is logged.
MARKETING brings leads SALES wins customers OPERATIONS delivers the product FINANCE keeps money flowing Company Manager human

Four departments, four accountable agents, one human who sets the rules.

AI-first Company Code Hive AGENTIC First

We build it on ourselves first.

Code Hive is moving its own operations onto agents, department by department. That is why we know where this gets difficult in practice, not just on a slide.

What we offer you is running in our own business. That is the difference between talking about AI and working with it.

How working with us goes.

Four steps from the first call to running operations. After each one you know the cost and what happens next.

First call

In 30 minutes we learn what your company does, and you learn how we would help. No sales pressure, no cost.

Concept

We analyse the current situation and design the solution. The result is the digital roadmap with scope, architecture and sequence.

Agile build

Your solution takes shape in two-week sprints. You test every increment and can change course before cost accrues.

Go-live and operations

We handle the go-live and take care of updates, maintenance and security. New requests are built in a separate development branch.

What we do differently.

Four points where projects are won or lost. On the left what clients report from earlier projects. On the right how we handle it.

Elsewhere

Complicated billing

Unclear rates, add-on items and retroactive surcharges make projects unpredictable and push budgets up.

The lone freelancer

Holiday, illness or a specialist topic and everything stops. Knowledge sits with one person, the client carries the risk.

A design-only agency

Beautiful screens are not a solution. Without architecture, automation and operational experience you get technical debt and follow-up cost.

Staff leasing

Selling time without owning the outcome creates handover risk and little commitment. Every new booking is a blind date.

Code Hive

Fixed prices, stated upfront

We quote before we build, deliver at the agreed price and invoice once the feature is finished. Whether that is a fixed-scope project, a per-sprint agreement or a monthly support plan.

A team with cover

Our cross-functional team covers strategy, engineering and operations. Every project is documented as it goes, so a handover inside the team is always possible.

Engineers, specialists, owners

We think about the product and the business, put impact before effort, and build systems that earn money, cut cost and scale.

Named people who stay

Named people own the result, communicate openly and deliver. We also tell you when a project does not make sense.

See for yourself.

< Company />

Owner-led, and everyone is a co-owner.

Code Hive is run by managing director Felix Wenz together with the partners as co-owners. Employees can become partners, each with their own responsibility for projects and business areas.

This is not a line for the website. It is the reason nobody here has to wait for an approval from above. Decisions are made where the work happens.

  • Full cost control through fixed prices for projects and support
  • Proactive instead of reactive: monitoring and health checks before something fails
  • No investor pressure, owner-led since the company was founded
  • A usable product in weeks, proven at hackathons
  • AI-first in our own house: our processes run on agents themselves

From Mannheim, along the Frankfurt to Karlsruhe corridor.

Our office sits in the Quadrate in Mannheim. We reach the Rhine-Neckar and Rhine-Main regions in under an hour, for workshops, for equipment in the field and for agile teams on your site. Everything else is remote, across Germany.

Questions clients ask before we start.

What does custom software cost, and how do you arrive at a fixed price?

We name the range once we know scope and goal. That is what the concept phase is for: in one week we produce the digital roadmap with scope, architecture and sequence. On that basis we quote a fixed price per feature or per sprint. You are invoiced when the feature is finished, not for hours spent.

What happens when requirements change during the project?

That is the normal case, which is why we work in two-week sprints. A new requirement is written up as its own feature, gets its own fixed price and is prioritised together with you. You decide what gets built next and see a result after every sprint.

Do we own the source code and can we continue with another supplier?

The transfer of rights of use is settled in the contract. Independently of that, we document every project as we go: concept, technologies used, operations and a quick-start guide. That documentation is part of the delivery and makes a handover possible at any time.

Who looks after us after go-live, and how fast do you react to an outage?

The same people stay responsible after go-live. We monitor the systems, apply updates and get in touch before something becomes critical. Our principle is to find causes and prevent outages rather than earn money from them. Scope is agreed as a monthly support plan or per case.

What is ACOS and how is it different from a chatbot?

ACOS stands for Agentic Company Operating System. A chatbot answers questions, an agent runs a process. In ACOS every department, meaning marketing, sales, operations and finance, gets one accountable managing agent. Together with you we write the standard operating procedures for that department, and the managing agent creates sub-agents that run and control them around the clock.

Is this compliant with data protection law, and where does our data sit?

Before the setup we establish which data an agent actually needs and limit access to that. For the processing we sign a data processing agreement. Models, hosting and tools are chosen according to your requirements, including operation on European infrastructure. Which services are used is written down in the roadmap.

Does an AI agent decide on its own, or does a human approve?

You define that per procedure. Every standard operating procedure states what the agent may do by itself, where a human has to approve and which metric measures the result. Every step is logged so you can retrace what happened.

How do we bring our staff along when agents take over tasks?

The starting point is a workshop with the departments, not with IT alone. The people who run the process today describe how it really works. That becomes the standard procedure. Agents then take over the repetitive steps, while the decisions stay in the house.

Is there still public funding for digitalisation and AI in 2026?

The funding landscape has changed considerably. Several well-known federal programmes have ended, while state programmes and subsidised loans remain, with conditions that differ by region and company size. We check what fits your project in the first call, and we say so plainly when nothing does.

Do you work on site, for example in Heidelberg, Karlsruhe or Frankfurt?

Yes. Our office is in Mannheim and we reach the corridor from Frankfurt to Karlsruhe in under an hour. We work on site where it helps the project, for workshops, for equipment in the field or in agile teams at your premises. The rest is remote, across Germany.

We are hiring.

You have written some code and want to get seriously good at it? We build modern systems and host them in our own Kubernetes cluster. Agile delivery is a given, after work we head to the coding dojo, and to the gym on the way there.

Nothing happens without coffee, we all speak fluent JavaScript, the correct answer to "Star Trek or Star Wars" is of course "Babylon 5", and pineapple on pizza is strictly forbidden. Except for Aaron.
