The problem
Small changes
shouldn't be this hard.
A simple update can turn into days of chasing code, checking things by hand and worrying about what might break. We tackle those recurring problems so the next update is easier to make.
What to watch for
Where Work
Gets Stuck.
When these things happen often, your team spends more time working around the software than improving it.
Features Take Too Long
A small request means changing several systems, so it takes longer and longer to finish.
Releases Feel Risky
Each launch needs lots of manual checks, or regularly break things, affecting your customers.
Workarounds Pile Up
People repeat fixes or avoid touching fragile areas because of fear. Your business can't react to market realities.

Agentic coding
Make Your Code
Ready for AI Agents.
Coding agents are more useful when they can run the project, understand the code and test their changes. We clean up hard-to-change areas, document how the project works and add reliable tests. That helps your engineers use agents on more development work and check the results.
How we work
Start where
it hurts most.
We start with something your team deals with every week: a slow release, an integration that often breaks or code nobody wants to touch. We improve that part, check whether it saves time or reduces risk, and decide what to tackle next.

Fido case study
Fido replaced its tools
one by one.
Fido used Monday.com, WooCommerce and spreadsheets to run its trash-valet service, but the tools didn't talk to each other. We moved operations and billing into a new system one piece at a time while the business kept running. Customers can now sign themselves up, and the system keeps data in sync.

Perk rebuilt its site
without starting over.
Perk wanted a faster website without throwing away its Storyblok content or existing infrastructure. We moved the site from Next.js to Astro, updating 205 content components across 29 page templates and nine locales. The new site went live 13 weeks after the first commit.

Say About the Work.
From taking over an existing platform to digitizing manual work, these clients describe what it was like to work with us.
Testimonials
Makers' Den delivered a self-managing team who created our new website to serve as the marketing spearhead for our online campaigns. What really struck me positively is that we could directly talk to the production team and get changes implemented on the turn of a dime without going through extra account managers.

What to keep
Not everything
needs rebuilding.
Sometimes a few careful fixes are enough. Sometimes one part needs replacing. We help you decide what to keep, what to improve and what to rebuild, then plan the work so customers can keep using your product.

Software Modernization FAQs
Before you
rebuild anything.
Can we modernize our software without rebuilding it from scratch?
Yes. We look at what is slowing your team down or causing problems, then improve or replace those parts. We keep the parts that still work and plan changes so customers can continue using the service.
Can you replace old systems one at a time while the business keeps running?
Yes. For Fido, we replaced a mix of Monday.com, WooCommerce and spreadsheets piece by piece while the trash-valet service kept running. The new system brought operations and billing together and automated customer sign-up.
How do you decide what to modernize first?
We start with a problem your team deals with regularly, such as slow releases, repeated manual work or an integration that keeps breaking. We agree on a first improvement, see what it changes and use that experience to plan the next step.
Can you make our codebase easier to work on with AI coding agents?
Yes. Coding agents are more useful when they can run the project, understand how it works and test their changes. We improve setup instructions, tests and hard-to-change code so your engineers can use agents on more development work and review the results.
Can we keep shipping new features during a modernization project?
Often, yes. We plan the work around the software and release process you already have, so improvements can be introduced in stages. We will discuss any areas where a change needs extra care before work begins.
I want to keep my idea confidential. Will you sign an NDA with me?
Yes, we sign an NDA (Non-Disclosure Agreement) always when a client wants it. We can do it at the very beginning before we discuss your project's details, or at another stage of the process - it's up to you.
Do I own the intellectual property rights of my application?
Yes, you are the owner of Intellectual Property rights at all times.
Where is your development team located?
We are fully remote. So while we were founded and are still based in Berlin, most developers will be remote from a central European location.
What is the pricing model?
You work with us on a Time & Materials basis. The total cost depends on the actual time the team spends on the development. You are in charge of the project’s scope and set priorities for the development team.
Time & Materials allows flexibility for you to set the direction of development depending on the users’ feedback, market situation, or opportunities that arise during the development.
For more about how we create estimates read how to estimate software projects .
What would my development team look like?
We adjust the team depending on your needs. Our speciality is low overhead teams, where every member is contributing concretely towards customer facing features. That means everyone is either doing development or design.
Roles like Project Manager, Business Analyst and QA are responsibilities which are shouldered by our business oriented developers or designers.
You may take the role of a Product Owner, making decisions on priority and scope.
Can you work as an amendment to our in-house team?
Yes. We can adapt to your tools and processes. I.e. fully integrate into your existing team.
How does the company ensure code quality and maintainability?
We follow best practices, perform code reviews, implement automated testing and continuous integration to ensure code quality and maintainability. All projects are not equal though and the level of automated QA will be determined on your need for quick feedback from the market.
Can you hand the code over to another team?
Yes. We create easily understandable and maintainable code using well known frameworks which don’t require niche knowledge.
The runtime environments we can set up in your ownership from the get-go.
What is the experience level of my team?
Every team has a partner involved in the project. Our developers have a proven track record of outsized throughput. Our culture is one of delivering features every day. That's why we prefer senior developers, but not seniors that are from slow moving enterprise environments.
How am I kept up-to-date of development?
We have fixed length iterations (usually 1 week), at the end of which you will be demoed the current progress. You will have access to team members through Slack, email and video calls and our regular meetings. In addition to this you will have access to our project management tools (Jira or Asana), which we update daily.
Why hire us?
We love what we do and only employ people with a similar mindset. You ship faster by working with a small team where each developer is a focused on your business goals. With us you get direct access to everyone. This keeps overhead low and output high.
You are in control. We offer full transparency of progress and potential problems. We keep you informed and present options, but you make the decisions.
We value our client relationships and their product visions. Meet with us to see if we share the same conviction. We might be a good fit.
