Direct collaboration

Work Directly
With the Makers.

Talk with the engineers building your product. They'll understand the problem, help decide what to build next and stay involved through release.

Where we help

Start Where You Are.
Build What's Next.

Whether you have an idea, a prototype or a product people already use, we help you work out what matters, get it live and keep making it better.

Discovery & Design

Discovery & Design

Depending on where you are, we can execute discovery for you, with an initial thesis and UX of the product; together with an estimate for implementation.

Prototype to Launch

Prototype to Launch

We use AI agents to explore designs and build a working prototype quickly. Then we test it with users, refine what needs work and get it ready to launch.

Continue Improving

Continue Improving

We keep shipping after launch, fixing what slows people down and adding the improvements customers actually need.

Across the product

What Users See.
What Makes It Work.

We build web and mobile experiences, backend services and the integrations that connect them. We can add AI features where they solve a real problem, and work alongside the specialists you already have.

Testimonials

Testimonial Illustration

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.

Product Engineering FAQs

What to know
before we build.

Can you build an MVP and continue improving it after launch?

Yes. We can build a first version for real users, then improve it based on what they do and tell you. That means the product can start delivering value before every idea has been built.

Can you take a prototype into production?

Yes. A prototype can show that an idea works, but it may still need reliable integrations, testing and a way to run it day to day. We identify what is missing and build the parts needed for customers to use it.

Can you improve an existing digital product instead of building a new one?

Yes. We can work on a feature, customer journey or the systems behind it. We fit the work into your existing product and collaborate with the people already responsible for it.

Do you build web and mobile apps as well as backend services?

Yes. We work across web and mobile experiences, backend services and integrations. That lets us connect what customers see with the systems that make the product work.

How do AI agents help you design and build products?

We use AI agents to explore design options, build prototypes, implement features and run tests. This helps us get working software in front of you sooner and respond to feedback quickly. Senior engineers choose the approach, review the work and remain responsible for what ships.

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.
