Digital Challenges

Five situations from hundreds of initial consultations, typical for companies and public authorities of any size.

1
The limits of standard software

Off-the-shelf products are built for the masses, not for an organisation's own workflows. The result: isolated solutions and duplicate data maintenance.

2
Inefficient data management

Spreadsheets grow with the organisation, their structure does not. Reports take time, and nobody knows which number is correct.

3
Security risks in the supply chain

Almost one in three successful cyberattacks comes through the supply chain. That is why NIS-2 demands proof of security from every service provider working on critical software.

4
Unstable in-house developments

The homegrown solution somehow works. Without documentation and tests, however, every change becomes an avoidable risk.

5
Digital sovereignty

Standard platforms tie data and processes to third-party vendors. Licence models change, features disappear.

Team assembling a software project like puzzle pieces: illustration for custom software development

Five challenges, one answer.

Starting from the concrete use case, step by step software takes shape that fits the organisation's own workflows. It all begins with a no-obligation conversation with our development experts in Berlin.

What TenMedia Develops

Custom Software & Apps

Desktop, web and mobile (iOS and Android), ERP, CRM and industry software. Built precisely around the client's workflows.

AI Integration

Privacy-compliant LLMs for organisations, automation of recurring processes and processing of unstructured data.

Databases & Migration

Structured data management instead of spreadsheets: sensibly modelled, managed as needed, protected against loss. Existing data is migrated without loss.

APIs & System Integration

Interfaces, middleware and permission management so that systems talk to each other instead of data being maintained twice.

Legacy Modernisation

Further development and step-by-step replacement without interrupting operations, including takeover and stabilisation of existing in-house developments.

UX/UI Design & Accessibility

Intuitive interfaces built to WCAG and BITV 2.0. A legal obligation for public authorities; companies avoid liability risks and reach more users.

Custom Software Solutions for Companies and Public Authorities

Custom software maps workflows the way they actually happen, so the software supports everyday work and not the other way around. What that means in concrete terms differs from organisation to organisation.

Public Sector & Critical Infrastructure

Specialist procedures, administrative software and portals for public authorities, municipalities and operators of critical infrastructure. Built for long service lives and documented transparently.

Small and Medium-Sized Enterprises

Dedicated contact persons, a fixed price based on requirements and software that grows with the business. Quickly operational as a minimum viable product (MVP), then expanded iteratively. The investment pays off through saved working time instead of ongoing licence fees.

Enterprise & Corporations

Scalable architectures, APIs and integration into existing system landscapes. Custom software as a competitive advantage: mapping processes no competitor can buy off the shelf.

Honest Software Development

Six promises TenMedia can be measured against before, during and after the project.

If TenMedia misjudges the schedule of a new development without the requirements having changed, TenMedia covers the difference, not the client.

TenMedia does not take on any project unless the team is convinced it can deliver it successfully, and says so openly before a contract is signed.

Unencrypted source code can be inspected from the start of development. Comprehensive usage rights transfer with the final payment.

Modular development following programming standards, fully documented. The software remains maintainable and extensible for years, by TenMedia, the in-house team or any other agency.

Development with licence-free open-source frameworks such as Laravel, .NET and React instead of WordPress or Joomla. Security by design included.

A permanent team in Berlin, no outsourcing. Dedicated contact persons from the first conversation to go-live.

How We Work

From idea to ready-to-use software in five steps. Transparent, iterative and with full control over budget, timeline and scope.

Getting to Know Each Other & Offer

Non-binding and free of charge. TenMedia responds to enquiries within one working day. After the requirements analysis, a written fixed-price offer follows: the price is based on the agreed scope, not on the actual effort.

Initial software development consultation: two people talking at a table with a laptop

Kick-off & Concept

Goals, priorities and schedule are fixed before development begins. The result is a roadmap and a technical concept.

TenMedia takes care of

Technical conception, planning, milestones and the shared working environment.

The client contributes

The business vision, documents, system access and a named contact person.

The Scrum principle: prioritised backlog, sprint of two to four weeks with planning, design, development, testing and review, followed by a usable result on the test server

Iterative Implementation

Short cycles instead of flying blind until acceptance. After every sprint of two to four weeks, a usable result is live on the test server.

TenMedia takes care of

Design, development, testing as well as quality and risk management.

The client contributes

Approving milestones, providing feedback.

Acceptance & Go-live

The software is transferred to the production environment, installed and configured, either in Microsoft Azure or on-premises. Including introductory training on the real application.

TenMedia takes care of

Stabilisation, introductory training.

The client contributes

Business-side steering, final acceptance.

Go-live: software is securely transferred from the development environment to the production server

Long-Term Support

Long-term support after go-live. Maintenance, support and further development are handled by the same team in software operations, with no loss of knowledge during the transition.

And after the go-live?

Acceptance marks the end of development, not of responsibility. Maintenance, support and further development are handled by the same team that built the software. Whoever develops also operates, without disruption and without loss of knowledge during the transition.

FAQs

What kind of software does TenMedia develop? keyboard_arrow_down keyboard_arrow_up
TenMedia specialises in tailor-made custom software, without an industry focus. This ranges from specialist applications, databases and portals to interfaces and automation, each built precisely around the client's workflows. The full service covers analysis, design, development, quality assurance, training and, on request, the handover into ongoing operations.
Which programming languages and technologies are supported? keyboard_arrow_down keyboard_arrow_up
Over more than 14 years of development experience, we have worked with a wide variety of programming languages and technologies, including PHP, Java, Python, Ruby, .NET, React, Angular, and more. The selection of the tech stack is always made individually and project-specific.
How long does a software project take? keyboard_arrow_down keyboard_arrow_up
The duration of a software project depends on many factors, such as the scope of the project, project requirements, complexity of the technology, and availability of resources. Additionally, an extensive testing and implementation phase should be planned. A good benchmark is about 6 months for regular applications.
What does collaboration look like during the project? keyboard_arrow_down keyboard_arrow_up
The planning and development process is fully transparent. We set up a joint Scrum board. In this board, the entire project is broken down into individual tasks. We plan the tasks in two-week iterations and present them using MS Teams or on-site. Each task status (Todo, In Progress, Done) can be viewed at any time. The source code is versioned via Git and is continuously accessible to the client. The current state of the application can be accessed via a test server. Moreover, all project parties get to know each other personally, as development takes place in our own team in Berlin.
Who owns the source code? keyboard_arrow_down keyboard_arrow_up
The source code can be inspected unencrypted from the start of development; comprehensive usage rights transfer to the client with the final payment: use, modify and pass on, at any time. Modular development following programming standards and comprehensible documentation ensure that your own team or any other agency can maintain the code.
How is software quality ensured? keyboard_arrow_down keyboard_arrow_up
As an ISO-9001-certified company, we rely on predefined processes geared towards the stability and security of applications. The key to development success lies in team composition. Development takes place in our own team in Berlin, with well-coordinated and experienced developers. Another building block is "Test-Driven Development," which means automated tests that thoroughly examine essential parts of the application at the push of a button. Additionally, we conduct intensive and regular manual user tests.
