“Pragmatic and flexible collaboration”

Spartner has created a customized portal for us for the accountability of large-scale collaborative projects. This enables us and our partners to execute and account for their plans in a shared environment that is secure, transparent, and manageable. The pragmatic and flexible collaboration with Spartner has ensured that we have quickly achieved a functional and user-friendly environment.

“As a business you must dare to move forward”

Innovation and change are not always welcomed with equal enthusiasm by our employees, man is a creature of habit but as a company you have to dare to move forward and the need for a contemporary drawing program for the realization of various constructions with our Masterbloc bricks was high. For us but also for Spartner, this challenge was a bit of pioneering and together we had to overcome some hurdles to arrive at a beautiful and efficient business tool. A development and learning process for both parties, in which the feedback of questions and desired adjustments by our employees to Spartner was always in good consultation and we could count on quick feedback and targeted solutions. We continue to exchange experiences with Spartner and look back and forward to a successful collaboration.

“A deal is a deal”

Yield.inc is a new asset manager in the Netherlands that focuses on excellent customer experience, sustainability and technology. When faced with the question of whether to develop our platform in-house or with a partner, we got in touch with Spartner. We are still 100% behind the choice for Spartner because we own the source code and with Spartner, a deal really is a deal, whether it concerns the delivery date or the agreed budget!

Frequently asked questions

Are you interested in collaboration, but still have some pressing questions? This quick Q&A might offer a solution.

What types of platforms and apps do you actually develop?

In summary, we are able to realize almost any online project. Some examples include:

Web applications, Project management platforms, 3D builders, AI tools, Booking systems, ERPs, Customer and partner portals, Neobank & fintech apps, Online patient records, Legal tech suites, E-learning platforms, Survey and feedback systems, API integrations and development, E-commerce web applications, CRMs, Portfolio management platforms, Chatbots and service tools, Social network platforms, and more.

Is it necessary to always take a complete sprint?

No, that does not align with our vision of partnership. We work with flexible project or feature roadmaps. As a first step, we conduct a deep-dive session. During this meeting, our architect can brainstorm with you and define the project scope clearly. Once all information is gathered, we can adequately estimate the necessary time and costs.

In which programming languages and technologies are you specialised?

Our team is full-stack, proficient in both backend and frontend development. For backend, we often use PHP/Laravel, .NET, C#, or Python. The application data is stored in SQL (MySQL, PostgreSQL) or NoSQL (MongoDB, Elasticsearch, Redis) databases.

On the frontend side, we work with powerful technologies such as JavaScript, Livewire, TailwindCSS, Vue.js, ThreeJS, TypeScript, Nuxt.js, Flutter, React (Native), and Angular. We create UX/UI designs using Adobe XD, Figma, UXPin, or Photoshop.

This is just a small selection of our expertise. From DevOps to AMQP, we are happy to delve deeper into the technologies that best fit your needs.

I am not satisfied with my current developer(s). What now?

We would be happy to assist you in this unpleasant situation. Often, we can take over the SLA (service level agreement) and further development of your project. Critical issues will be addressed promptly. Afterwards, we ensure a smooth collaboration with a professional roadmap and a reliable SLA.

In addition, we regularly offer second opinions and code audits. This will give you a clear picture of the quality of your application.
