We build great
Whether it’s mobile, web, or desktop apps; embedded systems; IoT; cloud; or AI-powered solutions: We develop exceptional custom software that aligns user needs with business goals.
We build great
We develop customized, user-centered software for:
Your software development partner
Software tailored to your needs
Off-the-shelf solutions quickly reach their limits. Custom software, on the other hand, adapts precisely to your needs. We develop custom, user-centered software that is tailored specifically to you, your specific circumstances, and your users.
Our service portfolio
We translate user needs into intuitive user interfaces, ideas into clear product visions, and requirements into robust software applications. We strategically use AI-powered features to bridge the gap between users and technology. At the same time, we also understand the technical side of things: through the development of embedded systems, hardware-oriented integration, and a special focus on the seamless interaction between hardware and software.
The agile mindset of everyone on the slashwhy project team is impressive and positively contagious. We work with slashwhy as equals in agile project teams and reach our goals more quickly together.
Markus Rose
Director CHARX control Division Charging Infrastructure at Phoenix Contact
We can save a successful operation within the application and reuse the template to install the same doors espacially with large construction projects. This is clearly a benefit and a huge value of the app.
Tobias Lange
Projektmanager at Hörmann
We found a partner in slashwhy who doesn’t just deliver code but supports the entire process from conception to implementation, truly identifying with the product and actively improving it.
Friedrich Laube
Director Digital Products & Services Smart Home at Miele
As individual and customer-oriented as our company is in the field of agricultural machinery technology, we have come to know slashwhy as individual and user-centered in the field of software development.

PO & IT-Business Partner at Grimme
The major benefit of the solution developed with slashwhy is that we can run the further development of the series products in parallel with the new development projects.
Axel Schröder
Director Advanced Engineering at CLAAS E-Systems
We always feel that slashwhy takes full ownership of the product. Everyone involved fully identifies with the product. This is different from other service providers.
Dr. Melanie Schuh
Product Management at W&H
slashwhy first supported us in the frontend area and then gradually evolved into a fullstack partner that implements subprojects autonomously for us.
Henrieke Otte
Product Owner at 365FarmNet
It is very important for us to have an intuitive operation using a modern UI. Our customers should not be annoyed with the technologie, they should have fun with the products and the application.
Oliver Kortekamp
Team Leader & PO at Oase
By introducing agile methods together with slashwhy, we have successfully professionalized our software development process.

With slashwhy as a trusted partner, we work more efficiently, delivering value faster while ensuring long-term success.
Issam al Mutawaly
Chief Operating Officer at ElectroFleet
We were initially very skeptical about agile contracts. However, I can now clearly say that slashwhy's agile contract model makes my work as a PO much easier.
Dr.-Ing. Nils Rottmann
Product Owner at Hako
Scrum or even other agile management methods that we learned about with the development of IRIS were completely new experiences for us. These are now applied even as far as to strategy development.
Ralf Schulz
CFO at Höfelmeyer
I am enthusiastic about the daily cooperation with the team from slashwhy, which works vigorously. Also it is great that we get the possibility to help our customers to get better, more efficiently and more sustainably within their production.
Jonas Häntzschel
Product Owner at Höfelmeyer
Because of the agile project with slashwhy, the guidlines for project management at Hörmann were extended that we not only have the classic phase plan, but also use hybrid and agile approches now.
Tobias Lange
Projektmanager at Hörmann
Thanks to IRIS I can save money as a customer from Höfelmeyer: by reducing the loss of raw materials, by making an easier process because I digitize them and save time, but also because I get final evaluations from the software.
Viktor Rempe
Technischer Leiter at Höfelmeyer
We built our energy management system together with slashwhy, from the initial idea and concept all the way to continuous product development. We truly value this holistic approach and complete reliability.
Dr. Stephan Alberternst

We are the innovative and reliable market leader in our industries. Controlling our products with the app and creating a whole new user experience is a great challenge for the team and is also a lot of fun.
