Slide through a few examples of completed solutions

Any complete product represents the culmination of many complex processes involving a vast array of people, technologies, and actions.
Many Hoffmann + Krippner customers know what they want, but they may not have the capabilities or staffing in-house to design, prototype, test, and produce their vision. Often, product development represents such a huge undertaking that many companies find themselves facing ballooning budgets and slipping schedules with no finished product in sight.
For Hoffmann + Krippner, developing outstanding products is just another day at the office – and we can bring that same ease and confidence of turning an idea into a marketable product to your organization.
We host all the expertise, talent, and machinery in-house needed to render a completely realized product start-to-finish. With a diverse array of talent – as well as tight vertical integration between departments that specialize in software, hardware, and everything in-between – we can streamline almost any product development effort.
Our specialists are intimately familiar with the requirements of many different industries and technologies, and we draw from that deep well of knowledge to advise customers on how to best address their own customers’ needs. We can help create solutions with complex requirements in the fields of mechanical engineering, electrical engineering, military technology, automotive engineering, aviation, medical applications, and more. The standards and quality guidelines of these industries are part of our expertise, so that we can ensure products meet requirements for materials, tests, and inspections.
We then work with our customers through all stages of product development:
- Extensive consultation
- Design and engineering
- Prototype manufacturing
- Testing and quality assurance
- In-house production (both small series and large scale)

The customer’s needs govern every aspect of product design, development, and testing.
Hoffmann + Krippner emphasizes extensive consultation and customer support, no matter the project. During development, our team works closely with customers to meet their needs in the most efficient and effective way.
About ten percent of the total workforce at Hoffmann + Krippner works in development and design. This team collaborates closely with clients to develop the innovative concepts that can turn their products into marketplace successes.
Each project presents Hoffmann + Krippner with new challenges, so our team incorporates a wide array of skills and knowledge that it can apply to every project. That ensures we can meet any challenge thrown our way and deliver maximum project success.
In turn, everything our team does – from selecting hardware components to programming the interface, from designing the system to testing prototypes – is geared toward ensuring the customer succeeds in creating the perfect product for their needs.
Hoffmann + Krippner software solutions ensure flawless operations and seamless interactions between machine, input unit, and user.

We support our customers with:
- The development of firmware based on your specific requirements
- The development of keyboard protocols
- The integration of touch pads, mouse pads, and touchscreens (capacitive and resistive)
- The development of user-defined standard interfaces

Input devices require more than just hardware to work; software is equally fundamental to modern products, devices, and equipment. Just as your products and equipment rely on input devices (from membrane switch keyboards to touchscreens) to work as intended and benefit the end-user, those input devices themselves rely on software for optimal operation.
Software is the interface that connects the required functionality of the input system with that of the product. To overcome common problems of complex, time-critical and memory-scarce embedded software successfully, BOTH expert coding and development knowledge AND corresponding hardware technical expertise is required; and programming must be completed in close conjunction with the hardware.
In short, no product or input device is complete without excellent software systems baked into it – and ideally developed alongside.
That’s why, decades ago, Hoffmann + Krippner grew from building simple membrane switches to designing and engineering complex, complete input systems. Realizing that suboptimal communications between the input unit, the machine, and the user would result in malfunctions and unexpected output, Hoffmann + Krippner began to apply our technical and engineering expertise to the challenge. Today, we create products that work as efficiently and beautifully under the hood as they do on the surface.
Hoffmann + Krippner already has everything you need to design and build world-class products, ready to go.
