A Marketing Company based in Berlin

As a trusted technology partner, Assutech had the privilege of working with WunderPen, a leading marketing company based in Berlin, Germany. Our collaboration centered around a remarkable project that showcased the fusion of robotic technology and advanced software techniques in transforming traditional correspondence. Assutech successfully assisted WunderPen in developing a groundbreaking system that enables esteemed customers to receive letters in the authentic handwriting of CEOs and leaders of prominent corporations. One of the key challenges we encountered was the inherent nature of non-TTF (TrueType Font) fonts, which are not typically designed for web rendering. Since each iteration of an individual's handwriting varies, it presented a unique difficulty in rendering it consistently on a fixed card format for the web. To overcome this challenge, Assutech took a proactive approach and developed a custom algorithm for the rendering engine from the ground up. This innovative solution ensured that WunderPen could accurately render handwritten letters on the web, capturing the nuances and personal touch of each CEO's handwriting. The result of our collaboration was a seamless user experience, where customers could effortlessly select from a diverse range of templates and fonts, including their own handwriting styles, and have their personalized letters perfectly rendered on the web. By overcoming the technical obstacles associated with non-TTF fonts, Assutech played a pivotal role in empowering WunderPen to deliver a truly unique and authentic communication experience to their valued customers. Assutech takes great pride in our partnership with WunderPen and in contributing to their mission of redefining the way businesses connect with their audience through a seamless blend of technology and the human touch of personalized handwriting.



In collaborating with WunderPen, Assutech embarked on an ambitious project to revolutionize the way handwritten letters are delivered in the digital age. Our primary objective was to overcome the inherent challenges of rendering non-TTF fonts on the web and develop a solution that seamlessly incorporates the authentic handwriting of CEOs and leaders into personalized communications. By achieving this, we aimed to enhance the customer experience, foster stronger connections between businesses and their valued customers, and redefine the standards of digital correspondence.

Develop a Robust Rendering Engine
Assutech's primary goal was to develop a robust rendering engine capable of accurately rendering non-TTF fonts and replicating the authentic handwriting of CEOs and leaders on a fixed card format for the web. This involved overcoming the inherent challenges of variability in individual handwriting and ensuring consistent and high-quality rendering.
Achieve Consistent Replication of Handwriting
The project aimed to achieve consistent replication of individual handwriting styles on the web, despite variations that naturally occur in each iteration. Assutech worked diligently to develop an algorithm that could capture and reproduce the nuances and unique characteristics of each CEO's or Client's handwriting, providing a faithful representation in the digital format.
Ensure Seamless Integration and User Experience
Assutech's goal was to seamlessly integrate the rendering engine into WunderPen's system, ensuring a smooth and user-friendly experience.
