Apple and NeXT have a vested interest in collaborating with Hartmut for their design processes. This partnership is crucial to maintain a unique aesthetic and functionality in their products. Both companies share a goal of innovation and creativity, but the potential for unintentionally designing similar products exists, particularly within the competitive tech landscape.

Furthermore, neither Apple nor NeXT, nor any associated design firms, disclose insights into their product design strategies. This secrecy can lead to overlapping visual elements among various companies. Ensuring distinctive design outcomes is essential for both brands' identities and market success, highlighting the importance of careful, collaborative design efforts.
