Purpose and Context

Sustainable Softworks is an award winning Macintosh software developer inspired by building tools to make technology more accessible and improve the Mac user experience.

The company was founded in 1996 by Peter Sichel to build a software IP router for the Mac, and was instrumental in ushering in the era of reliable network connectivity and Internet sharing with IPNetRouter (NAT router), IPNetMonitor (network diagnostic toolkit), and IPNetTuner (TCP/IP tuner for improving network performance and compatibility). IPNetRouter received a 1999 Macworld Editor's Choice Award for Best Network Utility and was licensed to Apple Computer as part of the original AirPort Software Base Station.

Sustainable Softworks' dedication to customer support and continuous improvement has attracted many delighted customers as it adds new products and features to extend the Mac in areas that have otherwise been neglected.


Peter Sichel, Chief Engineer and Founder of Sustainable Softworks, has a Masters Degree in Computer Engineering and has worked as a software professional in a leading fortune 100 company for over 14 years. His broad background in both hardware and software combined with strong process and communication skills offers clients an unusually comprehensive view of information system issues. Read an interview
