- Condu - 2004/5 With Steven Tover, we explored two concepts. One was a Regional Network Address Translator (RNAT) for use by ISP's. This device would create large private networks that could then have safe one-way access to the Internet. This product was cancelled due to the weakness in the ISP market. Our second concept was for a Forensic Auditing System that would capture months worth of network flow information for use in tracking down network intrusions and penetrations after the fact. Although we received positive industry feedback, we were unable to generate sufficient venture capital.
- QLusters - 2001 As an Entrepreneur in Residence (EIR) at Israel Seed Partners, Offer Shoshan and I conceived and developed the concept of using multiple commodity Linux servers as a single virtual operating system. Offer went on to found QLusters to develop this vision. I currently serve on it's Board of Advisors.
- PictureVision Inc - 1995/00 Together with Yaacov Ben Yaacov and Phil Garfinkle, I founded PictureVision to scan, store and merchandise digital pictures over the Internet. We developed Kodak's PhotoNet system with over 40,000 drop-off locations. We also developed AOL's You've Got Pictures product to provide long term storage and merchandising of consumer images.
- Unnamed - 1993 Together with Tony Mason, we proposed developing a licensed version of AFS for the new Windows 3.1 platform. Our goal was to sell pre-packaged AFS servers and clients. The project was unable to proceed due to contractual issues with Transarc.
- Transarc Corp. - 1989/94 Transarc was involved in building two distributed file systems, AFS and DFS. It also built a distributed transaction processing toolkit called Encina. I was a day-one employee. Initially, I developed and implemented the software engineering infrastructure. I went on to design the distributed two phase commit protocols. I completed my tenure there as manager of the DFS project.
- Expert Technologies Inc - 1985/6 Expert Technologies built an AI system to paginate yellow pages. I was a lowly programmer and system administrator. This was my first start-up experience and one that I am happy to have put behind me.
PictureVision was sold to Kodak in 2000.
Transarc was sold to IBM in 1995.
