Question: “Initially there is a high number of players and then over time consolidation happens ”  Klaus Helmrich  said on Wednesday at the launch of a global user organization for Siemens’ MindSphere platform  which competes with General Electric’s Predix and others to help customers gather data from machines.
“I don’t think we will end up with one platform worldwide. There will be a handful or two handfuls in the mid to more distant future ”  Helmrich  said  comparing the proliferation of industrial software platforms with the smartphone industry  which has ended up being dominated by Apple and Samsung.
Siemens already has more than 800 000 intelligent sensors in buildings and machines  including trains and healthcare equipment  putting it in a strong position   Helmrich  said.
“It is a solid basis for the start of the business and makes us optimistic about scale effects ”  he  said  adding that being first to gather a critical mass of software developers and users is crucial to winning customers  much as Apple’s large developer community made its app store the most attractive.

Answer: Klaus Helmrich
