"What's the impact, for instance, of another couple of million tourists being in their patch over the course of the Olympics? [It will tell them] have they got enough resources on the road? Have they got their vehicles in the right locations to address the spikes in demand?" he said.
The contract with the East of England ambulance services is one of three Optima has signed in Britain since October last year.
Collectively, the three deals were worth $2.5 million to the company.
While East of England is using Optima's prediction product in the lead-up to the games, the Scottish ambulance service has purchased the company's "live" software.
This delivers real-time recommendations to ambulance staff based on changing data on where vehicles need to be located to provide an area with the best coverage and services.
Optima chief executive Chris Mackay said the British deals added to others in the United States, Australia and Scandinavia.
Optima was founded 14 years ago by students and staff at the University of Auckland's engineering faculty.
In its early years the company provided software models for airlines. Its first project was a system to manage crew rosters for Air New Zealand, saving the airline $14 million a year.
