Tata Communications ran a $30,000 (£18,000) DataHack14, a simultaneous 24-hour hackathon in London’s Tech City and California’s Redwood City, in the heart of Silicon Valley at the weekend.

The US/UK face-off offered developers the opportunity to come up with comms apps and services from using big data generated from Tata's global comms network.

The grand prize winner will not only walk away with $15,000, but will see their winning idea potentially become a commercially viable product through Tata Communications’ Accelerator Lab.

Tata Communications said it expected participants to turn its big data into applications and services around customer support, loyalty programmes, customer insights, user experiences and new products and services.

Julie Woods-Moss, CMO and CEO of nextgen business at Tata Communications, said: “DataHack14 is the latest in a series of successful crowdsourcing platforms that Tata Communications has created and incubated – tapping into the best creative minds in the most technologically savvy communities to join us in our quest to develop the next big thing for the industry.”

Tech City UK CEO Gerard Grech said: "The uniqueness of this event comes from its cross border nature. It brings together two centres of excellence, Silicon Valley and London, enabling cross-pollination of ideas, perspectives and approaches. This type of collaboration is essential to the continued development of the London and UK ecosystem."

Along with the grand prize winner, the teams with the best ideas in each city will be awarded $5,000. Three of the 10 finalist teams may also be offered a three month incubation experience in Tata Communications' Accelerator Lab.
