TickEx, the UK-based vertical search engine for live events, has expanded across the Atlantic by opening an office in California.

The company, which launched a beta version of its site in the UK in June, says its US version will have 5m tickets in its index when it goes live.

It follows a similar move earlier this month by viagogo, the European online ticket exchange.

TickEx, which is privately funded, allows users to browse and compare tickets by searching for artists, venues, cost, date and seat location. It lists items from both primary and secondary sellers.

It says the market for live tickets is worth £2.6bn each year in the UK – but presumably much greater riches await across the pond.
