A British online contacts and calendar suite is among the finalists to be picked to contest the title of best European web start-up.

Anywr.com unifies address book entries from multiple webmail and offline email clients, and synchronises information with desktop applications and mobile phone handsets.

It has been selected by organisers of Startup 2.0, a Spanish competition to find the most innovative new Web 2.0 sites across Europe.

Fifteen contestants, revealed in information supplied to Read/Write Web, have been selected by visitors to the contest website and will on Thursday be whittled down to just five grand finalists by judges.

They will compete for the Startup 2.0 title at the Guggenheim museum in Bilbao on May 24.

Anywr.com was founded in February by Martin Caleau, a software developer focusing on SyncML and Ajax, and Diego Giol, a former World Health Organisation software engineer.

Both founders are from Mendoza, Argentina; Giol is reading for an MBA at Oxford University.

Other British Startup 2.0 nominees which failed to make the final 15 include TeeMint and PluralList.
