Dec 21 (Reuters) - Travel technology company Via said on Tuesday it had confidentially filed for an initial public offering in the United States. The New York-based firm develops public mobility systems by building a network of buses, shuttles, wheelchair-accessible vehicles, and autonomous and electric vehicles. Via is the latest to join a clutch of companies looking to cash in on high investor appetite for technology stocks this year in the United States. Enterprise software makers Samsara Inc (IOT.N) and HashiCorp Inc (HCP.O) recently floated their shares in New York at valuations above $10 billion each. Via did not reveal the number of shares or the price range for its proposed offering. Founded in 2012, some investors in the company include accounts managed by BlackRock (BLK.N), ION Crossover Partners, Koch Disruptive Technologies and Exor. As of Nov. 30, Via said it had forged partnerships with 500 companies and expanded its footprint to 35 countries. Last month, it raised $130 million in fresh capital as part of a late-stage financing round led by asset manager Janus Henderson, valuing the startup at $3.3 billion. read more Reporting by Manya Saini and Mehnaz Yasmin in Bengaluru; Editing by Shinjini Ganguli and Uttaresh.V
