Hightail is a cloud service for file sharing and creative collaboration. It was founded as YouSendIt Inc. in 2004 and renamed Hightail in 2013. It is offered as a hosted web service, and the vendor's website presents it as part of the OpenText family, with a focus on file sharing and creative collaboration.
OpenText acquired Hightail in February 2018, and OpenText is headquartered in Waterloo, Ontario, Canada. Before the acquisition the company was based in California, and its employees moved to OpenText's San Mateo office in 2018. The vendor's website does not state where customer data is hosted, and the service is not open source. For a European organisation the main points to check are the US operating base, the Canadian parent and the hosting location, which should be confirmed directly with the provider.
