Who we are

XnTREE was founded in 2016 by partners and executives of ENTIQ, an in-house accelerator within Level 39 based in London. Based in the UK, it is a tech accelerator that has been successful in running cohort programmes for 300 start-ups at Level 39, where more than 10 companies have became unicorn startups. Recently, XnTREE has put its efforts into expanding the program that it created within Level 39 and Cognicity (Smart City Challenge programme in London) in Asia.

Since its incorporation, XnTREE has been fully dedicated to smart city master planning by creating a ‘Smart City Consortium’ for central governments and municipalities, in addition to recently playing a vital role in operating “Smart City Tech Sandboxes”, created by ARK-i Labs.

In 2019, XnTREE expanded its global footprint with the opening of an office in New York, USA, in addition to its offices in London, UK and Seoul, Korea.
