XnTREE aims to support start-ups and scale-ups by directly providing them with access to the market through the Tech Sandbox programme. Every business requires access to capital, but it may be more challenging for start-ups as there are often numerous policies such as an excess amount of participation equity that restrict fluid progress.


Through our wide network includes UCL, Level 39, financial services companies and government organisations, XnTREE guides start-ups within the Tech Sandbox to diversify their market penetration strategies to reach customers in various fields – education, healthcare, mobility, energy, and more.

XnTREE Tech Sandbox (XTX) – Green/Blue/Orange

The XnTREE Tech Sandbox (XTX) recruits companies all year round while the while the Smart City Tech Sandbox (STS) recruits companies during a dedicated period right before the launch of XnTREE consortium’s Smart City Master Planning initiatives.
XnTREE Tech Sandbox (XTX) is a tech accelerator platform that discovers and nurtures startups to connect to global market entry or investment. Green, Blue and Orange memberships belong to XTX.

Smart City Tech Sandbox(STS)

The Smart City Tech Sandbox (STS) model is a smart city open tech cluster that allows at least 25% of the cost of all smart city projects to go directly to competitive SMEs or start-ups. As there is a need for smart cities to focus on various ideas technologies such as software, hardware, and contents, we believe that it is important to exclude existing bidding methods and select operators through an open competition system.
There are two ways to join the STS:


Having had obtained any type of membership in Tech Sandbox and directly applying for STS.


Invitation by XnTREE through tech demo days.

STS Membership requires an annual fee of $80,000 and includes accessibility to information in Green, Blue, and Orange Membership (full cover of Tech Sandbox programmes) as well as qualification to directly participate in smart city projects.


Through the successful completion of the cohort program, companies will be selected and awarded funds to further develop the technology and idea as well as the opportunity to receive seed investment from a fund created by ARK-i Labs or be provided with opportunity to access strategic and financial investors.
In addition, each selected company will be given the opportunity to showcase their technology or ideas when the smart city plans are rolled out, as well as gaining access to different markets.
