The ClustTour idea was submitted to the OpenFund  - a Greek venture capital aiming at financing and supporting promising high-tech start ups - and received positive feedback with respect to its technical aspects. In addition, it received valuable feedback regarding the potential for exploiting the underlying technologies.

Reviewers pointed the utility of the service for travellers, as well as the technical soundness of the idea and the development team. In addition, they recommended the redefinition of the business model such that the prospective business can be sustainable from well-specified (and plausible) revenues.
