Stamp Free Limited, the digital postage stamp company, has launched its Stamp Free Digital Postage Solution™. Initially targeted at postal and logistics sectors, the solution is the first in the world to be offered by a company that is independent of postal services.  Stamp Free has successfully raised £300,000 to ramp up commercial traction and further develop the Stamp Free Digital Postage Solution™. The funding was led by Dr. Ronjon Nag’s Silicon Valley-based R42 Group and high profile Cambridge Angels investors.
