Proof of concept it an important aspect for both investors and real estate owners as there needs to be reassurance that there's a market and economy for shareable workspaces that can be rented (or rented out) using cryptocurrency.

The proof of concept is going to take place in to two separate stages first of which being the establishment of the first five established locations followed by the continued expansion in to new locations which will be determined by shareholders.
The founders have strategically determined the first five locations in cities that continue to thrive and grow with new start-ups and tech entrepreneurs. Primarily, the goal is to rent shareable work spaces to new companies, project related team startups and branch offices.

What's unique about this particular cryptocurrency (PBT) is that investors, instead of using them to rent workspaces can rent them to individuals at a negotiated rate so returns/profits can easily be made.
As of now, Primalbase has already announced that there's currently a proof-of-concept already established in Amsterdam where they've already received recognition for their innovative platform and well-known tech entrepreneurs are already joining aboard with endorsing Primalbase for their platforms features and forward-thinking platform leaders.

Primalbase in Amsterdam

Following the guidelines outlined by the Primalbase platform, Amsterdam is currently renting out workspaces exclusively to PBT holders and it's proving to be quite a success with a large dedicated audience already taking advantage of using PBT to have a quiet, comfortable and relaxed environment to work in.
In order for continued expansion to occur, founders of PBT have announced that investors and renters of these spaces are key to this being a viable endeavor as expansion (especially in international markets) will require a large amount of capital.
The strategy for expansion at Primalbase has been publicly shared and one was that we saw coming since there's only 5 locations from the start that will be operational. Currently, the plan is to strategize the marketing of these initial locations to recover startup costs (investment recovery) at which point profits will be used for infrastructure acquisition and development costs so additional locations can be opened.

Of course, the future of Primalbase will be somewhat foreseeable during the first 1-2 months of its release as we'll be able to see how many investors, community members and landlords entrust the platform to provide a return.
Many are speculating though that Primalbase is going to be a huge success as we're in a digital world and Primalbase is going to be providing a solution for a major issue and with so many startups in many markets there's not going to be any shortage of tech entrepreneurs that will be lining up to rent a workspace at one of the many locations.

The Future of Primalbase

With nearly 14,000 shareable workspace establishment’s worldwide and annual growth of over 10% for new tenants coming to the market looking to rent office space for work or meetings, Primalbase has an incredible proof-of-concept based simply only on market statistics.
