What is ProProfi?

«ProProfi» - the first construction project, which is integrating Blockchain technology, will provide the connection of cryptocurrencies with the real sector of economy through a token Leadium (LDM). It will change the construction services market towards simplicity and confidence. Every Customer can trust a partnership with the Contractors on 100% . The «Pro Profi» database of our Contractors is being checked and actualized by moderators regularly, like nobody else among construction services in USA. Our ultimate goal is to create a community of the happy Customers, who are 101% satisfied with provided services and ready to recommend «Pro Profi» to relatives, friends and colleagues.

The Customer adds his project, and first 5 Contractors who bought the access to this project leave their offers including the price, conditions and terms. The competition between Contractors allows the Customer to reduce the expenses for services. At the same time, limited number of Contractors increases the chances of getting that order. The private professionals compete with the companies on an equal basis and also could get big contracts if they have the required licenses.

After all, Customer compares all offers exploring the Contractor’s profiles (rankings, projects, reviews). Next step is to choose the right Contractor and sign a contract. There are no additional calls or agents with extra fee. Customer finds trusted Contractor and saves not only time but also 30-50% of the cost.

How do we make money?

Our clients are Contractors. We sell top positions in catalog and advertisement. Other services are paid in Leadium. The monetization model tested and showed its effectiveness.


We don't make money on selling orders to proffesionals. The orders can be paid only in Leadium, that contribute to Leadium quantity decrease (all used tokens for pay for orders will be destroyed constantly) and exchange rate growth.


Some Customers call professionals from catalog instead of leaving an order on the website. Contractors ready to pay for positions according to their specialization, and we make money on it.


The demand of hidden advertisement has a positive trend, when classic banners lose their efficiency. The companies who produce construction materials glad to pay for such promotion, advertisement in the form of not obsessive adviсes on aspect of buying products.
