GDC Marketplace provides millions of new potential customers for the businesses in your city.

GDC Marketplace assigns Executive City Director promoters whose job is to create a Local Marketplace in each city, connecting city merchants with YTC token holders.

Assigned Executive City Directors benefit by earning a transaction fee from every buy or sell transaction made with YTC in their designated city. They also earn substantial profits from advertising sales.

Executive City Directors promote to all businesses and merchants in their City and invite them to register their business on the Marketplace. Businesses receive great exposure, and have the added benefit of accepting full or partial YTC tokens in exchange for their products.

Executive City Directors are granted an exclusive city or territory in GDC Marketplace at no cost other than an annual 300 USD website maintenance and virtual office fee.

To acquire an Executive Directorship in the GDC Marketplace, the Executive Director will pay a value of USD 300, valid for 1 year in his area for absolute exclusivity.

This new Business Unit will be available from March 1, 2020.

About us

GDC offers a web service that provides the tools for communities to establish and manage exchange and commerce in their areas, combining conventional means of payment (credit cards, debit, transfers, among others) with others) with YTC lostTokens, through a large virtual store (e-commerce).

On our Marketplace, merchants will be able to publish their products at no cost, agreeing to receive part or all of the payment with YTC tokens.

Therefore, token holders will be tempted to exchange their YTCs on such purchase.

La evolución de GDC UbiZ App

Beginning, present and future


Launching the application
September, 2015

Mobile telephony broke into the world market with unprecedented strength. In addition, in the commercial sphere, customer loyalty was the issue that most concerned entrepreneurs. So we began to work on the idea of linking loyalty to mobile telephony.

September 2014. We started working on the creation of UbiZ App, the loyalty tool via mobile telephony. To do this, we had a vision: nothing better than the technology of push notifications to retain Loyalty

At the end of the month, they were charged a 5% commission for all sales and 5% more for all purchases on these platforms, these same were also developed in many countries and for more than 20 years but without any significant expansion.


UbiZ for users and UbiZ for companies

El mercado nos volvió a sorprender: UbiZ captó inmediatamente la atención de los anunciantes y alcanzó las 100.000 descargas en los markets de Android y Apple.

Más tarde, diseñamos un programa comercial mediante Licencias de marca e incluimos el producto sin costo dentro de los paquetes de anuncios Super AdPack, Ultra AdPack y Pro AdPack de AiYellow.

Hoy, UbiZ se expande y avanza presentando la utilización de la herramienta UbiZ for Business a empresas con valores sin competencia en el mercado, y UbiZ for People, la cual promueve la interacción entre usuarios y empresas mediante sorteos y premios, con acciones que fortalecen la fidelización. Además, a través de sus directores, UbiZ ofrece asesoría completa sobre la utilización de la herramienta.


To increase city directors
2020 onwards

Our desire is to participate actively and reach the numbers of users that we have achieved in AiYellow.

In a market increasingly focused on mobile cellular technology, our goal in the short term is to open as many commercial directorships as possible to strengthen the application and disseminate its use. According to our estimates, the number of users should grow exponentially when using the Pro Database System.
