Job Description:
Mobile connectivity is a scarce resource for many people [1], and its affordability varies significantly across countries. For example, the cost of 500 MB of connectivity requires just 30 minutes of work for an American but 40 hours for a Mexican.

The telecom space needs a transformation. Our proposition is a unified exchange where actors such as carriers, Mobile Virtual Network Operators (MVNOs), IoT providers, phone manufacturers, and others can trade connectivity. This platform aims to drive down costs and enable new experiences for users and businesses alike.
