Which start-ups can participate?

We will choose start-ups that are at an advanced stage of maturity, with functional prototypes developed or a product that is ready to go out to the market. At Start4big we are looking for:


Start-ups with a functional prototype or an innovative technology seeking partnerships to make their business grow


Start-ups with a commercial product or service that can be adapted to any of the sectors where the partners operate


Start-ups with  a product that has been tested and proven in the market that want to scale up to millions of consumers

Which challenges do we want to tackle?

How could we track the activities of the clients in real time to personalize their experience?
Companies are evolving and innovating to offer personalised services to their customers. Nonetheless, it is still necessary to get to know the user better and develop tools that allow us to register patterns of behaviour, with which we could anticipate their needs and offer solutions in a personalised way.

How could we help users to control and manage better consumption at home?
Homes are increasingly connected with people’s devices and wearables. Because of this, citizens are demanding better control over their consumption: they want to know how much, how, and on what they are spending their money, to be able to optimise it. It is necessary to move forward with data monitoring and management systems in order to offer information on the effects and to allow the user to act on this.

How could we improve customer experience and/or reduce digital transactions costs of services & products?
Currently, digital transactions involve long and costly processes for users due to the need to provide numerous pieces of information and to go through an intermediary for authentication. We need to evolve towards new digital transactions to be able to offer services that are personalised and adapted to meet consumers’ needs, immediately and without additional costs.

How could we improve new services taking advantage of communication between different devices, vehicles and infrastructure?
Customers are demanding “smart” products that communicate with one another. There is a need to create a system that guarantees communication between devices and infrastructures in different environments, to evolve products and services in real time and personalise them for each customer.
