The platform provides access to resources and key experts to develop prototypes in real environments, and it is supported by the partners’ individual open innovation initiatives.

Yes! You can apply to as many of the challenges as you like, as long as your project offers a solution to each challenge.
I participated but was not selected, can I sign up again?
Yes! You can sign up for the competition as often as you wish to, provided that your product offers a solution for the challenges being launched.

About the location

Will Start4big have a physical space?
No! Start4big assumes that physical space is not the only environment where ideas and knowledge can be shared: innovation can happen anywhere in the world. For this reason, we want to break geographical boundaries and not be linked to a specific place.

Nonetheless, events will be held that will need a physical space, and for these we will count on the venues that Start4big’s partners have in Barcelona.  

I don’t live in Barcelona or in Spain, can I take part?
Yes! We’re looking for start-ups and companies from around the world, without geographical limits.
Will Start4big provide me with a physical space to work with the partners?
The partners involved will decide together with the winning start-ups which resources, spaces and infrastructure will be provided for developing the prototype.

About the winners

Will there only be one winner per challenge?
No! All the start-ups with a project that has the potential to solve the challenge and the ability to work on a pilot project with the partners according to the judges’ criteria will be chosen as a winner of the challenge. For this reason, there is no set number of winners for each challenge.
If I win the competition, will my start-up receive any kind of funding?
The aim of this initiative is to find a partnership model between the start-ups and the companies involved that will benefit both parties, with the objective of developing the solution proposed by the start-up. In principle, investment by the Start4big partners is not envisaged, but this aspect will ultimately depend on the negotiations that take place prior to the project’s development.
Does Start4big provide financial support to pay for subsistence, flights and accommodation for the prize giving event?
Start4big does not guarantee help for transport, travel to and/or accommodation in Barcelona for the prize giving event, however, it may be possible to reach an agreement with the companies involved.
Who will have the rights to the solution developed?
All legal matters and questions concerning intellectual property relating to the pilot to be developed shall be defined during prior negotiations between the start-up and the partners involved.
If I win a challenge, who will I develop the pilot project with?
If you win a challenge, there will be a negotiation phase between the start-up and the partners involved to decide how many partners you will develop your project with.
Can I bring another contributor to develop the pilot?
Yes! You can bring another contributor, but the terms and conditions will be defined during the negotiation phase between the start-up and the partners.
Is my physical presence during the pilot’s development necessary?
It is recommended that the start-up be physically present to facilitate the development of the project, however this will be established during negotiations between the start-up and the partners.

About the associates

What are the roles of judges and ambassadors/associates?
The main role of a judge is to evaluate the projects related to their field of expertise, whilst that of ambassadors/associates is to recommend at least three start-ups with the potential to solve the challenges that are set. Anyone who is interested in working with Start4big in one of these capacities will receive a guide where the requirements, level of involvement, functions and benefits of this collaboration are outlined.
How can I be an ambassador, a judge or an associate of Start4big?
  1. Through direct contact with the organisation. The Start4big team will proactively contact those people whose professional profile suggests that they may be able to fulfil these roles.
