• Fast & Fresh

    Fast & Fresh is the first Psychology of Use agency in France.
    Since 2009, we pioneer in User-Oriented Academic Research & User Research.


    For 10 years we developed breakthrough methods on a market that was then very little concerned about users. Agencies were only conducting usability tests.
    If the studies you order always bring you the same platitudes
    and if design thinking doesn't help you innovate, come talk to us and go beyond tactical products.


    We help you conceive services with users, with meaning, with ethics.

  • How we do it



    Today, everyone claims to be a "User Researcher" just like everyone used to claim to be a "UX Designer". We are Psychologists and Sociologists, the ethical understanding of users has been our job for 150 years, we are the only ones to have a real degree to do that. And we are attached to a National Scientific Research Laboratory.



    Strategy is not strategic planning or graphic design or UX Strategy. Without a deep vision of your market and the ability to understand the decisive options, you are going nowhere and your product is doomed to failure. Go beyond tactical products and communication leaflets.



    Design cannot be reduced to a 20mn quick cooking recipe. The soul of Design is to be revolutionary. The soul of Design is to care. The soul of Design is to give people a degree of latitude, to emancipate them, to give them elements of choice, to heal them. It's because you're going to help your consumers that they will stay.

  • Understand your users much more deeply

    You need to understand the needs and expectations of users to make foresight, identify weak signals, identify emerging trends and understand the behaviors of your consumers. Classical consumer studies (interviews, focus groups, UX tests...) do not give you satisfaction or you do not know what to do with the results. Your customer listening is stagnating and surveys, "mystery" field visits and other "empathy maps" are getting you nowhere. It's time to call on expert consultants, Psychologists and Sociologists, able to understand and help users with new testing methods that will give you the keys to new innovation and breakthrough strategies, both in digital and retail.

    We carry out the classics: online surveys, ergonomic audits, user tests, ethnographic studies, mock-up and wireframe tests...

    But above all, we carry out value-added tests: customer usage mapping, prospective tests, psychology experimentation, iconic tests, care tests, constrained tests...

  • Exceed your current and misleading statistics

    Do you need to ensure your acquisition strategies, your e-commerce strategies or simply your ability to dialogue and help your users? Our statisticians in Human Sciences are graduates of ENSAE (INSEE) and whose masters are the cracks of the discipline. They will help you to better understand the profiles and needs of your consumers, to detect unsuspected targets and to base your persona on scientific and tangible data rather than romanticize them with a raised finger.

    Go beyond the universe of descriptive statistics that you are currently using and that mislead you to move on to correlative, causal and predictive statistics tests to identify new levers for action.

    On the other hand, once you understand how people function, you can build the right measurement indicators. We can help you set up the key probes to measure the reliability of your product, its social impact and its real usefulness beyond simple conversion figures.

  • A breakthrough strategy, the real thing

    Marketing Directors, Innovation Directors and Communication Directors, you sincerely want to make a good product for your customers, so you can no longer be satisfied with low-level graphical answers. It's up to you to understand the issues thoroughly and make the right decisions.

    We have helped Allianz, Samsonite, Aramisauto, AccorHotels, UCPA... to review their service strategy.
    But most of all, we know how to make the transition between User Research, Strategy and Design: the worst thing that can happen for you is to do a long work of User Research and Product Strategy and then see all your efforts ruined when it comes time to move to UX / UI. We help you to keep the marrow of your thinking.

    Don't start your design sprints blind anymore. Don't make any more websites or services without knowing where you're going.
