Inside Les Savants Fous
The right questions before you start
The concept at a glance
Les Savants Fous was created to change how children view science, replacing textbooks with manipulation, curiosity and wonder. Every session is designed to generate a genuine "wow" moment, whether it's a birthday party, an in-class workshop, a corporate stand or a science club. Since 2021, the brand has expanded with Les Savants Fous Tech, adding robotics, robot-building and coding to its offering, aligned with primary school curricula. This breadth of formats — birthdays, workshops, shows, stands, clubs and internships — means franchisees benefit from a genuinely diversified activity calendar rather than a single-service model.
Why join this franchise?
The network highlights the absence of any structured, direct competitor offering such a wide catalogue of scientific entertainment services. Franchisees run their own local agency with considerable autonomy, while still benefiting from the guidance of the network's founder and fellow licensees. Key strengths include:
- A unique positioning blending education and entertainment for children
- A fast-expanding sector with limited direct competition
- A varied client base: families, schools, councils, leisure centres and businesses
- Ongoing support from head office and peer licensees throughout the franchise journey
- No obligation to secure commercial premises, offering flexible start-up options
Who they're looking for
Les Savants Fous welcomes a broad range of profiles, provided candidates share energy, ambition and a genuine interest in children's education. The brand particularly values:
- Managers seeking a career change with strong organisational skills
- Experienced technical or field sales professionals
- IT or engineering professionals wanting more purposeful daily work
- Teachers passionate about education but seeking greater independence
There is no strict development quota; the network prioritises finding the right people over rapid, unchecked expansion.
Requirements and investment
To join the network, candidates should have available personal contribution of around £10,000, with total investment to launch the business — including initial franchise fees of approximately £16,500 — estimated at around £30,000. This covers training, initial stock of experiment kits, marketing support and integration into the network's operational systems. Commercial premises are not compulsory, which helps keep entry costs manageable, although a visible location is recommended to welcome the public. Ongoing support includes initial training, launch assistance and continuous access to the network's know-how and community of licensees.
