Your questions, answered.
Everything a company wants to know before supporting us.
What exactly is STEM Racing?
It is the world’s largest engineering competition for school and university students, held in 40 countries. Each team designs, builds and races a miniature F1 car that goes from 0 to 80 km/h in under 2 seconds on a 24-metre track. Teams are also judged on their brand, their stand and their presentation to a jury of professionals.
Who is behind JLMJ Factory?
Four students from Le Mans, France: Jonathan, Louis, Mathilde and Juliette, united in the JLMJ Factory non-profit association. We handle everything ourselves: CAD design, 3D-printed manufacturing, communication and partner outreach.
What will our support be used for?
It funds the car (design, manufacturing, materials), communication (website, software, merchandise), the mandatory stand at the national final and team kit. If we qualify, accommodation and travel come on top. Our forecast budget for the national season is €7,091, detailed in our sponsorship pack.
What does our company get in return?
Visibility with a young audience, schools and the automotive world: your logo on our materials and features on our social media (Instagram, TikTok, LinkedIn, Facebook) and on this website. It is also a concrete way to invest in young people and in tomorrow’s engineering talent.
How much should we give?
There is no minimum: every contribution counts. The bigger your support, the more visible your logo, across four tiers: €1 to €100, €100 to €499, €500 to €1,499, and €1,500 and above.
Can we help without giving money?
Yes! You can become an in-kind partner by providing equipment, a service or expertise, like Garage de la Renaissance. Your logo then appears among our partners, marked “In-kind partner”.
Is our support tax-deductible?
Under French rules, sponsorship can be deducted from profits as a business expense when made in the company’s interest. Patronage (mécénat) may give a 60% tax reduction, but only if our association meets the eligibility conditions; its official registration is in progress. Companies based outside France should check their local rules. We recommend confirming your situation with your accountant.
