From 11 to 14 June 2025, the Numendo team was at Viva Technology, the essential technology innovation event in Paris. Alongside our partner Perfitt, we presented an innovative solution dedicated to the online footwear sector: shoe-size recommendation technology based on artificial intelligence and 3D scanning.
In a context where product returns have a strong impact on profitability and where the customer experience is becoming a genuine loyalty driver, Perfitt stands out as a high value-added solution for brands and distributors.
This is a concrete step forward for all e-tailers, marketplaces and retailers looking to reduce returns, improve their conversion rates and offer a more personalised shopping experience.
The key takeaways from VivaTech 2025
This 2025 edition confirmed that artificial intelligence has become a strategic tool for companies, going well beyond the buzz.
Major figures such as Emmanuel Macron, Jensen Huang (NVIDIA) and Arthur Mensch (Mistral AI) hammered home the importance of applied AI for industry and commerce.
Among the innovations presented:
- AI in healthcare (with AlphaFold for medical research)
- Brain-based authentication (Neuro ID)
- The integration of AI into retail, as was brilliantly demonstrated by… Perfitt, our Korean partner
VivaTech 2025: the flagship trends to remember
The 2025 edition of VivaTech confirmed one thing: artificial intelligence is no longer a topic for the future, but an immediate business lever. The event brought together more than 180,000 attendees from all over the world to discover the innovations reshaping the retail, healthcare, space and mobility sectors.
Among the highlights, the much-noticed presence of President Emmanuel Macron, accompanied by Jensen Huang (CEO of NVIDIA) and Arthur Mensch (CEO of Mistral AI), underlined France’s and Europe’s determination to play a leading role in technological sovereignty and in the deployment of applied AI.
Generative AI established itself as a cross-cutting theme, with concrete use cases presented in fashion, logistics, e-commerce and healthcare. Special mention goes to the AlphaFold project (Isomorphic Labs), which is transforming drug discovery, and to start-ups such as Ashirase, which use sensors in insoles to guide visually impaired people.
Canada was named country of the year for its leadership in AI, and many well-known brands took advantage of the show to unveil their projects in fashion tech, neural authentication and phygital experience.
On the retail side, intelligent recommendation, returns reduction and behavioural analysis solutions emerged as priorities for distributors seeking to reconcile commercial performance with customer satisfaction.
Perfitt: the solution that reduces your returns and increases your conversion rate
Perfitt is a Korean start-up that is revolutionising the purchase of shoes online (and also potentially in store).

How does it work?
- 3D scan of the foot via smartphone (accuracy ±1.4 mm)
- Access to a database of the internal shapes of shoes
- AI algorithm to recommend the ideal size, with personalised adjustments (foot shape, width, etc.)
The results speak for themselves:
- +20% online orders
- –55% returns among Perfitt users
