IWE-idea worth express what we are doing.

First, we will source special application, find the experts in the special area, Analysis the technic portions and then find the right people form a team.

Second, The team will build a demo to show how the system works and present the ability building a beauty product. at the same time, we have a service from IWE to help tell the story and explain the system of the application by using pictures, videos, and articles to the potential customers through the internet and social media network.

Third, the demo will be available on the online shop after it finished. The potential customers will pay for the demo and check the function have the basic idea about how it works and know the core value of this application, then a new idea brings out according to the local market and their key resource to their customer.

Fourth, After checking the demo customer will have the new idea for their application and confirm the ability of the team, then the customer has to pay a fee for customized their new product.

Fifth, IWE has a good management for the local supply chain and will source the feasible components and device from the local and international suppliers, guarantee the ability and quality when the new products run mass production.

Sixth, Using the international logistical delivery the products to the customer all over this world.

Value and impact

We take off the best skill and talent from a talent people and input that skill and talent to solutions, we help to present and explore that to customers, Customer can combine the local culture, market and requirement to the solutions to customized special products, bring the value from skill people to the end customers.We want customer can have full service for supply chain and talent people at one station.We want the talent people to have more time with their families and friends or for traveling.
