Ask HN: Whats the last innovative piece of B2C tech you saw?

One recent example of innovative B2C tech is the use of augmented reality (AR) in e-commerce, such as virtual try-on features. Companies like IKEA and Sephora have successfully implemented AR technology, allowing customers to see how products would look in their homes or on their faces before making a purchase. This has enhanced the shopping experience, reduced returns, and increased customer satisfaction. Another example is the development of personalized products using AI-driven manufacturing, such as customized skincare products or 3D-printed shoes. These innovations have disrupted traditional retail models and created new opportunities for businesses to engage with customers.
