Our take

Building strong relationships with customers is vital to any eCommerce business, but this is no easy feat. charles solves this problem with its innovative Conversational Commerce platform.

Conversational Commerce utilises chat services like WhatsApp, optimising them for customer communication and integrating them into sellers’ platforms. This makes it easier for businesses to directly engage with their customers, improving consumer spend by up to 60% and driving up customer loyalty.

Conversational Commerce is big business in markets like China, but its adoption in Europe and elsewhere is relatively new. With its significant funding and streamlined, all-in-one solution, charles is well-placed to gain a leading position in this promising new market.
