Our take
In a world where personal data is freely exchanged for services, many consumers remain unaware of how much data is collected by platforms like Instagram and Facebook. Even fewer know how to control its usage or benefit from it. Sumus aims to change that, offering users a way to reclaim control over their data while addressing a broader mission: transforming the landscape of sustainable fashion and beauty through AI-driven solutions.
Sumus is an AI-powered ESG (Environmental, Social, Governance) marketplace that empowers brands by enhancing transparency and scalability in their sustainability efforts. By evaluating and improving the ESG performance between environmental impact and ethical consumer choices. Sumus provides tools for brands to ensure they meet growing demands for sustainability while giving consumers access to verified, eco-conscious products.
Though still in the early stage of development, Sumus has the potential to make a significant impact in the marketplace. With its innovative approach to combining AI, ESG, and sustainable commerce, the company stands at the forefront of the movement towards more transparency, ethical, and sustainable business practices in fashion and beauty.
