Web Summit Rio celebrates emerging businesses making a positive difference in the world. Here are 10 Impact startups from our network. 

At Web Summit Rio, we’re dedicated to achieving the United Nation’s Sustainable Development Goals (SDGs). That’s why we’re celebrating Impact startups, the emerging companies trying to make a positive impact on their communities, industries and ecosystems.

We want to shine a spotlight on the startups within our network that are striving to achieve the UN SDGs.

Here’s a list of some of the Impact-focused startups joining us in Rio de Janeiro this April:

Rentbrella uses technology to create innovative solutions for consumption and disposal, fostering valuable connections between people, companies and cities.

TakeCarbon is the first fully open and decentralized environment for promoting impactful initiatives, revolutionizing the way carbon credits are tokenized, traded and retired on a global scale through Web3 technology applications.

AntiAlgas Soluções Ambientais

AntiAlgas Soluções Ambientais designs and manufactures ultrasound equipment to control the proliferation of algae, cyanobacteria, golden mussels and aquatic parasites.

The ultrasonic anti-algae system emits ultrasound waves that create a sound pressure band below the water surface, approximately 25cm deep, interfering with the algae’s buoyancy system and preventing it from reaching the water surface to receive sun and carry out photosynthesis.

The Impacto platform is an environmental, social and governance solution for companies. It connects donors to social projects that have serious work to give them visibility, structure and transparency.
