About Zerofy

We're Zerofy, and we help households decarbonise.


We observed that people want to reduce their emissions, but are often confused about where in their household the big emissions contributors are. Worse, they also suffer from unnecessary complexity and friction when trying to implement solutions.

However, as drivers of economic demand, households can play a major role in reducing carbon emissions. With 70% of global carbon emissions indirectly attributable to households (directly approximately 20%), people have a lot of power to make changes, right at home. While consumers may sometimes feel powerless, they can have a major impact right now by reducing emissions through electrification of personal mobility,heating, and cooking, but also through participating in decentralized (solar) electricity production and storage. Additional steps, like favoring low-carbon alternatives for food and consumables can have further impact.

What’s standing in the way of running a lower carbon household is often simply a lack of timely insight about CO2 impact and too much complexity when switching to lower carbon alternatives for energy, products, and services.

Zerofy’s app solves this problem: it continuously measures household carbon emissions automated and in real-time. Based on these insights, Zerofy then helps households to decarbonise through personalized actions and by providing recommendations for lower-carbon products and services.


Zerofy is a technology company with an energy app that helps households decarbonise and shift towards becoming fully electrified. Zerofy was founded in 2022 by Criss Uudam and Till Quack, entrepreneurs and product builders with complementary expertise across software development, renewable energy and financing.

The company has been featured in Fast Company and TechEU, and in 2022 raised pre-seed funding from San Francisco-based Union Labs and a group of angel investors. The app is available in the iOS App Store in Europe and the US.
