About Us
Making sustainable shopping simple.
Our Mission
Leif was built with a simple idea: shopping shouldn't come with a guilt trip. We believe everyone deserves easy access to clear, honest information about the environmental and social impact of the products they buy.
What We Do
Leif is a browser extension that gives you instant ESG (Environmental, Social, and Governance) scores while you shop online. No extra tabs, no hours of research — just straightforward sustainability info right when you need it.
Why It Matters
The choices we make as consumers have real impact. But finding reliable sustainability information is hard, scattered across dozens of certifications, reports, and rating systems. Leif brings it all together into a single, easy-to-understand score so you can shop with confidence.
Our Team
We're a small team of engineers, designers, and sustainability advocates who believe technology can make ethical consumption the default, not the exception.
