How We Compile Our Insights

Combining function and scientific fact is how we find the best of the best

Finch is powered by a proprietary algorithm that puts products through the wringer.

Our technology cuts through the greenwash by analyzing company-level and product-level data and accounting for six interconnected environmental footprints and real reviews. Instead of just saying one product is more “sustainable” than another, we simplify the science, category by category. No jargon, no blanket claims or wishy-washy statements.
