We believe in better

Over the past 10 years, we've seen an explosion of opportunities for businesses in online retail: from new advertising channels with billions of hours of attention daily to new and growing online sales channels, such as Amazon, Sephora, Walmart and beyond.

... and measurement, for the most part, just hasn't kept up. Because of this, brands aren't capitalizing on these incredible opportunities to both generate demand for their products and convert customers because their systems of measurement don't support them.

It's our mission to change that. We've built the most comprehensive measurement solution for online retail: always on, as focused on upper funnel as it is on lower funnel and across sales channels. With Fospha, brands have the confidence to spend their full-funnel budgets and drive long-term profitable growth.
