In-the-moment user feedback for mobile and web apps to unlock growth.

1Flow is building a user engagement layer for all apps on mobile and web to help companies increase conversion and reduce churn at scale – starting with in-product user feedback collection. Our first product is a flexible tech platform to collect in-product user feedback, that directly feeds into product development so you can know why churn and conversion happen, and launch features that will have a direct ROI to a company’s bottom line.
