ABOUT LAUNCHMETRICS

Launchmetrics is the leading Brand Performance Cloud used by Fashion, Lifestyle and Beauty (FLB) executives to make smarter decisions around their branding efforts. With over a decade of industry expertise, we have helped more than 1,200 customers create inspiring, impactful and measurable experiences. Founded in NYC and with operating headquarters in Paris, we have employees in ten markets worldwide and offer support in five languages.

THE TEAM

We are a team of passionate engineers distributed across the world, always eager to learn new things. We are building state-of-the-art modern applications and scale it on the cloud.

We recently moved our Product and Tech teams to a pod model: A pod is a small group, 1 to 4 people, that owns a single mission end to end: from scoping and building through cleaning, enablement and watching adoption. Pods form around a mission and dissolve when it's done. Everyone is a pod owner, from the most junior person to the most senior, because ownership is the point. Your domain is your product-area home, the part of our software suite you know best. Pods change with every mission; your craft and your domain don't.
