At HOLY our vision is to become the most loved soft drink brand of the 21st century. Traditionally, soft drinks fall into two categories: popular brands that are tasty but unhealthy, whereas those with a strong health focus usually lack great taste. At HOLY, we break the status quo.

Since launching HOLY from our living room in 2021, we have built a loyal customer base of 2 Million+ across Europe and scaled profitably to more than €150m+ in sales, with a category-leading 4.6-star rating on Trustpilot and reviews.io. And that’s just the beginning: Backed by the world’s leading consumer investors, our team of 150+ aims to disrupt the soft drink industry while creating a product and brand consumers truly love. To join us in this mission and lets discuss how we can build a global consumer rocket ship together! 🚀

KatKin goes hardcore for cat health: cutting the fluff, thinking fresh and channelling hardcore love into industry-wide change. We put cats over profits, and science over cheap marketing wins. We do things the right way, even if that means the hard way. So cats live long and cat parents can love hard without compromise. We’ll keep pushing until hardcore love is the standard for cat care everywhere. So cats jump higher, zoomie faster, purr louder and live longer. #LoveHard
