We’re Officially Rebranding from Kartesiae to Katsaya

Saturday, October 11, 2025
We are excited to announce that Kartesiae has officially rebranded to Katsaya — a name that better represents our values, our vision, and our closeness to the people we create for.
The name Katsaya originates from the Malay phrase “Kat saya” which translates to “with me” or “belongs to me.” This meaning perfectly captures the essence of what we aim to build — experiences, products, and ideas that feel personal, approachable, and truly yours.
Our rebranding to Katsaya reflects more than a new name; it’s a reaffirmation of our belief that technology and creativity should always feel human. It’s about staying close to you — being right there with you — as you work, create, and grow.
Through this transition, our mission remains the same: to design thoughtful, seamless experiences that empower people to do more, feel inspired, and stay connected.
Katsaya is not just who we are now — it’s who we’ve always wanted to become. Thank you for being part of our journey. We’re deeply grateful for your trust and can’t wait to welcome you into this new chapter, together, under the name Katsaya.
