Overview • Klark

Turn your support team into super heroes.

Klark's mission is to transform the way companies engage with their customers through generative AI technology, building the future of customer care — where generative AI doesn’t replace humans, but gives them superpowers.


From the very beginning, the founders knew they needed more than a smart product: they needed a sharp, confident brand to match their ambition.


We teamed up with Klark from day one to shape their strategic foundation, define their voice, and build a visual identity that feels as intelligent as their tech — but also warm, simple, and deeply human. From logo design and UX writing, every piece of the brand was crafted to reflect their core belief: AI is at its best when it works hand-in-hand with people.

Thanks Guillaume Rouby (ex-CMO, BackMarket) for your warm intro with Klark.


Working with the K was a blast — smart, fast, and seriously ambitious team. They’re cooking up big, and if we were you, we’d grab a seat at the table now.

“From the very first workshops, Sigmoon brought clarity and energy to our project. They helped us shape not only our identity, but also our message — turning abstract ideas into something people instantly understand and connect with.”

“Sigmoon dove deep into our vision, challenged our thinking in the best way, and helped us translate a complex AI product into a brand that feels both sharp and human. The result goes way beyond a logo — it’s the foundation of how we present ourselves to the world.”
