FOUNDER NOTE

A Note from the Founders

JAAN Studio exists because we got tired of watching premium brands do all the right things and still not move.

Not because the people were bad, or the work lacked taste. Because ownership was split.

Usually, strategy lives with a Branding Agency, the site is built by a separate Web Design Agency, and Performance Marketing sits downstream. When performance dips, there is always a reason, never a single owner.

JAAN is our answer to the fragmented agency model. We are a Luxury Marketing Agency where taste and commercial discipline sit together, and where the work is built to perform, not just to present.

One plan. One standard. One owner.

The JAAN Philosophy: Integrated Brand & Growth

JAAN comes from the first two letters of our names: Ja (Jake) and An (Antonia).

Later, we realised it also means “soul”, which felt right. The best brands are built on Brand Identity, consistency, and decision-making that holds under pressure.

We kept seeing brands hire parts and call it “full service”. A Brand Studio writes the strategy. Design gets commissioned separately. A site gets built. Then marketing is left to pull it together afterwards.

JAAN is our answer to that. It only works when taste and commercial discipline sit together under one roof. Not as a handover. As one system.
