Office
Ambitious businesses should be built to carry their own growth.
Marianna Costa is an international business advisory working primarily across wellness, beauty, fashion and hospitality.
We work closely with founders and leadership teams at moments when the business is changing — growing, restructuring, evolving or preparing for what comes next.
Our role is to understand what is happening, provide a senior outside view and help put the right structure, people or expertise behind the next stage.
Our work sits between strategy and execution.
We look at how the business works as a whole: its structure, people, priorities, systems, outside partners and the decisions connecting them.
Ambition changes businesses.
The systems that helped a company reach one stage are not necessarily the systems that will carry it into the next.
Founders find themselves involved in decisions they should no longer need to own.
The instinct can be to add more.
We often start somewhere else.
What can become clearer?
A bigger business is not necessarily a healthier one.
It should not leave a founder carrying every decision, a team unsure where responsibility sits, or an organisation maintaining systems simply because they used to work.
So as the company grows, the structure, people and way of working can grow with it.
Our job is not to make a client dependent on us.
Senior involvement from beginning to end.
Every Marianna Costa engagement has senior involvement from beginning to end.
That does not mean one person does everything. It means senior judgement remains close to the work while a dedicated engagement lead keeps communication and delivery moving.
We keep our core structure deliberately tight. Where specialist expertise is required, we bring the right people into the project — from an international network built across business, operations, technology, creative, digital, production, hospitality and specialist professional services.
The office is new.
The experience behind it isn’t.
Marianna Costa was established in Estonia in 2026, built on more than 13 years of international founder-side experience.
Today, that experience is supported by a carefully selected core team and an international network of specialists brought into each assignment when required.
We remain intentionally close to every engagement.
