NCB Agency

NCB Agency is a growth consultancy for established businesses that have customers but are not growing as expected. Working with clinics, service providers, workshops and online shops in Portugal and Brazil, NCB helps identify where potential customers are being lost—from advertising and website visits to enquiries, sales and repeat purchases. Its approach, called NCB Growth Intelligence, brings together data from across the customer journey to pinpoint what is limiting growth and decide what to address first.

The engagement begins with a free, no-obligation 20-minute conversation. Businesses can then commission a paid diagnostic, with the scope and price agreed in advance, to receive findings and a prioritized action plan. Implementation and ongoing monitoring are available through a separate proposal, but are optional. NCB also offers a free three-minute self-assessment for businesses seeking an initial view of possible issues. Founded by Natalia Castello, a specialist in digital advertising and growth, the agency draws on years of experience managing digital campaigns and looks beyond advertising alone to include customer service, sales processes and existing customer relationships.
