About Us

About Us

We offer multi-cultural / lingual business process outsourcing and customer support services from Lisbon, Portugal. Lisbon is considered the most beautiful capital in Europe. We believe that language skills alone are not enough for successful outsourcing operations. Cultural affinity is equally important. CLUSTER Outsourcing Services Limited provides a full range of customer contact services, including customer care, technical support, outbound and inbound sales, and payment solutions. Through both human and digital approaches, we help our clients reduce costs, enable scale and drive revenue growth.

CLUSTER consistently delivers meaningful business outcomes and orchestrates exceptional experiences for our clients. Our ability to scale rapidly and provide tailored, industry-specific solutions across functions and geographies has enabled us to drive significant ROI for our clients through the years.

With over 25 years of experience across sectors, we leverage leading practices across many solutions to help our clients accelerate business innovation.
