BETNA BETKUM - بيتنا بيتكُم
This means “Our Home is your Home.”
Betna Betkum is more than a welcome. It reflects how we have built Archer. We are genuinely a family — a company founded on trust, respect and looking out for one another. And that extends to our clients too. We don't believe in simply providing a service; we work alongside our clients, become part of their team and build partnerships that last.
OUR STORY STARTED BEFORE ARCHER
Archer officially opened its doors in 2019, but our story began more than a decade earlier. Some of our team first started working together in South Sudan in 2008 — before independence. Over the years, they went on to work across different organisations, roles and locations, building experience through some of the country's most significant periods of change.
When Archer was established, many of those paths came back together. Since then, the family has continued to grow, bringing together South Sudanese and international professionals with experience spanning security, operations, logistics, risk, training, finance, technology and support.
The people featured below are only part of that team. Across South Sudan, our field, operations and roaming teams support clients wherever they are needed — from long-term development and security contracts to emergency response, surge requirements and short-term VIP missions.
