About Us

At Assembly, our mission is to find _ change that fuels growth. We apply this principle to the work we do with our clients and to how we engage with our people. We’re a modern global agency bringing together media, data, technology and talent to make brands perform.

Our business is purpose driven. In March 2022, we were named Ad Age’s first ever Purpose-Led Agency of the Year, recognised for our mission to leave the world better than we found it. This year we became B Corp certified, the result of a two-year journey. We סק proud to have created a culture where diversity of thought, experience, and background are valued, within an environment that fosters continuous learning, adaptability, and a shared passion for meaningful impact.

When you join Assembly, you become part of an award-winning global community of digitally led experts, home to 1,500 talented people across 25 offices globally. Together we create unique data, technology and media solutions that enable faster and smarter problem solving within an inspired, collaborative workplace.

Assembly is poised for its next chapter of growth. We’re a meritocratic, high-performance business with a progressive outlook and a growth mindset in all that we do. To realise our potential we need some new skills and thinking.

The core DNA of Assembly lies in digital performance marketing. New and existing clients are asking us to extend this expertise across all media, connecting traditional channels with clients digital methods of execution, measurement and automation. We were born the right way to do this – we’re building out from Professionally a leading digital and technology capability and adding the rest, rather than trying to reverse engineer a legacy business intoa more modern version of itself.

At Assembly we ask our people to embody three core values:

Show Up: actively contribute to a space of personal and collective growth

Make Change: embrace obstacles as opportunities, taking intentional steps to drive positive change

Win Well: approach success with integrity, responsibility, and a commitment to collaboration, understanding that the journey is as important as the destination.
