History The company was founded in 1984 as Adder Publishing by Adrian Dickens and was rebranded as Adder Technology in 1986. It relocated to Bar Hill in 2012.
Adder initially developed connectivity solutions before specialising in KVM technologies, expanding internationally and establishing a global distribution network spanning more than 60 countries.
Over the following decades, Adder developed a portfolio of KVM switches, extenders and IP-based solutions used in mission-critical environments including broadcast, post-production, industrial control rooms, transport and medical imaging.
In November 2025, the company transitioned to an Employee-Ownership Trust (EOT), transferring a majority shareholding into a trust for the benefit of employees. The move was intended to support long-term independence and align ownership with employees.
In February 2026, Adder opened a Customer Experience Center (CXC) at its global headquarters in Cambridge, designed to provide an environment for customers to evaluate and validate complex connectivity solutions.
