Sidekick offers facilities management and cleaning services to businesses. It was founded in 2003 by Angela Vohmann and her mother, Maureen Bidwell. Over the years, the company has experienced significant growth and currently employs more than 600 “sidekicks”. Sidekick now has a diverse array of clients, including large corporate brands and public institutions such as the NHS, River Island, and The Office Group, as well as small single-site workplaces. The company’s approach is centred around the concept of marginal gains theory—the idea that improving performance by small amounts across different areas leads to oversized impact.
