Remote Team

At Sigma Digital we pride ourselves in leading the way in Digital Agency Innovation. In 2016 we transformed the business into a remote working agency, providing our team the flexibility to work from anywhere in the World. Our team have fully embraced this model and use this opportunity to fulfil their dreams of traveling the globe while working.

Using industry leading project management and communications software our team have increase productivity removing the distractions of office working.

So how is that an advantage to you, our client? Well with a remote team, Sigma Digital is not restricted to the local talent pool. With our company structure, we can hand select the most skilled experts from anywhere in the World.

Another great bonus to having remote team working is that we don’t have the huge overheads like most agencies, meaning we deliver much more value for money. When you work with us over an agency who pay tens of thousands per month for office rent as well as office bills and office supplies, we have more of your budget to spend where it really matters… your marketing!
