Our values


Small businesses don’t typically have access to sophisticated marketing resources and seasoned talent. Sumner & Co. make that possible. Marie and her team have a wealth of global marketing experience – and now that’s available to you.


Everything we do is with our clients’ best interests at heart. We never overcharge. We always start with the basics to make sure we’re a good fit. We don’t work with directly competing clients. We pride ourselves on being genuine, honest people with a true interest in the success of your business.


We’re affordable, not cheap. We offer value for money that's hard to find. We don’t charge typical agency rates and we won’t treat you like a typical agency client. We immerse ourselves in your business and provide the same value that you’d get from your own in-house marketing team. All this for a fraction of the cost - and none of the HR.


We come from the corporate world, but we don’t have corporate restrictions. We’re readily available, we’re easy to talk to and we always go the extra mile. We want you to treat us like members of your team. You can ask us anything and we’ll always offer you the best advice - as if your business was our own.


Who we work with

Unfortunately we can’t work with everybody. We are a small team, so we limit the number of clients we partner with to ensure that each and every business gets the focus it needs for lasting results.

To ensure we deliver only the best experience to our clients, we prefer to work with businesses whose industries align with our team’s experience and expertise.

Developers, surveyors,  sales and rental agencies, management firms, contractors, investment companies, consultancies

Financial advisers, wealth managers, investment companies, lenders, asset managers, insurance firms, auditors, private equity, M&A

Law firms, accountants, recruitment agencies, management consultants, education providers, healthcare facilities 

We don’t just work with companies. If you’re an individual working within one of these sectors, we can help you too.
