Coefficient created by Sarah Rossigneux

Coefficient was created in 2008 by Sarah Rossigneux. Whilst running her own restaurants, Sarah became aware of a gap in the market for expert affordable support….

“Restaurant owners and managers are often so busy running their business that they don’t have time to spend on other areas vital for growing the business such as marketing, operations, financial management… This is where Coefficient comes in. We can provide you with those extra services exactly when you need them leaving you time to do what you do best… run the business.”

“What makes us unique is that we charge by the hour or day so you can choose how much and when you want to use us”.

With 20 years experience in the hospitality industry, managing and establishing many successful restaurants, Sarah brings a wealth of experience to the business and has true passion for the service and food industry.

For expert advice and solutions for your restaurant, get in touch today and see how we can help. Initial consultation is free. sarah@coefficientco.com
