Andy O'Neil
Andy O'Neil
Weblytica, United States
My name is Andy O'Neil, and I help entrepreneurs add time-saving automation to their businesses through a process called co-building. This is a 1-on-1 process where I assist business owners in building automations over Zoom calls. Each session is personalized to meet the specific needs of the business owner and their business automation requirements. I have been creating no-code processes and automations since 2006, even before the term "no-code" was widely used. I have a passion for teaching entrepreneurs how to automate their businesses using Make.com, which is why I focus on co-building. My goal is to empower people to understand and control the automation processes in their businesses. I have been married for 21 years and have four beautiful children who keep my wife and me very busy.
