Our workshop environment

A relaxed setting away from business pressures and distractions

Simulthink offers a comfortable and relaxed working environment for business owners and leaders to get away from the interruptions and distractions and truly focus on their business strategy and plans.

Business owners and leaders constantly find themselves caught up in the operational and day to day. That is completely understandable. Small business owners typically have to be a jack of all trades. Customers, marketing, sales, products, services, systems, processes, human resources, financial, technology, communications don’t wait. They all have to be managed by someone – and usually there is no department to do it. Just the owner or business leader and a hand full of staff. No wonder one of the major pitfalls for business owners is failing to take the time out from operations to think and act strategically or do some business planning. Somehow, business leaders need to find the time to do both – the strategic planning and the operational.
