Calum is an absolute legend. He's extremely knowledgeable with insane experience, nothing that he didn't overcome in the past. Listening to him talking is like listening to Steve Jobs! His intelligence is beyond this world and will leave you thinking for weeks after the mentoring session! My experience so far had been nothing but positive and I just wish I came across him earlier. To simply explain what you can expect from him: Imagine you just opened an oil company and you're on a mission to find oil reserve to establish your first operations. Now since you have no experience it can take you a very long time before you even find oil. After years and years of searching you with no success you come across Calum. He is a local and he has the land knowledge and understands the operation. He not only shows you the route which you take to your first oil findings but he tells you the exact tools and machinery you'll need to extrapolate it and provides you with the logistical plan to distribution. Now he saved you time, operational expenses and fuel to get to your first clients. What not to expect He'd not do the work for you so don't expect him to find oil for you. I've founded a successful brand and I own a hospitality company and I've also been bankrupt twice and failed in 7 companies so I've yet got a lot to learn and a long way ahead. I'm now starting all over again from 0 and in a completely different country, with different culture, different regulations, absolutely nothing is the same so I was feeling very lost before I found Callum. He's been nothing but a life saver and I can't speak highly enough about him. I appreciate him and recommend him to anyone that needs guidance in his/her business either it's very established or only a start up, I guarantee that Calum will be able to help you navigate the ship to your desired destination! Best wishes

Calum is an excellent mentor, and even from just one session, it was clear that he comes well-prepared and engaged. He effectively uses practical examples to illustrate complex concepts, making the pitch deck review both informative and understandable. His focused approach in our session truly enhanced the overall experience.
