Great No BS consult
WOW, in one hour Gregory said it as it is for my business formulae and structure. I joined the call knowing that I needed to make changes and I left the call with clarity and options for moving forwards with my business.
If you are considering a call with Gregory, no procrastination is necessary, go for it!
Thank you Gregory for your directness, for making the time to really listen and give me space to share, and for your constructive No BS way of viewing the next steps for Divine CEO magazine.
Great experience
Great experience! Thanks to Gregory's vast knowledge and expertise, we were able to identify the best way forward in our startup journey. Highly recommended!
Valuable and to the point!
It was only an hour-long session, but packed with valuable insights and actionable advice. He highlighted what’s important for us to focus on right now, rather than getting sidetracked by the wrong things. The best part? He gave us clear, practical steps we can take immediately to make progress—no vagueness, just real, actionable advice.
Initial Chat
Had a great initial chat Greg - he listened very carefully, got the idea quickly, and gave very helpful and relevant feedback. Hope to do more together in the future!

Success needs reality checks
I cannot emphasise enough how much value you will get from speaking to Greg - especially considering his experience and generosity. Speaking to Greg was easy and enjoyable. I found the honesty and interrogation of the idea valuable because it forces you to think about what target users are looking for and whether they'd even use it. He offered me steps to approach the idea before investing too much time or money into it, essentially protecting your interests while still pursuing it. I felt he was genuinely interested in giving the best advice, even if it wasn't something you wanted to hear - a reality check. Thank you, Greg!
No nonsense advice
Gregory understood the issue immediately and gave me no nonsense advice
Supportive and helpful
Useful, honest, "tough love" style of advice that helped us reframe our thinking. We're a small startup with limited sales experience and picked up some great ideas and advice in such a short time - many thanks!
Great advice, super insightful
Myself and my business partner spoke with Greg today, he listened to us, asked great questions and made us rethink our immediate priorities. We're at a vital stage in our business, pre-launch, going for investment and Greg managed to touch on all these points, providing valuable insights and assisting us with our clear immediate goals to get where we want and need to be in the short term and that was so so useful. It was great to meet and speak with Greg and really hope to speak with him again in the future. His advice was extremely useful, we have left the call with fresh ideas and feeling super motivated and appreciative for Greg's time and advice. We would recommend anyone speaking with Greg, he is insightful and it has been an extremely valuable hour of our week. Thank you Greg for your time.
The Goldilocks Guide
Greg's advice struck the perfect tone for me. He's extremely knowledgeable, but doesn't shove it in your face. He provides really well-tailored advice, personalised for each business, because he knows there's no one trick to success. Most importantly, he showed me where my mindset was wrong without condescending. Hats off to Greg and can't thank him enough for his time and his advice on next steps.
Good advice packed into an hour that flew by!
Greg's great - went from bumping into him at a couple events to finally getting on a call and talking shop. Lots of value on the all, but also a big tip I knew deep down but had not actioned on yet.
Talking VERY specifically to my ideal client. I was still too broad in a lot of my language - and needed to do better to let people know who I help and what exactly I help them with.
Sounds obvious, but when you;re doing a lot of little things - it's easy to fall back on broad strokes to cover bases before moving onto the next task!
Constructive challenge leading to positive change
I had an incredibly productive session with Gregory Mccallum. His expertise in sales and marketing, combined with a genuine passion for democratising access to business information, made our meeting invaluable. He provided clear, actionable advice on streamlining my business, whilst challenging me to identify the focus of my business going forward.
Throughout our discussion, he encouraged me to simplify and define my company's mission and values, bringing more clarity and direction to my work. Gregory is a phenomenal advisor whose holistic approach and constructive challenge is already having a positive impact on my business.
No bull and plenty of value
Greg went the extra mile to learn about our company in advance. I found his questions just as helpful and interesting as his suggestions and answers. His questions and advice was pointed, but never blunt. Certainly no bulls*** but many takeaways that me and my co-founder will be discussing in detail in the coming days and weeks.
Lives up to his name
Lives up to his name, non nonsense, straight to the point. Actionable advice and practical next steps.
Specific quality advice
Greg has the experience, the diligence and interest to give quality advice based on your situation. He spent the majority of the session asking questions to make sure he understood my situation, and then explained what changes he would make concretely.
Great session with Greg
Great session with Greg, providing insights, benchmarks and expertise on product and sales.
Get clarity and empower decisions with Greg!
I thoroughly enjoyed my conversation with Greg. His pragmatic framework for tackling challenges and making key decisions, paired with his no-nonsense approach, is truly invaluable. If you ever find yourself in doubt or seeking a second opinion, I highly recommend reaching out to Greg.
Really helpful and insightful advice
I signed up for a free consult as I am at a pivotal stage with my business, and as a creative, I have great 'big' ideas, but find the smaller stuff harder.
Greg helped me to understand which key areas to focus on, and helped me identify short and long term priorities, as well as some helpful re-frames about some challenges...
Highly reccomended.
