Using AI-driven analysis of real sales activity, we diagnose what’s actually happening and rebuild the commercial system to make performance repeatable in weeks, not quarters. Operator-led, hands-on, and focused on execution, not theory.

Gregory has been enormously helpful to steer the business to the right direction. In a short session with him, he sees the problem with the business and identify bottlenecks - and tell you the problem upfront.
Appreciate the honesty and directness, it's much needed in the industry.

Gergory gave me some great insight and reccomendations for improving my GTM

Resposta da Greg Mccallum - ThinkWork
I had three advisory sessions with Greg through the eDEAL programme, and they were genuinely invaluable.
Greg combines encouragement with very clear, practical commercial thinking. He helped me sharpen my positioning, sense-check my business foundations, and approach sales and retainers with much more confidence and discipline. The guidance was not theoretical: it was grounded, actionable, and immediately applicable.
I would highly recommend Greg to founders or solo operators who want honest, commercially focused guidance without fluff.
Gregory took the time to really listen and gave thoughtful, honest feedback. It was clear that he genuinely cared, and I truly appreciated his respectful and supportive approach. I’m very glad I had the opportunity to speak with him.

The confidence you gave me is immense.
Shows me a side which I didn't think of.

I found the mentoring to be really insightful and practical. Direct off the cuff feedback is invaluable to have someone 'tell it as it is' to really make you think!
Thanks so much for such an impactful session!
Greg was super knowledgable in all areas associated with our project and challenges. He is firm but fair and very educational.
The advice that he gave will be invaluable as we move forward with our project. There is no question that he saved us money and more than likely made us money too!
Gregory gave me some excellent advice on how to grow my budding business. He asked me some candid questions and made me completely reconsider my approach - I realise now that I was going down a dead end! His style is direct, but also positive and empowering. I would strongly recommend Gregory's services.

Greg was to the point and gave us insights from his experience that changes our perspective of our direction which was humbling but essential. His knowledge of the startup industry, specifically around attracting investment is to the point.

Greg is phenomenal! Gave us 2 sessions that were life changing for Eight (our business).

Gregory’s advice was incredibly helpful especially around how to market my business in the early stages without spending much. He emphasized the importance of focusing on building a community that truly resonates with my brand message. That reminder to stay intentional and clear on the “why” behind the brand really stuck with me.

My conversation with Greg was immensely helpful. Being able to speak with someone who not only understands but has been in the same place and is as open to share his insights and advice the way he did was amazing.
As soon as we are able I'll definitely be looking to have more conversations with Greg!

Resposta da Greg Mccallum - ThinkWork
Before meeting Gregory, I took advice from friends and family which was great, but they lacked in depth business knowledge and experience. Gregory is a super friendly, approachable person, while providing a no-nonsense approach. His business knowledge and insights were second to none and the whole session was simply amazing. I now have a load of action points to improve my business plan and can start seeking funding. Thank you so much for your valuable time and I look forward to our next sessions at the end of January. Additionally the follow-up notes and action points are also extremely useful! It comes to no surprise that I highly recommend you get in touch with Gregory if you want to take your business to the next level!

Very refreshing feedback and advice from Greg, who was very helpful and direct. I found him honest and to the point, especially considering we only had an hour, he was able to guide me to some important realisations.
Honest, real, and useful feedback - thank you Greg!
Greg was down to earth and is clearly an expert in his field. He understood the issues that are needed to be dealt with at this early stage of the business concept
