It was extremely helpful and productive to have an advisory session with Greg regarding my early-stage startup, where we discussed the overall product strategy. He stress-tested our decisions and provided valuable insights based on his solid experience, helping me confirm some critical aspects of our strategy and prompting me to reconsider others.
We addressed all the doubts and uncertainties I had at this stage, and next, I will seek advisory assistance from Greg again as we approach the sales processes, given his extensive knowledge in that area too.
Wow. I really have only good things to say about Greg and this service in general.
As an early-stage founder, its very easy to get stuck in the weed of your idea. Greg has the great ability to very quickly absorb a lot of information in order to give you great, really actionable advice.
Greg, thanks again for all the help.

I had a great discussion today with Greg who gave me very valuable pieces of advice and interesting perspectives. He is a great person to bounce ideas with. He is "no BS" and straight to the point, which is exactly what I needed. Highly recommend having a chat with him!

I recommend Gregory for any founders who are looking for unique coaching or advice for their startup. We cut all the BS and got straight to the paint points and root causes of my sales pipeline. Gregory's approach is very strategic and personable, his commercial background resonates through for someone who also comes from a commercial background - i highly enjoyed our conversation and sometimes you just need that extra push!
Really good sounding board and huge value add from just an hours worth, highly encourage founders to take up the pro-bono offer - you won't regret it.

Focus is the key outcome that you would leave with post-meeting with Gregory. He is an expert who knows how to nail it right in just minutes.
I will be coming back to him real soon.

Greg has a keen eye for honing in on the problems at hand and suggesting actionable steps to follow.
You can tell he has real world experience from his previous ventures and not just repeating from a book on business coaching!
I will be speaking with him in the future to arrange some further sessions I'm sure.

In less than 15 minutes, Greg was able to focus me on the type of business I would like to start, organize my thoughts on potential audiences and how to reach out, how to build reputation, and finally when and how to start billing. He also advised on how to do all of this while keeping a full time job still. The experience was fantastic- Greg is very sharp, keeps you focused and doesn't let you be taken by your own fears and blockers. I will 100% get back to him when my soon to start business is ready for the next steps. Thank you Great!

I recently had the privilege of utilising Greg's time, and I must say it was nothing short of brilliant! From the moment the session began, it was abundantly clear that I was in the hands of an expert who genuinely cared about helping me succeed.
The session was scheduled for an hour, and every minute was packed with invaluable insights and actionable advice. No time was wasted as Greg delved into the heart of my commercial challenges. He had the ability to assess my specific situation quickly and provide tailored solutions was nothing short of remarkable - which shows the amount of experience and knowledge he has build up over the years. What truly set our session apart was the perfect blend of practical advice and mindset coaching. It's one thing to receive guidance on immediate actions to take, but it's another to have someone empower you with the right mindset to tackle those actions - and Greg did just that. This left me feeling not only equipped with knowledge but also with the confidence to implement his recommendations. By the end of the session, I had a clear roadmap of steps to take, a newfound sense of determination, and a deep sense of gratitude for Greg's generosity and expertise. I would highly recommended booking a pro-bono session with him.

Gregory was super helpful to us in breaking down what we needed to do, understanding what we're doing and what phase of the process we're in, and our next steps. He did all this in an hour. I couldn't have asked for better advice and the fact that he was a straight shooter really helped too. He doesn't beat around the bush and will let you know what is and isn't viable.

I've talked with a lot of sales coaches and mentors, and often it's a lot of "here is why I'm good". Not with Gregory. We sat together, and he helped me. No fluff. Instant value. Makes me laugh to think how easy it can be, and how complicated people make it.
Genuinely great guy with sober, instantly actionable insights. He'll have a pro bono chat with anyone, so nothing to lose.

We told Greg our current business situation. What we aim to do and what we were struggling to do. He gave us great advice based on his experience but mainly made our vision alot clearer. Would 100% recommend!

Greg was straight to the point and gave me practical skills to sell our SAAS, which I am pleased about. He confirmed my approach and assured me that I am on the right path.

Gregory is easy to talk to and easy to understand. He was quick to grasp the value of my product and could easily relate to some quite technical issues involved in bringing it to market. I learned many things in the free one hour advice session, things that I'm sure will save me a lot of time and stress in the future. So it's five stars from me.

Greg was understanding and supportive, and gave me tangible actions to take away and work on I really enjoyed the session and highly recommend!

Thanks Gregory for showing a genuine interest in trying to help with our sales process and strategy!
Greg gave me really useful, candid advice about the next actionable steps I can take to increase sales at my early stage startup. He was able to cut through the BS and provide clarity on what I should and shouldn't be focusing on.

Réponse de Greg Mccallum - ThinkWork
Gregory is a great guy who listens and asks relevant questions and then gives proper answers to the questions that you might have.
Got some very simple advice, which for some reason, didn't come to my mind before. And I believe that is what great conversation partners do. Open the eyes to the most simple things, that realistically can make a big impact on your current activities.

Greg provided excellent guidance and insights for my startup. His honest, insightful feedback and practical go-to-market strategy plan were invaluable. He provided tailored, constructive, and actionable advice, making our interaction extremely productive. Highly recommend Greg to any startup looking for robust and honest guidance.

When my team member found Greg, I was skeptical about talking to someone I don’t know about my project. However, I am open minded and decided to talk to him about my project. It proved to be a great experience. First of all the conversations flowed very well, and Greg is able to communicate his advise and ideas in a simple and organised fashion. His ideas were useful and his questions helped me to see things from a different prospective. His advise is great, and I can see he is easy to work with.
