Testimonials

GSD was excellent. We were new to AI integration, and GSD exceeded our expectations. They got us started on a new journey and we are greatful.

Christian is a visionary in the AI space. He doesn’t just understand the technology — he knows how to translate it into real-world results. Working with him was a game-changer.

Christian and his team were great to work with! We built a few tools for Smalls that have drastically improved efficiency and have inspired the team to think about AI in a new way.

My friend @curious_vii is one of the most thoughtful experimenters and implementers of AI that I know...

Christian was the initiator and key driver behind transformation of how we do product & business management at Arterys. By diligently and patiently helping the organization understand and adopt OKRs as a central tool throughout all the departments at Arterys he has made Arterys a better startup.

Christian has a great way of presenting seemingly complex tools to all levels of AI users. His live demo "cooking show" allowed participants to see in real time how to build a Linkedin profile and posts in real time using multiple sources of personalized AI tools. Run, don't walk, to sign up for any opportunity to learn from Christian.

We embedded GSD at Work in our data analytics and product research work streams and saw huge efficiency gains. Being able to automate repetitive tasks and develop agentic workflows for analyzing data and extracting insights has helped us move from data collection to working with the Product team on implementing solutions much more quickly.

Just a phenomenal teacher, coach, and all around person. Christian taught us almost all we know about setting and managing throughout the OKRs lifecycle and we've seen a drastic positive impact at the company since he came in to work with us. And some little nuggets he shared with me have stuck and resonated even beyond work. Could not recommend him more highly.

I gained a much deeper appreciation for - and got real-time practice using - a range of AI tools to help me extract and make explicit my tacit knowledge. I don't know how long it would have taken me to get this information exposed, in ways that let me translate it into code right away. It's an immense value-add. I have already used some of the tools you showed me to record and synthesize my thinking, allowing me to automate it.

The use of the Claude AI tool helped me sort through a large amount of data and develop a draft report that I was able to finalize in about 25% of the time it would normally take me. Being able to ask Claude thoughtful and specific questions and get succinct responses back was most valuable. Christian's coaching, patience and encouragement as I tested AI in different ways made increased my confidence and made the use of AI more intuitive.

We started our engagement with Christian lacking any real knowledge of how to utilize AI. Rather than jump into specific programs, he helped identify our pain points as an organization and proceeded to show us how AI could help improve or fix them. He followed that up by offering appropriate ideas/connections for implementation which we have since done. If you are just entering your AI journey, I would highly encourage a conversation with Christian because he can definitely get you on the right track!

Christian has a strong ability to take a broad opportunity and turn it into a focused, executable scope of work. On our AI project, he helped us keep the end goal in mind, work backward from the outcome we wanted, and stay focused on delivering value. He not only delivered the project, but also upskilled our team along the way so we could become self-sufficient. I especially value Christian's ability to collaborate, manage scope, and execute; while helping teams understand the "why" behind the "what." He is someone I trust to turn technology opportunities into meaningful business outcomes.

Ever since I learned AI, I've been so productive. I use it every single day, and I'm teaching everyone at my company to use it. I was talking to a guy the other day and I said, “When you're taking meeting minutes, just simply record the Teams.” I gave him a tool to transcribe it and then use AI to pull out the meeting minutes and the action items, and that's going to free up so much of his time. These are some stats that are pretty staggering: It took me five years to get to 36% complete [in writing Rainey's book]. [After learning how to use AI during the workshop] It took me a month to finish it and get to 100. Like where was Jerry [Rainey's AI assistant] five years ago? Just imagine how far I could be if I had this five years ago when I started.

I'm very happy with the way things went over the last three months. You helped us build a prototype in rapid form, you helped us shape the message, you were very good in front of customers. [The most surprising thing was] how fast you came up with the prototype. I thought it would take a week. You did it in like a day, if that. Three hours. You've really opened my eyes to what's possible when you reduce the time-to-capability side of the equation. That surprised me the most. Are you a product or service person? One thing I recognized about you out of the hundreds of people I've worked with since starting Colvin Run, is you're the most ambiguous person on that kind of axis that I've ever met. That's a good thing. As services and product are merging, you're at the tip of that spear.

Working with Christian in our bi-weekly AI sessions has been eye-opening. He helped me cut through the AI hype and focus on what actually matters for our business. Together, we found practical ways to use AI for things we were struggling with - from sorting through all the information flowing across our teams to streamlining our annual reviews and creating better SOPs. What really stood out was how he helped us think differently about our everyday challenges. Instead of getting lost in technical jargon, Christian showed us concrete ways to save time and work smarter. Our brainstorming sessions became more productive, and we started getting real insights from our business data that we could actually use. I got back hours of my time and finally feel like we're using AI in ways that make sense for us. Christian's guidance is invaluable if you're trying to figure out how AI fits into your business. He meets you where you are and helps you build solutions that work for your specific needs.

Christian Ulstrup is nothing short of a publishing powerhouse. From the very first conversation, he brought a rare combination of insight, expertise, and dedication that transformed my book from a mere idea into a fully realized, published work. His ability to take a concept from 0 to 1—guiding it through every stage of development, refinement, and publication—was truly remarkable. What truly set Christian apart was his innovative approach to integrating AI into the creative process. He not only trained me to leverage AI tools effectively but also showed me how to use them to streamline research, enhance storytelling, and accelerate content development. His expertise made the entire journey smoother, faster, and more efficient, allowing me to focus on the heart of my message while technology handled the heavy lifting. Christian doesn't just help bring books to life—he empowers authors with cutting-edge strategies to make the process seamless and successful. If you're looking for someone who can turn your vision into a published reality while equipping you with the tools to do it smarter and faster, Christian is the expert you need. I couldn’t have done it without him!

Christian Ulstrup brought an exceptional level of expertise, energy, and practicality to the HR Leaders Programme. His deep knowledge of AI, combined with his ability to "cook up" real-life solutions on the spot, made every session highly engaging and immediately relevant to senior HR leaders. Rather than discussing AI in theory, Christian demonstrated how today's AI tools can be applied to solve real workplace challenges, helping participants reimagine the future of HR with confidence and creativity. His live demonstrations and practical examples consistently left participants amazed by what was possible, while equipping them with ideas they could readily apply in their own organisations. The feedback from our participants has been overwhelmingly positive. Many shared that Christian's sessions were among the most impactful in the programme and that they walked away with valuable insights, practical skills, and a renewed perspective on leveraging AI to drive business and people outcomes. Christian is an outstanding speaker who has the rare ability to make complex AI concepts accessible, actionable, and inspiring. It has been a privilege to have him as part of the HR Leaders Programme, and I would highly recommend him to any organisation looking to accelerate AI adoption through practical, hands-on learning.

Our project involved helping a senior government IT leader implement a large and highly complex technology and organization transformation effort in his agency. The work entailed conducting several high-level strategy sessions with the leader and members with his senior leadership team. Christian helped us implement AI technology that resulted in improving our efficiency in the planning and executing of our services by at least 50%. In addition, our successful use of AI technology was clearly noticed and recognized by our client, which led to us being awarded additional follow on work. The AI area of automation that we found most valuable was creating a bot that effectively "interviewed" members of the senior leadership team with pre-prepared questions and collected and synthesized the date for us prior to us conducting strategic planning sessions with the team. That resulted in significant increase in our efficiency in the planning and executing of the sessions. Also, AI was able to analyze the team's input and make recommendations that were far superior to what we would have been able to come up with without the AI technology. In addition to the client's increased confidence in the quality of our work as a result of utilizing AI technology, we were able to complete our project in 50% faster. That enabled us to actually perform additional services that were above and beyond the original scope of the project.
