Had an excellent session with Mark. We are technical founders and really need a kickstart and insight from someone experienced like Mark. Thanks a lot! Can recommend Mark if you are looking for Marketing or Sales advice and how to get started.

Mark really really knows outreach-based sales. Was great in helping me understand the ins and outs of how to approach my new project as well as common pitfalls. Watch Mark's 2 incredible sessions first, then have a session with him. It'll level you up fast!

Mark is an absolutely amazing outbound specialist. He's helped me to narrow on my ICP really well and has helped me craft what I'm confident will be a high-converting outbound email campaign. There's no one I trust more with outbound prospecting than Mark.

Mark is a true authority on cold outbound. It was one of the most value-packed calls I can remember, running through a huge number of questions both technical and strategic. He was able to answer every and offer proactive ideas...would highly recommend.

Mark was great and it was a really useful session. He totally understood my questions (around B2B SaaS outbound marketing and sales techniques) and answered them directly and comprehensively. He's extremely friendly and approachable - I would recommend him to anyone.

Mark is amazing! We went through a complex outbound prospecting challenge, which he easily broke into affordable and actionable actions. You can see he is analytical and passionate about his trade. I'm now super excited to work on what we discussed during our session.

Just had a blast of a mentor sesh with Mark Colgan, the Jedi Master of list building and cold email wizardry. If you're diving into the wild world of outbound strategies and need a guru who makes complex stuff simple, Mark's your guy. 10/10 would get my mind blown again.

Liked Mark's responsiveness and how we jumped on a call quickly after emailing him. We learned more about cold email, its structure and deliverability and some of the downsides of current tech solutions. For cold email, I'd have no hesitation in recommending Mark Colgan.

Yet another extremely useful call with Mark. What I like most is how he is able to make things simple, reduce issue the essence, and that just makes it so much easier to make decisions and take action. And there's always an eye-opener when I talk to him, so yes: Recommended.

Mark came in and reviewed my cold email copy + approach to booking clients. He shared ways to improve my call to actions, make some of the emails clearer, as well as how to improve the user funnel in booking demos. Most importantly, I left with some solid experiment ideas that I cannot wait to test out.

As a first time founder doing cold calling and demos I struggled to put structure on how to talk on the phone, how to do the demos, creating your pitch and story, etc. Mark was absolutely amazing! He gave me such valuable advice. I now have the structure and confidence to close more deals! Thank you Mark!!

Mark gave SO MUCH helpful advice on how to think about migrating from our current email/communications platform to a new, more robust solution. I was tangled up trying to plan out the migration myself, and Mark made things much simpler with his "Couch to 5k before trying to run a marathon" approach. Thanks a ton, Mark!

I just wanted to share that I had an amazing session with Mark! He was incredibly helpful, supportive, and friendly—and took the time to walk through specific cold outreach strategies tailored to my situation. His insights were exactly what I needed, and I left feeling so much more confident. A huge thank you to Mark for his guidance and patience!

Mark did a fantastic job of really quickly getting to understand the entire Growth Division sales process. He helped us identify several key ways that we could optimize our sales pipeline. This has helped us shorten our sales cycles and allowed us to quickly close deals more deals that are in our pipeline as well as stopping deals becoming stagnant.

If you're an Agency Founder and want better results, then work with with Mark. Like, now. He spent time truly listening and understanding my process for outbound sales and his recommendations. In particular around structure and process, which has had a huge impact on not only keeping me on track and moving prospects forward in the pipeline, but also on closing deals.

Mark brought clarity to some of the strategic moves I was considering, especially around expanding service lines and pricing. The advice was practical, non-generic, and based on real experience—which is rare. I left the session energized, with clear action items and a sharper perspective. Highly recommend if you're looking to level up. — Avinash Haridas, Founder at Precise Leads

Mark was a pleasure to chat with, highly recommend him to anyone looking to learn how to level up their sales approach. Having little sales experience myself, Mark was able to quickly walk me through a number of key ideas and tools to use to make fast improvements and even shared a template for outreach that I'll be able to put to work right away. Most useful 30 minute chat I've had in quite a while.

Mark is an agency sales superstar. Having run and exited his own agency in combination with deep sales training experience, he has the perfect skill set to understand and help agencies close more business. Mark audited our sales process and provided real clarity in how to accelerate our pipeline velocity. We've taken our sales process to the next level and already started closing more deals. Highly recommended!

This is my first booked session on Growthmentor and I am blown away! Mark, thank you so much for your valuable advice. In these exciting 30 minutes, I learned about outbound more than I learned over the past 30 days! Lots of golden nuggets that I wasn't expecting. I'm still warping my head around what I have learned. If possible I'll surely have another call with Mark, It was such an insightful session. Thank You!

Mark keeps things simple by breaking down the process into manageable steps. He taught me that outbound messages aren't just about selling; they're about offering value. With his help, I've learned to approach messages by addressing the problem the recipient might have, offering something of value for free, and sharing case studies to show how I can help. This approach will certainly make my messages more engaging and effective.

Had a great engagement with Mark while working in an eCommerce Agency environment. Mark was extremely adaptable to the personalities he was training, quick to pivot session-to-session; it was clear that he didn't believe in a one size fits all approach, all of the sessions were tailored to the agency. Skills taught by Mark were easily transferrable and produced the results we were looking for. Highly recommend working with Mark!

Mark was an incredible consultant and trainer to work with. 10/10 would recommend! He did a thorough audit of our sales structure, pipeline, and processes followed by personable coaching for our team. We were able to use his findings and expertise to improve our results and close more deals. He also helped our sales team gain confidence in their presentations & communications with prospects. So grateful to have worked with him!

Mark recently delivered a useful workshop to our portfolio companies about how to navigate the recent changes to cold email.   The session was very well received and founders commented on the good balance of strategic and tactical advice.   If you're looking to bring in an expert who can shorten the learning curve, I recommend speaking with Mark. Some of our portfolio companies have subsequently engaged Mark to advise on their email campaigns.

I introduced Mark to one of my clients to help them build out the strategy and messaging of a new outbound sequence in HubSpot. Mark helped them improve their approach to prospecting which has impacted their entire approach to Sales and Marketing. The early results speak for themselves, with some promising sales meetings booked from one campaign already and the team having the skills and confidence they need to replicate these results in the future. 

Mark is among the 2-3 smartest people I know. He is not just extremely knowledgable in the domain of building an agency and selling agency services. He is also a sharp business mentor overall. He helped me tremendously by making the complex simple, reality checking me and providing ideas and solutions to cover my weaknesses. His help had actual ROI. I cannot recommend him enough. This testimonial is 100% my opinion and I had no side benefit to provide it.

Mark recently delivered a couple of workshops to the GYDA community. Covering a range of new business development topics for agency leaders, the feedback has been great and has received the highest feedback rating for external speakers we received to date. Mark delivered fantastic content - no-fluff advice, filled with actionable insight (rather than vague theory) which they were able to implement straight away.  We'll be inviting Mark back for workshops and events in the future.

We worked with Mark to help us improve our outbound campaigns. We felt that whilst we had a solid offer and service, we weren't sure how to approach our ideal customer with the right message.  Mark trained our team on how to approach prospecting in general and also how to write emails that get replies. He also helped us understand how we should build our outbound campaigns to ensure they land in the inbox. We've already generated more replies and meetings than our previous campaigns and we're working with Mark to further improve these results.

Working with Mark was great! He was incredibly helpful in providing constructive feedback, useful tips on progressing deals, and overall guidance on improving my sales skills. I learned so much from Mark. In short, I discovered why focusing on pain points can help close more deals and just how important a positive mindset is in sales. At the start of our engagement, we hadn’t narrowed down our ICP—doing so provided a ton of clarity on who our ICP is and the different personas we speak to. This helped us tailor our conversations. I would absolutely recommend working with Mark! He'll help you build confidence in your sales skills.

I just ended a conference call with Mark, I must say that I am thoroughly impressed with the quality of the conversation and his abilities. The call was excellent in every sense of the word, as he was warm-hearted and insightful throughout the entire discussion. What impressed me the most was his ability to listen actively and understand my business’s unique needs and challenges. He provided some excellent ideas and directions that were helpful in addressing the issues at hand. Mark’s excellent ideas and directions have undoubtedly set me on the path to success, and I couldn't be more grateful for the opportunity to work with him. Thank you.

I originally reached out to Mark because I needed a bit of help understanding how I should build my agency moving forward. Mark was great to talk to because he gave a lot of perspective and guidance based on having been there and done that, which I found very different from the other people that I was talking to because they weren't quite able to guide me in the right direction based on their experience. Mark also provided quite a few actionable steps moving forward. So I left the session knowing exactly what I needed to do and had a very clear vision for the future. So that was super helpful. Many thanks, Mark, and I definitely recommend it.

Mark designed and delivered several Bootcamps for my private training academy for ecommerce agencies - Ecommerce Agency Growth. I specifically requested that each workshop was actionable to enable attendees to implement the recommendations, rather than absorb lots of theory without any output. Many bootcamp attendees and agency owners have been in touch since the bootcamp to express how valuable the insights were. The feedback has been positive with 5/5 and some agencies opting to work directly with Mark to tailor the recommendations to their agency. Mark's teaching style adapts to the level of the attendees and is able to share real-life examples and experiences making it extremely valuable for agencies who are struggling with their outbound sales practice

I was looking to transition my agency business from a fully-done-for-you service to something more focused on consultancy and backend work. The reason for doing so was to get higher profit margins, and only work on the things I enjoy. I worked with Mark as he was a mentor in an exclusive bootcamp that I was a part of. Prior to that, I've watched many of Mark's videos on YouTube and followed him on LinkedIn, so I know he was a credible person. Mark has obviously gone down a similar route like mine, and he was able to clearly articulate what I can expect if I were to make the transition, and having those perspective definitely help me in planning my route ahead. I'm looking forward to many sessions with Mark in the upcoming weeks. If you are also stuck at your current role and looking to get some practical advice on how you can pivot your agency, Mark has been there, and done that, and he can give you great suggestions on how to make the next move or pivot. I would definitely recommend having a chat at least with Mark!
