Client Testimonials

I help founders, sales leaders, and enterprise sellers move stalled opportunities, strengthen business cases, equip internal champions, and turn pipeline into revenue.

Here’s what clients and sales professionals have said about working with me.

Confiant

Louis-David Mangin, Co-Founder & CEO

“Mark worked with Confiant during an important period when we needed sharper execution around live deals and sales leadership. His coaching and enterprise sales judgment helped our team focus on the right opportunities, clarify next actions, and keep deals moving. He brought practical, direct guidance, challenged our thinking where needed, and left us in a stronger position than he found us.”

Google Security

Carylanne Wolfington, Account Executive

“Mark is an exceptional sales coach. His approach to deal-making is practical and grounded in how enterprise business decisions actually happen. With his help, I’ve taken my sales craft to another level, integrated AI into my process to work smarter, and recently closed one of the biggest deals of my career. He is excellent at helping translate complex challenges and solutions into outcomes that executives can actually act on. Highly recommended working with Mark!”

Google Security

Tyler Morris, Account Executive

“Mark has made an immediate impact. He’s helped me cut through the noise, focus on what executives actually care about, and think more strategically about business conversations. Together, we built a clear plan for my top target account using real buying signals to create and advance opportunities. He also helped me prepare for key executive meetings and pressure-test one of my top deals. Mark’s direct, practical, and highly effective. His sales experience, industry knowledge, and AI expertise would help any sales rep get better fast. I highly recommend working with him.”

Palo Alto Networks

Anthony Aurigemma, VP, Global Alliances

“What I love most about working with Mark is his enthusiasm and his intense desire to create great outcomes for his clients. Particularly with early-stage technologies, Mark is very talented in helping clarify why and how that technology can really propel the client to what they’re trying to accomplish.”

Quintic Labs

Josh Van Dress, Founder & CEO

“After one call with Mark, I learned more than I had from several other conversations. He has a rare ability to quickly zone in on the real issue, give direct, no-sugar-coated advice, and make the time immediately valuable. It was one of the best calls I’ve had in a long time. I’d recommend giving Mark an hour of your time. Worth every penny.”

Verve Industrial

John Livingston, CEO

“Mark has a real emphasis on improvement in performance, which is really key for a consultant.”

Margo

Ben Corrado, Founder & CEO

“Really fun chat with Mark! Wish we had more time to get a bit deeper, but he managed to pack in a ton of valuable insights into a short period of time, particularly highlighting blind spots I had around selling the tech versus selling the outcome.”

IQ Agency

Lauren Berger, Founder & CEO

“Mark is actively helping us change the way we think about our sales organization and structure. His advice is practical, specific, and helps keep deals moving in the right direction.”

Kheiron Technologies

Peter Kecskemethy, CEO

“We’re working with Mark on upgrading our sales processes. Where Mark helps the most is in translating a complicated technology into an economical outcome.”

Vision Board Media

Donna Serdula, Founder & CEO

“Mark’s deal coaching shifted my focus to the business benefits my clients would gain, leading us to collaborate on an exact solution at a mutually agreed-upon price.”

Experio Labs

Daniel Cohen-Dumani, Founder & CEO

“Mark helped me turn a pilot into Experio’s first paid customer. He pressure-tested the offer, sharpened the business case, and coached me through the buyer conversation and follow-up. That win directly triggered a VC investment. Mark doesn’t give generic sales advice. He gets inside live deals and helps founders turn momentum into revenue.”

E3Fold Collective

Jason Zimmerman, Founder & CEO

“When I started working with Mark, sales felt like a mystery and, honestly, a little intimidating. He helped me translate a complex consulting offer into language executives could quickly understand, improve my outreach, and approach real opportunities with more structure and confidence. His coaching was practical enough to apply immediately. In one LinkedIn test, his approach generated 105 new connections versus 35 with mine. More importantly, he taught me how to connect my work to business outcomes, ask better questions, and end conversations with a clear next step. I got exactly the intellectual ROI I was looking for and a much stronger foundation for growing 3Fold.”

Aiden Technologies

Josh Aaron, CEO

“Mark brought valuable enterprise sales experience to Aiden at an important stage of our growth. He helped us adopt MEDDPICC as a more disciplined sales framework, sharpen our thinking around complex enterprise sales cycles, and better connect Aiden’s technical capabilities to customer outcomes, executive priorities, and the business case required to move opportunities forward. I personally benefited from his coaching and perspective, and Aiden came away with several practical practices and frameworks that continue to influence how we sell into large organizations.”

MarketMeMore

Nikki Estes, Co-Founder & CEO

“Working with Mark changed how we evaluate opportunities, partnerships, and value. His guidance helped us sharpen our messaging and assess whether an initiative could increase revenue, reduce cost or risk, and improve performance. In less than four weeks, we applied that thinking to conversations that contributed to three new opportunities in our pipeline and five for one of our clients. Mark helps leaders think more clearly about positioning, business value, and how to move complex deals forward. I’d recommend him to founders and growth leaders working on high-value B2B opportunities.”
