I am Professor of Entrepreneurship at Elon University, where I developed and lead the entrepreneurship and innovation program. My teaching has earned national acclaim, including for my course Creativity & the Doer/Maker Mindset. My research on entrepreneurial thinking is published in Entrepreneurship Theory & Practice, Small Business Economics, and Applied Psychology, among others.
I have also founded, raised millions in funding for, and run two high-growth startups. My first venture was acquired by a Fortune 500 company when I was 27 years old, where I was promoted to Managing Director by age 30. My second startup was a respectable fail — a badge of honor that has given me tremendous insight as a startup advisor and teacher.
On my path to North Carolina, I have lived and worked in Los Angeles, Atlanta, New York City, Orlando, Rio de Janeiro, and Dublin. Along the way, I've written a short novel and recorded songs for an original album, practiced martial arts and yoga, paddled the Amazon River and hang-glided the Swiss Alps, and built Habitat for Humanity homes in four states. Most of all, I am a devoted husband, joyful dad, and grateful son.
I started coaching and consulting when former students wanted to keep working with me as they started ambitious careers, explored innovative opportunities, embarked on marriage and parenthood, or navigated the complexities that come with it all. I look forward to meeting you and helping you craft your best life.
I'm usually VERY skeptical of "online coaches", but I also know what Dr. McMahon did for me so I have had to re-think my skepticism. That's why I wanted to write this testimonial. To you, Sean might be a guy on the Internet, but to me he is someone who changed my path in life.
I first met Dr. McMahon as a freshman in college. I was the furthest thing from a bookworm, but I could tell his insights extended beyond academics, so I decided to visit his office hours and ask him "life" questions. These conversations, covering academics, personal growth, and even relationships, truly changed how I saw and interacted with the world. This was 10 years ago.
Since then, Dr. McMahon's continued mentorship has helped me forge a unique career path and lifestyle that excites me. For instance, a year after college Dr McMahon's input sparked a career shift from business to data science. Later, after almost 6 years working at a large firm, Sean coached me as I started my own LLC, beginning an entrepreneurial path of my own.
I am 30 now and feel like I am living my dream - happily married and doing a job I love. I'm not sure how my life would have turned out if I didn't meet Dr. McMahon, but it certainly would not be here.
Sean McMahon has spent his life getting to know the startup world inside and out- and it shows the moment you start talking to him. He's not just smart about it, he lives it. He's constantly reading, asking questions, trying new things, and learning from every angle. It's clear he loves doing this.
And he's been through it himself, more than once. He's built, pivoted, failed, and kept going- all of it. So when Sean gives advice, it doesn't come from a textbook. It comes from real life. He knows what the pressure feels like, and that makes his perspective incredibly grounding.
As an early-stage founder, working with Sean was a turning point for us. He helped us zoom out and reconnect with the bigger picture, while also making sure we were laser-focused on what we needed to do this week. He asked the hard questions- Why are you building this? Who exactly is it for?- and didn't let us move on until we had real answers.
He has this way of helping you cut through the noise. Every time we talked, we'd walk away with more clarity- not just about what to do, but what not to worry about. He doesn't let you hide behind busywork. He wants to see you ship.
But honestly, the best part about working with Sean is how much he cares. He really, truly wants you to succeed. He's one of the most respectful, thoughtful people you'll meet in this space- someone who'll challenge you, support you, and keep it real the entire time.
If you get the chance to work with Sean, take it. I can't say it any simpler: our company is better because of him.
Dr. McMahon has a sharp instinct for connecting people with the right opportunities at the right time and a way of revealing possibilities you hadn't yet imagined. Sean was the key driver behind my decision to move across the country to San Antonio — a leap that pushed me completely out of my comfort zone, fundamentally changed the trajectory of my career, and put me far ahead of my peers.
His guidance helped me pursue an entrepreneurial path that has lead me to executive leadership. Today, at 25, I serve as the COO of two companies — something I wouldn't have thought possible just a few years ago.
Sean has a rare gift — not only for mentorship, but for helping unlock clarity, courage, and momentum. His questions and insights can drive you to make bold decisions and ignite a fire within.
Research on leadership and creativity has identified over a dozen leadership constructs that boost employee creativity — but virtually all of them work through a single mechanism: increasing intrinsic motivation. This study introduces a different path. Leader heuristic transfer (LHT) is defined as the conveyance of a leader's experience-based "rules of thumb" — cognitive frameworks for pattern recognition, discovery, and problem solving that employees can adapt to their own challenges. Think of Warren Buffett's protégés, all trained by Benjamin Graham, who each credited Graham's cognitive frameworks (not just his inspiration) as the foundation for their independent success across different firms and time periods. Using a sample of 289 employee–supervisor–coworker survey triads across diverse industries, the study found that LHT has a significant positive relationship with employee creativity even after controlling for established factors like openness to experience, innovation as a job requirement, and leader intellectual stimulation. Specifically, LHT boosts creativity directly by enhancing ability, with intrinsic motivation as a welcome byproduct rather than the primary mechanism.
Why do some entrepreneurs choose equity crowdfunding over traditional angel or venture capital funding — even when they could secure those more established sources? Prior research largely treated equity crowdfunding as a last resort for discouraged entrepreneurs, explained by pecking order theory and transaction cost models. This study challenges that view. Through an inductive, multiple-case research design analyzing over 1,400 pages of SEC filings, pitch materials, investor Q&A transcripts, and direct entrepreneur interviews across 14 U.S.-based firms, we identified two distinct fund-seeker types: necessity fund-seekers (for whom equity crowdfunding was the only viable option) and strategic fund-seekers (who had access to angels and VCs but chose crowdfunding deliberately). For the strategic fund-seekers — experienced serial entrepreneurs with prior funding, strong networks, and favorable industry positions — the decision was driven by a constellation of factors that rule-based models miss. These include retaining founder control through favorable deal terms, capturing demand-side value from a large base of investor-evangelists, creating market validation information through the crowdfunding process itself, and aligning with external stakeholder values. We propose a contingency-based model of "funding fit" — a perceptual, dynamic framework in which entrepreneurs evaluate which funding source best matches their venture's needs at a given point in time, accounting for value creation and not just value capture or transactional efficiency.
Most entrepreneurship students don't start companies after graduation — yet the field has long measured its success primarily by venture creation and entrepreneurial intent. This study asks a different question: does studying entrepreneurship make you better at your career, even if you never found a startup? Drawing on human capital theory and survey data from 353 alumni across three U.S. universities, we compared early career outcomes of entrepreneurship graduates against a control group with no entrepreneurship coursework. Using structural equation modeling, the analysis found that entrepreneurship education leads to higher levels of entrepreneurial behavior in the workplace — and that these behaviors mediate the development of professional competencies employers prize most, including leadership, work ethic, oral communication, and career management. In turn, those competencies predict professional advancement such as promotions and salary increases. The mediated effect of entrepreneurial behavior suggests that it serves as an "active ingredient" making latent professional skills more salient and actionable. Notably, entrepreneurship alumni reported lower written communication proficiency — an area for curricular improvement. The implications extend well beyond entrepreneurship programs: integrating entrepreneurial behaviors into other disciplines may enhance career readiness for all graduates.
Good question. Never say never, but right now I am not focused on building an empire. I am a successful college professor, technologist, and investor. I am also a happy husband, dad, brother and son in a family that I love to be around.
Through the years I have been approached for advice by more and more professionals and entrepreneurs, but I did not have an organized way to help. Now I do, but I only have a few spots in my calendar. I am being purposefully lean. If you work with me, you will be on a short list of clients so that I can focus on helping you move forward and still live the kind of life I want to live.
If you are at least 18 years old and not a student at Elon University (where I am a professor), then we can work together. However, you have to be ready to do the work.
In my experience only a subset of college students are ready to gain the insight and take the action needed for impactful growth. If you are one of these people you probably know it. Maybe it's just a flicker of something you can't quite put your finger on, but you know you want the growth. If this is you, let's talk.
