How Anthony Pierri Turned Thought Leadership into a High-Growth Agency

Most founders think about growth in terms of sales calls, fundraising decks, or paid ads, but Anthony Pierri, co-founder of FletchPMM and a featured speaker at the Startup Mountain Summit, took a different approach. He built his product marketing agency to $1.3M in annual revenue almost entirely through authentic thought leadership on LinkedIn.

Anthony’s path to entrepreneurship wasn’t a straight line. He originally planned to become a high school English teacher. Life, however, led him to a master’s in theology and 11 years as a pastor, where he led services and managed teams of over 75 volunteers. That experience taught him how to build community, guide people, and clearly communicate complex ideas, skills that later become central to his work with startups.

Today, Anthony co-leads FletchPMM, a product marketing agency that has helped 400+ B2B software companies find their ideal positioning strategy and bring it to life on newly crafted homepages. Their mission is simple: fixing confusing positioning.

FletchPMM is laser-focused on helping SaaS startups clearly communicate their value and stand out in crowded markets.

Anthony and his co-founder Robert Kaminski have grown FletchPMM almost entirely through LinkedIn thought leadership. They post 3–4 times weekly with actionable frameworks, opinions, and insights. After building a combined audience of over 130,000 followers, Linkedin has quickly become their biggest lead generator. Now, Anthony claims that 95% of their clients come inbound through LinkedIn (Founderoo), reaching 11–12 million people annually, without spending a dime on ads.

Their approach is built on a “Give First” philosophy: share insights for free, then sell the implementation. By generously providing guidance, they establish trust, authority, and community before any contract is signed. This mirrors the philosophy of Brad Feld, this year’s Startup Mountain Summit keynote, whose “Give First” movement has inspired entrepreneurs worldwide. Anthony is someone who knows how to build community, both online and offline, by providing real value first.

Anthony doesn’t solely speak about building communities; he lives it. His rock band has over 110,000 monthly Spotify listeners, proof that he understands how to create authentic engagement and connect with an audience, skills he brings to every FletchPMM client project. 

Arts, humanities, and creative pursuits are often overlooked in entrepreneurship, yet they foster exactly the kind of skills innovators need: problem-solving, adaptability, and creative thinking. Anthony’s own career; spanning music, teaching, and ministry, demonstrates the power of a well-rounded approach. 

He’s not alone at the Summit in this regard. Katie Taylor, another powerhouse founder speaking this year, holds a PhD in Philosophy. Her background illustrates how diverse, humanistic training equips founders to solve complex problems and innovate in ways that technical training sometimes misses. Together, speakers like Anthony and Katie show that creativity and critical thinking are just as vital to entrepreneurship as business acumen. 

At the Startup Mountain Summit 2025, Anthony will not just share frameworks and insights, he will review attendees’ webpages live in real time, giving direct, actionable feedback on positioning, messaging, and homepage clarity. If you’re an early-stage founder looking to refine your positioning, scale your influence, or learn how to give first while growing your business, this interactive session will provide immediate takeaways you can implement the moment you leave the room.
