William RainerUtilizing the network and the mentorship at the University of Alabama at Birmingham J. Frank Barefield Entrepreneurship Program, William Ranier is set to graduate from the Collat School of Business in May as a successful entrepreneur. This January, Rainer launched Aim Ventures LLC, a hybrid marketing firm focused on product launches, startups and brand recognition, with a belief that strong marketing elevates business and strong businesses create strong economies.
Why UAB?
Born in Birmingham, Alabama, Rainer grew up in Fairhope, Alabama, where he fostered values of faith, family and fulfilling a bigger purpose in life. On finishing high school, he was still unsure of the educational path he wanted to pursue. Growing up, he was inspired by his father, a physician, who runs a successful practice, and his uncle, a businessman, who runs a successful company in Nashville.
Rainer wanted to start a business and began asking himself, “How do I do that?” In the quest to find that answer, Rainer found the UAB Barefield Entrepreneurship Program, led by Patrick J. Murphy, Ph.D., Goodrich Endowed Chair for Innovation and Entrepreneurship.
The program, offering relevant and rigorous courses taught by world-class professors and successful entrepreneurs, combined with intense practical experiences locked UAB as his college choice.
“While researching, I saw a video with Dr. Murphy in it talking passionately about entrepreneurship and helping students start a business,” Rainer said. “I was like, if they can help me start a business, this is where I need to be.”
Fostering entrepreneurial knowledge
UAB’s entrepreneurship program emphasizes experiential learning, equipping students with practical skills while introducing them to Birmingham’s entrepreneurial ecosystem. Rainer says one of his favorite classes was marketing and positioning, taught by entrepreneur-in-residence Ethan Summers.
“Mr. Summers is a real entrepreneur — that’s one of the best parts of the program,” Rainer said. “Business owners who understand the landscape are teaching the classes. Learning from leaders who share real-world insight made a huge difference.”
Rainer was named 2026 Barefield Entrepreneurship Program Outstanding Student.
Rainer credits many mentors he met through the program with shaping his entrepreneurial mindset, especially Murphy, whose passion for transforming his students into world-class entrepreneurs left an impression on him even before they met in person.
“William perfectly exemplifies the powerful balance of scholarly rigor and practical outreach that defines the Barefield Entrepreneurship Program and aligns with UAB’s broader mission,” Murphy said. “He moved seamlessly from classroom concepts to launching real ventures, excelled in major pitch competitions, and led student teams that delivered tangible results for social enterprises and for-profit business ventures.”
According to Rainer, one of the most valuable aspects of the program is the opportunity to compete in pitch competitions at the institutional, local and national levels.
During his time at UAB, Rainer competed in Halloween-themed pitch competitions on campus, the Innovate Alabama Pitch Competition, and three national competitions in Minnesota and Tampa, Florida, where he placed highly against hundreds of schools. He pitched ideas ranging from promoting local rural produce to selling barbecue grills, using each experience to polish his entrepreneurial skills.
“They all served as attempts at starting my own firm,” Rainer said. “They helped me sharpen my critical thinking, presentation and storytelling skills.”
In the final weeks of his collegiate career, Rainer was named the 2026 Barefield Entrepreneurship Program Outstanding Student, an award that recognizes a graduating senior who has most dramatically used their education to achieve real-world outcomes across multiple areas of entrepreneurship.
Launching his firm
Launching a new firm demanded understanding the legal, logistical and branding steps.
“I formed an LLC by meeting with a lawyer, built a website, published original articles, created social media accounts and began producing consistent content,” Rainer said.
According to him, the most critical step was landing his first client, because “With a client comes content, visibility and real stories to tell,” Rainer said.
Rainer secured a local coffee shop as Aim Ventures’ first client. To elevate the brand, he designed a challenge-based marketing concept that takes customers through a journey of exploring Birmingham’s historic landmarks, combining storytelling, physical engagement and digital promotion.
Once Rainer launched his firm, he needed support for event planning. His fiancée, Vivian, who he met at UAB, stepped in to help, creating a perfect team.
“We first met at the Hill Student Center to discuss leading a Bible study together,” Rainer said. “After that, we started finding every possible way to hang out, and eventually, I asked her out, and she said yes. I’m a big-picture, vision-oriented person, and she is extremely detail-oriented, which balances things out really well.”
Rainer is most proud of persevering through a journey that is often uncertain and saying yes to any opportunities that came along.
“There were a lot of moments when I didn’t feel confident in how stable my path was,” he said. “That’s part of entrepreneurship, but it’s definitely uncomfortable. I stayed and explored different professional experiences, like working at a staffing company, writing news articles, supporting campus organizations and working for a Birmingham-based fintech startup.”
Rainer says that, while he explored many experiences, his goal remained the same — to learn, gain experience and figure it out. He encourages other students to do the same and let go of the expectation of always making perfect decisions.
Rainer is both graduating and marrying his fiance this May. “Don’t worry so much about choosing the perfect path right now — because chances are it won’t be perfect,” Rainer said. “Stick with something long enough to learn from it; stay open to other opportunities, but focus on what’s in front of you.”
Rainer’s faith, church community and hobbies like Brazilian jiu-jitsu served as his anchors throughout the challenges of becoming a real-world entrepreneur.
Looking ahead
Rainer is waving goodbye to UAB with both his professional and personal futures sorted. He will both graduate and marry Vivian in May while continuing to grow his firm in Birmingham.
Moving forward, Rainer’s vision for his firm is to operate with a two-pronged strategy: serving established Birmingham businesses with outdated or underutilized marketing, while partnering with startups for more high-risk, high-reward projects.
“That balance will allow the firm to be stable while still being adventurous,” Rainer said.
