Pitch Dingman Competition, the Dingman Center’s signature annual competition, provides the university’s most talented student entrepreneurs the opportunity to compete for seed funding and exclusive access to venture development resources. This year, the Dingman Center had more prize money available than ever before and three competition tracks for University of Maryland students to compete. Students from any college or major can now compete for over $100,000 in prizes.
Beyond funding, the competition provides a vehicle for entrepreneurs to learn the skills needed to grow their ventures and deliver a successful venture pitch. In the finals, the top student entrepreneurs deliver pitches to an expert panel of judges composed of founders and investors.

You must complete an application for your team to be considered for the Pitch Dingman Competition. You may indicate which track you prefer in the application. Based on your interest and your application responses, the Dingman Center will make the final decision on which track your venture will compete in.
All tracks' applications consist of a series of questions about you and your business as well as a pitch deck, though there are some track-based differences below.
The Ideas Track: Be prepared to answer what your venture idea does, what problem it solves, and for whom. Additionally, you will prepare a short pitch presentation (no more than 5-7 slides) providing a brief overview of your business idea. Feel free to be creative in how you communicate this information. Some topics to include in the pitch deck are:
- What problem are you trying to solve? How many people have this problem?
- What is your solution to the problem?
- Previous attempt(s) at solving this problem and why is your solution better?
- How will you make money?
- Founder team – What backgrounds and experiences do they bring?
- Use of prize funds
The Quattrone Tech Venture Track and Main Street Track: In addition to some clarifying questions, you will prepare a short pitch presentation providing a brief overview of your business idea. It is meant to help you—as an entrepreneur—to practice and hone your ability to verbalize and sell the idea to early-stage investors such as friends and family, angel investors and venture capital firms. The key is to share your passion and enthusiasm for your idea. Your pitch deck should be short (no more than 5-7 slides) and to the point. Some topics to consider for the application questions and to include in your pitch deck are:
- What problem are you trying to solve?
- How big is your problem? Talk about addressable market size.
- What is your solution to the problem? What is the value proposition for the customer?
- Who are your competitors and why is your solution better?
- How will you make money? What are your revenue stream(s)? Marketing and distribution strategy?
- Management team – What backgrounds and experiences do they bring?
- Current traction – Do you have existing revenue?
- Plan moving forward – How will you use the prize money to grow your business and what are your targets for the next six months?
Teams will also want to submit materials that will be used in print, web, and other media including:
- Team descriptions
- Team/team member photos
- Product or prototype photos (if applicable)
- Company logo (high-resolution files)
73%

About our Partners
David and Robyn Quattrone have been supporting the Pitch Dingman Competition since 2015. In 2020, the Quattrones significantly increased their support by providing funds that allowed the Center to go from offering $30,000 in total award funding to offering $65,000 in awards.
As a Pitch Dingman judge, David enjoys engaging with students on their innovative business ideas. It’s something that the family looks forward to every year.
“Every time David comes home from the competition, he tells us all about what the different submissions were,” Robyn says. “Even our kids are interested in it, which is not always the case when you talk to them about work.”
“The program inspires people to think creatively, launching something new or transforming an organization from the inside. That’s what makes the work compelling,” says David. “Hearing how people can get those lessons and experiences to use on their own adventures or create change within their spaces is rewarding and makes me excited for the future.”
Additional funding is provided by members of the Dingman Center Board of Advisors.
The Dingman Center would also like to thank the following sponsors:
- Chris and Vidya Ballenger '89
- Parsons Ventures, Inc.
- Amazon Web Services
