To execute the angel conference, a substantial team is required.

“I love what Angel Conferences do for communities. On a local level, they are a very public demonstration that a community has the next generation of business leaders and the resources necessary to help them succeed. On a global level, Angel Conferences give us the ability to bring new solutions and technologies to market to solve the world’s greatest challenges.”

Stacy Pena

Stacy Peña

USD Free Enterprise Institute
SDAC V Fund Co Manager

Whether serving as Asst. Director of the Free Enterprise Institute at USD, fund manager or an investor, Stacy is committed to supporting the next generation of changemakers and social innovators.

Her expertise and business strengths were cultivated during the 90’s while working in wireless, digital telecommunication start-up companies. She caught the founders bug from her ‘devil in the details’ foresight, scrappy entrepreneurial mindset and start-up speed experience in business development, operations and marketing. She balances her time between her marketing services company and her role as Chief Business Officer at Six Dragonflies, LLC. – a socially minded enterprise offering capital, collaboration, and influential connections for women and under-represented entrepreneurs who remain focused on accelerating economic development and generational wealth
in their communities. 

Stacy and Six Dragonflies, LLC have participated as an investor at the San Diego Angel Conference I, II & IV and served on the fund management team of SDAC II.  As a fund co-manager of SDAC V, she was able to engage on both sides of the table working with companies positioned to scale and make extraordinary social impacts and connecting them with accredited angel investors who are passionate about sharing their treasure, time and talent to solve big problems.
