A multi-unit operator that became a platform.
Gramcor Corporation is privately held, founded in 2018 and based in Charlotte, North Carolina. We started by operating units, and built from there into franchise rights, brand ownership and the real estate underneath.
Built from the unit up.
Most franchise platforms are assembled from a desk. Ours came out of running businesses: managing labor, negotiating leases, watching build-outs slip and pulling them back on schedule.
That experience shaped the company we now run. We hold franchisor rights in Dapper Doughnut, act as area representative for THE DRIPBaR across North Carolina, are a franchisor of THE DRIPBaR across Canada through our ownership stake in the company holding the brand’s Canadian rights, and hold the area representation for CoreLife Eatery in the Carolinas and Virginia, where we also operate the restaurants ourselves. We also own two concepts of our own, both in active development: Hometown Daytime Restaurants and Sport Fundamentals.
Alongside the brands, we structure and sponsor commercial real estate — because the site decision and the operating decision are the same decision.
The result is a small company with a wide brief: award and support franchises, operate restaurants, develop sites and manage investor capital, all under one roof.
What our motto means in practice.
Decisions without a queue
Inquiries reach a decision-maker, not a call center. We underwrite quickly, give a direct answer, and do not keep candidates or investors waiting for a process that was never going to end in yes.
Documented, not improvised
Territory plans, underwriting models, opening checklists and investor reporting are written down and repeatable. The same standard applies to a single unit and to a full syndication.
Plain answers, promptly
We return messages, explain the reasoning behind a decision and treat every party — franchisee, investor, landlord or guest — as someone whose time has value.
Who founded and runs Gramcor.
Three founders. Advanced degrees, operating scars, and every discipline the platform needs — held in-house. Franchise support, development and investor communication are handled by the same people who make the decisions.
Danny Grammenopoulos
Founder & CEO
Danny founded Gramcor and leads the company across both pillars. His work covers multi-unit franchise development, franchisor operations, real estate syndication, financial modeling and underwriting, and investor relations.
He also serves as a Director on Locate.ai’s real estate advisory team.
He is the point of contact for franchise awards and for investors reviewing a Gramcor-sponsored transaction.
DisciplinesGeorge Grammenopoulos
Co-Founder & VP, Operations
George runs operations across every Gramcor brand: Dapper Doughnut, the CoreLife Eatery restaurants we operate, franchise support for THE DRIPBaR in North Carolina, and THE DRIPBaR Canada, where he serves as VP Operations.
He is also a commercial real estate broker with Locate and a Director on Locate.ai’s real estate advisory team — so the person judging a site is the person who will have to open and run it.
Day to day, that means standards, staffing, vendors, opening sequences and the operating detail behind every brand on this site.
Credentials ScopeMarilyn Jackson
Co-Founder & VP, People and Culture
Marilyn is the glue of the platform. Systems, support and training — the part that decides whether a good model survives contact with a real store — are hers.
She builds the onboarding, training and support structure every brand runs on, and leads People and Culture across the company. With Gramcor since 2019.
Credentials FocusOur team
Gramcor blends cross-generational operating experience — people who have worked units, opened territories, managed build-outs and handled investor reporting. We keep the team small and close to the work.
Franchise support, development and investor communication are handled by the same group that makes the decisions.
Location intelligence
Gramcor is aligned with Locate.ai, the AI-powered retail real estate advisory whose mission is to help brands find where they belong. Locate.ai reports serving more than 200 brands and being named the #1 real estate advisor by Entrepreneur.
Danny and George Grammenopoulos serve as Directors on its real estate advisory team, so our site selection is informed by institutional-grade AI location intelligence. How that shapes our real estate work
