BAR ADMISSION

Heather Pruger is an experienced corporate and transactional attorney with extensive experience helping high-growth, technology-driven businesses navigate growth, complexity, and change. She works closely with founders, executives, boards, and in-house teams through acquisitions, investments, legal function buildout, and leadership transitions.

Heather is particularly energized by working with mission-driven and women-led companies and leadership teams that care deeply about building durable, values-aligned businesses. She brings a calm, collaborative style and practical, business-oriented approach – drawing on both major law firm training and hands-on in-house leadership experience – to bring clarity to complex issues, create scalable legal and operational solutions, and help businesses move forward with confidence. Her early experience as a litigator continues to inform her corporate work today, particularly in assessing risk, navigating conflict, and helping clients make sound decisions under pressure.

Before joining ImpactGC, Heather served as General Counsel of a multinational operating group of a major publicly traded software company, where she built and scaled legal and privacy functions to support a global portfolio of software businesses during an extended period of acquisitive and organic growth. Her experience also includes founding her own legal and advisory practice providing fractional general counsel services and leading M&A transactions, and practicing at major U.S. law firms advising emerging, middle-market, and public companies. Her practice has long had a multinational dimension spanning cross-border M&A, strategic transactions, governance, commercial contracting, privacy, compliance, employment matters, enterprise risk, and dispute management.

When she is not advising clients, Heather can often be found on the trails — running, hiking, or simply being in the woods — or competing in triathlons; she is a two-time Ironman finisher. She is based in Ellicott City, Maryland, where she enjoys gardening, yoga, and exploring nature with her dog, Maggie.

BAR ADMISSION

New York, District of Columbia

Cortney brings extensive experience in impact-oriented debt financing to ImpactGC, having spent over a decade structuring complex transactions that deploy capital to create both financial returns and measurable social and environmental impact.

Most recently, Cortney served as Associate General Counsel at Calvert Impact’s Climate United Fund, where she was lead legal counsel on debt financings for clean energy projects. She also handled general corporate matters, including corporate governance, board liaison work, and compliance issues.

Before that, Cortney spent over seven years at federal agencies—including the U.S. International Development Finance Corporation, the Environmental Protection Agency WIFIA Program, and the Department of Transportation Build America Bureau—structuring and negotiating billions of dollars in financing transactions for international development (in sectors ranging from agriculture to microfinance), water infrastructure, and transportation infrastructure.

At ImpactGC, Cortney advises impact investment funds on portfolio debt investment transactions, governance, and general corporate matters; she also serves as transaction counsel for companies seeking financing from impact-oriented investors and federal agencies. Cortney also represents mission-driven small and medium-sized enterprises. This practice draws directly on her prior experience as the General Counsel of a behavioral health startup. In that role, Cortney handled all of the legal needs for a growing mission-driven company, including drafting and negotiating joint venture agreements, investor documentation, commercial leases, vendor agreements, and employment agreements; advising senior management on personnel matters, corporate governance, and day-to-day operational issues; and collaborating across departments to solve business problems that happened to have legal dimensions.

Cortney is passionate about working with organizations that view business as a force for good. Having spent her career helping deploy capital to support clean energy, water infrastructure, international development, and other mission-critical sectors, she understands that companies and investors committed to creating positive social and environmental outcomes deserve legal counsel who truly understands their mission—not just their business model.

Cortney is based in the Washington D.C. area where she enjoys traveling, playing tennis, and spending time with her family.
