What You'll Do

The Head of Philanthropy & Principal Giving (Eastern US) will lead Acumen's individual philanthropy strategy across the Eastern United States, with a particular focus on building new relationships and securing major gifts in support of Acumen's ongoing $250M campaign in service of our 10 year vision. This is a senior, externally facing role for an accomplished relationship builder who can expand Acumen's network, inspire transformational giving, and help shape how we engage major philanthropists during the campaign and beyond.

Working closely with our Chief Development & Partnerships Officer, the Directors of European and West Coast fundraising, and our CEO, this leader will have meaningful ownership of fundraising strategy, relationships, and results. They will cultivate relationships within their own network and build new ones; significantly expand Acumen's visibility across the Eastern half of the United States; and secure the flexible capital that allows Acumen to invest early, take risks, and pursue the opportunities with the greatest potential for impact.

We are looking for someone who brings at least 15 years of experience engaging high-net-worth individuals and a strong track record of closing major gifts. The ideal candidate possesses an existing network of potential supporters – or a demonstrated ability to quickly build one – and can connect Acumen's mission and patient capital model with the ambitions of sophisticated philanthropists who think about giving with the same rigor they bring to investing.

A persuasive storyteller and trusted advisor, this leader must be equally comfortable in a one-on-one conversation, convening a room around a shared purpose, and working with senior leaders to move a relationship toward a significant commitment. They will bring sound judgment, genuine curiosity, and a feel for nuance, along with the drive to open doors and turn relationships into lasting philanthropic partnerships.

This is a rare opportunity to help build the next chapter of individual philanthropy at Acumen, and to help shape a campaign designed to expand what Acumen can achieve over the next decade. It is also an ideal opportunity for an entrepreneurial frontline fundraiser who is motivated by ambitious goals and deeply passionate about leveraging philanthropy to solve problems of global poverty.
