The Senior Director, Growth is a senior individual contributor responsible for driving net-new growth across Institutional Membership and Studio services. We are seeking an experienced, commercially-driven business development leader with executive presence and deep experience selling to leaders across corporate social impact, CSR, public affairs, and/or philanthropy. This leader owns pipeline development, deal strategy, and close for new memberships, while collaborating closely with members and internal teams to identify, advance, and close cross-sell and upsell opportunities within existing accounts. This role plays a critical part in shaping NationSwell’s presence within the corporate social impact and private philanthropy landscape. Success requires strong commercial instincts, a nuanced understanding of executive priorities, and the ability to position NationSwell as a high-value strategic partner rather than a transactional vendor.
