Your Growth Strategy Deserves More Than Conventional Fundraising Wisdom
Every high-stakes conversation your team has, with donors, foundations, partners, board members, or funders, is either moving a decision forward or letting it drift. We make sure your team knows the difference.
What Makes TWG Different
Grounded in How People Actually Decide
Every commitment, whether it's a major gift, a foundation grant, a corporate partnership, or a board member's personal giving, is a cognitive journey. Supporters move from comfort to curiosity to conviction to commitment. Our methodology is built on decision science, social psychology, neuroscience, and behavioral economics to guide that journey deliberately.
Proven at the Highest Stakes
The frameworks behind our approach were pioneered in the world of B2B complex sales, where the research on multi-stakeholder, high-stakes decisions is decades deep. We've translated those benchmarks specifically for nonprofit and purpose-driven revenue, across major gifts, institutional funding, partnerships, and earned revenue.
Built by People Who Know Your World
We're not consultants who parachute in from corporate. Our team has spent 14 years inside nonprofit revenue, navigating board dynamics, donor psychology, foundation relationships, government contracts, development team capacity, and campaign readiness from the inside.
Embedded Where the Real Work Happens
Training sessions get forgotten. Systems don't. We install conversation standards, prioritization discipline, and a coaching rhythm that shows up in your team's actual week, in live donor meetings, foundation calls, board prep, partnership negotiations, and pipeline reviews.
