Imagine an agency. Let’s call it 50/50. Half of the clients are for-profit companies; the other half are charities. The for-profit clients pay fees, happy in the knowledge that the service they’re buying from the agency is funding good works. The non-profit clients are happy because they realize value they would otherwise be unable to afford. And the agency’s employees get to spend 50% of their time working on causes they believe in alongside paying clients whose ethics they respect. Goodwill can work for everyone.
