A joint venture between a non-profit and a for-profit entity can be beneficial to both. the for-profit entity can garner goodwill. The not-for-profit entity can gain more resources for their charitable cause, they can gain an alternate revenue source as well as capital and expertise. But there's a big catch. The non-profit must ensure that its joint venture does not run afoul of IRS rules and that its assets protected and its tax-exempt status is not lost.
