Ask HN: Site to maximize corp gift match programs?

Google matches up to $6,000 in donations for every employee. It's hardly used to it's full potential.

Many other companies have gift matching as well, and $4B-7B goes unused [1].

What do you think about a site/app that matches interested donors to employees who don't use their max donation?

Not sure if the tax deductible nature could be preserved, perhaps with donor advised funds, but it might depend on the gift matching program.
