Less so for b2b, but during product development a third way is to reduce the length of the runway itself by making sure developer resources get applied to their core problem: development.

For us, that meant things like paying a relatively small monthly amount for services that would otherwise have to be administered by our development team: things like repo/wiki hosting (github) and website administration (rackspace). If you consider that every hour of developer time costs the company $25-$50+, these services make a lot of purely economical sense as well.
