Are there investors who can support startups with just hosting for example

I'm raising funding for my startup. It's an early stage social network startup albeit with users and some traction. One of the advisors on my team (not technical) thinks we can get investors who are providing us with free hosting for example. Or for example get an sms company to partner with us so they send out our SMS for us for free in return for a percentage in the company. It goes against the conventional wisdom I know because I know basically investors will invest an amount say $1M in our startup and we do whatever we want with it.
