LinkedIn, for example, would be one in my opinion. The channels for SMB are smaller and harder to see for businesses with IPO in their minds, but forum boards and business groups are amazing for this. I was testing once an idea and proposed a free package to all SMB's in a certain community. I mentioned, that I was doing this to help the community and give back. Majority of requests (and I have got few dozens of them) wanted to go for the paid plan right away, which was few hundred bucks and took few hours of my time to complete. The SMB marketing channels are surely there, but they are small and distributed, so they require much more manual work than regular channels.
