1- Cross-promotion: Reach out to other SaaS companies with mid to large email lists or social following, work together on a cross-promotion strategy. Few have done it but It's an incredible strategy. (There is a tool to do this with other SaaS businesses at saascompanions.com)

2- Job posting: Yep, jon posting is an effective strategy to create hype around your product, you can also use it to chat with your prospects while skipping the sales process (If you know what I mean)

3- Competitor flirting: Got competitors with larger audiences? Don't try to avoid them, gently provoke them in social media, they will be forced to react and it will create a sense of reciprocity for people that are considering the same solution.

4- Database exchange: I have participated in the exchange of +20k contacts between two major retailtech startups, both have gained MM$ after this simple operation. It's not that easy because there is some technical and legal considerations, But once done properly It's powerful. (People are doing it successfully on saascompanions.com (check sales booster section)
