We’re a growing B2B SaaS startup. What new revenue streams would you test next?

I work at a growing startup that runs a B2B software marketplace, and I’m currently working on the vendor side of the business.

Our current paid offerings include premium vendor profiles, review campaigns, PPC/CPC campaigns, and content partnerships. Most of our revenue today comes from helping software vendors get more visibility, traffic, and leads.

We’re now trying to figure out what else we can offer without just creating more ad packages. Some ideas I’ve been thinking about are buyer intent data, competitor insights, lead nurturing, custom research, category reports, ABM support, and managed marketing services.

For founders or people who have worked on B2B SaaS monetization, what would you test next? I’m especially interested in recurring revenue ideas that are useful enough for vendors to keep paying for month after month.
