Thoughts on doing this as a service for other B2B agencies/SaaS?

I have a side project called the growth archive, where I curate real world B2B marketing examples in a weekly newsletter and also my gallery site. I've used this as a strategy to show my expertise, build connections and sign new clients for my growth assistant agency. For example, I could have a separate email marketing service that focuses on sharing successful real world web design examples with stats and trends around web design and use that to nurture subscribers and nudge them to use your service. Setup effective survey's, polls and welcome sequences to get data about these subs too. Also can be used as ready made content for clients to repurpose on their social media channels too.
