I started a news letter on the technology behind data governance, privacy and security. I've done a lot of research in this area as part of bootstrapping Tokern. The news letter seems like a good medium to share my findings. The website also has a blog but it doesnt have as much reach as substack.
Also the value of the news letter has independent value. So I created a landing page and started a news letter using substack. Please check it out and give me feedback.
