Vatsal Shah In the last couple of years, there has been a clear rise in solo founders and lean agency setups.
One person now builds the website, writes the blog, runs outreach, and manages growth.
In fact, I myself have worked this way.
I used AI and agency tools to handle SEO, content, and outreach without a large team.
If you are looking for agency level tools that actually help you scale without adding complexity, this list is a good place to start.
