One of the things that I recommend to everyone who's building a new project, regardless of size (and shape and color!) is to consider the power and importance of your own, personal brand.
What I mean by this is that, especially in the beginning, your startup is best reflected and represented by you, the founder and creator! This means that your project will "draft" on your personal brand (i.e. your own personal network) for a while until the project, itself, gains enough steam on its own.
The most obvious example of this is when you see a new project Twitter account, for instance, have < 10 followers but the founder's personal Twitter account has thousands! This is how most projects start, by the way!
With all that being said, if the money is available, I counsel spending a little bit of time curating your network and landing pages (and/or creating new ones) that can help give your new project a bit more "lift" and "surface area" upon which new visitors and new community members can learn about you and your project.
For instance, I own a few proper name URLs like
http://johnsaddington.com that redirect to my personal blog that is 100% managed by me. This means that I get to control the messaging as well as the positioning of my new project!
The next step is actually filling up that personal branding page with content! One idea is to use
Indie Hackers as a blog which is simple, fast, and free! You could even redirect a URL to go directly to your personal profile or project page!
For instance, I use
http://yensquad.com as a short (and memorable!) URL that goes directly to my product page on IH:
Personal branding, especially in the beginning, is essentially the same thing as beginning to seed and establish the foundation for the project's brand, short and long-term.
Eventually, bifurcating the two may make more sense as the project's followership and brand takes off. But, until then, don't dilute your time trying to manage too many social channels or communication tools — keep things simple as you walk through the product-market fit process!
