Starting a business is arguably one of the hardest things you can do. Most people have no idea how hard it is until they try.
But it’s also one of the most rewarding things you can do. Having a successful business means freedom and control. It’s the ability to turn effort into money…on your own terms. Few things in life are as satisfying as knowing you can support yourself no matter what happens.
Really Good Business Ideas exists to make starting and growing a profitable business easier.
I’m Casandra Campbell. I’ve spent the past 15 years growing businesses across a range of business models, sizes, and industries. I’ve started my own affiliate sites and bootstrapped a brewing company; consulted for startups, government organizations, direct-to-consumer brands, and service-based businesses; and even helped Shopify become the fastest-growing SaaS company…ever.
I’m really good at finding and assessing business opportunities, but I’m most passionate about helping others take control of their livelihoods.

The Substack Shortcut
The Substack Shortcut is a section inside Really Good Business Ideas where you can read all the content I publish specifically about building a business on Substack.
Subscribers can manage their subscription to The Substack Shortcut separately from the rest of Really Good Business Ideas. This means that if you’re not a Substack publisher and you do not want to receive content about growing a Substack publication, you can turn notifications for that content off in your subscription settings.
Alternately, if you only want to receive Substack-specific content, you can instead turn off notifications for the rest of Really Good Business Ideas. But I don’t recommend this because you’ll miss all the general growth content that can be applied to Substack!

The sheer breadth of resources here is impressive, it almost feels like a map where every possible road has been sketched out in advance. And yet, sometimes I wonder if the harder part of starting a business isn’t knowing what to do but having the courage to strip it back to what truly matters.
In my experience, clarity rarely comes from adding more tools or tactics. It comes in the quiet moment when you realize what you can leave behind, what noise no longer needs your attention.
Maybe the real skill for founders today isn’t only execution, but discernment: the ability to cut through abundance and return to the essentials that actually give a venture its pulse.
