- The market is extremely tough. Maybe you noticed how much advertisment squarespace and Wix do. The reason being that these pages typically have small businesses as customers. The issue with these type of businesses is that they go away quickly. Most don't survive 6 months. So you need new customers all the time to keep up with the high churn.
- You do not have price dominance. The price is very competitive and companies with huge backing (like Squarespace / Wix) will dominate you.
- The intended target audience is actually not that keen on doing everything themselves. They don't know about online marketing, SEO, or other "special skills". Actually, they just need someone they can call when they have an issue.
- Developers and agencies prefer open systems like Wordpress, Gatsby, or others. They also value a vivid ecosystem of plugins and themes. They typically don't commit to proprietary software, because you never know how long it will be around.
In any case, I wish you the best of luck with the product. It looks nice! I hope you can use my experiences to advance your business.
