Please vet my startup idea - A platform to sell modern React UI kits & components library

This is my first post after being here for 5 years 😃.

I'm a UI inclined frontend engineer, many times at the beginning of projects I've had to recreate the same set of components, layouts and visual functionality for a new SaaS product with React.

While speaking to a colleague, he asked me if I had any UI for an admin dashboard that I can use to build a new UI. I didn't, I had to design and build one.

Why?

• The UI kits found online are (for lack of a better word) fugly, they are ancient and give your product a dated look
• Customisation: You might find a good one you like, but with the amount of customisation one has to do, it's better to build from scratch-ish

This made me think about creating a UI kit/component library for people like me who want to quickly build their product's UI with modern aesthetics and a powerful tech-stack (React+Next.js).

I believe the UI kit/component library will be very useful to

• busy CTOs/technical co-founders who have to code a SaaS product
• software agencies who build a lot of new products
• freelancers

Question: do you think I'm targeting the right customer? Is it lucrative enough? Is there a pain? If it's a pain for you, can you tell me more about it?

Benefits of the product:

• speed of execution for the customer
• modern aesthetics
• themeable (quickly customize the look and feel to match your brand)
• composable (create new layouts, pages & functionality with ease)

Question: as a frontend developer, do these features seem relevant to you and affect whether you buy a UI kit/component library?

Some other things:
I want to focus on theming the UI kit around certain industries, because, from research I noticed that the UI kits out there are a bit too general and will require more work from a developer to make it useful.
They are:

• marketplaces: connecting this people and that people
• data/dashboards: these days, every one visualises data somehow
• finance/fintech services
• crypto services: related to finance and dashboards

Question: should I tailor to these services to these industries? Should I tailor it at all?

Pricing and business model:
I'll sell tiered licenses to get access to the kit/library. There'll be:

• individual - $99
• agency - $499
• lifetime unlimited - $899

The main difference between the licenses is how many projects can be built and shipped with the template and how many distinct developers can be working on them at the same time.

Question: Will people accept this pricing, especially when there's a lot of free products on the internet? How can I enforce this licensing and prevent losses from reusing a license?

Thanks!
