Describe your startup

What you make, who it is for and how people should get started. Cactal writes the pages, sets up your waitlist or demo request form and publishes the site.

How it works

  1. 1 Pick a design

    Browse by product type and open any design to see it full size.

  2. 2 Add your startup's details

    Your features, pricing, screenshots and where the sign-up button should lead. Cactal writes every page and builds the site from your design.

  3. 3 Publish

    Ask for changes in plain words until it's right, then publish free on a Cactal domain, or on your own domain with Pro.

What an AI startup website needs

The job, not the technology

Visitors already expect AI. Say what the product does and who it is for in the headline, and save how it works for further down the page.

The product at work

A real screen, a sample result or a short demo shows more than an abstract glow. Let people see a request go in and the answer come out.

One clear next step

Start free, book a demo or join the waitlist: choose the main action and repeat it on every page. Two competing buttons in the hero split attention.

Pricing in plain units

Usage and credit pricing confuses buyers. Say what each plan includes and give an example of what a typical month costs.

Clear answers about data

Buyers want to know what happens to what they upload, where it is stored and who can see it. Answer it on a security or privacy page and link it from pricing.

Proof you can stand behind

Customer quotes, case studies and numbers persuade, but use names and logos only with permission. Early on, a changelog or a founder's note can earn trust instead.

Questions

Are these AI startup website templates free?

Every design here is free to start from. You can sign up, build and publish on a Cactal domain without a card and with no time limit. Putting your site on a domain you own is $25 a month on Pro, or $240 a year.

Do I need to know how to code or design?

No. Describe your startup in plain words and Cactal builds, edits and publishes the site. When you want a change, ask for it the same way.

How much does an AI startup website cost?

A custom build from a startup design agency often runs into the thousands of dollars and takes weeks. A builder template costs less, but you still write and fill in every page. With Cactal it's free to build and publish on a Cactal address, and your own domain is $25 a month on Pro, or $240 a year, with no setup fee.

Can I use my own domain?

Yes. Every site starts on a free Cactal address. Connect a domain you own on Pro for $25 a month, or $240 a year, and each additional website on its own domain is $20 a month.

Who owns the website?

You do. Every Cactal site is real React source code, so you can take it and run it anywhere. There is no export to buy.

Are these real AI companies?

No. Each design is an illustration made by Cactal, and the company names, people, numbers and screenshots in it are fictional. Your site is built around your own product or agency.

Can I launch with a waitlist before the product is ready?

Yes. Cactal can build a one-page site with a waitlist form, then grow it into a full site when you launch. The free plan includes 50 form submissions per website a month, and Pro has no limit.

Can people sign up, pay or book a demo on the site?

Sign-up and pricing buttons send people to your own app and the payment tool you already use. Cactal collects demo requests with built-in forms that include spam filtering and email notifications, and a scheduling tool can be linked or embedded.
