The problem

Every day your website isn't converting, you're losing money.

You know the right funnel would win clients. But every way to actually build one is slow, technical, or too expensive, so it never gets done.

The blank page stops you

Which funnel, what to say, how to structure it - a dozen decisions before you write a word, so the funnel that would win clients never gets built.

Builders eat your time

Drag-and-drop, broken templates, and endless tech settings. Days vanish and it still looks off.

Templates fall flat

Cheap templates look generic and convert like it. You end up rewriting the copy and design yourself anyway.

Meanwhile your ads keep running, your traffic keeps leaking, and the offer that could change your business sits unlaunched.

The solution

Meet Builder OS.

A plug-and-play Claude skill file that picks the funnel that fits your offer and builds it end to end. You just publish.

How it works

Your client getting funnel live in three steps.

From your offer to a client-ready funnel, without ever touching a page builder.

Step 01

Tell it your offer

Answer a few questions about your business, who you help, and what you sell. Builder OS picks the funnel that fits.

Step 02

Claude builds it

It writes the pages, the copy, and the booking flow, then renders your funnel ready to publish.

Step 03

Go live and win clients

Publish to your platform and turn cold traffic into booked calls, subscribers, and sales.

Proof

Websites and funnels people are proud to run traffic to.

The same funnel system behind five years of client results.

What it does

Everything your next website and funnel needs, handled.

Builder OS handles the copy, the design, and the tech, so you never touch a page builder.

Interviews you once

One quick onboarding, no endless prompting. It learns your offer, your audience, and the result you sell.

Picks the right funnel

Lead magnet, VSL, webinar, application, low-ticket, or full website. It matches the funnel to your offer.

Writes your copy

Ship-ready hero, offer, and FAQ copy for every page, in your voice, not generic AI slop.

Builds a design system

One consistent look across every page. Change a color once and it updates everywhere, no templated feel.

Wires booking and checkout

Connects your calendar, forms, and checkout so leads can actually book and buy, not just browse.

Ships production-grade

Mobile-first, fast, and SEO and AI-search ready, so the funnel converts, not just looks good.

FAQs

Questions, answered.

Still on the fence? These are the questions we hear most.

Do I need my own Claude account?
Yes. Builder OS is a skill file that runs inside Claude, so you bring your own account (the free tier is enough to start, Pro or Max if you build a lot). It also adapts to Codex if that is what you already use.
Do I need to be technical?
No. You describe your business and your offer in plain English, and Claude builds the pages, writes the copy, and wires the flow. No code, no page builders, no design skills needed.
Why is it only $27?
Straight answer: $27 turns you into a customer, and some customers go further with us - the $97 backend automations, a strategy call, or a done-for-you build. That is the business model. The skill is complete on its own, and the price stays low because the upgrades exist. No catch beyond that.
What do I actually get for $27?
The plug-and-play Claude skill file that builds your funnel, plus a video walkthrough that shows you exactly how to run it end to end.
How fast can I get a funnel live?
Most people have a live, client-ready funnel within 24 hours, and often the same afternoon. The build itself takes minutes; the time is mostly you refining the copy to sound like you.
What platforms does it work with?
GoHighLevel, WordPress, Webflow, Framer, Wix, Squarespace, Shopify and more. Builder OS outputs clean HTML, so you can publish it almost anywhere you already work.
Can I use it for client work?
Yes. Builder OS is built for agencies and freelancers too. Use it across all your clients to build their funnels and sites, with no per-client license and no extra fees.
What if it is not for me?
You are covered by the 30-day booked-or-refunded guarantee. Build your funnel, run traffic, and if you have not booked a client call in 30 days, email support and we will work with you to get your ROI, or refund you in full - and you keep everything.
