**The product.** A web app that turns a short idea, such as "linkedin post about our new pricing", into a full prompt with a role, a task and constraints, written for the model the user picks: Claude, ChatGPT, Gemini, Grok and others. It also rewrites existing prompts, keeps a library of saved prompts with version history, runs prompts inside the app, and has a Chrome extension for use inside the chat windows.

**Why it worked.** Many people get vague answers from chat models because their requests are vague. Prompt Builder sells the step in between: it asks up to three questions and writes the detailed request for them. Stripe data shows that people paid for this monthly, from US$346 in November 2025 to a peak of US$1,929 in May 2026.

Evidence grades: A = disclosed by a public company, a filing or a payment processor, or verified by one; B = two or more independent reports agree, or a journalist confirmed it; C = a founder claim that no one else verified; D = reported, not verified: one founder claim or a third-party estimate with no second source; E = no revenue figure found, so the headline is a non-money fact and the other facts carry their own grades; calc = computed on this page from graded facts.

## Summary

Prompt Builder (promptbuilder.cc) is an AI prompt generator: a tool that takes a rough request and writes the longer, structured instruction (the prompt, the text you give a large language model) that a chat model such as Claude or ChatGPT then follows. It sells credits, units of use where one credit is one generated prompt, in plans of US$9, US$19 and US$49 a month. Its founder, who publishes under the name Nick Launches, also runs the product launch directory nicklaunches.com, whose footer names the company Nick Launches, Inc.

On his own blog the founder writes that he started as a frontend developer in 2015, became a CTO in 2019 and left that job in 2025 to build alone, with AI agents as his "team". TrustMRR, a site that reads revenue directly from a company's payment provider, lists Prompt Builder with a founding date of 9 June 2025 and a Stripe connection. Its verified monthly revenue rose from US$346 in November 2025 to US$1,929 in May 2026, then fell to US$1,358 in September 2026, with US$1,514 in MRR (monthly recurring revenue, the subscription money that repeats each month) and 137 active subscriptions at the last sync on 30 September 2026.

The revenue numbers are grade A because they come from Stripe through TrustMRR. The Stripe key expired on 1 October 2026, so no newer figure exists. The founder's full name, his former employer and how most customers found the product are not stated in any source we read.

## Pricing

Prompt Builder prices on its pricing page, read 5 November 2026 (grade C)

| Plan | Per month, billed yearly (US$) | Per month, billed monthly (US$) | Limit |
|---|---|---|---|
| Free | 0 | 0 | 5 credits (5 generated prompts) |
| Starter |  | 9 | 1,000 credits a month |
| Pro |  | 19 | 3,000 credits a month |
| Unlimited |  | 49 | "unlimited", 12,000 credits a month before limits |

The page shows monthly prices and says yearly billing saves 20%; the yearly per-month prices were not shown in the downloaded page, so that column is empty. The Unlimited plan is limited to 12,000 credits a month in the fine print. The founder-written part of the TrustMRR profile also mentions a lifetime plan, which the pricing page does not show.

- **9 June 2025** (grade C [1]): Founding date of Prompt Builder on its TrustMRR profile.
- **November 2025** (grade A [1]): First month in the Stripe-verified timeline: US$346.
- **March to May 2026** (grade A [1]): Revenue reaches US$1,862, US$1,719 and US$1,929 a month, the best months on record.

## Why did Prompt Builder (by Nick Launches, Inc.) work?

### A product for a step everyone repeats

Every chat model user writes requests. Prompt Builder sells the rewrite of a short request into a structured one for a chosen model, plus a library to keep the good versions. The price starts at US$9 a month, low enough that an individual can pay it without approval.

### Credits tie price to use

One credit is one generated prompt. Plans differ only in credits (1,000, 3,000, or 12,000 under the name Unlimited), so heavy users pay more and the model cost per customer stays inside the plan price.

### Many pages for search

The site map has 905 blog posts, a generator page for each model and six languages, and Google Search Console is connected to the revenue profile. No source states how many customers came from search, so this page records the channel as unknown.

### A second business for distribution

The founder also runs nicklaunches.com, a launch directory with more than 3,500 products by its own count, where he writes about launching and lists Prompt Builder as his product.

## How it was built

These details come from the founder-written part of the TrustMRR profile, the product's own pages and the founder's blog. They are grade C, except the Stripe connection, which TrustMRR verifies.

- Frontend: Next.js, TypeScript, Tailwind CSS and React.
- Backend: Anthropic, AWS, Docker, MongoDB, Neon, PostgreSQL and Vercel, as the founder lists them.
- Payments: Stripe, connected to TrustMRR through an API key until it expired on 1 October 2026.
- Measurement: Google Analytics and Google Search Console, both connected to the TrustMRR profile.
- A Chrome extension puts the generator inside the ChatGPT, Claude and Gemini chat windows.
- The founder writes that he builds alone with AI coding agents, using Claude Code and Codex to review each other.

## Who tried this before Prompt Builder (by Nick Launches, Inc.), and why did they fail?

Three companies in our database of failed startups sold a better way to use a product that someone else controlled, and lost when that owner built the feature in for free. The values below are from that database and are not independently verified.

The failed startups come from our database of dead startups, retold here in our own words; Its entries are AI-assisted summaries of public sources, so they carry no evidence grade.

### Xmarks (2006 to 2014; funding US$9M; cause: Competition)

- Promise: Sync your bookmarks and tabs across browsers.
- Why it died: The browsers built sync in, for free.
- Record: 

### Readability (2009 to 2015; funding US$5M; cause: Competition)

- Promise: Clutter-free reading of any web article.
- Why it died: Browsers added a free reader mode, and few readers paid.
- Record: 

### Xobni (2006 to 2013; funding US$42M; cause: Competition)

- Promise: A smarter inbox inside Microsoft Outlook.
- Why it died: Tied to Outlook, which Microsoft improved itself.

## What changed

Each of the three added a missing feature to a product owned by someone else, and the owner then shipped that feature for free. Prompt Builder makes the same bet on chat models: it writes the detailed request that the chat model could, in principle, ask for or write itself.

Two things differ. The product costs one person very little to run: the founder reports a 90% profit margin on TrustMRR, and there is no funding to pay back. And it is not tied to one platform: it writes prompts for Claude, ChatGPT, Gemini, Grok and others, so one provider's change hurts less. The verified figures also show the risk already at work: revenue fell by 29.6% from May to September 2026.

## Can one person copy Prompt Builder (by Nick Launches, Inc.) now?

**Verdict: Yes, as a small business, with care about the risk.**

The product is a model call wrapped in a clear interface, a library and a credit plan, built by one engineer. The verified result is about US$1,500 a month after a year and a half, and falling, so the copyable part is the method, not a large outcome.

1. Pick a repeated step that people do badly with chat models and sell the finished step, not access to a model.
2. Charge in credits so that model costs never exceed the plan price.
3. Support several model providers so that no single one can remove the need.
4. Connect revenue to a verifier such as TrustMRR so buyers and readers can check it.

**What is still open.** Narrow prompt tools for one job or one profession (legal briefs, product photos, code reviews), where the chat apps' general help is weakest.

## What could go wrong for Prompt Builder (by Nick Launches, Inc.)?

- **Revenue is falling.** Stripe-verified revenue peaked at US$1,929 in May 2026 and was US$1,358 in September 2026, 29.6% lower. The Stripe key expired on 1 October 2026, so there is no verified figure after September.
- **Free chatbots may make prompt generators unnecessary.** Model makers publish free prompting guides; Anthropic's guide says Claude "responds well to clear, explicit instructions" and explains how to write them, which is what Prompt Builder sells. Chat apps can also ask clarifying questions themselves. The predecessors on this page lost when the platform owner added their feature for free.
- **Dependence on model providers and on Google.** The product sends requests to other companies' models (Anthropic in the backend, and Grok, Gemini, GPT and DeepSeek in its Assistant), so their prices and terms set its costs. Its 25,235 visitors a month are measured through Google Analytics and Search Console, and its site has 905 blog posts and a page for each model in six languages. That large search-oriented content footprint depends on Google's ranking; no source says what share of customers came from search.
- **The owner's other business sells directory backlinks.** The founder's directory nicklaunches.com sells a one-time service, from US$99 to US$199, that submits a product to 30 to 100 other directories so the buyer gets "dofollow backlinks" and a higher "Domain Rating". Prompt Builder's pages that we read do not sell or link to it. Readers may want to check how search engines treat such paid link building.
- **The founder is not fully named.** The founder publishes as Nick Launches and does not give his full name or his former employer in the sources we read. The company name Nick Launches, Inc. appears only in the footer of nicklaunches.com, and the Canadian location comes from TrustMRR and the governing-law clause of the terms. The G2 rating on the home page was not checked.
