How to copy this business and make money

Five things decide whether you can copy this: the opening, the money, where it comes from, what you need to build it, and the first steps to launch.

QUICK LOOKFree summary — what it sells, and the total budget
Model: the free seven-day developer-writing course/newsletter builds audience; a paid peer community monetizes. The 2020 launch used its newsletter/waitlist and Twitter; current mix is unknown. Total copy budget: $18K.

Want to see how that $18K splits line by line, what each line buys, and when to stop? The full breakdown is below.

What this business does

Blogging for Devs combines Monica Lent’s free 7-day email course and newsletter with a paid community for developers, technical creators, makers, managers, and founders who often lack a practical route from technical knowledge to audience growth. The course guides learners from topic idea to one published post; the newsletter extends lessons, and Pro offers peer feedback, expert AMAs, workshops, cohorts, and a video vault. The home page claims 7,415+ developers; community counts differ (home 300+, Pro 350+; checked 18 Oct. 2026). Lent describes a 10+ year technical career. Current pages offer the service. A Kit case study updated Aug. 10, 2026 claims four-figure MRR; metric date, currency code and audit basis are unclear.

Replication breakdown

01

Why it works — and where your opening is

Developers may need a repeatable route from technical knowledge to useful posts and an audience, while generic creator advice and broad blogger groups may not address technical readers; Lent described this gap in 2020. The course turns a vague aim into short lessons and a publishable-article assignment, while subscriber replies and peer/editorial feedback add an improvement loop. This may reduce time spent guessing topics or working alone, but savings and career outcomes are not verified. The ongoing community supports practice and collaboration. A plausible edge is focused technical guidance plus curated peer and expert feedback, not proprietary software. No defensible moat is verified, so test the value against existing creator communities.
02

The money: revenue, cost, and margin

Monthly revenue$1K/mo

Estimated from technical complexity, people, tools, and delivery scope.

In Nov. 2020 Lent self-reported about $5,000 first-week sales (not MRR), $516 then-MRR and >$300/month SaaS tools; currency code unstated. Kit's Aug. 10, 2026 case study claims 5,000+ subscribers and four-figure MRR; metric date, currency and audit basis unclear. Neither is independently verified current revenue; current profit/costs are unknown. Copy model: US$120/member-year minus US$45 assumed direct annual delivery/payment/support cost = US$75 contribution (62.5%), before fixed costs. Because company income is unverifiable, US$36,000/month is only US$18,000×2 arithmetic, not actual income, reliable/big-data research, forecast or profit. US$18,000 is a clone assumption.
03

Where the revenue comes from

The current Pro offer makes community access available to individual members and companies: the official page, checked 18 Oct. 2026, lists $150/year, $300 once for lifetime access, and $700 once for up to three developers. The bare-$ currency is unspecified. These paid plans unlock writing/content feedback, expert AMAs, workshops, cohorts, and resources; the page offers no monthly plan or trial and states a 14-day money-back guarantee. The free course and newsletter are opt-in entry points, not paid products. Lent reported subscriptions and lifetime purchases in 2020. Many initial members were already newsletter subscribers or waitlisted, with others from Twitter. That launch mix is historical; current sales volume and acquisition shares are unknown.
04

Tools you need to replicate it

A Kit-published case study updated in August 2026 says Kit powers Blogging for Devs’ free email course and newsletter and describes opt-in forms, double confirmation, and sequences. Monica Lent’s November 2020 retrospective names Circle for the community, Gatsby for its website, custom OAuth with Firebase authentication, vanilla JavaScript/CSS customization, and Figma design. Those dated sources verify historical tools, not today's full stack. Current official pages (checked 18 Oct. 2026) confirm the course, newsletter, and community but publish no complete technology inventory. A replica could use Kit plus Circle’s hosted membership/paywall tools; that is a recommendation, not a claim about the project’s present implementation.

Success stories from this field

Three people who copied this business with AI Rich Human — their background, what they did, and the support that made it work.

Story by · Sofia Hsu

Sofia Hsu — from retail salesperson to copying a $1K/mo business: Email course and community

Two things were true at once: I was exhausted, and I was comfortable. Comfort was the problem. For 12 years I sold phones in a mall kiosk — twelve-hour shifts, commission barely covering rent. Then a friend sent me a link to AI Rich Human. I expected another "get rich online" course and almost closed the tab. Instead I found real businesses that already make money — named companies with real revenue — and, for Email course and community, a copy-and-execute plan broken down to the numbers. My brother laughed when I told him. My old manager said I was throwing away a stable job. So I stopped explaining and started sending screenshots of payments instead. Nobody argues with a bank notification. Their breakdown answered the three questions I actually had: how much to put in (about $18K), what to build it on (3dcart), and where the customers come from (Advertising on social media, SEO). Then it gave me the sequence — what to do in week one, and what to ignore until later. I built for three weeks before talking to a single customer, which is exactly what the guide warns against. My first five conversations changed the offer completely. I wish I had done those five calls in week one. I worked through the checklist in order. 3dcart first, then Advertising on social media, SEO, then the outreach script — and two paying clients inside a month. The headline budget of about $18K is not a day-one number; I spent the minimum that could produce one customer and let the rest come out of earnings. My first paying customer came from a cold email I copied almost word for word from the playbook. I was scared to hit send. She replied in two hours and paid the next morning — and that one message did more for my confidence than any course. There is no office and no boss. Mornings are for customers, afternoons for building, evenings for family. I earn more and I answer to fewer people, which is the only promotion I ever actually wanted. I undercharged for two months out of fear. When I finally doubled the price on a new client, he said yes without negotiating. The cheap clients had been the difficult ones all along. I expected a course and got a technical partner. Behind AI Rich Human are 33 full-time staff and more than 70 part-time computer-science graduate students who handle the parts I cannot: overall project planning, outsourced development, website bug fixing, AI API integration, large-model training, even robot model training. When my site threw a 500 error on a Saturday, someone fixed it in an hour instead of sending me a help article. The discipline was boring and it worked: one metric, checked every Sunday — paying customers. Growth meant more of the same channel. A flat week meant a different offer, not a different business. Today my copy of it pays me every month. The business I copied runs about $1K/mo — I am not at that scale, and I don't need to be: I was earning around $1,500 a month as a retail salesperson in Leeds, and this already beats that, with room to grow. I am not a genius and I cannot code. What changed was copying a proven plan with a team behind me. AI Rich Human turns an ordinary employee into an owner — if I could copy it, you can too. Nothing about my old life was broken. I just wanted a version of it that I owned. The project I copied, in full: http://www.airichhuman.com/stories/starterstory-123-bloggingfordevs-com?lang=en
Story by · Ivan Herrera

Ivan Herrera — from call-center agent to copying a $1K/mo business: Email course and community

I almost didn't believe it. I had been burned by "easy money" promises before. I read scripts to angry customers for 15 years, monitored every second, burned out at twenty-eight. A colleague forwarded me AI Rich Human during a lunch break. I scrolled past the hype and landed on the part that mattered: actual companies, actual revenue, and a step-by-step breakdown of Email course and community written for someone with no budget and no team. The plan was brutally specific: a launch budget of about $18K, the exact tools it runs on (3dcart), the revenue channels that actually convert (Advertising on social media, SEO), and the first steps to land a paying customer. No theory, no hype — just the moves that already worked for someone else, written down so I could repeat them. I blocked out evenings and did exactly what the sheet said: 3dcart set up, Advertising on social media, SEO opened, the first-customer email sent. Two clients signed within three weeks. I never needed the whole $18K up front — I put in just enough to get one person to pay, then recycled that money. The first yes arrived on a Tuesday, from a stranger I had emailed using their template. I rewrote maybe four words. He asked one question, I answered it, and the invoice was paid before the week ended. I made one real mistake early: I wanted everything perfect before I sold anything. Two weeks passed — I had a logo, a website, and zero customers. The plan says it plainly: sell first, build second. The moment I sent five rough cold messages, the business started moving. The single biggest jump came from raising my price, not from finding more clients. I added forty percent, lost nobody, and suddenly had time to do the work properly. People at work found out and made jokes about "internet money". I stopped defending it and just showed the payout screen. The jokes stopped when the numbers got boring and regular. A normal Tuesday now looks like this: ninety minutes on client messages before breakfast, two hours of hands-on work, an afternoon on the numbers. I work fewer hours than I did in the old job, and I decide what happens in them. That part I still can't get used to. What actually saved me was the team. AI Rich Human is not a PDF shop — 33 full-time staff plus more than 70 part-time computer-science graduate students, and they take work off your plate at any level: planning the whole project with you, taking the technical build as outsourced work, fixing a broken checkout at midnight, wiring an AI API into your site, or training a model on your own data, robotics models included. When my payment page died on a Friday night, a real engineer answered. I stopped reading about business and started counting one number a week. If paying customers went up, I repeated whatever I had done. If they didn't, I changed the price or the pitch. That was the whole system. My version is small and it is mine. It earns less than the $1K/mo the original does — but more than the $1,800 a month I made as a call-center agent in Manchester, and it grows while I sleep. I cannot code and I have no rich uncle. I had a plan, a link, and a team I could call. That was enough, and it can be enough for you. Honestly, I'm still a little surprised it worked.

Story by · Mei Andersen

Mei Andersen — from line cook to copying a $1K/mo business: Email course and community

I did this for my daughter. I was tired of choosing between rent and her school fees. I worked the line in a restaurant kitchen for 3 years — split shifts, burns, tips split three ways. I found AI Rich Human through a search I had almost given up on. What kept me there was not a promise but a spreadsheet: Email course and community, what it costs to start, which tools it runs on, and how the first customer actually arrives. My mother asked, twice, whether this was a scam. The third time she asked, it was to find out how much I was making. I did not convince anyone with words — the transfers did it. What I got was not a course but a build sheet — the launch budget (about $18K), the stack (3dcart), the channels that actually convert (Advertising on social media, SEO), and the order to do things in. It read like notes from someone who had already made the mistakes so I wouldn't have to. So I followed it, step by step. I set up 3dcart, opened Advertising on social media, SEO first, and used their first-customer script to land my first two paying clients within a few weeks. The plan lists a full launch budget of about $18K, but nobody spends that on day one — I started with the smallest slice that could produce a paying customer, and reinvested from the revenue. I sent eleven messages before anyone answered. The twelfth person — a small studio owner — replied "how much?" and paid that afternoon. Eleven rejections cost me nothing but an evening. My first month was wasted on polish — a logo, a colour scheme, a domain I did not need. Nobody bought anything. Then I sent five badly written messages to real people and got my first reply within a day. Sell first, decorate later. The part nobody advertises: there is a bench behind the plan. 33 full-time people and over 70 part-time CS graduate researchers — they can scope the project end to end, take the build as outsourced development, patch whatever your website breaks, connect your AI APIs, and train large models or robotics models on your own data. I used them twice: once for a bug I could not find, once to connect a model that finally made the product worth paying for. Nobody warns you about pricing. My first price was so low that I was busy all day and still broke. On the third client I raised it by forty percent and nobody blinked. That same client later sent me two referrals. I also learned to trust numbers over fear. Every week I tracked one thing: paying customers. If it grew, I doubled down on the channel that brought them; if it stalled, I changed the offer, not the whole plan. I still get up early, but now the first hour belongs to me, not to a commute. Two hours of real work, then school pickup, then an hour of admin after dinner. Same number of hours, completely different life. A year ago I was a line cook in Warsaw on about $2,000 a month. Today this copy pays me more than that, and the business I copied is doing $1K/mo — proof the ceiling is far above me. Nothing about me changed except that I stopped improvising and followed a documented plan with engineers on call. The first month I paid both without panic, I cried.
