Five months. Sixteen builds. One reason.
Every date below comes straight from the project history. Nothing rearranged to look better than it was.
This is not a pitch. It is the story of one real business that needed its owner's time back, and the five months of building that followed: the Dojo where my AI ninjas train and work. Read it, keep what is useful, and if you see yourself in it, there is a simple quiz at the end, and a Dojo of your own on the other side of it.
Sensei Rick Tew
I'm Rick Tew: 25 years a martial arts sensei, 16 real builds since March. I build and train an AI workforce for your business, and a human presses every send.
Everything on this page is a build you can open: the app that runs my gym, the game on the Apple App Store, the console that runs it all. Five months of work, dated from the project history. If you want the same thing done for your business, the quiz at the end works out where I would start.
What you see on social right now: people claiming to be multi-millionaires, even billionaires, or super marketing experts. They saw an opportunity, and it is not your problem they want to solve. It reminds me of the old seminar speakers who never built anything, taught you how to make money, and ironically the teaching is what made them the money. I'm not from that playbook. So instead of a pitch, here is what actually happened.
Every date below comes straight from the project history. Nothing rearranged to look better than it was.
I run NinjaGym on Koh Samui: martial arts for kids, seven days a week. I opened my first school at 19, and this one grew fast. Great problem, real problem: the admin was eating me alive. Bookings, memberships, belts, birthday parties, questions, payments.
Here is the honest part: I am a Ninja Nerd. I love learning AI and building with it. Most owners do not, and never want to. That is exactly the deal that makes this work: I geek out on the machine, you get your time back for the part only you can do. Win-win.
The numbers are not the point. The point: one app keeps every booking, belt, payment and member organized, on auto, while I teach the classes.


It started embarrassingly small: me, an iPad, and a couch, describing what I needed in a chat window. A little web app came out the other side: a page that lives in a browser tab, good enough to prove the idea. It worked. That was the moment the penny dropped.
So I got serious. The toy became a real app: full stack, proper code, a database behind it, installable on a phone, check-ins, memberships, a new belt rank every five sessions, a free session every ten visits. That is the difference between a web page that demos an idea and an app that runs a business. 685 rounds of changes later, it runs the gym on auto while I teach.



Home, events and the shop. Real captures from ninjagym.com today, not mockups.


Once you see it, you cannot unsee it. The proposals, the flyers, the cartoony blue ninja mascot the kids love: made with AI. We play music in the gym from 10am to 8pm, so I used AI to make our own songs, commercially owned, and then built a way to play them: volume, track, on and off, all controlled remotely from my phone. It did not stop at the gym: my spa app opens with its own music so the ambiance starts before the first tap, and my console carries my two working moods, alternative when I want drive and Mozart when I want focus. Or silence. I work either way.
Then the till. I bought a POS system whose built-in software wanted to nickel and dime me: $5 per staff member per month just so each person could enter a PIN, open the drawer, and have transactions recorded under their name. Same again for inventory. Same again for bookkeeping. So I built my own POS backend instead: staff PINs, named transactions, inventory, the books, and a lot more the vendor never offered. A service fee became a system I own.


In my twenties I wrote a stack of small books for my martial art students: a five book system, a memory method called Tew's Total Recall, a language adventure, and The Adroit Swordsman, a vocabulary story that now exists in four editions from astronaut to spy.
They sat unfinished for two decades because finishing them was a full-time job I did not have. In April, they started becoming finished things: real books, then working apps.

Every builder has one goal they carry for decades. Mine was a game with my name on it, on the Apple App Store. In one May, DungeonHole, AstroHold, TEWGO, Ninja Village and Ninja Defense all went from nothing to playable.
TEWGO made it onto the Apple App Store. Honest notes from the work: the other games are still fighting me, games are genuinely hard, and apps and business tools are far easier. That honesty matters later in this story.



TEWGO, real captures from my phone: feudal Japan, space and ocean boards. Every theme has its own background music, made by me.
TEWGO is on the Apple App Store. Five in a row, two to capture. The other four games are still mine to finish.

Heroes, the horde, marines, cyborgs and one very good dog. Every one animated in eight directions. These are not a promo render: they are the exact frames the games draw, at their exact size, which is why the big ones tower over the small ones here the same way they do in a fight.
Three of the five, captured mid-session. Same characters as the wall above, doing their job.
One dark screen runs my whole working life, from my phone, my iPad or the couch. Nobody sold a console like it, so I built my own. And be honest: who does not want a command center where you get to play overseer of everything you own? Tap the buttons below; they are the real ones.
The strange part: my own intel feed kept showing big companies announcing features this console already had. Not genius. Ninja awareness, applied early, and that is exactly what I bring to your table.
"Is everything running?" answered honestly, including "no". Every business, every build, one glance.
Every project is a card: three building today, twenty-six waiting their turn. Drop an idea in, watch it become real.
The daily work that gets done because the factory exists. First you BE it, then you DO it.
Type a mission, press GO, read what came back. A security sweep on the whole machine is one button on the same page.
Scouted against MY projects instead of an algorithm's guess, and every story lands with a Be and a Do button, because reading was never the point.
Flights, routes and rules researched while I sleep. Even my holidays report to the console.
The five book system I teach, the art of winning, became a working app: one idea a day, practice it, prove it is yours in a short check, build a streak. The full ACE method is free forever inside it.
The core principle of WinJitsu is also the principle of this page: your winning method must be your truth. You can learn methods from others, but to own one it must align with you. If building with AI is not your truth, do not fake it. Borrow mine.

The books are real and finished. The app screen is the new look I am moving WinJitsu to, carried over from the Gooffy Ninja ShhT page at ninjagym.com/gns, because the old one was honest and dull. Live today at winjitsu.com, in its old clothes.
I showed a business owner what I had built. He asked me to teach his team, and six-plus hours of teaching later the request quietly changed to "could you just do it for us?" So I did: their support desk now drafts a reply to every customer mail for one human press, and an overseer answers "is everything running?" truthfully, including "no".
That request is the whole business. You do not have time to learn this, and you should not have to: your hours belong where only you can spend them. I call it AI to HI: I run the AI so you get your time back for Human Interaction. The handshakes, the classes, the customers.
Their names stay out of it on purpose. The build pages and proof exist for every claim on this page.
Games, businesses, a spa, a hostel, a gym, a console and a method. The row below is not renders or mockups: each one is a live capture pulled off that app's own address, on a phone, exactly as it loads for anyone who taps it. Including the ones that open onto a sign-in wall, and the one I already told you looks dull.
Twelve of the fourteen are in the live row. Ninja Village runs landscape only, so it sits up in the game scenes instead, and NEWNEI is not public yet.
Take SabaiSen, my spa app, as the example, because it makes the mistake easy to see.

A customer opens SabaiSen and sees a clean page: treatments, prices, a booking button, music that starts before the first tap. Visual, convenient. And if that were all it was, a fair owner would shrug: "my customers would rather just call. We can do this by hand."
These are not features of a website. They are the machine underneath it, and they add up into something no amount of doing-it-by-hand can match: the recording, the history, the fast checking, the adding-up, all happening on their own while you work the room.
Even if every single booking still arrives by phone or walk-in, the moment it lands in the system instead of a notebook, it becomes searchable history, an invoice, a line in the books, a number in the bird's-eye view. The front of the app is convenience for your customers. The engine is capability for you.
Skipping the whole thing because customers ignore the front is throwing away the part that was yours.
By hand is slow, tedious, and done twice when it goes wrong. Worse, it leaves no record: nobody can answer "how did this March compare to last March", so growth runs on gut feel. And the worst part is quiet: by hand, the owner is the system. The business cannot run for a day without you, which means you can never step away from it.
That was me. A gym full of kids and no time left: bookings, memberships, belts, questions, payments, all through my hands, every day. The engine is what gave me my evenings back, and my customers never touched it.
When the machine exists, opening a second location is copying a machine that already works: same bookings, same books, same staff PINs, same bird's-eye view, live on day one. By hand, a second shop doubles the chaos. With an engine, it hits the ground running.
I learned this the blunt way at my own till: the POS vendor wanted to charge me per staff member for basics, so I built my own POS backend: staff PINs, named transactions, inventory, the books. That engine is mine now. If I open shop two, it comes along for free.
Shortest version I have: the website is the ten percent above the water. Buy only the visible part and you bought a brochure. The engine underneath is where the time comes back, and it works for owners who never touch a computer, because running it is my job, not yours.
Almost every business that says it uses AI means this: a few people type questions into a chat box, each in their own way, and whatever they work out stays in their own head. It helps a bit. It is not something the business owns.
Everyone has their own trick, and nobody can see any of them.
One way of working, written down once, and every worker has it.
This is just how a dojo has always worked. Nobody invents their own private kata in the corner. The whole school trains the same form, the sensei sharpens it, and the week it gets sharper, everybody got sharper. One person improving is one person improving. One form improving is the school improving.
So that is what I set up in your business. Your best way of doing a thing gets written down properly, handed to every AI worker you have, kept current, and it belongs to you. Not to me, and not to whoever happened to be good at chatbots.
I run my own shop this way first, the same as everything else here. Everything my ninjas know sits in one place, kept like code with every version saved, and it installs everywhere I work. Sharpen one and they all get sharper the same day.
Auto-drafted replies, self-filing payments, bookings that run themselves: AI agents and systems that hand you your hours back, with a human press on everything that matters. Each one works stand-alone, plugs into the system you already have, or we build you the system around it. You never need to like computers for any of it: that is my half of the deal. I only build for you what I already run.
An AI agent reads every support mail, day and night, and drafts the reply from your own written answers. Hours back every week, zero robot answers. Runs live in my business today.
🥷 Want this one? Mail my Ninja"Money received" mails auto-file and auto-match against what is owed; one press confirms and writes the books. No more "did that payment come in?". Live on real payment mail today.
🥷 Want this one? Mail my NinjaPeople book you without an account or email ping-pong; reminders, reschedules and cancels handle themselves. This system ran my own gym while I taught the classes.
🥷 Want this one? Mail my NinjaNamed AI agents with their own mailboxes: ask the numbers desk a question from your phone, the answer comes back by mail. No agent touches money or the outside world. Mine work this way today.
🥷 Want this one? Mail my NinjaA brief goes in, three drafts come out in your voice; only the one you approve ships, and the day's numbers land in one glance. A marketing department's output, minus the payroll. Live in daily use.
🥷 Want this one? Mail my NinjaThe system plans exactly what your ads must deliver, drafts the copy for your approval, and never spends a cent itself. You hold the wallet; it holds the discipline.
🥷 Want this one? Mail my NinjaA guided workbook, an editorial pipeline, and an AI coach that asks better questions but never writes for them. Running in a real publishing house today.
🥷 Want this one? Mail my NinjaThe brain behind the chat box and the drafted replies: it answers only from facts you verified and says "I don't know" instead of guessing. Every miss it logs makes your library smarter.
🥷 Want this one? Mail my NinjaAI agents get smarter only by proposing notes you approve, and nothing is ever deleted, so you always know what they know. Switched on in my own agents today.
🥷 Want this one? Mail my NinjaA self-audit on your page: visitors bring their own numbers, the math tells the truth, and the answer is never held hostage for an email. The quiz further down this page is it, live.
🥷 Want this one? Mail my NinjaVoice and video built into your own app: staff dial a member, a paid room opens the moment payment lands, no-shows end in an automatic refund. Built, in human testing now.
🥷 Want this one? Mail my NinjaTap a row to see it, tap the ninja to want it: your mail lands with my Ninja Agent first, which is the Front Desk up there answering for itself, and I take it from where he leaves off.
Here is the part almost nobody says out loud: only a tiny slice of people using AI will ever touch the builder tools, and that is fine. You should not have to. Your strength is somewhere else, and that is the whole point. I use AI so you can do your HI: Human Interaction, the part of your business only you can do. The method is simple: first we figure out what you want to BE (the builds you have, the builds you need, the factory behind them), then we wire the DO (what gets done daily because the factory exists). I build your Dojo and train your AI ninjas to work on your projects. In the gym I am the Sensei. In your business, same job.
Your first hire takes the one task that eats the most hours: usually the inbox. It drafts, it files, it proposes. A human presses every send. That rule never bends, at any belt.
Ninjas earn belts the way my gym kids do: by showing up and proving it. A ninja that has earned trust gets a wider lane, and desks start passing work to each other, support to bookings to money.
A workforce with one view over all of it, and an overseer that answers "is everything running?" truthfully, including "no". Every judgment call still yours. Payroll cost of these hires: about zero.
Honest frame: give every AI hire a 2015 job title and you get a 2015 org chart. I hire the roles a payroll would reject, and every one starts at white belt: propose only, prove it, then earn the next belt. Nothing sends, pays, or posts itself until it has.

Monthly subscription. Cancel anytime, effective at the end of the paid month.
Straight answer to the obvious question: both tiers are me doing the building, because that is the product. The difference is who runs the daily work once the Dojo stands: you, or me. And the line that keeps it honest: you are hiring my service to build and run your AI workforce, not hiring me as your product developer. Seats are capped because a sensei who takes every student teaches none of them.
Want an actual product built: an app, a site, a backend, a custom Dojo beyond the subscription? The going market rate for a developer is around $150 per hour. My rate is $222 per 2-hour block, which works out under market, or $2,222 for a 20-hour package: enough to build you a custom Digital Dojo of your own. Scoped and agreed in writing before the clock starts.
Ask about a buildYou did not start your business to do admin. Yet there it is, eating your evenings.
The repeatable work, the same questions, the scheduling, the invoices, the chasing, does not need your judgment. It just needs your hours. And it takes them, every week.
I build you a Digital Dojo: a small AI workforce, trained on your business, that drafts and files that work. Every send, pay and post waits for a human press. Judgment stays yours.
It runs my own gym: 800+ member families, 30,000+ sessions booked, on auto while I teach. It runs a client's support desk today. TEWGO sits on the Apple App Store. Every claim has a build behind it, higher up this page.
Twelve questions, three minutes. The result is computed from your answers alone, and you see it without giving an email.
Take the quizLonger than these usually are, on purpose: I am not trying to qualify you out in three taps, I am trying to work out how I can actually help. It does not assume you have a company and it does not assume you want an email robot. It asks what you are trying to move, where the hours really go, what runs the work today, and how you honestly feel about computers. Three minutes. The result is computed from your answers alone, and you see it without giving an email. The belt bar fills as you go, white through black.
No assumption that you run a company. Plenty of the best work I have seen started as somebody's side thing.
Tap everything that is true. This is the question that decides what I would actually build you, so do not be shy.
Yours or whoever does it. Wage plus the cost of them not doing something better.
Mine was a game with my name on it. It took me twenty years and one May.
There is no wrong answer here. It only changes who ends up driving.
Honest math: your number is the hours you reported for one task, times a 60% draft-and-file share, times the hourly value you gave it. Estimates, clearly labeled as estimates, from your answers and nothing else.
Live captures off each app's own address, not renders. The full wall of fourteen is further up the page; these four are the ones a client meeting always ends up on.

What you get is a working Dojo, not advice about one. The audit first, where the hours actually go. Then the command center, the trained AI ninjas, the factories behind your repeated work. Every ninja starts at white belt: propose only, prove it, earn the next belt. Nothing sends, pays or posts itself, at any belt, at any price.
And the reason it is priced as a subscription, not a project: a Dojo is not a deliverable, it is a practice. Belts advance, new ninjas join as you grow, and I stay on call as your sensei the whole way.
Monthly subscription. Cancel anytime, effective at the end of the paid month.
I opened my first martial arts school at 19. Today I run NinjaGym on Koh Samui: martial arts for kids, seven days a week, 800+ families. A sensei's whole job is taking someone from white belt to black belt without skipping the proving part in the middle.
I am the nerd who enjoys this part, and I wanted my time back too. So I built the app that runs my gym, then the POS the vendor would not sell me fairly, then the console that runs everything, then fourteen more builds, including the game I had wanted to make for twenty years. It is on the Apple App Store.
Now I do for other owners what I did for myself: I build the Dojo, train the AI ninjas, and hold the one rule that never bends: a human presses every send.
If you have read this far, you have seen the whole story, so let me say the quiet part directly.
I am not a marketing expert and I am not going to become one. I am a sensei who got buried in admin, refused to accept that as the job, and built his way out. The builds on this page are the trail I left doing it.
Somewhere along the way a friend stopped asking me to teach it and asked me to just do it for his company. That request is the entire business model. Most people do not have the time to learn this. Plenty simply do not like computers. And your hours are worth more in front of your customers than in front of a screen.
So that is the trade: I do the AI so you can do the HI. The handshakes, the classes, the room. If that sounds like your situation, the quiz below this letter is the honest way to find out.
No, and that is the point. Only a tiny slice of people using AI will ever touch the builder tools. I build and train the Dojo; you run your business. If you ever want to learn what is under the hood, I will show you, but it is never required.
Never. Every ninja starts at white belt: propose only. Drafts and filings pile up for your review, and a human presses every send, pay and post. That rule does not bend at any belt or any price.
Your Dojo is $2,222 a month: I build it, you run it. Sensei runs it is $4,444 a month: I run the daily work too. Actual product builds, an app, a site, a backend, are separate at $222 per 2-hour block or $2,222 for 20 hours, scoped in writing before the clock starts. Your AI, software and ad accounts stay yours and in your name.
The audit first: we map where your hours actually go, together. Then your first ninja takes the one task that eats the most, usually the inbox, at white belt. It proves itself before anything widens.
Anytime. It is a monthly subscription, and cancelling takes effect at the end of the paid month. The Dojo and everything built in your accounts stays yours; it was always in your name.
Because trust is earned by showing up and proving it, which is exactly how I grade kids at the gym. A ninja that has proven its lane gets a wider one. One that has not, does not. It keeps the honest order: propose, prove, then earn.
Client names stay out of it, and I will not invent a quote to fill a box. What I can show is what was asked for, and what shipped.
"Give me my evenings back."
ShippedThe gym app. 800+ member families, bookings, belts, birthdays, running on auto while the sensei teaches. That client was me.
"Teach us to do what you did." Then: "could you just do it for us?"
ShippedA support desk that drafts a reply to every customer mail for one human press, payment mail that files itself, and an overseer that answers "is everything running?" truthfully, including "no".
"Stop the till charging $5 per staff member for a PIN."
ShippedMy own POS backend. Staff PINs, named transactions, inventory, the books, and more the vendor never offered. A service fee became a system I own.
"Bring a 1998 factory online."
ShippedThe whole front and back office for a commercial air-handling maker: website, backend, QR tracking on the equipment, service management and a CRM. A quarter-century of paper became one system.
When client quotes appear here, they will be real, attributed with permission, and boring compared to the receipts. That is how you will know they are true.
Tell me where your hours actually go. My Ninja Agent reads it first: it answers the basics on the spot, and anything real gets forwarded straight to me. Yes, that is the product, answering its own front desk.
