Closed beta — access by invitation
Say it, and it exists — your business does more, you don't.
A real application — its own database, its own users, your brand on it. Built here, hosted here, kept developing here.
Then, when you want it different next Tuesday, you say so and it changes. No queue, no quote, no two-week window. You stay at the decisions throughout — nothing is built, published, or changed without your approval.
This form needs JavaScript, which your browser has switched off. Write to hello@runmyb.com with the word waitlist and we'll add you by hand.
You're on the list. What we recorded: your address, the consent wording you agreed to, the time, and a one-word note that you came from this page. Nothing else — no name, no IP address, no tracking.
You won't get a confirmation email. If you want it confirmed, write to hello@runmyb.com and we'll check. If we write, it will be about getting you in — the first thing we ask is what you would build and who it is for, because we let people in one at a time and decide by hand. We can't tell you when, and we won't send anything else in the meantime.

That didn't go through and it's safe to try again — a repeat submission can't create a duplicate. If it keeps failing, email hello@runmyb.com.
One email address and one checkbox — that is the whole thing we ask for.

Why this is different
Selling platforms move money for a product somebody else built. Site builders make a page about the business you already run. Both of them start from something you do not have yet.
Here, that something is the thing that gets built.
How a product actually gets built here
- You describe it. A conversation, in plain language — what the product should do and who it is for.
- The platform builds and verifies it. Assistants write the application, test it, and give it a brand — either one you already own or one built for it.
- You review it privately. The application runs on a private preview, only reachable by you and the people you share a link with.
- You decide what ships. Publishing, changing, or taking down a product is always your explicit decision — going public is a separate, explicit approval, never a side effect. And every build runs through the platform's own checks before it can be accepted at all.
- RunMyB hosts and runs it — and it stays yours to change. Each application gets its own isolated database and its own sandboxed runtime; you configure no servers. And the part nobody tells you about: when you want it different, you say so and it changes. That is not a support ticket and it is not a new statement of work.
Every change re-earns the whole thing — not just the part you changed. You describe the change in plain language; the platform makes it, then puts the whole build back through the same floor it had to pass to exist at all. It must serve, load and not crash; if it stores data it must survive a write, a restart and a read-back; if it has end-user accounts it must pass a seven-item authentication floor. Then it stops at your approval gate. That is the failure nobody warns you about: you ask for one change, the login quietly stops working, and nobody notices for a week. It is a floor, not your specification — the rule you added last month is yours to check at the gate, which is why there is a gate.
What a tool is
A race plan generator for a running coach. A meal plan generator for a dietitian. An exercise prescription tool for a physiotherapist. A career change assessment for a consultant. A mortgage affordability calculator on a broker's site. A skin type quiz that returns a personalised routine. None of these is a page about you; each one is a thing your client opens and uses.
An AI website builder gives you pages, and a page cannot compute. If your clients need something that takes their inputs and returns an answer — a plan, a quote, a score, a schedule — that is software, not a site.
Pick the one closest to yours and picture it live at an address you can send a client to, carrying your name, taking their inputs and giving them back an answer that is about them. Your method keeps working on the days you cannot.
Who builds things here
People who know something worth paying for. A coach, a consultant, an independent specialist, someone selling what they know to a list they built. You have a method and an audience, and everything you can buy will host a PDF or a course — none of it will build the actual tool your clients would use. More for experts →
People with an idea and no way to build it. You can describe the product exactly. Every route to it runs through someone who only gets paid if you proceed. More for founders →
Firms whose real system is a spreadsheet. The file that runs the business. One person understands it, no two people can edit it at once, and nobody will approve a project to replace it, because it works. More for firms →
People whose diary is already full. A dog trainer, a mobile notary, a driving instructor, a professional organiser. You are not looking for an audience — you have clients, by name, who already pay you. What you need is a tool pointed at your own delivery: the intake you re-key, the plan you write by opening last month's file, the report you assemble on a Sunday.
And if you have none of that yet — no method, no idea, no audience, and no evenings to spare — there is an honest page about whether this is for you, written to help you decide against us if that is the right answer.
What the platform does
Not a roadmap. This is what it builds and runs.
- Builds web applications from a description — static sites and tools, applications with their own database, and applications with their own end-user accounts.
- Gives each application its own isolated database and its own sandboxed runtime, with outbound access only through governed, metered doors.
- Creates a brand for a product, or imports one you already have, and builds to it.
- Keeps developing a product after it is built — changes, re-verification, and updates to a running application.
- Previews a finished application privately, and publishes it publicly at an address you can send people to, once you approve it.
- Keeps an interlinked record of what was decided and why for each product, so plans and reasons survive between sittings instead of being re-explained every time.
- Checks that work can be paid for before it starts, and pauses at a ceiling instead of dying halfway through a change.
Add those up and it means one thing: you build the whole product, not a demo of it — your database, your end-user accounts, your brand, running at an address you can send people to.
What stays yours
Your method is yours. To have something built you have to describe how you actually work. We will not use that description to build a product that competes with yours, and we do not train models on your content. Both are written down, not just said — see Terms §10.1 and §10. What we cannot promise, and say so in the same clause: your idea is not made exclusive, and someone who independently describes something similar may get something similar.
Your customers are yours. If you bring clients here, we will not market to them and we will not approach them with an offer that goes around you (Terms §10.2).
Your exit is yours. A product's code exports to your own GitHub or GitLab whenever you want it — the code was already yours; export changes where it lives (Terms §12.1). Test that early rather than when you are angry.
Ask any agency or builder to put either of those in writing before you describe your idea to them.
What's on offer right now
Being early is worth something specific here. The earlier you are here, the easier you are to see. Plan your own way of reaching people; if ours starts working, it is an advantage on top, not the plan.
Joining costs one email address. No account, no call, nothing to cancel later — and the form itself asks nothing about your idea: the built capture carries no field one could go into, so that part is checkable rather than promised. RunMyB is in closed beta and access is by invitation only. If we write, it will be to ask what you would build and who it is for — we let people in one at a time and we decide by hand. Nothing else: no newsletter, no product mail, and no confirmation message today. We can't tell you when, or promise it will be you.

The questions that actually stop people
What happens to my email address?
It goes into one table, with the wording you agreed to and a timestamp. We use it for one thing: talking to you about access to the beta. If we write, the first thing we are likely to ask is what you would build and who it is for — we let people in one at a time and we decide by hand, and we would rather tell you that here than surprise you with it. We don't sell your address, we don't put you on a mailing list, and we don't use it for anything else. The only companies that touch it are the infrastructure providers we run on, named in our Privacy Policy. Changed your mind? Write to privacy@runmyb.com and we'll take you off the list.
Will I get a confirmation email?
No. If you want it confirmed, write to hello@runmyb.com and we'll check.
Who owns what gets built?
You do. The code, the brand, the data — and no model training on your content. That's written down, not just said: Terms §10 and §11. Your product's code exports to your own GitHub or GitLab whenever you want it — what travels is the current code, not the build history. The long answers: Answers.
Do I need to be technical?
No. You describe what the tool should do and who it's for, in plain language, and you make the decisions a client makes — what it does, what ships, what changes. If you have no idea, no audience and no evenings to spare, read starting out first; it's written to help you decide against us if that's the right answer.
Why is there no price on this page?
RunMyB is in closed beta and access is by invitation, so nobody here is being quoted anything. You will see a price before you're ever asked to pay anything.
What this is for, and what it is not
This builds the application that does not exist yet — the tool your clients open, the thing your firm actually runs on. It is one line item, not your stack: your accounting system stays where it is. What gets built runs in a browser; there are no phone apps here, so if your users are standing in a yard with gloves on, say so before you start. And we promise you no traffic — finding buyers stays yours, and we send you nobody you did not bring.
The company behind the platform is RunMyB, Inc., a Delaware corporation — file number 10692576, incorporated July 2026. You can look it up in the state registry yourself; there's more on the company page.

What email will you get from RunMyB?
Everything RunMyB sends is first-party account and transactional mail, from two domains the company owns and operates: mail.runmyb.com for the platform's own account, billing, and security mail, and mail.runmyb.app for the sign-in and account mail of applications hosted here. We are not an email service provider: the templates are the platform's own, we send no marketing mail, and no third party sends through our domains. The detail — what each stream sends, how we handle bounces and complaints, and how to stop mail or report abuse — is on Email from RunMyB.
