How it works
A lane is one thing we’re building at a time.
That’s the whole model. You keep the queue full. We keep the lanes moving. The number of lanes sets the price.
The rhythm
What working with us actually feels like.
You set the order
Once a week we go over what’s being built and what’s coming next. If your priorities have moved, you reorder the queue. Reordering takes a message, not a meeting.
The lane keeps running
A fleet of AI agents does the building: writing, testing, reviewing, rewriting. A human who has been building software for twenty-five years reads that work and steers it, every day. There is never a week where nothing of yours is being worked on.
The work comes back finished
Things land when they’re genuinely done, not on a schedule that forces us to call something finished when it isn’t. In the meantime you can see and try the real thing as it comes together. You tell us what’s wrong; it goes back in the lane. When it’s right, the lane picks up your next idea.
How long it takes
Something useful in days. Better every week after that.
“How long does a customer portal take?” is the question everybody asks, and the real answer is that it depends on what you mean by finished. A portal can grow for years. So we answer a more useful question instead: how long until your customers are logging into something real. That answer is days.
We build the smallest version that does actual work, and we build that first. Not a mockup, not a prototype you throw away. The real thing, doing the most valuable part of the job, in your hands while the rest is still being built. Everything after that is improvement on something already earning its keep.
And before a lane starts, we tell you if what you’ve asked for is too big. If it can’t be phased into something useful quickly, you hear that up front, along with how we’d break it up and what the first piece would be. Nobody finds out in month four that they bought something that was never going to land.
The queue
Adding an idea costs you nothing.
Send it the moment you think of it. Half-formed is fine. “Someone in accounting spends every Thursday afternoon on this” is a perfectly good starting point, and we’ll ask the questions that turn that complaint into something we can build.
The queue has no limit and no cost. What it has is an order, and the order is entirely yours. Something urgent came up? Move it to the front. The request you made last month doesn’t matter anymore? Delete it. Nobody writes any paperwork, because there was nothing agreed in advance to change.
Keep in mind: a long queue doesn’t make the work go faster. One lane builds one thing at a time. Adding your tenth idea doesn’t slow down the first nine. The tenth one simply waits longer. If the waiting starts to hurt, that’s the signal to add a lane, and we’ll tell you when we see it rather than letting you wonder.
Capacity
Start with one. Add lanes when the queue starts to hurt.
Everyone starts at one lane. One lane is almost always more software than the company managed to get built in the whole year before, and it costs less than the planning phase of a normal project.
Who does the work
Agents build the software. A human answers for it.
We are not pretending otherwise: we get this much done by running AI agents side by side, and that is exactly why the price works. In 2025 the numbers on this offer wouldn’t have added up. Technology advances and you benefit from it.
What the agents don’t have is judgment about your business, a sense of what “good enough” means, or accountability when something breaks at 4pm on a Friday. The human supplies all three, and that judgment is the part you are actually buying. Every lane has one, reading the work, rejecting what is wrong, and answering for what you end up with.
If you want to understand how we think about building systems like this, we write about it at length.
Questions
The things people ask on the first call.
What counts as one thing?
Roughly: a piece of software you’d describe in a sentence and recognise when you saw it. “A page where customers check their order status.” “Keep our inventory numbers matching between the warehouse system and the accounting system.” If one request turns out to really be five, we’ll say so and help you decide which part goes first. Guessing wrong costs you nothing.
How long does something take?
The more useful question is how long until you have something you can use, and that answer is days. We build the smallest version that does real work first, you start using it, and it improves every week from there. A customer portal might keep growing for a year, but your customers should be logging into something real within the first week or two.
If a request can’t be phased that way, we tell you before the lane starts rather than letting you find out later. And anything waiting on a system we can’t get logins for takes exactly as long as it takes to get us those logins.
What if what we want is too big?
Then we say so before the lane starts, and we show you how we’d phase it. Usually “too big” just means it needs to arrive in pieces, and the first piece is still days away rather than months. Occasionally it means the thing genuinely isn’t a fit for a lane at all, and we’ll tell you that too. What we won’t do is take the money and let you work it out in month four.
What if we don’t like what you build?
Tell us, and it goes back in the lane. There’s no extra bill and no argument about whether the change was included, because that isn’t how you’re charged. The only real cost of a wrong turn is that everything behind that request waits a little longer, which is a far better incentive for us than getting paid to build the same thing twice.
How much of our time does this take?
Plan on a couple of hours a week from one person who can make decisions. The usual way these engagements go wrong isn’t us building too slowly. It’s a question of ours sitting unanswered for nine days. RIVVIR can become an integral part of your team.
Can you work on software we already have?
Yes. Most lanes are a mix of new things and changes to software you already run. If a system is genuinely too fragile to touch safely, we’ll tell you instead of quietly making it worse.
Who owns it?
You do, the whole time. The code sits in an account belonging to your company; the hosting and AI services are in your name and billed to you directly. There is nothing to hand over at the end, because we were never holding anything.

Tell us three things you wish you could build.
We’ll tell you which one we’d build first, and roughly how long it would take. Twenty minutes, no slideshow.
