Prototype Sprint $395 total
The interactive prototype with a fixed total: the $199 build plus 4 weeks of refining at $49 a week, as one number.
Start a Prototype SprintAttainSoft presentsFor founders and small teams
Start here Your idea, on screen, in people’s hands.From a sentence to a product.
Start with a clickable prototype, test a private MVP with invited users, and build the production product when you are ready. We shape it, build it and host it — in English and Spanish.
One main journey at a time — shaped, built, hosted.
- Act oneOne journey worth building first
Tell us the idea
The problem, who it's for, and what you want people to be able to do. We scope one main journey worth building first.
- Act twoA hosted, clickable prototype
We shape and build
You get a hosted, clickable experience — up to five screen templates on the prototype — not a document to interpret.
- Act threeOne revision round a week
Show it and refine
Walk potential customers, partners or investors through it. One consolidated revision round a week while you refine.
- Act fourPrototype → private MVP → production
Graduate when it earns it
Move to a working private MVP with invited testers, then to a production product when you are ready. Each stage is quoted separately.
Start with something to show. Grow into something to run.
Starting prices, with the setup and the weekly cost side by side. Each grows with how many features you need and how complex they are. Each stage says plainly what works and what is simulated.
- Recommended first step
Interactive Prototype
Simulated flows and sample data. Not live business operations.
- Initial
- From $199
- Ongoing
- From $49 / week while refining
Example, not a quote: 4 weeks of feedback = $199 + 4 × $49 = $395.
- Stage 2
Private MVP
Working software with limited scope and access. Real versus simulated behavior is labeled in the order.
- Initial
- From $1,999
- Ongoing
- From $299 / week after initial build
Example, not a quote: 8 weeks = $1,999 + 8 × $299 = $4,391.
- Stage 3
Production Product
Production engineering, with launch and ongoing responsibilities explicitly scoped.
- Initial
- Custom quote
- Ongoing
- Custom
You approve a written quote before any payment. The $199 or $1,999 is charged when you approve it, with no separate deposit.

AI-built app readiness audit $299 fixed
Started an app in Lovable, Bolt, Replit or a similar tool and got stuck at login, payments or launch? We review it and give you a written, ranked list of what breaks and what it takes to fix it.

Attain OS is the platform we designed and built: 19 built-in apps, one AI agent across four channels, one shared database — live in production, in beta, in English and Spanish.
Read the case studyQuestions founders ask first.
Can I show the demo to investors or partners?
Yes. Use the hosted prototype or private MVP to explain your idea to potential customers, partners or investors. Arrange demo access under your project's sharing rules; funding and investment outcomes are not guaranteed.
Can I start without designs?
Yes. Bring the problem, who it is for, and any references you have — brand notes, screenshots, or links. If you have no designs, we recommend a visual direction as part of shaping the prototype. Your actual agreed scope is written down before work starts.
What do I provide?
The audience and the problem, plus whatever you already have: rough flows, brand or design references, and the interactions you care about most. We shape that into one main journey worth building first.
Is a prototype working software?
It is a real hosted interface you can click through and show, built on simulated flows and sample data. It is not live business operations. The private MVP is the stage where agreed core flows actually work, for a small invited group.
Can I charge users on the MVP?
No. The private MVP is for invited private validation — no public commercial launch or live sales. Charging real customers is part of a production product, scoped separately.
How long does a build take?
Delivery time is quoted after we review your scope — we do not publish a fixed calendar here. What we do fix up front is what is included at each stage, so the quote is against something concrete.
Can I skip a stage?
Sometimes — it is an option subject to scope. Many founders still start with a prototype because it is the cheapest way to find out whether the idea holds up. Tell us where you want to start and we will say whether skipping makes sense.
What counts as a software feature?
A feature is one thing a person can do in your product from start to finish, like booking an appointment, getting a WhatsApp reminder or seeing today's sales. It includes the screens, the data and the rules behind it. Simple features (a form that saves details) cost less than complex ones (payments, connections to other systems, AI or real-time updates). Prices start at the amounts shown and grow with how many features you need and how complex they are.
What does the package money actually cover?
See the packages page: the prototype starts at $199 for the initial build and first review, the weekly fee (from $49/week) starts at first-version delivery, and $49/month preservation applies after sign-off at the next billing renewal. The private MVP starts at $1,999 plus from $299/week after the initial build. Prices grow with the number of features and their complexity. Production is a custom quote. New features or a changed core journey are quoted separately.

What are you trying to build?
Describe the problem and who it is for. We will come back with the stage worth starting with and what it would include.
