Custom software development

The project you shelved is affordable now.

Start with the stage your idea needs: a clickable prototype, a working private MVP, or a custom production build. Prototype and private MVP packages help you validate the idea; public commercial launches are scoped separately.

The problem

You scoped it. You got the quotes. You shelved it.

The internal tool everyone works around. The client portal your customers keep asking for. The product idea that needed a technical cofounder you never found. Each one came back priced like a construction project and timed in quarters, so it went on the shelf. That math was real. It's also out of date.

Most of the quote wasn't your product

Login, roles, permissions, notifications, an audit trail, a mobile layout, a second language. Every from-scratch build pays for that plumbing before it builds one thing that is specific to you.

Quarters carry their own cost

A timeline measured in quarters means requirements drift, the sponsor changes, and what finally arrives answers a question the business stopped asking two quarters ago.

Bring back the list

The internal tool, the client portal, the ops dashboard, the idea still sitting in a drawer. Pull out the things you decided you couldn't afford — most of them have changed columns.

What you get

The math changed. Here's what changed it.

Two things at once: a foundation where the unglamorous parts are already solved, and AI-assisted development on top of it.

Day one is not an empty repository

Authentication, roles and permissions, the shared data model, notifications, transactional email, a mobile-ready PWA shell, English and Spanish — these are patterns we have built and run in production. Your build starts above that line instead of paying to draw it again.

AI-native development, not AI-flavored marketing

We build with AI in the loop across the work itself: scaffolding, tests, migrations, and the repetitive middle of every feature. It compresses the parts of a build that were always expensive and never interesting.

You're funding the last mile

The part that is actually yours — your workflow, your rules, your customers' experience. That's where the weeks go, and it's the only part nobody has built before.

How it goes

From an idea you shelved to software people use.

  1. 1

    Map and cut

    First week

    We map the workflow and cut the scope down to the version worth shipping first. Most shelved projects were scoped far past the release that would have proved the point.

  2. 2

    Stand it up

    Weeks two to four

    The foundation gets configured to your data model and your roles, and the first real screens appear. You are clicking through your own product early, not reading about it.

  3. 3

    Build the part that's yours

    The bulk of the work

    Your workflow, your rules, and AI wherever it earns its place. You see it weekly and change your mind while changing it is still cheap.

  4. 4

    Ship, then keep going

    Ongoing

    A private MVP goes to an invited test group without public commercial sales. A production launch follows its own agreed readiness checks and operating plan.

The difference

Traditional build vs. AI-native build.

What mattersTraditional buildAI-native build
Time to working softwareQuarters, then a launch date.Weeks to something you can click, then iterations.
What exists on day oneAn empty repository and a discovery phase.Auth, roles, data model, notifications, mobile, EN/ES.
Cost of changing your mindA change request against a signed spec.A conversation, because you're seeing it weekly.
What you're paying forRebuilding the plumbing, then your product.Your product.
When you find out it's wrongAt delivery.In the first weeks, while it's cheap to fix.
A second languageA localization project after launch.In from the start.

No figures here on purpose. What changed is the shape of the engagement, and that's the part you can check.

The proof

Attain OS — the scale this approach reaches.

Attain OS is a multi-tenant platform we designed and built: 19 built-in apps across four connected domains, all on one shared database, with Atty — the AI agent — working across chat, voice, WhatsApp, and document analysis. It is a real-time PWA, fully bilingual down to the agent and the transactional email, live in production, in beta, on React, TypeScript, Firebase, and Cloud Functions. Every part of the foundation your build starts on already runs in Attain OS.

Is this a fit?

A good fit when

  • You've been putting off building an internal tool or product because quotes come back in quarters, not weeks.
  • Your team built a working process out of spreadsheets, and it's now too important to leave there.
  • You'd rather see the thing early and change it than approve a document and wait.

Not a fit when

Not a fit if you want a 200-page specification built exactly as written with no contact until delivery. We ship working software early and change it with you — if that isn't how you want to work, we're the wrong shop.

Questions we hear about new builds.

Do you build an MVP or app prototype for startups?

Yes, both. A prototype starts at $199 for the build, plus from $49/week while refining. A private MVP starts at $1,999, plus from $299/week after the build, and it is a working product for a small invited test group, not public commercial sales. Production has a custom quote. You can start from a rough idea rather than a spec, and every build can ship in English and Spanish.

What does a build cost?

A prototype starts at $199 for the build, plus from $49/week while refining and $49/month preservation from the next renewal after sign-off. A private MVP starts at $1,999 plus from $299/week after the build. Both grow with the number of features and their complexity. Production has a custom quote. See our packages for the included scope; final terms are agreed before work starts.

How long does a build take?

Timing depends on the stage, agreed scope, integrations and feedback. We agree on a delivery plan before work starts. Reusing established components helps, but it is not a fixed delivery-time promise.

What happens after launch?

You own the code and designs we make for you; the shared foundation behind Attain OS stays with AttainSoft and is licensed to you while we host your build. You can cancel with 30 days' notice, and we export your code and data within 30 days, then delete the hosted copy. Prototype preservation keeps the approved version available for $49/month after sign-off at the next renewal; private MVP hosting starts at $299/week after the build, depending on the feature set. Production operations have a separate scope.

Can you start from a rough idea rather than a spec?

Yes, and that's the more common starting point. Bring the problem, the workflow, and who it's for. Writing the spec is part of the mapping work, and it's far cheaper to write it against something you can click than against a blank page.
