Custom software goes wrong in predictable ways
The scope keeps growing. Months pass between demos. The budget runs out before the product is usable. Then the developer disappears and nobody else can understand the code.
We build web apps to avoid each of those traps: a tight first version focused on one core workflow, working software you can click through every week, a fixed price per stage, and clean, documented code in your own repository from day one.
What we build
Customer portals
Let clients log in to see orders, documents, invoices, project status or reports, instead of emailing you for them.
Internal tools
Replace spreadsheet chaos with a simple app for quoting, scheduling, inventory, approvals or job tracking.
MVPs and SaaS products
A first version of your product, with user accounts, billing and the core feature, ready to put in front of real users.
AI-powered apps
Apps with AI features built in: document analysis, chat over your data, smart search or automated drafting. See AI Integration.

How we keep projects on track
Scoping session.
We map your users, the one workflow that matters most and what can wait for version two.
Clickable prototype.
You click through the app in Figma before we write code. Changes are cheap at this stage.
Build in weekly sprints.
Every week you get a working demo link and a short written update.
Test.
Automated tests for critical flows, plus manual testing on real devices.
Launch.
Deployed to your hosting, monitored, with a launch checklist.
Handover.
Code in your GitHub, documentation, environment setup and a walkthrough for your next developer.
What we'll need from you
- A description of the problem, your users and the main workflow
- Any sketches, spreadsheets or existing tools the app replaces
- Access to the services it connects to
- One decision-maker who can review demos each week
Not included
Hosting, database and third-party service fees (paid to the providers in your name), app store mobile apps (ask us about React Native), ongoing feature development after delivery (available as a monthly plan) and penetration testing by a third-party security firm.

How much does custom web application development cost?
Our fixed-price packages start at $1,499 for a focused internal tool, $3,999 for an MVP or portal, and from $7,999 for a SaaS first version. The biggest cost drivers are the number of screens, user roles, integrations and payment logic.
How long does it take to build an MVP?
Most MVPs take around 30 days in our Standard package. Larger SaaS products take 45 to 60 days for a first version. The fastest route is a tight scope: one core workflow, done well.
Who owns the code?
You do. The code lives in a GitHub repository in your name from the first commit, and hosting runs on your accounts.
Can another developer take over later?
Yes. We use mainstream tools (React, Next.js, TypeScript and PostgreSQL) and leave documentation, so any experienced developer can continue the work.
Do you sign NDAs?
Yes. We're happy to sign your NDA before you share details, or provide ours.
