Custom app development
A studio service
Built for the brief, not the template.
When no existing platform fits your differentiating logic, a custom build is the only answer. We scope it, design it, and deliver it at a fixed price — no estimates, no drift.
N° 01What custom means
No template. No compromise
Off-the-shelf platforms are optimised for the median use case. When your differentiating logic sits outside that median — a proprietary matching algorithm, a novel data model, a workflow no SaaS tool supports — a custom build is not a luxury. It's the only option that works.
We start from a blank canvas and scope every component to the problem at hand. Nothing is added because it was easy to include. Nothing is omitted because it was hard to build.
N° 02What we build
Greenfield products and replacements
01
Greenfield SaaS
New products where no existing platform fits. We scope the MVP, design the UX, build the core feature set, and hand you a production-ready codebase.
02
Legacy replacement
Ageing internal tools, monoliths that can't scale, or platforms that have become too expensive to maintain. We migrate data, match functionality, and add what the old system never could.
03
Internal tooling
Operator dashboards, admin panels, data pipelines, and the bespoke workflows that keep your business running — built properly instead of held together with spreadsheets.
N° 03Process
Discovery first. Always
Every custom project begins with a structured discovery phase: we map the data model, define acceptance criteria for every deliverable, and lock the fixed price before a line of code is written.
Discovery is not a retainer. It's included in the project fee. You see the full scope document and approve it before we proceed to design.
After discovery: design (wireframes → high-fidelity screens → approval), build (weekly staging demos, async Slack), launch (deployment + 30-day warranty). Every phase is sequential and sign-off gated.
N° 04Technology
Stack chosen for the problem
We don't impose a house stack. We recommend based on your scale, your team's ability to maintain it after handover, and the constraints of the domain.
Common choices: React/Next.js frontend, Node.js or Python API, PostgreSQL or Supabase, deployed on Vercel, Railway, or AWS depending on compliance requirements. Mobile via Swift/SwiftUI (iOS) or Kotlin (Android).
If you have an existing stack you need us to extend, we audit it in discovery and tell you honestly what's extensible and what should be replaced.
Investment
Fixed scope. No drift.
From $24,000 — fixed-scope custom build.
- Structured discovery phase included (not a separate retainer)
- Full scope document approved before build begins
- Weekly staging demos throughout the build
- 30-day defect warranty after handover
- Full source code ownership — no lock-in
- Stack chosen for your problem, not our convenience
Questions
The answers we give most often.
- How is custom development different from your SaaS or mobile offerings?
- SaaS and mobile pages describe the delivery model for known product types. Custom development is for briefs that don't fit a standard category — proprietary logic, unusual data models, or products that cross platform boundaries.
- How do you price a custom project?
- Fixed-scope proposals issued after a structured discovery phase. We define every deliverable, agree on acceptance criteria, and issue a price before work begins. No hourly billing, no estimates that balloon.
- What is the minimum custom project size?
- Our minimum is $24,000 for a focused MVP. Larger greenfield products and legacy replacements typically run $60,000–$150,000 depending on scope and integrations.
- Do I own the code at the end?
- Yes. Full source code ownership, no licence fee, no lock-in. We hand over the repository, infrastructure credentials, and documentation at project close.
- Can you extend our existing codebase rather than starting fresh?
- Yes. We offer extension engagements for existing products. We'll audit the codebase in discovery and give you an honest view of what's worth keeping.
- How do we start?
- Use the contact form to describe the product, your timeline, and your approximate budget. We'll come back within two business days with a scoping call invitation.
