Carpathcode Cluj-Napoca · Romania · EET

The CTO you
don’t have yet.

A written Blueprint, then a fixed-price build.

A network studio for funded seed and Series A founders without a CTO.

You need to ship v1, the board wants a number, and every agency quote is a guess. The Blueprint replaces the guess with a written, fixed price.

One accountable principal in Cluj-Napoca brings in senior specialists per engagement — iOS, backend, web, and design — matched to your scope. Scope, price, and timeline are locked in writing, and the €15,000 credits back in full when you commit.

01First step

A written Blueprint before the Build.

Two to three weeks of paid work. A written technical architecture, scope, role plan, and a fixed price for the Build. Credits one-for-one against the Build if you commit within thirty days.

Deliverable Written document · signed · yours to keep
  1. 01

    Target architecture

    iOS, backend, and web — components, boundaries, and the runtime decisions behind them.

  2. 02

    Data model & integrations

    Schema, third-party APIs, auth, payments, and storage — mapped before the Build starts.

  3. 03

    Role mix & collaborators

    The disciplines your Build needs, named in the Blueprint — with the principal accountable for staffing each one.

  4. 04

    Week-by-week plan

    From kickoff through launch handoff. Milestones tied to outcomes, not stand-ups.

  5. 05

    Risk register

    What could slip, why it would slip, and the mitigation written against each line.

  6. 06

    Fixed price for the Build

    One number. Locked at signature. No surprise re-scoping mid-engagement.

If you don’t commit to the Build, you keep the document. The Blueprint is the cheapest test of whether Carpathcode is the right shape for the problem — before either party signs anything beyond it.

02Fit

Is this for you?

Three honest answers: right fit, alt shape, wrong shape. The Blueprint shows which one applies before any contract is signed.

01 — YesRight fit

Funded seed or Series A. No full-time CTO yet.

A clear product to ship, a board that wants budget certainty, and a launch window the Blueprint can plan against. Comfortable with one accountable principal owning the engagement, with collaborators plugged in as scope demands.

Seed / Series A No CTO Fixed scope Board-ready Blueprint first
02 — MaybeAlt shape

An existing team that needs surge across a single discipline.

A funded company with engineers in place that needs senior iOS, design, or web help for a specific launch window. That is the single-discipline drop, not the full Build — smaller scope, shorter clock, fixed price.

Existing team Single discipline 4–8 weeks Fixed scope
03 — NoWrong shape

Agency-scale enterprise programs or open-ended time-and-materials.

This studio does not run enterprise transformation programs and does not take time-and-materials engagements without fixed scope. The Blueprint will say so out loud if the brief lands there.

Not enterprise Not T&M Not staff-aug
03Phases

Three phases. Each priced. Each gated.

You see the price before each phase and can stop after any of them, keeping everything built so far. Blueprint qualifies the work, the Build ships v1, Embedded runs after launch.

04Process

Four phases, not a stopwatch.

What happens in each phase, what ends it, what handoff looks like. The calendar is locked in the Blueprint, not on this page.

Phase 01
01
Sprint zero. Design system, data schema, API contracts, and scaffolds across iOS, backend, and web stood up in parallel. The phase ends when there is a runnable build on every stack.
Sprint zero
Phase 02
02
Parallel build. iOS, backend, and web features land against a shared schema. Weekly demo on Friday. The phase ends when the feature set agreed in the Blueprint is feature-complete on internal builds.
Parallel build
Phase 03
03
Integration and beta. End-to-end flows hardened across stacks. Closed beta on TestFlight and staging. Performance, accessibility, and store-submission prep happen here, not at the end.
Integration & beta
Phase 04
04
Launch. Store submission filed, production cutover, day-of-launch ops. Repositories, cloud accounts, and the hiring plan handed over to you and your future CTO. Store approval is on Apple’s clock, not the studio’s.
Launch & handoff
05Network

One principal. Collaborators on contract.

Carpathcode is a network studio, not an agency. One accountable principal owns every engagement; senior collaborators plug in where the work demands them.

A single technical principal in Cluj-Napoca owns the engagement, plus collaborators in iOS, backend, web, and design who plug in as the scope demands. The principal is on every call, in every pull request, and accountable for what ships.

Collaborators are senior operators paid as contractors, brought in only where the work requires their craft. There is no junior bench and no project-manager layer. The Blueprint phase decides the role mix and names the people before any of them sign an engagement — and if the right collaborator for a brief isn’t available, the Blueprint says so in writing.

The Build phase invoices once, at the fixed price agreed in the Blueprint. The launch handoff goes to your full-time CTO, not back to the studio — with the repository, cloud accounts, App Store listing, and a written hiring plan for the team you grow next.

06AI loop

What the AI workflow actually does.

The model drafts. The toolchain checks. The engineer decides. Three layers, named tools, no marketing slop.

01 — What the model draftsPair

SwiftUI scaffolds, Codable types, migrations, tests, copy.

An LLM runs in the editor alongside Xcode. It drafts SwiftUI views and view models, Codable types from JSON samples, Core Data and SwiftData migrations, XCTest and Swift Testing cases against acceptance criteria, mock API clients, and the first pass of App Store copy.

Editor pair SwiftUI Codable SwiftData migrations Test cases
02 — What runs on every commitCI

xcodebuild, XCTest, SwiftLint, SwiftFormat, Xcode Cloud.

Every commit is built and tested on Xcode Cloud. SwiftLint and SwiftFormat pass before merge. Unit and snapshot tests catch regressions across the iOS target. Xcode Cloud handles signing, archive, and TestFlight uploads natively — no third-party build glue. A real toolchain tests every build before it ships.

xcodebuild XCTest SwiftLint SwiftFormat Xcode Cloud
03 — What humans decidePrincipal & specialists

Architecture, what ships, the hiring plan, the call when the model is wrong.

Architecture and module boundaries, data flow and Swift concurrency, what makes the cut for launch, store-submission and launch strategy, every line of production code reviewed, and the hiring plan handed to your future CTO — all decided by the principal and named collaborators, never by the model alone.

Architecture Scope cuts Code review Hiring plan Launch strategy
07Rates & ownership

Published rates. Phase-gated. Code you own from day one.

Every engagement shape, what it costs, how it bills, and what transfers when. No surprises after the call.

08FAQ

Common questions.

What funded founders ask before signing the Blueprint. Plain answers.

A thirty-minute call cannot produce architecture, a verified scope, a role plan, or a fixed price. Two to three weeks of paid work can. The Blueprint is a useful artifact whether or not the Build happens, and the €15,000 credits one-for-one to the Build engagement if you commit within thirty days.
A network studio. One accountable principal in Cluj-Napoca owns the engagement end to end, and brings in trusted collaborators on contract where the scope requires their craft. No junior bench, no project-manager layer. The Blueprint names the people for your Build before either side signs for the Build.
The principal, plus the named collaborators from the Blueprint. Collaborators are senior operators paid as contractors, brought in only for the disciplines the work demands — iOS, backend, web, or design. You meet them before kickoff. There is no swap-out to juniors and no offshore subcontracting.
The Blueprint surfaces that gap before any Build contract is signed. Either the principal proposes a collaborator who is a strong fit and you approve them, or the Blueprint declares the brief outside scope and recommends a different shop. Naming the gap early beats faking confidence and shipping a failed Build.
You. Repositories transfer on day one of the Build. App Store listing, signing certificates, AWS or GCP accounts, and domain DNS all sit under your accounts from the start.
The Build is a fixed-scope engagement against the Blueprint. Scope changes inside the engagement are handled as written change orders. Schedule overruns caused by the studio are absorbed; overruns caused by client-side changes extend at the published hourly rate. Phase gating means you can also walk between phases with everything built so far.
The launch handoff includes the running v1, repositories and cloud accounts under your ownership, an annotated architecture document, and a written hiring plan for the team you grow next. The optional Embedded retainer keeps the principal on call while the in-house team ramps.
