## What you get
- **Discovery pack** — Domain map, data flow diagram, integration risk register and constraint log. Fixed fee, fixed scope, before any build commitment.
- **Architecture you can read** — Data model, service boundaries, API contracts, RBAC and tenancy approach. Every decision recorded with its rationale and the trade-off accepted.
- **Working software every sprint** — Two-week loops, scope locked at sprint start, senior engineers on every meaningful piece. Debt goes in the backlog with a remediation plan.
- **Hardening and handoff** — Load testing, observability, runbooks and structured knowledge transfer. Two weeks on call after go-live.

## Shape and price

- **Duration** — Discovery 1–2 weeks · Build in 2-week milestones
- **Cadence** — Working software at the end of every sprint
- **Team** — Senior engineer-led, 2–3 engagements at a time
- **Discovery sprint** — Starts from USD 5,000. Fixed fee, fixed scope, credited against the first build milestone. Milestones are priced after discovery. Quoted in AED or INR for UAE and India engagements.

## What this covers
- **Scratch to production** — An idea, a problem or a half-built system. We take it from discovery to a deployed platform your team operates.
- **Platform modernisation** — Migration and rescue of systems that hit a ceiling with a previous team or tool, including CRM stacks such as Bitrix24, with a rollback-safe plan.
- **WhatsApp-native systems** — CRM, booking, dispatch and support that run where your customers already are, on the WhatsApp Business API, with serious engineering underneath.
- **Fractional CTO** — Architecture governance, vendor evaluation, team structure and due-diligence prep for founder-led companies. We own decisions and stay accountable for outcomes.

## How it starts

1. **Book the call** — Thirty minutes. You describe the system and the stakes. We tell you honestly whether we are the right team, even when the answer is no.
2. **Discovery sprint** — One to two weeks with your domain experts. You leave with the discovery pack whether or not you continue with us.
3. **Milestone build** — Scope and price agreed per milestone. Working software every sprint. Hardening and handoff before we call it done.

## FAQ

### What does a product engineering partner do that a dev agency does not?

A dev agency delivers the features you specify. 7Unit owns the outcome: architecture, delivery and the operational handoff. We write the decision log, surface integration risk before build, and stay on call after launch. You are not managing the engineers.

### How much does it cost to build a software platform with 7Unit?

Discovery is a fixed fee with a fixed scope. Build is priced per milestone after discovery, because the architecture decides the cost. We do not quote a platform before the domain is mapped. If your scope is small enough for a no-code tool or a single AI coding session, we say so on the first call.

### How long does a build take?

Discovery takes one to two weeks. Builds run in two-week sprints with working software at the end of each. A contained operational system typically reaches production in a few milestones. A multi-tenant regulated platform takes longer, and discovery tells you how much longer before you commit.

### Can you take over a half-built or legacy system?

Yes. Platform modernisation is one of the modes inside Build. We map what exists, isolate the risk, and migrate with a rollback-safe plan. This includes configured CRM stacks such as Bitrix24 and PHP-era back offices.

### Who owns the code and intellectual property?

You do. Everything delivered under the engagement, source, infrastructure configuration and documentation, is yours. 7Unit retains only its own pre-existing tooling, which is listed in the contract.

### Do you work as a fractional CTO?

Yes, for founder-led companies that need architecture governance, vendor evaluation, team structure and investor due-diligence prep. It runs as a retainer, or as equity for early-stage companies where that fits. We own decisions, not just advice.

### Which stack do you build with?

React and Next.js on the front, FastAPI, Python or Java Spring Boot behind, PostgreSQL with row-level security, Docker and GitHub Actions on AWS, GCP or Vercel. The WhatsApp Business API is integrated directly with Meta. The stack is chosen per system, not sold as a package.
