ENGAGEMENT MODEL

STACK18 ENTERPRISE

Purpose-built
software, delivered
and operated for you.

A dedicated Stack18 team designs, builds, hosts, and maintains software built around how your organization actually works — under the governance, security, and audit requirements your industry enforces. You keep the business logic and the decision rights; we run the stack.

Engagement
Dedicated delivery pod, named owners
Ownership
Built, hosted & operated by Stack18
What you keep
Source code, IP & decision rights

BUILT FOR ORGANIZATIONS WHERE SOFTWARE FAILURE HAS REAL CONSEQUENCES

Healthcare Financial Services Manufacturing Government & Public Sector Regulated Enterprise

Everything it takes to ship and run production software.

One engagement, one accountable team. Nothing you have to separately staff, integrate, or chase.

Delivery team
Dedicated pod with named owners, not a rotating bench
Scope
Full lifecycle — discovery through operate, on the same governed pipeline as Stack18 Platform
Infrastructure
Hosted and operated by Stack18, or deployed into your own cloud environment
Security review
Architecture and access review before any code reaches production
Reporting
Weekly syncs, a shared roadmap, and a live audit trail you can open any time
Support
SLA-backed response times, defined in your statement of work
Ownership
Full source code, IP, and documentation, transferred on completion

§01 — HOW AN ENGAGEMENT RUNS

From first call to a system you own.

The same four-layer pipeline that powers Stack18 Platform, wrapped in a managed engagement with named humans accountable for every step.

01

Discovery call

~1 week

We learn how your organization actually works today — the systems, the constraints, the people who have to sign off. No SOW gets written before this happens.

02

Scoping & statement of work

1–2 weeks

A written scope, timeline, and price — reviewed against your procurement and security requirements before anyone signs.

03

Kickoff & discovery layer

2–3 weeks

Your delivery pod is named. Business discovery and requirements gathering produce a signed PRD before design work starts.

04

Design & build sprints

Scoped to the build

Architecture, UI/UX, and code generation run in sprints with weekly syncs and a live roadmap. Every layer ends with your sign-off before the next one loads.

05

Launch & handover

1–2 weeks

Production deployment, documentation, and a full IP and knowledge transfer to your team — or straight into ongoing Stack18 support.

06

Ongoing support

Optional, ongoing

Monitoring, maintenance, and a continuous improvement roadmap under an SLA — or we step back once your team is ready to run it alone.

§02 — YOUR DELIVERY POD

Named people, backed by the full agent roster.

Every engagement is led by people you can call, not a ticket queue. They direct the same nine specialized agents that power Stack18 Platform.

Lead

Engagement Lead

Your single point of accountability — owns the roadmap, the relationship, and every commitment.

Architecture

Solutions Architect

Designs the system against your constraints, your compliance needs, and your existing stack.

Delivery

Delivery Manager

Runs the sprint cadence, the weekly sync, and keeps the roadmap honest.

Assurance

QA & Security Lead

Owns the review gates — code quality, security posture, and compliance sign-off.

§03 — SECURITY & GOVERNANCE

Built to survive an audit, not just a demo.

Enterprise engagements run under the same governance model as Stack18 Platform, with additional review built in for regulated environments.

Architecture review

Every system design is reviewed against your security and compliance requirements before build starts.

Access control

Role-based access to code, infrastructure, and data, scoped to what each person and agent actually needs.

Full audit trail

Every decision, from requirement to deployment, is logged and traceable — reviewable at any time, not just at handover.

Data handling

Your data stays in the environment you specify. Nothing leaves your infrastructure without a documented reason.

Incident response

A defined escalation path and response times, agreed in your SOW before the engagement starts.

Offboarding

A documented exit plan from day one — code, infrastructure, and knowledge transfer, whenever the engagement ends.

§04 — ENGAGEMENT MODELS

Three ways to bring Stack18 in.

Every model runs on the same governed pipeline and the same delivery pod structure — the shape changes to fit what you're solving for.

§05 — WHAT YOU OWN

Nothing you build with us stays with us.

Source code
Full repository access from day one, full ownership on completion
Documentation
PRDs, architecture diagrams, and runbooks — yours to keep and extend
Infrastructure
Deployed in your cloud account, or transferable on handover
Vendor lock-in
None by design — standard languages and frameworks, no proprietary runtime
Exit
A documented offboarding plan, agreed before the engagement starts

§06 — QUESTIONS, ANSWERED

FAQ

How long does a typical engagement run?

It depends on scope. A focused rebuild might run a few months; a full platform build or an embedded, ongoing pod can run for years. Timelines are set during scoping, before anyone signs a statement of work.

Can you work inside our existing cloud environment?

Yes. We can deploy into your AWS, Azure, or GCP account under your existing controls, or host it ourselves if you'd rather not run the infrastructure. Either way, it's specified in the SOW.

How does pricing work?

Enterprise engagements are scoped and priced individually based on the size of the team, the length of the engagement, and how much of the stack you want us to run versus hand over. We'll walk through this on the discovery call.

What happens to our data?

Your data stays inside the environment you specify. We don't move it anywhere without a documented reason and your sign-off, and access is scoped to exactly what the engagement requires.

Do we need our own engineering team for this?

No — the delivery pod covers the full lifecycle. If you do have an internal team, we can work alongside them, hand off cleanly at any layer, or run entirely independently. It's your call.

What happens after launch?

You can take full ownership and run it with your own team, or keep Stack18 on under an SLA for monitoring, maintenance, and continuous improvement. Both paths are planned for from day one.
