Contents · 10 decisions

Choose the build before choosing the tools.

The right starting point depends on the job, the ownership you need, and who will keep the system healthy after launch.

01 · The governing principle

Start with the smallest useful solution.

More technology does not automatically create more value. Begin with the least complex system that can reliably improve one business result, then earn the right to add more.

Our rule
Solve the business problem with the lightest system that can be trusted in real work.
  1. 01AutomateKnown steps
  2. 02AssistVariable work
  3. 03ProductizeMultiple users
  4. 04PrivatizeControl required

Each step adds capability—but also cost, testing, maintenance, and operational responsibility. Private infrastructure is a requirement to justify, not a status symbol.

02 · Six implementation levels

Buy a defined outcome, not “AI consulting.”

These offers cover the path from one decision to a complete private platform. A larger number means more scope and responsibility—not necessarily the right place to begin.

03 · Choose by job shape

Automation, assistant, or custom product?

All three can use AI. The difference is how variable the work is, how many people use the system, and how much software must be built around it.

01The steps are already known

Workflow automation

A repeatable trigger starts a defined sequence: move information, update a system, request approval, or send a notification.

Choose it when
The process has a clear start, finish, owner, and expected output.
Example
Route a lead, update the CRM, and prepare a follow-up draft.
Typical entry price
From $2,500
02The work needs language or judgment

AI assistant

A focused AI system researches, drafts, classifies, or answers within a clear job—while a person retains control where it matters.

Choose it when
The task varies each time and cannot be handled by fixed rules alone.
Example
Answer employee questions from approved company sources.
Typical entry price
$10k–$20k
03The system is becoming software

Custom AI product

A complete internal app or customer-facing product with users, permissions, data, multiple workflows, and its own interface.

Choose it when
Several workflows, user types, or product capabilities must work together.
Example
Launch a branded client application with billing and administration.
Typical entry price
From $25,000

04 · Deployment and ownership

Three ways your system can run.

“Owning the AI” can mean owning the project files, the cloud account, the infrastructure, or the model rights. These are different choices.

On a small screen, swipe the table to compare all three options.

Compare managed, client-account, and private deployment
Decision01 · Lowest operational loadManaged and fast02 · More ownershipRuns in your accounts03 · Maximum controlPrivate environment
What it meansEstablished cloud tools and model providers give you the quickest route to a working solution with the least maintenance.The application, workflow, and data are deployed in cloud accounts your company owns and pays for directly.Services run on a dedicated VPS, rented GPU, private cloud, or customer premises when the requirement justifies the added work.
Best forMost first automations, assistants, and early products.Teams that want portability, easier handover, and control over billing and access.Sensitive workloads, dedicated compute, strict data control, or regulated environments.
What you ownYou own your data, project code, configuration, and documentation. Third-party services remain licensed platforms.Your company owns the deployment accounts in addition to the code, data, configuration, and documentation.The client controls the infrastructure and deployment. Model-weight rights still depend on the selected model license.
Main trade-offFastest and least expensive to launch, with recurring provider costs.More control, with more responsibility for access, billing, and operations.Highest control and setup cost, plus an ongoing maintenance requirement.

05 · The technology map

The tools should follow the requirement.

We can work from managed no-code services through to private model serving. The names below are implementation options—not the product you are buying.

01

Connect the tools you already use

Automation and integrations

Move information, trigger actions, request approvals, and keep existing systems in sync.

02

Give your team a focused AI worker

Agent applications

Use a purpose-built interface or configured agent workspace for one clear job and operating boundary.

03

Give the system a reliable place to run

Application hosting

Choose hosting based on interface, API, worker, uptime, region, and ownership requirements.

04

Keep business information organized and recoverable

Data and storage

Design for ownership, backups, retention, permissions, recovery, and appropriate retrieval.

05

Use strong AI without operating GPUs

Managed model APIs

The fastest route to capable models, with data processing governed by the selected provider's commercial terms.

06

Run a model in a controlled environment

Private and open-weight models

Select a model family and serving layer after evaluating quality, license, hardware, latency, and total operating cost.

07

Use dedicated compute when it is justified

Infrastructure and GPUs

A private cloud, dedicated VPS, rented GPU, and on-premises machine provide different levels of control.

08

Know what happened and keep people responsible

Reliability and control

Add logs, quality checks, alerts, access controls, backups, and approval paths appropriate to the risk.

Technology names and logos are trademarks of their respective owners. They identify technologies discussed in this guide and do not imply partnership, endorsement, certification, sponsorship, or affiliation. The final stack is chosen after requirements and license terms are reviewed.

06 · After launch

Decide who keeps it working.

Every production system needs an owner. Choose a clean handover, ongoing care, or an embedded partner before launch—not after the first credential expires.

01

Build and hand over

Included

Receive the project files, configuration, documentation, training, and a clean operating handover.

02

AI Care Plan

From $1,000/month

Monitoring, updates, incident support, and a small allowance for maintenance and minor improvements.

03

Embedded AI Partner

$8k–$15k/month

Ongoing strategy, implementation, experimentation, and improvement with a three-month minimum.

07 · Total cost

The build fee is not the whole operating cost.

A credible proposal separates professional services from provider bills and ongoing responsibility. You should know which costs are fixed, usage-based, and optional before work begins.

  1. 01

    Definition and build

    Discovery, design, implementation, testing, documentation, training, and handover—the professional work covered by our project fee.

  2. 02

    Model usage

    Charges from a managed AI provider, or the GPU time required to run an open-weight model. Cost follows volume, model, and response size.

  3. 03

    Hosting and data

    Application hosting, databases, file storage, backups, network traffic, and any dedicated compute the system needs.

  4. 04

    Connected software

    Licenses for automation platforms, monitoring, communication tools, or business systems that remain third-party products.

  5. 05

    Ongoing operations

    Monitoring failures, renewing credentials, applying updates, restoring backups, and responding when an external service changes.

  6. 06

    Continuous improvement

    Reviewing real usage, correcting weak outputs, adding capabilities, and keeping the system aligned with how the business changes.

Our commercial rule

Our fee, third-party subscriptions, model usage, hosting, hardware, licenses, and ongoing support are shown separately. Where practical, provider accounts are opened in your company’s name and paid directly by you.

08 · Private AI and model adaptation

Self-host because you need to—not because you can.

Private infrastructure can be the right answer. It also transfers more uptime, security, update, and capacity responsibility to your organization.

Self-hosting is worth assessing when
  • Data or contract terms require a controlled environment.
  • A dedicated network boundary or hardware is mandatory.
  • Usage is large and predictable enough to evaluate dedicated compute.
  • A technical owner can operate, secure, monitor, and recover the system.
Managed services are usually better when
  • Speed to value matters more than infrastructure control.
  • Usage is early, low, variable, or difficult to forecast.
  • You want strong model quality without running GPU operations.
  • Your team does not have an infrastructure owner after handover.

Fine-tuning decision

Fine-tuning is step four, not step one.

It can improve a narrow, repeated behavior once the gap is measurable. It does not repair unclear processes, missing knowledge, weak examples, or absent quality checks.

  1. 01Define the task and quality measure
  2. 02Test prompting, workflow, and trusted knowledge
  3. 03Add tools, examples, and repeatable evaluations
  4. 04Fine-tune only if a stable gap remains

Important: Private hosting and fine-tuning are independent decisions. You can privately host a standard open-weight model, or fine-tune a model that is served by a managed provider.

09 · Realistic examples

Four project shapes, with honest ranges.

These examples are planning anchors, not quotes. Final price depends on scope, data readiness, integrations, security, deployment, and the level of operational handover required.
