AI ImplementationAI implementation and custom AI development, one working piece at a time
For clinics, law firms, agencies, SaaS teams and real estate offices: Simon Dziak builds AI for the task that eats the most hours, one fixed-scope piece at a time. Each AI feature or agent starts with a one-page spec you approve and is tested on your own examples before launch; every piece is delivered as code in accounts you own.
A feature or agent that reads, sorts, drafts or answers is the AI Feature or Agent Build, a fixed $2,500 delivered 10 business days after the spec is agreed and access arrives. Connecting two of your systems is the API Integration, a fixed $1,200. For a steady list of AI work on apps and tools you already have, the Monthly Dev Subscription Studio plan is $3,995 a month, one request at a time, delivered as pull requests.

Where AI goes to work
Pick the first piece, then the next
01
Answering leads
Calls, website chat or web forms answered on one channel, the lead qualified and booked, and a person brought in with a summary.
AI receptionist and answering serviceSpeed to lead and missed-call text back02
Automating the work your team repeats
Lead intake, document extraction, email triage, tool syncs and weekly reports, plain code where the steps are fixed and AI only where the input varies.
AI automation services03
AI features inside your app
A clinic’s intake form summarizer, a law firm’s clause finder or a real estate office’s listing reply drafter, built into the web or mobile app you already run.
AI app development and integration04
Agents with limited tools
An agent that looks up a case, a booking or an order through your API and prepares the next step for a person, limited to the actions in its spec, with write actions gated.

How each piece is built
Spec, build, test, hand over
Anthropic’s guide to agents recommends “finding the simplest solution possible, and only increasing complexity when needed”. Each piece follows that: the smallest build that does the job, measured before it goes live.
A one-page spec first
The task, the inputs and outputs, the tools it may call and how success is measured, agreed in writing before any build starts.
Tested on your examples
Each AI feature or agent gets an eval set of up to 50 cases from your own examples, with a scored run before handover, so you see how well it works before your customers do.
Gated writes and full logs
For each AI feature or agent, tool access is limited to the actions you approve, write actions are gated, and prompts, tool calls and token cost are logged.
Handed over in your accounts
Built on your own model provider account and delivered as a pull request with a README and handover notes, so you own the code and the keys.

FAQ
Questions before you start
What do AI implementation services cost?
Each piece has a fixed price. An AI feature or agent is the AI Feature or Agent Build, $2,500, delivered 10 business days after the spec is agreed and access arrives. Connecting two systems is the API Integration, $1,200, delivered 5 business days after API docs and test credentials arrive. Ongoing work is the Monthly Dev Subscription Studio plan, $3,995 a month, sold on its own page rather than in the price box above. Model usage is billed to your own provider account.
What does custom AI development mean here?
Custom code around Claude or Gemini, not a model trained from scratch. It is software around an existing model: the Claude or Gemini API, or another model API you already use, wired to your data and tools with your rules. It does not include training or fine-tuning a model of your own.
Where should a small business start?
With one task your team repeats often, that follows a few clear rules, and where a mistake is cheap to catch. Answering leads, sorting incoming email and pulling fields out of documents are common first picks.
Do I need an AI strategy or a consultant first?
No. Describe the task by email and the scope is agreed in writing before you pay. If you want to talk it through, consultations are paid: $100 per 15 minutes, paid upfront.
How do I know it works?
Each feature or agent comes with an eval set of up to 50 cases from your examples and a scored run before handover. No model is right every time and no accuracy score is guaranteed, so a task where a mistake is costly keeps a person in the loop.
Can a clinic or law firm use it?
Yes, with care. A clinic is usually a covered entity under HIPAA, and whether each model and tool vendor will sign a business associate agreement depends on the vendor and plan. A law firm has its own client-confidentiality duties. The spec lists every vendor that would see client or patient data, and you and your counsel decide before launch. For a clinic or law firm the eval cases are made-up or de-identified unless you and your counsel decide otherwise. This is not legal advice.
Who owns what gets built?
You do. It runs on your own model provider account and is delivered as a pull request to your repository, with a README and handover notes. If you don’t have a repository or cloud account yet, say so when you write in; setting them up is quoted separately in writing.
Who does the work?
Simon Dziak, who founded App369 and built Workspace369’s integrations, background jobs and AI features, does every part of the work.
