Types we build
Six kinds of product, each built around one job
- 01
AI feature inside your app
An assistant or search in your product, with limits on what it can do.
Build this agent- User asks
- Feature answers within limits
- Edge case goes to a person
Example workflows
- A help assistant that answers from your help centre and sends refunds for approval.
- A recommendation panel that explains each suggestion and logs what it showed.
- 02
SaaS platform
A multi-customer product with accounts, billing and AI built in.
Build this agent- Customer signs up
- Product runs the workflow
- Owner reviews usage
Example workflows
- A scheduling platform for clinics with an AI intake step that staff review.
- A reporting tool where AI drafts summaries that users edit before sharing.
- 03
MVP
The smallest version that proves one job with real users.
Build this agent- Scope the one job
- Prototype with users
- Decide to build or stop
Example workflows
- A quoting tool tested with a small group of pilot customers before the full build.
- A matching product tried in one market before it is built out.
- 04
Internal tool
An admin console or ops tool your team uses every day.
Build this agent- Staff request
- Tool drafts the action
- Staff approves in the console
Example workflows
- An ops console that queues AI-drafted replies for a person to approve.
- A finance review screen that flags mismatches and logs each decision.
- 05
Customer portal
Customers see their own data and actions, and every change is written to the audit trail.
Build this agent- Customer signs in
- Portal runs the request
- Change recorded in the audit trail
Example workflows
- A portal where customers check orders and request changes, with each change logged.
- An account page where billing edits are approved by staff and logged on the record.
- 06
Data sync
Keeps your product in step with the systems it depends on, with checks on every sync.
Build this agent- Source changes
- Sync checked
- Failed sync held for review
Example workflows
- A nightly sync between a CRM and billing that holds mismatched records for review.
- An inventory feed that logs every update and flags gaps before they reach customers.
Where products stall
Four points where custom AI products go wrong
01
The AI feature works in the demo and breaks with real users
- Agent does
- Each AI feature ships with guardrails: limits on what it can do, a fallback when unsure, and a log of every answer.
- Person approves
- Any action that changes money, data or access.
BeforeAfterDemo data is clean and short. Real users ask strange questions, and nothing stops a wrong answer reaching a customer.
- Demo answered every question cleanly
- Live users asked things the demo never covered
- A wrong answer reached a customer, with no log
In-app assistantRefund my last invoice.
Invoice found. The amount is above the self-serve limit, so I have sent it for review.
Guardrail: refund over limitheldSample data. Representative workflow, not a client screenshot.
02
The prototype works, but nobody can maintain it
- Agent does
- The build includes an admin console, request logs and documentation, so your team can see what the product is doing.
- Person approves
- Changes to the production system and releases.
BeforeAfterA prototype built in a rush has no monitoring, no admin view and no record of why decisions were made.
- Prototype built in a rush, no monitoring
- Only the original developer knows how it works
- Every change takes a week because nothing is documented

03
Build or buy is a guess
- Agent does
- Each phase starts by testing whether a custom part is needed, so you only build what an off-the-shelf option cannot do.
- Person approves
- The decision to build a custom part, phase by phase.
BeforeAfterOff-the-shelf tools fit most of the job, then fail on the one part that makes your product different.
- Off-the-shelf tool fails on the one feature that matters
- Custom part was never scoped separately
- Rebuild decision made after the budget is spent

Nobody knows what it will cost or how long it will take
- Agent does
- Work is split into phases. Each phase has a fixed price and a written scope before it starts.
- Person approves
- Each phase price and scope, before the phase starts.
BeforeAfterOpen-ended quotes hide the risk, and the budget runs out before the product is useful.
- Quote arrived as one open-ended number
- Scope changed twice with no written record
- Budget gone before the product was useful

Questions buyers ask
Before you scope a project
- What is custom AI software development?
- It is building software where an AI model is part of the product itself: an assistant inside your app, a recommendation engine, an automated review step, or a full SaaS platform. You own the code, the models and the data.
- How is an MVP different from a full product?
- An MVP tests one core job with real users. A full product adds the admin tools, integrations, permissions and monitoring that a business needs to run it every day. We start with the smallest version that proves the job, then add phases.
- Should we build the AI part or buy it?
- Buy the parts that are the same for every business, like email or payments. Build the part that makes your product different. We help you split the two before you spend on either.
- How is the price set?
- Each phase has a fixed price and a written scope that you approve before the phase starts. We do not quote an open-ended project. The first phase covers the written scope before any build starts.
- Who owns the code and the data?
- You do. The source code, infrastructure, models and data are handed over to you, and the handover is part of the written scope.
- What happens after launch?
- Support after launch is a separate phase, scoped and approved the same way as the build.
- What does the audit trail record?
- Every action the system takes: the input, the source or factors used, the output, and who approved it if a person was involved. The trail is kept in storage you control, so your team can answer an audit question from the record.
