I'll tell you what's worth building.
Then I build it.

I'm David Cilliers. I work with businesses around Hamilton, Burlington, Oakville and the GTA: working out where AI genuinely helps, training the people who'll use it, and building the thing myself when it's worth building.

Straight answers
including "don't bother"

The short
version.

Before the rest of the page tries to convince you of anything: here is who I work with, how I get paid, and what you are actually holding at the end of it.

Who I work with

Small businesses around Hamilton, Burlington, Oakville and the GTA. Dental and medical clinics, salons, law offices, auto shops, gyms and real estate. Places with no IT department and no spare afternoons.

What I get paid for

Three things: the written assessment, training your team, and the build work when there is something worth building. Never licences, referral fees, or a cut of anything you buy. I do build things, so ask me why I am recommending one. The assessment is priced on its own and names what is not worth building, which means a "don't" costs you nothing and earns me nothing either.

What you end up holding

A written map of a normal week in your business, with every recurring task marked worth automating, not worth it, or leave alone, and a rough cost against each. That document is yours whether you hire me for anything else or not.

Places like this. Not enterprises with an IT department, just people who are good at the thing they do and have no spare hours to spend decoding a sales pitch.
Hype vs. reality

What they promise.
What's actually true.

Pick your trade. This is the kind of thing I'd walk you through, including the parts where the honest answer is "that won't work."

Can AI run a dental practice's front desk?

What you'll get pitched

"AI can run your entire front desk. Patients book, reschedule and get answers without staff touching it."

✕ the pitch
What I'd actually tell you

It can't, and honestly you wouldn't want it to. What it genuinely handles is the repeat typing: reminders, confirmations, rebooking nudges. Start there, keep a person on the phone.

start small, keep the human

Will an AI booking assistant keep a salon's chairs full?

What you'll get pitched

"An AI booking assistant will keep every chair full."

✕ the pitch
What I'd actually tell you

Nothing fills a chair on its own. What changes is speed: a cancellation can reach your waitlist in seconds instead of never. Useful, but it's a timing fix, not a demand fix.

speed, not magic

Can a law firm use AI to draft documents?

What you'll get pitched

"AI drafts your documents now. Cut your admin time in half."

✕ the pitch
What I'd actually tell you

It writes rough first drafts you must read properly, and it will confidently invent a case citation if you let it. Real time saved on summarising and typing. Real liability if nobody checks.

drafts, never final

Should an auto shop automate its quoting?

What you'll get pitched

"Automate your quoting and win more jobs."

✕ the pitch
What I'd actually tell you

A real quote still needs your judgment on parts and labour. What it can do is get a fast, human-sounding first reply out so you're not the shop that answered a day late.

fast reply, your numbers

Can a chatbot answer patient questions for a clinic?

What you'll get pitched

"A chatbot can answer your patients for you."

✕ the pitch
What I'd actually tell you

For hours, parking, forms and what to bring, yes. For anything clinical it needs to hand off to a person immediately. Knowing where that line sits matters far more than which tool you pick.

know where the line is

Can AI stop gym members from churning?

What you'll get pitched

"AI will stop your members from churning."

✕ the pitch
What I'd actually tell you

People quit for real reasons a tool can't fix. What it can do is make sure week-two check-ins actually happen every time, which is where a lot of the quiet drop-off starts.

consistency, not persuasion

No two shops are the same. Which of these is true for yours is what the conversation is for.

How working
together goes.

Four steps, and you can stop after the first one without owing me anything. Plenty of people do.

  1. 01

    A 20-minute conversation

    You walk me through how the place actually runs. I tell you where AI fits, where it doesn't, and what I'd ignore if I were you. Free, and there's nothing to buy at the end.

  2. 02

    A plain-English write-up

    I map a normal week in your business and mark what's worth automating, what isn't, and roughly what each would cost. The document is yours whether you hire me or not.

  3. 03

    I train your team

    A workshop and hands-on practice on the tools your people will actually touch, including what should never be typed into them.

  4. 04

    I build the thing

    When something clearly earns its place, I build it rather than handing you a list of vendors. It gets handed over documented, so your people own it after I'm gone.

I don't resell licences and I don't take referral fees.

I get paid for the work itself, never for what you end up buying. That's why I can tell you a tool isn't worth the money, or that the thing you've asked me to build shouldn't be built. Engagements have an end date rather than a subscription that quietly renews.

The jargon,
in English.

Four words you'll hear in every pitch. Here's what they actually mean, so nobody gets to use them on you.

LLM
The engine inside ChatGPT and the rest of them. It predicts what text should come next, a piece at a time. It isn't looking anything up, which is how it can be fluent and completely wrong in the same sentence.
Hallucination
When it states something false with total confidence. It isn't lying to you. It has no idea. That's the whole reason a person still reads anything before it reaches a client.
Agent
Software that takes several steps on its own instead of answering one question. Genuinely useful. Also where the expensive mistakes happen, because nobody is checking the middle steps.
RAG
Letting it read your own documents before it answers. This is how you stop it inventing details about your business. If a salesperson can't tell you where their answers come from, ask again.
Questions I actually get

The answers,
before you ask.

These are the questions that come up in nearly every first conversation. You don't have to book anything to get the answer, so here they are.

Do I need an AI chatbot for my business?

Probably not yet, and this is the single most common thing I talk people out of. A chatbot solves a volume problem: too many people asking the same question for your staff to keep up with. Most businesses around Hamilton don't have that problem. They have a repetition problem, which is a different thing. If your site gets forty visits a week, a chatbot is answering nobody while costing you a subscription and a fortnight of setup. The reminder calls and the same five email replies your staff retype every day, that's where the time actually goes. Fix that first. If you reach the point where real people are genuinely waiting on answers, then a chatbot earns its place.

Is it safe to put client details into ChatGPT?

Not the free consumer version, no. The consumer tier's terms allow your inputs to be used to improve the model. The business and enterprise tiers have different data terms, and for a law office, a clinic, or an accountant that distinction is the whole ballgame. It's the difference between a normal tool and a confidentiality problem. The practical rule: assume anything typed into a free AI tool has left your building. Before anyone on your team uses one for real work, decide which tier you're on and write down what is and isn't allowed to go into it. That takes about twenty minutes and it's the cheapest risk you will ever remove.

What should a small business actually start with?

Whatever your staff retype most. Nine times out of ten it's appointment reminders or the same five email replies. Boring, small, and it pays back every single week. The reason to start there isn't that it's the most impressive use, it's that it's the one where being wrong costs you nothing. A reminder that reads slightly oddly is a shrug. A quote with the wrong number on it is a real problem. Start where the mistakes are cheap, let your team build a feel for what the thing is actually like, then decide about the bigger stuff. Most people do this backwards and start with whatever is hardest to check.

How much does AI actually cost a small business?

The subscription is the small number, and it's the only one anybody quotes you. Per-seat tools generally run somewhere between twenty and a hundred dollars a month per person. That is rarely what the thing costs. The real cost is the three months your team spends half-using it, the workarounds they build because it doesn't quite fit how you work, and the one person who quietly becomes its unofficial owner. Then there's the afternoon everyone goes back to the old way and nobody says anything, because it was the boss's idea. When I map costs for a business I write down four lines: the licence, the setup time, the training time, and who owns it in six months. If that last line is blank, the tool is already dead.

Will AI replace my staff?

Not in a business your size, and anyone telling you otherwise is selling something. What it replaces is tasks, not people, and specifically the typing-shaped ones. The places I see get real value out of this aren't cutting headcount, they're getting the people they already have out of retyping the same things all day. That said, I'd be lying if I said nothing changes. Roles that are mostly transcription and copying between systems do get thinner over time. If that describes a job in your business, the honest move is to start shifting that person toward the parts of the work that need judgment, rather than waiting to find out.

What is an AI agent, and do I need one?

An agent is software that takes several steps on its own instead of answering one question. Ask a question, get an answer. Ask an agent to do something and it goes away, makes a series of decisions, and comes back when it's finished. That's genuinely useful, and it's also where the expensive mistakes live, because nobody is checking the middle steps. If it gets step two wrong, steps three through seven are all confidently built on top of that mistake. For most small businesses the honest answer right now is no, not yet. Get value out of the simple things first. An agent is what you graduate to once you know what this technology is actually like when it's wrong.

How do I know if an AI tool is any good?

Three questions, none of them technical. Where do the answers come from? If the salesperson can't tell you, the tool is generating them rather than looking them up, and it will invent details about your business. What happens when it's wrong? If the answer is a shrug, you are the one holding that risk, not them. And who on my team owns this in six months? If nobody does, it's already dead. The tool that gets abandoned usually isn't the bad one, it's the one nobody was responsible for. You don't need to understand how any of it works to ask those three, and they sort most of the pitches you'll get this year.

Is AI training worth it for my team?

It's worth it when the alternative is people quietly using these tools badly, which is what's happening in most businesses right now whether or not anyone has approved it. Your staff are already pasting things into ChatGPT. The question isn't whether AI is in your business, it's whether anybody has told them where the lines are. A session covering what the tools do, what they get wrong, and what's not allowed to go into them costs you a morning and removes most of the risk. The other reason is ownership. A tool somebody was taught properly gets used. A tool that was simply installed gets abandoned. That difference is most of the return.

What's the difference between ChatGPT and an AI tool built for my business?

ChatGPT is a general engine. It knows a great deal about the world and nothing about you. A tool built for your business is usually that same kind of engine with your own documents wired in, so it answers from your prices, your policies, and your history. That wiring is the part people call RAG. The practical difference is that a general tool will confidently invent details about your business, and a properly connected one won't, because it's reading rather than guessing. Whether you need the second kind depends entirely on whether the answers have to be specifically right. For drafting a supplier email, no. For anything a customer relies on, yes.
