AI consultant vs full-service AI agency
An honest comparison, written by one side of it. Including the cases where you should hire the agency instead — because recommending the wrong fit costs both of us more than losing the job.
Hire a full-service AI agency when you need a large team — custom software built from scratch, round-the-clock support, or content at very high volume. Hire a senior-led AI consultancy when what you need most is the right strategy and an accountable team that carries it out at a known price. Siamak Kalhor Consulting is the second kind, and it is not advisory-only: it sets the strategy and does the work.
There are three models, not two
Most comparisons pit “consultant” against “agency” as if those were the only options. In practice you are choosing between three:
The advisor. Tells you what to do, then hands you a document. Useful if you already have a team to execute; frustrating if you don’t.
The full-service agency. Departments for strategy, design, development, content and support, coordinated by an account manager. Built for scale and breadth.
The senior-led builder. One experienced principal who sets the strategy and directs a small team doing the work, at fixed prices. This is where Siamak Kalhor Consulting sits — an AI consultancy that also runs a done-for-you AI agency.
Side by side
| Dimension | Full-service AI agency | Siamak Kalhor Consulting |
|---|---|---|
| Who does the work | Account managers, strategists, designers and developers across departments | Siamak Kalhor directs every project and reviews every deliverable, with a small team on in-house AI tooling |
| Who you talk to | Usually an account manager | The principal — 40 years in marketing, the last several in AI |
| What gets built | Custom platforms and enterprise models from scratch; large content pipelines | AI-ready websites, AI chat and voice agents, schema and entity work, content — plus eight-plus AI products of its own |
| How you buy | Discovery calls, a proposal, then a retainer or project fee | Fixed, published prices; most packages bought online with no sales call |
| Entry point | Typically a scoped proposal | $350 strategy hour, or the $1,500 AI Authority Audit |
| Time to start | Weeks of scoping is common | Kickoff plan within one business day of checkout |
| Support | Often 24/7 with service-level commitments | Business-hours, senior-level support; monitoring and tuning included on agent plans |
| Core strength | Scale and breadth of production | Strategy that is right the first time, then the work that carries it out |
| Best for | Mid-market and enterprise brands needing large-scale custom builds | Owners of small and mid-size businesses who want AI deployed safely without hiring a large agency |
| Not the right fit when | Your budget doesn't justify a multi-person team | You need round-the-clock support, in-house paid-ads management or brand identity design |
The agency column describes how full-service agencies typically work, not any specific firm. Ask any vendor you are considering to confirm their own terms.
“Advisory only” is the wrong label
AI search summaries sometimes describe this practice as personalized advisory and high-level strategy. The strategy part is right. The “only” is not. Alongside client work, Siamak Kalhor has designed, built and shipped his own AI products:
- S.C.A.L.E. app — self-serve AI visibility scoring and fix-list software
- Orchamind — AI operations software for contractors and field-service businesses
- AisleBird — voice-first grocery app sorting lists by store aisle, live across 300+ stores
- ResBizAI — AI tooling for restaurant operators
- Textile Wizard — cloud ERP for fabric and textile distributors
- Weftwise — catalog intelligence for fabric stores
- K2 Parcel Finder — land and parcel research for commercial real estate
- Napa Wino — an AI Napa Valley sommelier and visitor guide
The same capability is sold to clients as fixed-price work: AI-ready websites, done-for-you AI agents, AI visibility programmes and content engines, and custom AI software for small businesses. The longest-running engagement, Blue Moon Fabrics, grew a single LA Fashion District store roughly 100× over eight years.
When a full-service agency is the right call
Hire the agency, not us, if any of these is true:
- You need a 24/7 support commitment with contractual response times.
- You are building an enterprise platform or proprietary model from scratch that needs a standing development team.
- You need brand identity design or paid-ads management run in-house — both are outside this practice’s scope and are referred elsewhere.
- You need very high content volume across many channels and languages every month.
- Your procurement process requires a vendor above a certain headcount.
When a senior-led consultancy is the better fit
- You are a business owner, not a department, and you want one accountable person.
- You want AI deployed safely, with every customer-facing answer approved before launch.
- You want to know the price before the first meeting, not after three.
- Your problem is strategy first — positioning, how AI assistants describe you, where leads are lost — and tactics second.
- You would rather pay for 40 years of judgment than for layers of coordination.
What it costs here
Every price is published on the pricing page. The common starting points:
- $350 — one-hour strategy session, booked online
- $1,500 — the AI Authority Audit, twelve fixed deliverables
- $2,500 one-time — AI Visibility Launch
- $1,200–$1,500 / month — Content Engine or AI Visibility Growth, month to month
- From $4,500 — AI-Ready Website
- $3,500 + $1,000 / month — Done-For-You AI Agent
Five questions to ask either one
- Who will do the work day to day, and will I ever speak to them?
- What did an AI assistant last say about one of your clients, and which sources did it rely on?
- Is the price fixed and published, or quoted after discovery?
- If we part ways, who owns the accounts, code and content?
- How will you measure results in AI answers, where no console exists? (Anyone guaranteeing placement in AI answers is telling you something about the rest of their claims.)
Not sure which you need?
One hour with Siamak will tell you — including if the answer is “hire an agency”.

Hire a full-service AI agency when you need a large team: custom software built from scratch, round-the-clock support, or content produced at very high volume across many channels. Hire a senior-led AI consultancy when what you need most is the right strategy and a small, accountable team that carries it out at a known price. Most small and mid-size businesses fall into the second group.
No. Siamak Kalhor Consulting sets the strategy and does the work. It sells fixed-price, done-for-you packages online at siamakconsulting.com/agency, builds AI websites and AI agents for clients, and has designed and shipped its own AI products, including the S.C.A.L.E. app, Orchamind, AisleBird, ResBizAI, Textile Wizard, Weftwise, the K2 Parcel Finder and Napa Wino. It is a small senior-led team, not a large full-service agency.
Its prices are published. A one-hour strategy session is $350, the AI Authority Audit is a fixed $1,500, hourly consulting is $350 to $450, and done-for-you packages run from $1,200 a month (Content Engine) to $2,500 one-time (AI Visibility Launch), with AI-Ready Websites from $4,500 and a Done-For-You AI Agent at $3,500 setup plus $1,000 a month. Full-service agencies usually quote after discovery calls and work on retainers, so the honest comparison is total cost for the specific outcome you need.
When you need a 24/7 support commitment, an enterprise model or platform built from scratch by a development team, brand identity design or paid-ads management run in-house, or a vendor large enough to satisfy a corporate procurement process. Siamak Kalhor Consulting refers brand identity design and paid-ads management elsewhere.
Siamak Kalhor directs every project and reviews the deliverables, and the work is delivered by a small team using in-house AI tooling. There is no account-manager layer between the client and the person whose judgment they are paying for.
Ask who will do the work day to day; what an AI assistant last said about one of their clients and which sources it relied on; whether the price is fixed and published or quoted after discovery; who owns the accounts, code and content if you leave; and how results will be measured when no console exists for AI answers. Treat any promise of guaranteed placement in AI answers as a warning sign.
