The Market Is Flooded, the Signals Are Misleading
There are more companies claiming to do AI than at any point in history. Most of them are good at one thing: selling.
The pitch is always similar. Transformation. Automation at scale. Cutting-edge models. Proven results. The websites look the same. The case studies sound the same. The promises are identical.
What differs — and what most buyers only discover after they have signed a contract — is what happens when the work actually starts.
A US-based insurance brokerage recently shared this with us: they hired an AI vendor based on a polished demo, paid a five-figure retainer, and eight months later had a prototype that could not handle their actual data format. The vendor's explanation was that the original requirements were "too broad." The demo, it turned out, had been built on synthetic data that looked nothing like the messy, semi-structured Excel exports the brokerage actually used.
This is not an unusual story. It is the norm in a market where the cost of building a convincing demo is extremely low and the cost of building a production system is not.
This post is not a listicle of the "best AI companies." It is a framework for evaluating any AI company you are considering, including us.
Production Deployments, Not Portfolios
The single most reliable signal of a capable AI company is whether they can show you production systems — not case studies, not mockups, not testimonials from unnamed clients. Actual systems, in production, used by real people.
Ask: what AI systems have you shipped in the last 18 months? Who is using them? What do they do? What volume do they handle?
Listen carefully to how they answer. Can they name the client or describe the deployment specifically? Can they explain what problems came up after launch and how they were solved? Can they tell you what the system does when the AI gets something wrong?
A company with genuine production experience talks about their work in specifics. A company that mostly does consulting and demos will be vague and rely on confidentiality as an explanation for why they cannot say more.
Consider what "production" actually means here. A recruitment software company running an AI that screens 4,000 CVs per month has to handle edge cases that a demo never surfaces — candidates who write their experience in paragraph form instead of bullet points, resumes submitted as images, multilingual documents. The engineering required to handle those cases reliably is entirely different from building something that works on a curated test set.
When a company can tell you about the edge cases they encountered, the workarounds they built, and the tradeoffs they made, you are talking to a team that has actually shipped something. When they cannot, you are probably talking to a team that has mostly sold things.
Honesty About Fit
The best AI companies turn down work.
This sounds counterintuitive until you have worked with a company that took a project they should not have taken. The project drags, the output does not meet expectations, and the company's explanation is always some version of "the scope was unclear" or "the requirements changed."
The best AI companies qualify projects rigorously before taking them. They push back when a proposed use case is not a good fit for AI. They ask uncomfortable questions about data quality, about internal adoption, about what happens when the system makes a mistake.
A 12-person law firm, for example, might come in wanting an AI that "reads contracts and flags issues." That use case is real and achievable — but only if there is clarity on what "flagging issues" means, which contract types are in scope, what the output format needs to be for fee-earners to actually use it, and what the firm does when the AI misses something. A company that skips those questions and immediately starts proposing GPT-4 integrations is not saving you time — they are deferring the hard problems until after you have paid them.
If a company says yes to everything you describe, that is not enthusiasm — it is a red flag.
The corollary is that the right vendor will sometimes tell you that what you want is not the right starting point. They might suggest a narrower scope that can be shipped in six weeks instead of six months. They might recommend that you solve a data quality problem before building AI on top of it. That kind of honesty is genuinely rare and genuinely valuable.
Technical Depth Across the Full Stack
AI development is a specific discipline that requires a specific set of skills:
- Choosing the right model for the use case (not always the biggest or most expensive one)
- Designing retrieval architectures that give the model the right information at the right time
- Engineering prompts that produce consistent, structured output
- Building evaluation pipelines that tell you when the system is degrading
- Integrating AI outputs with business systems — CRMs, databases, payment processors, communication platforms
- Designing escalation paths for when the AI cannot handle a situation
- Monitoring production systems so you know what is happening
A company that outsources the engineering to another firm, or that uses off-the-shelf tools without understanding the trade-offs, will not deliver depth. Ask about the actual engineers who will work on your project. Ask what tools they use and why. Ask how they handle model limitations.
For context on what "full stack" actually looks like: a healthcare SaaS company building an AI intake assistant needs the model to handle clinical terminology consistently, the retrieval layer to pull the right patient history without surfacing irrelevant notes, strict output formatting so downstream systems do not break, and monitoring that catches when the model starts misclassifying symptoms. Each of those layers is a distinct engineering problem. A team that is strong at prompting but weak on retrieval or observability will fail at the integration layer, which is where most AI projects actually fall down.
Ask specifically: who on your team has built RAG pipelines before? Who handles evals? Who owns the integration work? If the answer is "we have a flexible team" or "we bring in specialists," dig harder. Dependency on freelancers or offshore contractors for core components is a structural risk that appears at the worst possible time — usually when something breaks in production.
Clear Pricing and Scope
AI projects are genuinely uncertain. Requirements evolve as you learn what the model can and cannot do. Build time is harder to estimate than traditional software because you cannot always predict how much iteration a given AI component will need.
This uncertainty is real. But it is not an excuse for vague pricing or scope that shifts without explanation.
The best AI companies scope projects carefully upfront, communicate what is in scope and what is not, and change orders when scope changes — not after delivery when you are surprised by a number. They work on fixed-price milestones where possible, and on time-and-materials with clear reporting where not.
As a rough benchmark: a focused AI integration — connecting an LLM to an existing business system with a defined set of inputs and outputs — typically runs between $15,000 and $50,000 for an experienced team. A full AI agent with custom workflows, multiple integrations, and production monitoring sits between $40,000 and $150,000+. Voice AI systems tend toward the higher end because of latency requirements and telephony integration complexity. If you are being quoted dramatically below these ranges, ask what is being cut. If you are being quoted far above without a clear explanation, ask what is being padded.
If a company's pricing is entirely "we'll figure it out as we go," be cautious. There is a difference between genuine agility and a lack of estimation discipline.
What Happens After Launch
Most companies disappear after delivery. A payment is made, a handoff happens, and you are on your own.
AI systems are not like static websites. They degrade as the world changes, as your data changes, as the models they depend on are updated. They produce edge cases you did not anticipate. They fail in ways that require a developer who understands the architecture to diagnose.
Consider what this looks like in practice. An e-commerce company builds an AI-powered product recommendation engine. Six months after launch, the model provider changes the underlying model version. Response latency increases, output formatting shifts slightly, and the downstream parser that converts the AI's recommendations into product IDs starts breaking intermittently. If the original build team is not available, you are left with a fragile system that nobody fully understands — and a support ticket queue that is growing.
Ask any AI company you are evaluating what their post-launch engagement looks like. Do they offer ongoing maintenance? Will the team that built the system be available to fix problems? What is the response time when something breaks in production?
Off-the-Shelf vs Custom-Built AI: What the Tradeoffs Look Like
Before evaluating vendors, it helps to know which type of AI solution you actually need. Most buyers default to "custom" when a well-configured existing tool would serve them better — and some buyers accept generic tools when their problem genuinely requires custom engineering.
| Factor | Off-the-Shelf AI Tool | Custom-Built AI System |
|---|---|---|
| Time to deploy | Days to weeks | 6–20 weeks depending on scope |
| Upfront cost | Low to zero (SaaS pricing) | $15,000–$150,000+ |
| Ongoing cost | Monthly subscription, often per-seat | Infrastructure + maintenance retainer |
| Fit to your workflow | Requires adapting your process to the tool | Built around your existing process |
| Integration depth | Limited to provided APIs/connectors | Full integration with your systems |
| Data privacy | Shared infrastructure, data leaves your environment | Can be deployed in your environment |
| Ownership | Vendor controls updates and pricing | You own the system |
| Best for | Defined, common use cases with standard data | Unique workflows, proprietary data, compliance requirements |
A 50-person accounting firm with standard invoice processing probably does not need a custom AI — a well-configured tool like Bill.com or an off-the-shelf OCR service is faster to deploy and cheaper to maintain. A firm handling non-standard documents across multiple entity types and jurisdictions, where classification accuracy directly affects regulatory filings, is a different situation entirely.
What Can Go Wrong: Common Mistakes
The failure modes in AI projects cluster around a few consistent patterns.
Skipping the data audit. The most common reason AI projects underdeliver is that the training or retrieval data is worse than assumed. A professional services firm that wants an AI to answer questions from their knowledge base discovers mid-project that their internal documents are inconsistently formatted, contain outdated information, and have no version control. The AI's answers are accurate to the documents — the documents are the problem. Any serious vendor should audit your data before scoping the AI.
Defining success as "it works in the demo." Demos are optimized for demos. Production systems need to work on the full range of real inputs, not the curated examples that made the presentation look smooth. Insist on an evaluation framework with real data before signing off on any milestone.
Underinvesting in adoption. An AI system that nobody uses has not automated anything. A GP surgery in the UK built an AI that could draft routine referral letters from consultation notes. The GPs did not use it because the system required them to copy and paste text between platforms. Small friction compounds into rejection. The implementation planning needs to include how the AI fits into the actual daily workflow of the people who will use it.
Not planning for the model to be wrong. Every AI system produces incorrect outputs. The question is not whether — it is how often, what kind of wrong, and what happens next. A good vendor will design escalation and review paths into the system from the start. A vendor who tells you the model is "98% accurate" without defining what the remaining 2% looks like is giving you an incomplete answer.
What to Look For in References
References from AI companies are often cherry-picked. Ask for clients you can actually contact, not just logos on a website. When you speak to them, ask:
- Did the project deliver what was scoped?
- Were there surprises in scope or cost?
- What happened when something went wrong?
- Would you work with them again, and why?
Pay particular attention to the last question. Clients who had a genuinely good experience talk about specific things — "they caught a problem with our data before it caused issues" or "they were honest that one feature we wanted would not work the way we expected." Clients who had a poor experience often still say they would work with them again because they do not want to say otherwise. Listen for the specifics.
Also ask specifically about the post-launch period. The project delivery experience and the support experience are often completely different — a vendor can be excellent at building and poor at maintaining. You want evidence of both.

Frequently Asked Questions
How do I know if an AI company actually has production experience?
Ask them to describe a system they have shipped in the last 12 months in specific terms — what it does, who uses it, what volume it handles, and what broke after launch. A team with real production experience will answer with specifics. If they redirect to case study PDFs, cite NDAs for every detail, or talk in generalities, treat that as a signal they are closer to the consulting and demo end of the spectrum than the engineering end.
What should an AI development project actually cost?
Scope determines cost more than any other factor. A focused integration connecting an LLM to an existing business system typically runs $15,000 to $50,000. A custom AI agent with multiple integrations and production monitoring sits between $40,000 and $150,000. Voice AI systems and anything requiring compliance-grade infrastructure tend toward the higher end. Be cautious of quotes far below these ranges — the most common explanation is that post-launch support, monitoring, and edge case handling are not included.
How long does it take to build a custom AI system?
A well-scoped integration can be production-ready in six to ten weeks. A more complex agent or multi-system workflow typically takes three to five months. The largest driver of timeline variance is data readiness — if your data needs significant cleaning or restructuring before the AI can use it, that phase alone can add four to eight weeks. Any vendor who quotes a specific timeline without first auditing your data is guessing.
What is the difference between an AI agency and an AI development company?
In practice the terms are used interchangeably, but the distinction matters. Agencies tend to focus on strategy, implementation planning, and model configuration using existing platforms. Development companies build custom systems — engineering retrieval pipelines, writing integration code, managing infrastructure. For most business use cases that go beyond plugging in a SaaS AI tool, you need development capability, not just configuration expertise. Ask directly: do you write code, or do you configure platforms?
Do I need to provide my own data to build an AI system?
It depends on the use case. AI agents that answer questions from your internal documents, policies, or product catalog need your data to be useful. AI systems that automate a process — routing emails, extracting fields from invoices, generating draft responses — need examples of inputs and outputs to be evaluated against. The minimum bar is usually a few hundred real examples of what good output looks like. If a vendor tells you they can build without any of your data, either the use case is very generic or they are underestimating the calibration work.
What happens when an AI model provider updates their model?
Model providers — OpenAI, Anthropic, Google, and others — update their models regularly, and updates can change output formatting, latency, and behavior in ways that break downstream systems. A well-built AI system isolates the model dependency so that a model change requires only targeted adjustments rather than a full rebuild. Ask your vendor how they version-lock model calls and what their process is for testing and deploying model updates. If they have no process, that is a gap that will cost you at some point.
How do I evaluate whether an AI project delivered what it was supposed to?
Define success metrics before the project starts, not after. Useful metrics are specific: "the AI correctly classifies 92% of support tickets against our five categories" or "draft responses require fewer than two edits per ticket on average." Vague success criteria like "the system works well" or "users are happy" make it impossible to hold anyone accountable. Ask the vendor to co-define the evaluation criteria as part of scoping — any team confident in their output will agree to this without hesitation.
