Most places to hire AI developers have a stake in who you pick. A marketplace is paid when you hire through it, and a software vendor’s partner list is a sales channel for that software. Many “best AI agency” lists are written by an agency that appears on them. That is fine once you know it. Below are six places to hire AI developers or AI agent developers for a small business, what each is good for, and a job post in plain words that makes the replies easy to compare.
Where do AI assistants send you?
To Upwork, every time. We asked six AI assistants the question in our tracker: “I want to hire someone to build AI for my company. Where do I even start looking?”
| Named in the answer | Answers (of 6) |
|---|---|
| Upwork | 6 |
| Wellfound | 3 |
| 3 | |
| Toptal | 2 |
| Fiverr, Arc, Indeed | 1 each |
| Clutch, DesignRush, GoodFirms (agency directories) | 0 |
Every answer except Google’s AI Mode said to start with a paid pilot, a paid discovery project or a small test project, which is good advice. Only one raised ownership, as a question to ask the builder, and none said the code and the logins should end up in your company’s name. That decides whether you can ever switch builders. Wellfound (three answers) and Indeed (one) are mostly boards for hiring employees. The answers came from ChatGPT with search and Google’s AI Mode as the public products, and from Claude, GPT-6 Luna and two Perplexity models through their developer APIs, between October 2 and 7, 2026.
Which six places are worth a look?
Each place below suits one kind of job, and each has a known way of going wrong.
| Place | Good for | Know this first | What goes wrong |
|---|---|---|---|
| Freelance marketplaces (Upwork, Fiverr, Contra) | One narrow job you can describe in a few lines | The platform is paid when you hire through it. Upwork’s own guide tells you to list AI frameworks, programming languages, dataset size and cloud platform | Dozens of replies from people answering the literal words of your post |
| Vetted talent networks (Toptal, Arc) | An engineer you will direct yourself | They screen for engineering skill, not for knowing your trade | You still need someone in-house who can manage an engineer |
| The partner directory of software you already use | Work inside that one product: your CRM, your automation tool, your AI provider | The vendor sets the bar to get listed. HubSpot lists no freelancers or one-person firms and asks for its certification course. Zapier asks for a business website and an email on your own domain, reviews applications in 7 to 21 business days, and pays partners a commission for new customers they bring | The answer tends to use that vendor’s product, whether or not it fits |
| Your IT provider, accountant or software reseller | A referral from someone who already knows your systems | Most do not build AI themselves; ask who they have seen do it for a client | You get their friend instead of the best fit for the job |
| Free counseling through the SBA (Small Business Development Centers, SCORE mentors) | Working out what to ask for before you hire anyone | Free or low-cost, and local. Counselors vary, so ask whether yours has seen an AI project | Good general advice and no builder at the end |
| Other owners in your trade | A builder who has already done your kind of job | Ask at trade groups, through suppliers, and at the next industry event | The best builder in your trade is booked for months |
OpenAI keeps a partner list too. It listed more than 70 partners when we read it on October 26, 2026, many of them large consulting and IT firms, with no company sizes shown. A listing in any of these directories means a company passed that vendor’s program, which says something about the vendor’s product and little about your job.
A small-business owner who wanted an AI agent built wrote on Reddit in September 2026 that freelancers they had hired on Upwork for other work “fail to show any initiative and are very literal”. A job post that asks for a reply showing how someone thinks can filter out some of those.
What about “best AI agency” lists?
Use them to check a name you already have, not to find one.
Most of these lists are written by an agency that puts itself first; our count is on AI agency vs freelancer vs in-house. A directory with client reviews, such as Clutch, is more useful as a second opinion on a builder someone recommended.
How would Airu Labs answer the post?
The same way you should judge everyone else’s. Airu Labs builds custom AI systems for small and mid-size companies, wired into the software they already use. Send us the same post you send the others, and score our reply on the same five points below.
What should the job post say?
What the job is, in your own words, and what you want back. Skip the technical fields. You do not need to know which model or framework the builder will use; a good builder will tell you. Eight lines cover it:
- The job in one sentence, the way you would say it to a colleague.
- How the work reaches you today (email, text, PDF, a spreadsheet) and about how many a week.
- The software it has to read from or write into.
- Who on your side checks the result, and what they do today when it is wrong.
- What “done” means: it gets your last 30 examples right.
- Who runs it next month, once the builder steps back.
- What you own at the end: the code and every account, in your company’s name.
- What you want in the reply: how they would do it, one system of theirs a company uses today, and what they would build first.
Here is the post filled in for an invented property management company:
We manage 300 apartments with a team of 12. Tenants send about 40 maintenance requests a week by email and text, and our office manager reads each one, logs it in our property software and books a contractor. We want a system that reads each request, logs it, sorts it by urgency and drafts the booking for her to approve. It has to work with our property software and our shared Gmail. She will check every booking for the first month. Done means it handles our last 30 requests the way she did. We want the code and all accounts in our company’s name. Please reply with how you would build it, one system you built that a company uses today, and what you would build first.
Line 8 does most of the work. A reply that only repeats your post with a price has not thought about your job yet, while one that asks what happens to a gas leak reported at 2 a.m. has.
How do you compare the replies?
Send the same post to at least three builders from two different places, then put the replies side by side on five points:
- They said the job back in their own words and asked about at least one thing you left out.
- They asked what happens when the system is wrong, and said what it would hand to a person.
- You know who does the building, and you will talk to that person.
- They named a small first piece and what it would prove on your own examples.
- They said what you hold at the end: the code, the accounts and the logins, in your name.
A builder who scores four or five is worth a call. For the call itself, bring the ten questions for any AI developer. If you are still choosing between a freelancer, an agency or a hire, start with who should build it.
