Build, buy, or hire: five ways to get AI agents into production, compared
By Krish Subramanian, Chief AI Officer, KOI AI · Published · 4 min read
A mid-market company has five realistic routes to an AI agent in production: build it with its own team, buy a point solution, hire a large consultancy, hire a boutique or a freelancer, or work with a firm like KOI that runs governed agents on its own platform and prices on the outcome. Each is right for someone. The table below says who, and what each costs in time, money, and risk.
The first wave of AI consulting left buyers with a fair suspicion of anyone who says "only we can do this." So this comparison starts from the opposite position: every route below gets a mid-market company to a working agent, and the right one depends on the process, the team, and the sector. KOI is one of the five. Where another is the better answer, the roadmap engagement says so.
| Build in-house | Buy a point tool | Large consultancy | Boutique or freelancer | KOI AI | |
|---|---|---|---|---|---|
| Time to production | Months, after hiring or retraining | Days to weeks, for the workflow the tool covers | Quarters; many engagements end at the pilot | Weeks to months, depending on the person | 4–8 weeks to the first agent; first results by week 2–3 |
| Typical cost | Developer time plus platform costs, ongoing | Subscription per seat or per use | $400–$1,000+ per hour; strategy $150K–$750K | Day rates vary widely; scope often grows | From $50K per use case, fixed against the outcome |
| Who does the work | Your engineers | The vendor's product; your team configures | A rotating team of analysts and engineers | One or two people | The KOI Platform, directed by one senior consultant |
| Governance built in | Whatever you build | The tool's own, usually limited to its workflow | Designed per engagement, at consulting rates | Rarely; depends on the individual | Policy check, named sign-off, accountability ledger, on every deployment |
| Fit with your systems | Exact, if you have the skills | Where the tool integrates; elsewhere, no | Good, at a price | Variable | Inside your CRM, ERP, and communications tools |
| Best when | You have engineers with capacity and the process is core to your product | One well-defined workflow matches a mature tool | Enterprise scale, many functions, a large budget | A small, contained task and a trusted individual | A named process, measurable outcome, and a need for governance without a large budget |
| Watch out for | Opportunity cost; the agent becomes a product to maintain | Lock-in; the second workflow needs a second tool | Decks instead of software; accountability spread across an org chart | Key-person risk; no record when they leave | Not for one-off prompts or work that needs a product, and KOI says so |
Five routes to an AI agent in production, compared on what a buyer decides on.
Build in-house
The right answer when the process is core to what you sell and you have engineers with capacity. The agent becomes part of your product, maintained like one. The risk is opportunity cost: a team that builds an internal agent is not building the roadmap. For back-office processes, finance, compliance, vendor management, service triage, the in-house build rarely pays unless the team already exists.
Buy a point tool
If one well-defined workflow matches a mature tool, buy it. Help-desk triage, expense capture, and meeting notes have good products. The limits show at the second workflow, which needs a second tool, and at the approval step, where most tools stop at the edge of their own product. A roadmap engagement names the tools that fit and the gaps between them.
Hire a large consultancy
Built for enterprise scale: many functions, a large budget, and a program office. The model is people billed by the hour, typically $400–$1,000+ per hour, and a strategy engagement runs $150K–$750K. For a mid-market company with one or two processes to fix, that is a lot of structure for a small outcome, and the common failure is a program that ends at the pilot with the building still to do.
Hire a boutique or a freelancer
A trusted individual on a contained task can be the fastest route of all, and the new wave of experienced, modestly priced consultants is real. The risks are key-person dependence and the absence of a record: when the person leaves, so does the knowledge of what the agent does and why. If you go this route, insist on the twenty checks in the pilot-to-production checklist, especially the approval map and the record.
Work with KOI
KOI runs every engagement on its own platform, in which governed agents do the analysis and the build and one senior consultant directs them and signs off everything you see. The first agent is live in four to eight weeks, fees start at $50K per use case and are fixed against a metric agreed before work starts, and governance is built into every deployment. It is the right route when you have a named process, a measurable outcome, and a need for the controls a regulated or multi-site business requires, without an enterprise budget. It is the wrong route for a task a prompt would finish, and KOI will tell you so and charge nothing.
How to choose
- 1.Name the process and the metric. If you cannot, start with the readiness assessment, not with any of the five.
- 2.If a mature tool covers the whole workflow, including approvals, buy it.
- 3.If the process is core to your product and you have engineers with capacity, build it.
- 4.If you need governance, integration with several systems, and a fixed price, and you do not have an enterprise budget, that is KOI's work.
- 5.Whatever you choose, get a working prototype before you sign. KOI's is free and arrives within two business days.
