Compare · J Labs vs an in-house hire
An in-house AI engineer is the right answer for some companies and the wrong first move for most. J Labs delivers a scoped, fixed-price system in an average of eight weeks and leaves your team running it. This page sets out when each option wins, without pretending the choice is obvious.
Summary
Hiring an in-house AI engineer and engaging J Labs solve different problems. A hire gives you permanent capacity: someone who learns your systems deeply and sits with your team every day. The cost is a senior salary plus the months it takes to recruit, and the risk that a single specialist is the wrong specialist for the work you actually have. J Labs sells the outcome instead of the capacity. Every engagement starts with a 20 or 45-minute discovery call and a one-page summary within 24 hours, then, where scope needs defining, a four-day Spec from €5,000 that produces a vendor-neutral brief you own outright. Builds are fixed scope, fixed timeline and fixed price, run on weekly 30-minute check-ins with your team in the room, and ship in an average of eight weeks; 95% of projects reach production. Engagements run from €5,000 to €200,000+. The people who will operate the system learn it as it is built, and a post-launch support window covers the first month of real usage. The honest split: J Labs when the work is a defined set of workflows on top of systems you already run; an in-house engineer when AI is your product or the work never stops. The two are not exclusive, and the Spec doubles as the job description if you recruit afterwards.
Side by side
| J Labs | Hiring an in-house AI engineer | |
|---|---|---|
| Time to first production system | An average of eight weeks from kick-off, with a four-day Spec first where scope needs defining. | Months to recruit and onboard before the first system is built. |
| Cost model | A fixed price per engagement, from €5,000 to €200,000+, with change orders for anything beyond scope. | A permanent senior salary plus recruitment cost, whether or not there is AI work that month. |
| Who owns the outcome | J Labs commits to acceptance criteria written into the proposal before the build starts. | The engineer owns delivery; the company carries the risk of a mis-hire. |
| Works with legacy systems | Yes. Connecting Salesforce, SAP, NetSuite or a bespoke CRM is treated as core engineering, not cleanup. | Depends on the individual; model expertise and legacy integration experience do not always arrive in one hire. |
| Scope discipline | Scope, timeline and price are written into the proposal; expansions become change orders you decide on. | Scope is whatever the roadmap says this quarter, which is flexible and easy to let drift. |
| Knowledge transfer | Your team is in the room from week one, with open staging, visible pull requests and documentation written as we go. | Knowledge lives with one person and leaves with them unless documentation is enforced. |
| What happens after launch | A post-launch support window, then a retainer, a managed service or nothing at all. Your choice. | Continuous ownership by the engineer, which is the main reason to hire one. |
| Best for | Companies of 50 to 5,000 people with defined workflows to automate on top of existing systems. | Companies where AI is the product, or where the AI work is continuous and there is an engineering team to join. |
The honest call
Choose J Labs when
You need a system in production this quarter. A hire takes months to recruit and onboard before anything ships. J Labs starts with a 20 or 45-minute call, ships in an average of eight weeks, and 95% of projects reach production.
The work is a defined set of workflows on systems you already run. Lead routing, invoice matching, document extraction, call summaries: rules-based work with a clear trigger and owner. That is project-shaped, and a fixed-price engagement fits it better than a permanent salary.
You are not yet sure what the hire would do. If you cannot write the job description, you cannot make the hire well. A four-day Spec from €5,000 produces a vendor-neutral brief you own outright, which doubles as the job description if you decide to recruit afterwards.
Choose hiring an in-house ai engineer when
AI is the product, not the plumbing. If your company sells software and the AI is what customers buy, the work never ends and the knowledge must sit inside your engineering organisation. J Labs does not build inside your product, and says so on the discovery call.
The work is continuous, not project-shaped. When there is a backlog of AI work that will keep a senior engineer busy every week of the year, permanent capacity costs less than a sequence of fixed-price engagements and builds deeper institutional knowledge.
You already have an engineering team for the hire to join. An AI engineer thrives inside a team with code review, deployment pipelines and someone to cover when they are away. A single hire landing alone, reporting into operations with nobody to review their work, is a much harder placement to make succeed.
