About J Labs
J Labs is the public brand of Jacarenda Labs LLC. We design and build the systems that run sales, finance, HR, recruitment and data inside operating companies, and we modernise the systems those companies already have. Fixed scope, fixed timeline, fixed price. Founded in 2024 by John McCoy.
Summary
J Labs is an AI integration and automation consultancy. The legal entity is Jacarenda Labs LLC, founded in 2024 by John McCoy and registered in Wyoming, USA; J Labs is the public brand. The company designs and builds the systems that handle sales pipelines, finance operations, HR processes, recruitment and data for operating companies of 50 to 5,000 people, and it modernises the systems those companies already run rather than insisting on rip-and-replace. Every engagement is fixed scope, fixed timeline and fixed price, with acceptance criteria agreed before work starts: a four-day Spec from €5,000 produces a vendor-neutral brief, and builds ship in an average of eight weeks with a 95% project ship rate. J Labs works remote-first across European and North American working hours. Alongside client work it operates a venture studio (Bump, Oran, Provn, ProprHome, Brief Me and Trustivo) and is an integration partner for the Blazing multi-cloud orchestration platform, deploying AI infrastructure for engineering teams at production scale.

Fit
This is for you if
You run a business with real systems and real operations. A CRM, a finance stack, an HR tool, an ERP, a database from another decade. Work that repeats every week and gets done by people who should be doing something else.
You want a fixed price and a system in production. Not a strategy deck, not a pilot that never leaves the lab. Scope, timeline and price written down, acceptance criteria agreed, weekly check-ins, your team in the room.
You can describe the problem in a paragraph. A specific workflow with a predictable trigger, an identifiable owner, data that already lives somewhere in your stack, and a budget holder who can say yes.
This is not for you if
You are a software company looking for a feature build. We work alongside operational systems, not inside your product or your engineering organisation. If the brief is "add AI to our app", we are not your team.
The brief is "we want AI somewhere in the business". We will tell you so on the discovery call and help you scope it down to something measurable. Vague briefs lead to vague results, and we would rather decline than disappoint.
You want to replace your team with ours. The work we automate is the work that should never have been done by a person. Judgement, relationships and strategy stay with your team. Always.
Founder
John McCoy founded Jacarenda Labs LLC in 2024 and runs it as founder and CEO. J Labs is the consultancy he built to do AI integration the way a serious technology partner would: a fixed price, a written scope, acceptance criteria agreed before any work starts, and a system in production at the end of it.
Alongside client work he operates the J Labs venture studio (Bump, Oran, Provn, ProprHome, Brief Me and Trustivo), which is where the consultancy's operating discipline comes from. Running live systems of your own changes how you build them for other people.
Operating principles
We ship before we slide-deck. The first deliverable on every engagement is something a real user can use. Strategy work, workshops and architecture documents come from a working system, not the other way round.
Embedded, not advisory. We sit inside the team that owns the outcome. Weekly working sessions, the same shared channel as your engineers, the same dashboards as your operators. No arms-length consulting deck once a fortnight.
Outcomes over hours. Every engagement has a fixed scope, a fixed price and acceptance criteria written down before any work starts. We do not bill by the hour. The system either does the thing or it doesn’t.
Receipts over decks. We would rather show you a live system we run than hand you a case study we wrote about one. Every principle here is one we have had to live with on a real engagement that went into production and stayed there.
