What we work with

Not tied to one provider, and never reselling you one.

The model, the cloud and the payment rail are chosen per job, on cost, on quality, and on where your data is allowed to sit. Every account and every licence is in your name, paid directly, with no markup from us.

Summary

What models, clouds and payment rails does J Labs work with?

J Labs, the public brand of Jacarenda Labs LLC, builds AI integration and automation systems that connect to the software a business already runs. We are not tied to one model provider: we build on Anthropic, OpenAI, Google Gemini, Llama and Perplexity, and the model is chosen per job on cost, quality and where the data is allowed to go. Systems run in the client’s own cloud account on Amazon Web Services, Microsoft Azure or Google Cloud, in the region their data is allowed to sit in, not on J Labs infrastructure. We connect to Microsoft 365 and Google Workspace rather than asking a team to move. For payments we have put Stripe, Revolut Business, Apple Pay and Google Pay into production. Where on-chain settlement genuinely beats a conventional rail we work with the XRP Ledger, Base, MoonPay, WalletConnect and MetaMask, and we say plainly when a conventional rail is the better answer. The client owns every account and every licence; nothing is resold with a markup.

Models we build on

We are not tied to one provider. The model is chosen per job on cost, quality and where the data is allowed to go, and it can be changed later without rebuilding the system around it.

Anthropic: Long documents, careful reasoning, and work where being wrong quietly is expensive.
OpenAI: General drafting, structured extraction and the widest tooling support.
Google Gemini: Long context and tight integration with Google Workspace data.
Llama: Open weights, for work that has to run on infrastructure you control.
Perplexity: Research with sources attached, where the citation matters as much as the answer.

Where it runs

Your system runs in your own cloud account, in the region your data is allowed to sit in. We do not host your business on our infrastructure.

Amazon Web Services: The default for most European clients already on it.
Microsoft Azure: Usually where a client is already committed to Microsoft identity and licensing.
Google Cloud: Strong where the data already lives in BigQuery or Workspace.

The tools your team already uses

Most of the value is in the software you already pay for. We connect to it rather than asking anyone to move.

Microsoft 365: Mail, documents, spreadsheets and meetings, including Copilot where it is licensed.
Google Workspace: The same, for teams on Gmail, Docs, Sheets and Meet.

How you get paid

Taking money is usually the part that decides whether a project ships. These are the rails we have put into production.

Stripe: Cards, subscriptions, VAT handling and invoicing for most European businesses.
Revolut Business: Multi-currency accounts and payouts where a client banks there.
Apple Pay: Through the processor, for the conversion lift on mobile checkout.
Google Pay: The same, on Android.

On-chain settlement

For clients who need it. This is a small part of what we do and we will say plainly when a conventional rail is the better answer, which it usually is.

XRP Ledger: Cross-border settlement where speed and cost beat the correspondent banking route.
Base: Low-cost transactions on an Ethereum layer 2.
MoonPay: On and off ramps between conventional currency and digital assets.
WalletConnect: The standard way a wallet connects to an application.
MetaMask: The wallet most users already have.

Something not on this list?

This is what we have put into production, not the limit of what we will work with. If your business already runs on something else, that is usually the right answer and we will connect to it.
