What we build with LLMs
Custom LLM applications
Assistants, copilots and internal tools built around your workflows, not a generic chat window.
LLM integration
Add GPT, Claude or Gemini to your existing product through secure, well-tested APIs.
Open-source and private models
Deploy Llama and other open models on your own cloud when data must stay in-house.
Fine-tuning and evaluation
Tune models on your examples and measure accuracy with test sets before and after launch.
Guardrails and safety
Input and output filtering, PII masking, grounding checks and human review where needed.
Cost and latency optimisation
Model routing, caching and prompt design that keep responses fast and bills predictable.
How we approach LLM development
Choosing the right model
There is no single best model. We compare OpenAI, Claude, Gemini and open-source options on your real tasks for accuracy, speed, cost and data handling, and design the app so the model can be swapped later without a rewrite.
Grounded in your data
Most business value comes from connecting the model to your documents, databases and tools. We use retrieval (RAG), function calling and agents so answers come from your information and actions happen in your systems.
Built for production, not demos
We add evaluation test sets, logging, monitoring, rate limits, fallbacks and cost alerts from day one, so the app keeps working well after launch and you can see exactly what it is doing.
Security and compliance
Data minimisation, encryption, access control and providers configured not to train on your data. For healthcare we build to HIPAA requirements with BAAs in place for any service that touches PHI.
Remote, but close to Sao Paulo
Time-zone overlap
Brazil is eight and a half hours behind India. We run flexible late shifts for a live daily stand-up in your morning, and the rest of the work moves forward while you sleep.
Brazil's General Data Protection Law (LGPD)
We design to the LGPD: a legal basis for each use of data, data-subject rights, security controls and data hosted in Brazilian cloud regions when required. We sign NDAs before work starts.
Billing
Invoices in Brazilian reais (BRL) or US dollars. Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for Sao Paulo's key sectors
Sao Paulo startups and businesses work with us on fintech, marketplaces and AI automation, designed to the LGPD.
Agribusiness
Large-scale farms adopt precision agriculture and logistics tools. AI here usually means faster reporting, fewer manual steps and better customer replies.
Fintech and banking
Digital banks and Pix reshaped how Brazilians pay. We start with one costly process and automate it end to end.
Retail and e-commerce
Mobile shoppers expect instalments and fast checkout. We build AI agents, assistants and automation around these workflows.
Mining and energy
Resource companies digitise operations and safety. AI here usually means faster reporting, fewer manual steps and better customer replies.
