HIPAA-trained team, HL7/FHIR experience, and security practices that fit SOC 2-style questionnaires.
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.
How we work with San Francisco clients
Time-zone overlap
With flexible shifts we cover a live daily stand-up in Pacific time, and work continues overnight so new builds are ready for review each morning.
HIPAA and US state privacy laws
For healthcare we build to HIPAA requirements: role-based access, encryption, audit logs and HIPAA-eligible cloud hosting, with BAAs in place for vendors that touch PHI. For other products we follow US privacy laws such as CCPA, and we sign NDAs before any work starts.
Billing
Invoices in US dollars (USD). Typical senior rates are $25 to $49 (USD) per hour, or a fixed price for a defined scope.
Built for San Francisco's key sectors
Bay Area startups often need to ship an AI product quickly to raise or reach their next milestone. We act as an extension of the founding team: senior LLM, web and mobile engineers who can take a product from prototype to production and keep improving it.
SaaS and enterprise software
Fierce competition rewards fast product iteration and AI features. AI here usually means faster reporting, fewer manual steps and better customer replies.
Healthcare
Providers need HIPAA-aware portals, scheduling and claims automation. We start with one costly process and automate it end to end.
Financial services
Banks and fintechs modernise onboarding, fraud checks and payments. We build AI agents, assistants and automation around these workflows.
Retail and e-commerce
Direct-to-consumer brands live on conversion-focused stores and paid ads. AI here usually means faster reporting, fewer manual steps and better customer replies.
