What we do

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.

In depth

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.

Working with us from Chicago

How we work with Chicago clients

Time-zone overlap

We overlap with Central Time mornings and offer flexible shifts for live stand-ups, with daily written updates in between.

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.

Sectors · Chicago

Built for Chicago's key sectors

Chicago's logistics, manufacturing and financial services companies come to us for software that connects to the systems they already run: TMS and ERP integrations, document automation, dashboards and AI assistants for operations teams.

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.
