We build mobile, web & LLMs that don't spill.
Everything from first sketch to production
Four disciplines, one small team that has shipped at scale - mobile, web, LLMs & data, and the QA that holds it all together.
Good energy,
serious delivery.
Small enough to be fully hands-on, senior enough to have seen it all. We prototype like tinkerers and ship like operators.

How we work
From first sketch to models in production - and everything after launch.
*while downing gratuitous amounts of caffeine
LLMs that know your business
From your first document to a grounded, evaluated answer - the pipeline is the product, and we build all of it.
The RAG pipeline, end to end
RAG systems
Retrieval-augmented generation - answers grounded in your documents, with citations and no confabulation.
Enterprise knowledge bases
Search and chat over manuals, tickets, and wikis - institutional memory that stays current.
LLM-powered apps
Chatbots, copilots, and internal tools - scoped, tested, and shipped to the people who need them.
Data & ML pipelines
ETL, data engineering, and computer vision - data that flows from source to model, reliably.
Evals & guardrails
Evals, prompt-injection hardening, and monitoring - quality you can defend, not vibes.
Local LLM hosting
Open-weights models on your own infrastructure - your data never leaves the building.
