01
Classification
Emails, leads, tickets, transactions — sorted into the right bucket with a label, a confidence score, and a reason. Routed automatically.
AI Workflows.
Real automation. Not chatbots.
We embed LLMs into the actual work your team does — classifying leads, extracting from documents, drafting replies, routing tickets. Structured outputs, validated. Wired to your existing tools. Running quietly while you do the work that needs you.

The thesis
Most AI demos are toys.
Most AI demos are toys.
Real AI workflows are load-bearing.
The flashy stuff — image generation, hallucinatory chatbots, "agents" that do laundry — gets the headlines. The work that actually pays: a model that classifies a thousand leads a day, extracts the right fields from invoices, drafts the reply, routes the ticket. Boring. Quiet. Saves your team a Tuesday every week. We build that kind. Wired with structured outputs, validated, with a human-in-the-loop where it matters.
~$0.005 per item processed A modern model can read, classify, and extract from a 5-page document for half a cent. Manual costs $4–$12.
95%+ accuracy floor With structured outputs and validation, modern LLMs hit human-grade accuracy on most well-scoped tasks.
90 days pilot to production Most workflows go from "interesting demo" to "actually running" in one quarter — including evals and rollback.
What we build
Six shapes of useful AI.
Most production LLM work falls into one of these patterns. We've shipped variants of all six. Combine them and you've got an autonomous back office.
02
Extraction
PDFs, emails, contracts, forms — turned into typed JSON. Validated against your schema, retried on bad outputs, sent to the right system.
03
Summarization
Calls, threads, meeting transcripts, doc trees — collapsed to the parts that matter. With action items, decisions, and follow-ups separated out.
04
Generation
First-draft replies, follow-up sequences, content briefs, policy docs — produced in your voice from your data. Always with a human-in-the-loop checkpoint.
05
Search & RAG
Your wiki, your contracts, your support history — turned into something your team (or your customers) can ask questions of. Cited answers, not vibes.
06
Agents & tools
Multi-step workflows that actually do things — call your APIs, read your DB, write to your CRM. Sandboxed, observable, with circuit breakers.
The trace
Every run is observable.
One thing that goes wrong with most AI projects: nobody can see what the model is doing. We log every step — input, reasoning, tool calls, output, validation result. So when something drifts, you find it before your customers do.

How it works
Map. Pilot. Productionize. Watch.
Map the work.
A short interview with the people doing the task. We watch one or two real cases, write the spec, define what "right" looks like. Hard parts surface here, not later.
Pilot offline.
We build a labeled eval set first. Then a prompt. Then we run it. Accuracy, cost, latency — measured before anything touches production. If it can't beat the bar, it doesn't ship.
Productionize.
Queue, retry, validation, observability, human-in-the-loop, rollback. The boring parts that make the difference between a demo and a workflow that survives a Tuesday with bad data.
Watch & iterate.
Models drift. Inputs change. Edge cases pile up. We hold a monthly review against the eval set, swap models when better ones land, and grow the test suite as the workflow earns more autonomy.
Better with the full system.
AI workflows live downstream of everything else. They classify the leads marketing brings in, summarize the calls sales takes, draft the replies support sends. When we run the whole stack, the model has the context it needs.
Attract Google Ads Score every form fill from your campaigns. Stop your team from chasing the bottom 80% of leads. Convert Web Design Smart forms that classify, route, and pre-fill from prior context. Less friction, better data. Automate Custom Software Workflows live inside the tools we build. Same data layer, same observability, same deploy.
Real reviews. Real clients.
These aren't cherry-picked. Every one of these came from a client who paid us, worked with us, and chose to say this publicly.
