The agent does the whole job.
The harness proves it's correct.
We build agent systems that take a real assignment, research it across dozens of sources, compute the answer, and assemble the deliverable in your exact format — then verify every value against a primary source before anything ships. Work that takes an expert days is done in minutes, and indistinguishable from their best.
What we build
Not a chatbot bolted onto a workflow. The workflow, rebuilt as a machine.
We take a knowledge-work process that people insist can't be automated — judgment, messy sources, formats that must be exact — and turn it into a deterministic system with verification wired through every stage.
The reference build is TitleDesk Agent — landman title research software that reads county records on the landman’s own computer, builds a source-linked runsheet, and computes mineral ownership in exact fractions. Shipped, not a demo.
Read the assignment, plan the attack
The system parses a real work order and builds a plan — every data point labelled with where it comes from and where it lands in the deliverable.
Extract facts across 20+ sources
Hundreds of files and millions of words, online and local, scanned for the exact values each field needs — pulled into a workspace with their locators intact.
Reconcile and calculate, exactly
Domain math runs on exact arithmetic — no floating-point drift, no silent rounding. Conflicts surface as decisions, never as guesses.
Build the deliverable in your format
Every document, sheet and folder produced to your specification — the right file types, the right structure, the way your reviewers expect to receive it.
Prove each value before it ships
Every field runs the accuracy gates below. Nothing is marked done until confidence clears the bar and each answer is backed by evidence.
The correctness pipeline
Raw sources in. A signed, verified deliverable out. Every value checked on the way.
The interesting engineering isn't the model — it's the gauntlet the output has to survive. Data flows left to right and cannot exit a stage until it passes.
Every required field has an accepted source, or the run stops instead of guessing.
Extracted values match the primary record — not a plausible lookalike sitting next to it.
Each value carries a locator back to exactly where it was found, so any answer can be traced.
Sums, splits and fractions reconcile exactly, with no rounding papered over a shortfall.
The deliverable's files, names and structure match your specification precisely.
Overall confidence is measured, and any single gate failure fails the whole run.
Five-sigma isn't a slogan. Confidence is computed from the gates and the evidence behind each field — and because one failure forces the entire run to fail, a green result means green everywhere, not a good average hiding a bad cell.
How we make it trustworthy
Engineered for correctness, not demos.
Anyone can wire an API to a prompt. Shipping something a professional will stake their name on is a different discipline. This is where we spend our time.
Deterministic executors
The same input yields the same artifact, byte for byte. Runs are reproducible and auditable — no “it worked last time.”
Source-provenance gates
No value ships without a locator back to a primary source. Invented citations and unsupported fields are rejected before release.
Prompt-injection containment
Untrusted document text is treated as data, never instructions. Tools run least-privilege, so a poisoned file can't take the wheel.
We test the tests
Property-based suites plus mutation sweeps: we inject faults on purpose and prove the checks catch them. Green tests earn their green.
Signed, reproducible packages
Deliverables are Ed25519-signed and content-hashed. Tampering is detected on reopen; a failed build never overwrites a good one.
Exact arithmetic
Fractions stay fractions. Quantities that must sum to one sum to one — not 0.999 — through the whole pipeline.
Adversarial verification
Every claimed answer is attacked by independent checks before it's accepted. Confidence is measured, not asserted.
Offline-first & cross-platform
Runs on your machines — Windows, macOS, Linux. Your data and credentials stay with you; nothing is hosted that doesn't have to be.
How an engagement runs
We learn the job from work that's already proven right.
No hand-wavy “AI transformation.” We anchor to ground truth, encode the real procedure, and don't call it done until the output matches — value for value.
Discovery
We map the process end to end — the judgment calls, the sources it draws on, and the exact format the output has to land in.
Ground truth
We take completed, already-reviewed work as the source of truth to measure against. Accuracy needs something real to be accurate to.
Shadow a real run
The system watches the work done once, the manual way, and records every step — where each value comes from and where it belongs.
Build the harness
That becomes a fixed, repeatable workflow with the accuracy gates wired through every stage.
Prove it
We run it against ground truth until the output is indistinguishable from your best expert's — then we run it again to be sure.
Handoff
It's yours: on your machines, your data, your credentials, with runbooks and no hosted secrets.
Principles
What we won't compromise.
Evidence over eloquence
A confident sentence isn't a fact. Every answer is backed by a source, or it doesn't ship.
Determinism over demos
A flashy one-off is worthless if it can't be reproduced. We build for the thousandth run, not the first.
Refuse over guess
When the evidence isn't there, the system stops and says so — it never invents a value to look finished.
You own it
Customer-owned, on your infrastructure. No lock-in, no hostage data, no black box you can't audit.
Engagements
Four ways we come in.
Custom systems
We design and build the whole harness around your process — intake to verified, packaged output — and hand it over as yours.
Stalled agents
An agent build that half-works, hallucinates, or can't be trusted in production. We find why and make it correct.
Correctness & security
An independent review of an existing agent system — accuracy, provenance, injection surface, failure modes — with findings you can act on.
Harness & runbooks
The operating layer your agents run on — sandboxing, tooling, smoke tests, handoff — set up cleanly with no hosted secrets.
Start a build
Bring us the workflow everyone says can't be automated.
Tell us the process, the sources, and the format it has to land in. We'll tell you exactly how we'd make it correct — and prove it.
Every engagement is scoped and led by Spencer Teague — Founder & Lead Engineer. Not routed through a generic agency bench.
Speed, with proof.
The messenger's speed, an engineer's discipline. We build the systems that carry expert work at machine speed — and the proof that every answer arrived intact.
