01// why this exists
A trained agent that knows your business — working 24/7 with humans in the loop.
We build AI agents the way real software gets built: scoped to one job, trained on your SOPs, wired to the tools you already use, with an eval harness that proves it works. Cloud-hosted by default. Hard monthly spend cap. Approval queue for anything that touches money or customers. You get a dashboard you can actually read — and an agent that gets better, not flakier.

02// how it works
The architecture, end to end.
No black boxes. Here's the actual shape of the system you get — with the guardrails, eval loops, and human approvals where they belong.
AI Agent architecture
Signal in → grounded reasoning → tool use → human-approved action.

Real use cases we ship.

Inbound request → trained on your pricing → drafts quote → you approve → sends.
- 02
Customer follow-up
Day-3, day-7, day-30 nurture sequences personalized to each conversation.

Invoice + expense categorization
Auto-codes and posts to QuickBooks/Xero. Flags anything weird for human review.
- 04
Scheduling & coordination
Calendar-aware booking, rescheduling, and confirmation across your team and clients.

Document review & extraction
Contracts, intake forms, vendor docs — pulls fields, flags risk, files cleanly.
- 06
Internal Q&A on your SOPs
Slack / Teams bot trained on your playbooks. Cites source. Says "I don’t know" honestly.
04// what you walk away with
The outcome, not just the output.
- 01A custom agent trained on YOUR business processes — not a generic assistant
- 02Live dashboard showing every action, cost, and decision the agent makes
- 03Eval harness that catches regressions before they hit production
- 04Human-in-the-loop guardrails on financial + customer-facing actions
- 05Monthly cost cap so you never get a surprise OpenAI bill
- 06Documented playbook so your team can update prompts and tools without us

Every flagship engagement ships with a control panel — live activity, eval pass rate, spend cap, and an approval queue you can act on from your phone.

Forecast — actual capped in prod
Recommended monthly cap: $450 — we set this hard ceiling in production. Agent auto-pauses when hit, with a Slack alert at 80%. You raise it only if you want to.
80% alertEstimate uses average token costs and observed agent behavior in similar deployments. Final budget is set with you during scoping and enforced with a hard monthly cap. BYOK supported — pay your provider directly, we don't mark up tokens.
05// methodology
How the engagement actually runs.
Concrete phases, concrete artifacts. You always know where we are and what comes next.
- Week 1
Discovery + agent design
Process mapping with your team. Identify the workflows the agent will own. Design the tool library, knowledge base structure, and eval criteria. Lock the scope.
Process mapTool specEval rubricCost forecast - Week 2
Build — runtime + tools
Stand up the agent runtime, wire the tool library to your stack, ingest your SOPs into the knowledge base. First end-to-end run on test data.
Agent runtime deployedTool libraryKnowledge baseFirst eval run - Week 3
Evals + dashboard
Build out the eval harness with real cases from your business. Stand up the operations dashboard. Wire human-in-the-loop approval flows on high-risk actions.
Eval harnessOps dashboardApproval flowsCost monitoring - Week 4
Pilot + handoff
Soft-launch with one team, monitor evals and dashboard, tune prompts. Documented playbook + 60-minute training session + 30 days Slack support.

06// scope
Concrete artifacts you keep — and what we leave out.
Working code, written docs, dashboards your team owns. We also list what this engagement deliberately does not cover, so scope is honest before you sign.
// deliverables
- Agent runtime (LangGraph or equivalent) deployed to your cloud or ours
- Tool/function library wired to your stack — CRM, calendar, billing, docs, email
- Knowledge base built from your SOPs, processes, and reference docs
- Eval harness with 30–80 test cases derived from your real workflows
- Operations dashboard — live activity, cost meter, eval scores, error log
- Human-in-the-loop approval flows for high-stakes actions
- Monthly cost cap + alerting
- Operations playbook (how to add tools, update prompts, review evals)
- 30 days post-launch Slack support + tuning
// not included
- Ongoing agent operations (use Agent Operations Retainer)
- Building net-new business processes (we automate what exists)
- Replacing licensed software (we wire to existing tools)
- On-premise installs (cloud-hosted by default; VPC available as enterprise add-on)
// add-ons

How we reduce risk
Async-first, weekly demos, no surprises
You see exactly what shipped each week. No status meetings to attend, no reports to chase.
Code is yours from day 1 — no lock-in
Your repo, your infra, your accounts. We work in your stack. You can take the work in-house at any time.
07// questions
Honest answers.
01How is this different from buying ChatGPT Enterprise?
ChatGPT is a general assistant. This is a specialist trained on your processes, wired to your tools, with measurable outputs. ChatGPT can answer questions about your business; this one runs parts of it.
02What if the agent makes a mistake on something important?
Every action that touches money, customers, or external systems goes through a human-in-the-loop approval flow by default. The agent drafts; a human approves. Over time, as eval scores prove out, you can lower the bar for low-risk actions.
03Where does my data live?
Your cloud (AWS, GCP, Vercel, Supabase) or our managed environment — your call. We use your LLM API keys (BYOK), so your prompts and outputs never touch our infrastructure. Enterprise VPC deployment available.
04How much does it cost to RUN per month after launch?
Depends entirely on volume — typical small-business agents run $50–$400/month in LLM costs. We give you a cost forecast in week 1 and put a monthly cap in place so you never get surprised.
05Can I add new tools or processes later?
Yes — that's what the Operations Retainer is for. Or your team can do it themselves; the operations playbook covers it.
06Do you do desktop installs?
No, by default. Desktop installs mean you can't push fixes, security becomes harder, and support gets messy. Cloud-hosted with SSO is the standard. If you need on-prem for compliance reasons, that's an enterprise add-on.
