Custom-built agents · not no-code prompts

AI agents that actually work. In production.

Tool-using agents on Claude and GPT — with RAG, evals, guardrails, observability, and human-in-the-loop where it matters. Built by a Vancouver, BC team shipping production AI, not demos. Discovery from $3,500, builds from $9,000.

What you walk away with

A production agent — not a Notebook your CTO has to keep alive on weekends.

Workflows the team stops doing

Customer support triage, order ops, lead qualification, internal Q&A, content drafting — wired to the same tools your team uses today.

Evals-driven quality

Every agent ships with a written eval suite. Quality is a number we track per release — not vibes after a demo.

Guardrails by default

Tool-allow-listing, input/output filters, prompt-injection defense, audit logs. Production AI that survives an enterprise review.

Tools wired in correctly

Stripe, Shopify, HubSpot, Slack, Postgres, your APIs. Real tool use, not pretend — with retries and idempotency keys.

Human-in-the-loop where it matters

Refunds over $500, customer escalations, anything irreversible — gated for human approval, with a Slack-style review UI.

Observability you trust

Token usage, latency, cost-per-task, success rate, error tags. Dashboards that answer 'is the agent good today?' in one glance.

Where agents pay rent

Three workflow patterns we ship most often.

Customer-facing, internal ops, and revenue-side. Each one has the same anatomy — only the tools and rubrics change.

Customer support

Tier-1 deflection without trashing the brand.

  • Triages and answers Tier-1 tickets (RAG over your docs)
  • Issues refunds, status updates, order lookups
  • Escalates to humans with full context
  • iOS / Android / web / Slack / email surfaces
  • Evals against your past resolved tickets

Best for: DTC, SaaS, marketplaces with high Tier-1 ticket volume and clear escalation rules.

Internal ops

The work your team does between Slack messages.

  • Order review, inventory rebalancing, refund triage
  • Cross-system data reconciliation
  • PR/change-request reviewers for low-risk merges
  • Internal Q&A over wikis + tickets + Slack history
  • Slack-native interface with human-in-loop gates

Best for: Ops-heavy companies (retail, fintech, healthcare-ops, logistics) drowning in repetitive internal work.

Sales + marketing

The pipeline your reps wish they had time for.

  • Lead enrichment + qualification at scale
  • Personalized outbound (without sounding like AI)
  • RFP / discovery-call summarization
  • CRM hygiene — dedupe, enrich, route
  • Daily-stand-up briefings for revenue leaders

Best for: B2B SaaS and services teams with named-account motions and tight rep capacity.

Don't see your workflow? The discovery audit ($3,500) maps any candidate workflow against feasibility, eval design, and tool wiring before any code gets written.

Anatomy of an agent

Five things every production agent needs

The difference between a Friday-night ChatGPT demo and an agent your CFO is comfortable putting in front of customers.

01

Trigger

An event fires the agent: a new ticket, a webhook, a cron, a Slack message, an API call. The agent's scope is defined by the trigger.

02

Reasoning loop

The model plans, picks tools, executes them, observes results, and repeats until the task is done — bounded by step + token + cost limits.

03

Tool calls

Real APIs: Stripe, Shopify, your Postgres, your internal endpoints. Typed schemas, retries, idempotency keys, and audit logs on every call.

04

Guardrails + human-in-loop

Allow-list of tools, output filters, prompt-injection defenses. Irreversible actions gate for human approval via Slack or your admin UI.

05

Evals

Every release runs against a versioned eval suite. Quality is a metric, not a hunch. Regressions block deploys, full stop.

What's included

Eight surfaces, one production system

Everything we ship on a typical Build — and what the Care retainer keeps alive after launch.

Tool-using agents on Claude or GPT

Model-agnostic prompt programs, structured outputs, function calling, multi-step reasoning — picked per task on cost × quality.

Retrieval (RAG)

Hybrid retrieval over your docs, tickets, code, or product catalog. Indexed in pgvector, Pinecone, or Turbopuffer — picked for your latency + cost.

Tool wiring

Stripe, Shopify, HubSpot, Postgres, your APIs. Typed schemas, retries, audit logs. Real production plumbing.

Evals + regression suites

Golden datasets, LLM-as-judge where useful, deterministic asserts elsewhere. Quality tracked over releases.

Guardrails + safety

Tool-allow-list, output filters, prompt-injection defenses, jailbreak resistance. Auditable.

Human-in-the-loop

Slack-native approval UI for irreversible actions. Reviewers see context + reasoning + tool calls.

Orchestration + durability

Inngest, Temporal, or Mastra for long-running flows. Crash-safe steps, retries, observability across runs.

Observability + cost

LangSmith / Helicone / OpenTelemetry. Token spend, latency, success rate, error tags — all on the dashboard.

How we ship agents that don't embarrass you

Evals-first. Shadow before cutover. Maintenance built in.

01
Week 1-2

Discover

Workflow audit, candidate task selection, eval rubric design, scoping doc. The discovery audit ($3,500) ends with a go / no-go recommendation.

02
Week 2-8

Eval-first build

Golden dataset before code. Prompt program, tool wiring, retrieval, guardrails — each shipped against the eval suite, not against vibes.

03
Week 8-10

Shadow + canary

Run alongside the human workflow before fully replacing it. Compare outcomes, tune evals, then canary, then full rollout with auto-rollback.

04
Ongoing

Maintain

Monthly eval re-runs as models change, drift detection, new tools as the workflow expands. Optional Care retainer keeps it sharp.

Why custom-built

No-code agents vs. custom-built agents

No-code is amazing for prototyping. For anything in front of customers or money, the gap shows up fast.
