What changes for you

Conversational
experiences that
drive real retention.

We focus on transactional success, not just generic message counts. Three commitments we make before writing any code.

  • 95%+ intent accuracy

    We structure complex multi-turn dialogs and intent mapping, ensuring the agent doesn't get lost in context drift or say "I don't understand." Golden sets, regression tests, and hallucination scoring run in CI before any prompt reaches production.

  • Predictable token costs

    By optimizing prompt caching, context window sizes, and routing between GPT-4o, GPT-4o-mini and fine-tuned smaller models by intent complexity, we keep cost-per-session predictable. Capped. Agreed before kickoff.

  • Deep legacy integration

    Your agent isn't a sandboxed widget. It connects natively to SAP, Salesforce, custom databases, and active SMS/Voice channels. Every prompt, every fine-tuned weight, every eval set - yours. No royalty. No lock-in.

Where most integrations break

The graveyard is full of naive chatbots.

Most enterprise chatbots fail because they treat conversations as static prompts. We design for absolute conversational resilience.

Who we work with

Built for the person on the hook.

Different leaders evaluate conversational AI on different metrics. We deliver exactly what you're measured on.

CTO · VP Engineering

My team built a chatbot wrapper but it's impossible to version and has no evals.

Deep conversation-state management, Dialogflow/LLM hybrids, CI regression testing on golden dialog sets.
  • Eval harness · CI/CD · cost instrumentation
  • Stack-neutral fallback built in
  • Full IP transfer · runbooks · on-call docs
COO · VP Operations

My ops team scales linearly with revenue. That can't continue.

Workflow agents that read your systems, decide, act and escalate - without replacing your stack.
  • Cycle time · throughput · $/transaction metrics
  • Human-in-loop for high-stakes steps
  • ROI dashboard before week one ends
VP Customer Support

We bought a chatbot. It still says "I don't understand" 40% of the time.

A GPT-powered agent trained on your ticket history - that resolves, not deflects.
  • Zendesk / Intercom / Freshdesk integration
  • 60–80% tier-1 resolution · CSAT-safe
  • Weekly KB-gap report
CIO · IT Director

Everyone's using ChatGPT at work. I can see none of it.

Enterprise-grade conversational AI inside your VPC - SSO, RBAC, audit logs, vendor risk docs.
  • Private VPC · no data leaves your boundary
  • SOC 2 controls · data redaction at edge
  • Vendor risk docs for your review board
CFO · Finance Ops

Our last AI project had no ROI. Just a slide deck.

Every engagement ships with a baseline, a target and a dashboard. ROI is a number, not a narrative.
  • AP / AR / invoice / reconciliation
  • NetSuite / QuickBooks / SAP connectors
  • Approval routing + audit-ready logs
VP Product

We need a conversational AI feature on the roadmap. We don't know where to start.

A 2-week discovery sprint: highest-ROI capability, working prototype, fixed-price plan.
  • Discovery sprint: $8k · cancelable · IP yours
  • Working prototype by end of week two
  • Fixed-price SOW or T&M your call
