— What we build

Six chatbots, one delivery team.

From L1 support deflection to agentic operators that drive your tools end-to-end, we ship the chatbot pattern that fits the job — never the other way round.

Agentic workflows that ,
take actionh , not just answer.

Multi-step agents that plan, call your tools (CRM, ERP, ticketing, payments), self-correct on failure, and close the loop — with human-in-the-loop guardrails and full traceability.

Capabilities & stack

Boring tech that
ships on time.

We pick the stack for the job, not the demo. Closed-source where ROI is clear, OSS where you need control. Always evaluated, never vendor-locked.

How we pick

01

Eval before adoption

Every model + retriever runs through our task-specific eval harness.

02

Cost & latency budget

P95 latency and per-conversation cost agreed upfront.

03

Swap-ready abstraction

Provider-agnostic layer — switch LLMs without a rewrite.

04

Guardrails by default

Prompt-injection defense, PII redaction, output filters.

FAQ

The questions
everyone asks before kickoff.

Still curious? Ask Zia in the hero chat — or book a 30-min strategy call with a senior engineer.

How long does a chatbot project take, end to end?

A focused L1-support bot ships in 6–8 weeks; a RAG knowledge bot with custom integrations is typically 8–10 weeks; an agentic workflow with multiple tools and guardrails is 10–14 weeks. We share a fixed timeline + milestones after the discovery sprint.

Both — we benchmark on your task in week one. Closed-source where ROI and latency win; open-weights (Llama, Mistral, Qwen) where you need on-prem, lower per-call cost or fine-tuning. Provider-agnostic abstractions keep you swap-ready either way.

Three layers: retrieval-grounding with citations, structured outputs validated against schemas, and a continuously-run eval harness with task-specific datasets you sign off on. Production traces are sampled and human-graded weekly.

Yes — that’s the default. We integrate with your CRM, helpdesk, ERP, data warehouse and custom APIs through a tool layer with auth, rate limits and audit logging. Read-only on day one; write-actions gated behind explicit human approval until guardrails are proven.

We’re SOC 2 Type II and ISO 27001:2022 certified, HIPAA-ready, NDA-friendly by default. Standard build includes PII redaction, prompt-injection defense, output filtering, role-based access and audit transcripts you can export.

We agree 2–4 outcome metrics with you before kickoff — typically deflection rate, CSAT, resolution time, cost per conversation, conversion lift. Dashboards are live from week two, and renewals are tied to hitting them.

Yes — we build channel-agnostic by default. The same conversation engine powers web embeds, WhatsApp Cloud API, voice via Twilio/Vonage, Slack and Teams. Channel-specific UX (quick replies, voice latency, file uploads) is handled per surface.

Project-based builds start around $45k for a focused scope. Dedicated squads range $28k–$65k/month depending on team size. Staff augmentation is per-engineer monthly. We share a transparent quote after a 30-min discovery call.
