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.
Do you build with closed models (GPT, Claude) or open-source?
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.
How do you handle hallucinations and accuracy?
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.
Can the bot use our internal tools and data?
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.
What about security, compliance and PII?
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.
How do you measure success?
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.
Will the bot work across web, WhatsApp, voice, Slack and Teams?
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.
What does it cost?
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.
