Overview

Assistants and agents that use your own knowledge, safely.

LLMs are only useful when they answer with your data, follow your rules, and hand off cleanly when they shouldn’t answer at all. We build LLM apps with retrieval, guardrails, and evaluations from day one — because the difference between a demo and a product is exactly those three things.

It’s the right fit for teams turning a document library into a searchable assistant, product teams adding AI features, and ops teams that want agents to handle first-line work.

RAG + evalsGrounded and measured

Retrieval-augmented answers over your data, with automated evaluations we can show you.

What we deliver

Outcomes, not feature lists.

Every engagement ships against outcomes we agree up front.

01

RAG over your data

Answers grounded in your documents, cited to source.

02

Custom LLM apps

Chat, agents, and copilots for your product.

03

AI agents

Multi-step agents with tool use — behaviour bounded.

04

Guardrails

Refusals, safety filters, and PII handling by default.

05

Integrations

Slack, WhatsApp, your product, your APIs.

06

Evaluations

Automated evals for accuracy, safety, and cost.

FAQ

Common questions.

How do you handle hallucination?

Retrieval-augmented answers grounded in your content, a strict prompt, and refusals on out-of-scope questions.

Is our data used to train models?

No — not by default. We use provider APIs with training opt-out, or self-hosted open-weight models on your infra.

Which model should we use?

Depends on quality, latency, and cost. We route between models — and can self-host where needed.

What’s the cost per use?

Depends on model, prompt size, and traffic. We show a dashboard and tune for cost.

How long to build?

A grounded assistant is typically 4–8 weeks; agents take longer.
