Custom AI & Secure Chatbots.

Private copilots and customer-facing assistants built on your data — RAG systems hardened against prompt injection, jailbreaks, and data exfiltration. So you can actually ship them to production, not just demo them.

What we build — 01

Three shapes of custom AI.

Private copilots for your team, customer-facing assistants, and models trained on your data. Same underlying stack, different target users.

Shape · 01 · Internal

Private copilots

Slack-native, browser-extension, or embedded in your app. Answers from your SharePoint, Notion, Confluence, tickets, and code. Never trained on public data.

Shape · 02 · Customer

Support & sales bots

Web widget or WhatsApp. Handles tier-1 support, qualifies leads, escalates cleanly. Tuned for your brand voice, bounded to your domain.

Shape · 03 · Custom models

Fine-tunes & RAG

When a generic model isn't enough — fine-tuned classifiers, domain extraction, proprietary embedding spaces. With evals to prove they beat the baseline.

Hardening — 02

Security isn't a feature — it's the deliverable.

Every bot we ship goes through the same five-layer hardening pass. This is what separates a production system from a demo.

Layer · 01

Input guardrails

Every user message is screened against known prompt-injection patterns, jailbreak templates, and out-of-scope requests. Malicious inputs are rejected before they reach the model.

PROMPT INJECTION

Layer · 02

Policy enforcement

System prompts, tool permissions, and data-access policies are declared as code. The model can only see and do what policy allows — not what the prompt says.

SCOPE CONTROL

Layer · 03

Output filtering

PII, secrets, and internal codenames are stripped before responses leave the server. Retrieved context is redacted at the chunk level, not hoped-for at generation time.

DATA LEAK

Layer · 04

Full audit log

Every request, retrieval, tool call, and response is logged with user, timestamp, and trace ID. Searchable dashboards. Retention configurable for compliance.

TRACEABILITY

Layer · 05

Quarterly red teaming

We attack the bot every quarter with the latest jailbreaks, data-exfiltration patterns, and social-engineering attempts. You get the report. Zero critical findings in 12 months.

Questions — 05

What security-conscious teams ask first.

If your CISO has the question, we've had it from someone's CISO before. Happy to talk in detail.

Does my data ever train a third-party model?

No. We run on enterprise agreements with OpenAI and Anthropic that explicitly exclude training. Full DPA available. Data lives in your region.

Q·01

How do you handle prompt injection?

Multiple layers. Input classification, tool-permission whitelisting, sandboxed retrieval, and output filtering. Every bot is red-teamed before launch and every quarter after.

Q·02

Can we run it fully on-prem?

Yes. For regulated customers we deploy on your infra with open-weight models (Llama, Mistral) and self-hosted vector DBs. Performance gap is small, compliance story is airtight.

Q·03

Who owns the bot after launch?

You. Prompts, tools, and data pipelines are yours, in your git. We run it on MRR; you can take it in-house any time with full documentation.

Q·04

Related ways we ship AI.

Ship an AI your CISO trusts.

30-minute call. Bring your data story, compliance constraints, and the use case. We'll tell you if it's a fit, what the build looks like, and how the hardening works.
