The Problem

Generic AI tools create new problems
instead of solving old ones

No Business Context

ChatGPT doesn't know your products, your customers, your tone, or your processes. Generic output requires hours of editing to be usable.

You Can't Use Proprietary Data

Pasting sensitive business information into a public AI tool is a security and compliance risk. Your data should never leave your infrastructure.

Switching Between Tools

Copying content from your CRM into ChatGPT, copying output back, then formatting it manually defeats the purpose of using AI at all.

No Learning or Improvement

Generic tools don't learn from your feedback. Every interaction starts from scratch with no institutional knowledge of how you work.

FAQ

Common questions

Which LLM models do you use?

Primarily GPT-4o and Claude 3.5 Sonnet for most applications. We also work with Mistral, Llama 3, and open-source models when data privacy or cost requirements make them preferable.

Can you fine-tune a model on our data?

Yes, for use cases where RAG alone isn't sufficient - highly domain-specific language, proprietary terminology, or consistent output formatting. Fine-tuning adds cost but dramatically improves performance for the right applications.

How do you handle data security?

We deploy in your cloud account. Your data is encrypted at rest and in transit. No data is sent to model providers for training. We work to your specific compliance requirements - GDPR, HIPAA, SOC 2.

Do you sign NDAs before discussing our data?

Always. We sign mutual NDAs before any data, systems, or architecture discussions. Your intellectual property is protected from the first conversation.

How do we measure ROI?

We set baseline metrics before we build - time spent on the task, error rate, output quality. We measure against these at 30, 60, and 90 days post-launch. Most clients see payback within 3–6 months.
