AI
Your AI Evaluation Specialist builds test sets and marking rubrics for your chatbot or agent, red-teams it, and reports ship or hold with the numbers.
Automations that end re-keying
Zapier, Make or n8n connecting your CRM, forms, email and accounts, with AI steps that sort, extract and draft.
Assistants on your own content
Custom GPTs, Claude Projects, Gemini Gems or Copilot agents that answer from your policies, products and past work.
Chat and voice agents
Agents that answer, qualify and book, and hand over to a person when they should.
Reporting and analysis
Excel with Copilot, Power BI or Python, with every number checked against the source.
Tests before go-live
A test set that shows whether the AI gets it right before your customers see it, and alerts when it slips.
Our rule: business-grade AI only, never free or personal accounts.
A person signs off before anything goes live, and builds run on your accounts, so you own what's built.
