Boutique Agency Front Desk: Vapi Agent 'Katherine' with Knowledge-Base Grounded Qualification

Problem:

BRAT, a boutique creative agency serving high-end fashion, real estate, tech, and product-design clients, was losing inbound project inquiries to unanswered calls — and its clientele expected a brand-caliber phone experience, not a generic bot.

Solution:

Built 'Katherine Kith' on Vapi running GPT-4o with an ElevenLabs voice, grounded in an attached Knowledge Base file covering BRAT's brand systems, strategic development, digital platform, and visual campaign services. Temperature 0.6 and a 300 max-token cap keep responses short and on-brand while the agent greets callers, qualifies project scope, and handles initial queries at ~1,750ms latency; a second assistant ('Riley') runs in the same workspace on the shared architecture.

Result:

BRAT callers now reach a brand-consistent agent that qualifies project scope on the first ring, with zero inbound inquiries lost to voicemail.
