A GenAI sales concierge on WhatsApp

Client Success

Chat. Choose. Drive. A Generative AI sales concierge on WhatsApp—turning the first mile of vehicle discovery into a conversation that actually converts.

To understand the fix, you have to feel the friction.

The Friction We Fixed

Across 130+ markets and multiple marques, buyers were bouncing between PDFs, slow pages, and busy reps just to compare trims or confirm a feature. Every time a browser tab changed or an email thread stalled, context evaporated and decision-making slowed. Sales teams repeated the same answers. Marketing couldn’t see where interest dropped off. Costs kept stacking up. The brief crystallized into one line: “Make exploration conversational, accurate, and instant—inside the app customers already use.”

Once the pain was named, the path became obvious—go where the customer already is.

The Move: Bring Sales to WhatsApp

Rather than bolting a bot onto a website, we embedded a governed, multilingual GenAI assistant inside WhatsApp Business. Now customers can:

  • Ask for trims, pricing, availability, or color options in natural language.
  • Receive images, brochure snippets, and spec comparisons inline—no downloads, no dead links.
  • Book test drives and progress toward purchase without jumping channels.
  • Stay in a single thread where the assistant remembers preferences and past questions like a seasoned sales rep.

Chat is the new showroom. Keep buyers in-thread and you keep their intent. But, a great idea still needs a repeatable mechanism.

How It Works

  1. Say hello on WhatsApp: “Show me the variants of the compact SUV.”
  2. Semantic match: The query is embedded and checked against a private vector store of geo-approved brochures and manuals.
  3. Persona prompt: The system assembles a sales-advisor persona to answer in the right tone, with only approved facts.
  4. LLM reply: A grounded, conversational response is generated—no hallucinations, no off-brand detours.
  5. Media delivery: Images, PDFs, and video hooks are resized and sent inline so users never leave the chat.
  6. Memory & continuity: Follow-ups don’t restart from zero; context persists, so the conversation flows naturally.
  7. Region-specific adaptation: Brochures/manuals are tagged by geography so responses always match local specs.

Under the hood is where trust, accuracy, and scale are engineered.

Under the Hood (Secure, Governed, Scalable)

  • Closed-loop RAG on AWS: Content is chunked, embedded (AWS Titan), and stored privately. Every answer traces back to approved source files.
  • Claude Sonnet 3.7 + persona prompting: The assistant behaves like a patient consultant—tuned per brand and per region.
  • Twilio + Prelio + WhatsApp Business API: Enterprise-grade messaging, role-based access, audit trails, and easy CRM hooks.
  • Future hooks baked in: Finance calculators, insurance quotes, claims initiation, and damage assessment via image/video plug in without re-architecting.
  • Enterprise-grade security & control: Role-based access and data governance ensure compliance at scale.

Engineering is only impressive if it moves the business needles.

Impact That Matters

  • 70% faster shortlisting — decisions happen in-chat instead of in-store.
  • 3x sales productivity — reps stop copy-pasting answers and focus on closing.
  • Cost per inquiry: ~$8–10 → < $1 — automated conversations slash support spend.
  • +8–12% projected conversion lift — continuity and confidence go hand in hand.
  • 20–30% of leads shifting to WhatsApp — an always-on, low-friction channel where buyers already live.
  • With an estimated 600,000+ annual leads globally, the scale impact is substantial.

Beyond a Bot: A Platform Pattern

What began as a discovery assistant is a blueprint for the entire ownership journey:

  • Purchase Pathways: Test drives, EMI calculators, accessory bundles—handled inside chat.
  • Immersive Next Steps: 360° views, walkaround videos, AR showrooms—all on the same conversational rail.
  • Personalized Nudges: Past interactions fuel timely, relevant offers without feeling like spam.
  • After-Sales Support: Service reminders, claims workflows, and AI-assisted damage assessment—users upload accident photos and the assistant geo-routes them to the right center, with future image/video analysis for validation

Platforms succeed when the partner behind them understands both vision and governance.

Why the Client Chose Persistent

  • GenAI in the wild: We deploy LLMs where customers already are—not just in lab demos.
  • Enterprise-grade governance: Private vector stores, AWS Bedrock controls, and compliance-first design.
  • Velocity with rigor: Rapid rollout without compromising brand voice or accuracy.
  • Scalable blueprint: Multi-brand, multi-region expansion via the same retrieval and prompt pipeline.
  • Roadmap fit: Financing, insurance, and post-sale journeys slot in as natural next steps.
