Apps and APIs with AI sales assistants: how RV3 ships AI in production

At RV3, AI isn't a slide deck headline. It's a tool we use to sell more, sell better, and sell 24/7.

Our core product on this line is building apps and APIs powered by AI sales assistants for our clients — qualified chatbots, conversational agents integrated into the website, automations that pick up leads from the first visit and walk them all the way to payment.

To ship those products fast and well, we use AI ourselves — Claude and Mistral — at the heart of our development pipeline.

What we build for our clients

AI sales assistants embedded in the site

A visitor lands on your site. Instead of a contact form that ends up in an unanswered inbox, they meet a conversational assistant that:

Understands the question in the visitor's language (EN / FR / ES by default).
Qualifies the need in a few natural exchanges — product, budget, urgency.
Handles common objections with real information from your catalog.
Books a slot or hands off to WhatsApp / a human when the lead deserves it.
Logs the conversation in your CRM with a quality score.

The result: more leads converted, less friction, and a sales rep who only handles the high-value conversations.

Custom AI-powered APIs

Beyond chat, we build bespoke APIs:

Automatic quote generation from a client brief.
Inbound email classification and routing (support, sales, partnership).
Lead scoring based on behavioral and conversational signals.
Dynamic product recommendations based on visitor context.
Automatic call summaries for the CRM.

These APIs plug into your existing stack — website, CRM, ERP, WhatsApp Business — without breaking what already works.

Why Mistral and Claude

Mistral for European data

European model, hosted in Europe, with clear GDPR guarantees. It's our default when:

The conversations carry sensitive client data.
The client operates in France or in Europe and doesn't want data to leave the EU.
Multilingual workflows EN / FR / ES are core to the project — Mistral excels there natively.

Claude for complex reasoning

Claude (Anthropic) is our pick for:

Complex sales assistants that follow a multi-step qualification strategy.
Document processing (briefs, contracts, long product descriptions).
Decision-making agents — re-engage a lead, escalate to a human, suggest a discount.

We often combine the two: Mistral on the front line for speed and cost, Claude on the second line for cases that need real reasoning.

How we develop these products — fast and clean

Building a sales assistant that speaks your brand voice, knows your catalog, and integrates with your CRM is several weeks of work. Except we use Claude in pair-programming across the entire pipeline:

TypeScript code generation for API integrations from a spec.
Structured system prompts for the agent — brand voice, guardrails, human fallback.
Automatic review of every pull request: security, error handling, type quality.
Documentation generated from the code and kept up to date automatically.

The result: an assistant in production within 4 to 8 weeks instead of 4 to 6 months on traditional dev — without compromising quality or security.

What we don't do

To be clear:

We don't ship a generic ChatGPT-wrapped assistant with your logo on top. Every agent is trained on your brand, your catalog, your typical objections.
We don't replace your sales team. The agent qualifies and clears noise; the human closes complex deals.
Your data never trains a public model. We use APIs with zero data retention and controlled hosting.
The agent never lies. If a question is outside its scope, it says so and hands off.

When this is a fit

If your activity has at least one of these signals:

You receive more inquiries than your sales team can handle.
Your contact forms have a low completion rate.
You operate in multiple languages and support quality varies by language.
You want a sales channel active 24/7 without hiring more people.
You manage a rich product catalog that visitors struggle to navigate alone.

…then an AI sales assistant could transform your conversion. We assess fit for free.

What's next

In the coming weeks we'll publish:

Three client case studies of sales assistants we shipped (legal chatbot, real-estate qualification, e-commerce pre-sales support).
How we connect Claude to WhatsApp Business so a client can converse with your brand in their preferred channel.
Security, GDPR and zero data retention — the checklist we apply on every AI project.
