"Es simple: entendelo, Retenelo."

Retenelo detects at-risk customers and sends hyper-personalized AI messages — via email, WhatsApp, or in-app notification — when traditional retention methods have already failed.

Customer Retained

Traditional churn prevention has a blind spot.

Your existing tools weren't designed for the moment that matters most.

Generic emails get ignored.

One-size-fits-all re-engagement campaigns average under 2% response rates. Customers can spot a template the moment they open it.

Your team reacts too late.

By the time churn appears in your dashboard, the customer has already decided to leave. Reactive retention is expensive and rarely works.

Involuntary churn is silent.

Customers don't always tell you why they're leaving — but the signals are already out there. Most teams have no system to catch them.

Three steps. One goal: retention.

A fully automated pipeline from signal to personalized outreach.

Monitor

AWS Lambda crawlers scan breaking news, industry events, and external signals that are relevant to each at-risk customer — so every message is timed to the moment.

Personalize

The ML pipeline clusters the customer (KMeans), classifies the decline code, and picks the right incentive from verified inventory. Amazon Bedrock gets one job: how to say it.

Retain

The right message reaches the right customer at the right moment — via email, WhatsApp, or an in-app notification (like a Rappi pop-up) — before the decision to leave becomes final.

The technology behind every recovery.

A 7-step ML pipeline purpose-built for the Argentine market.

Machine Learning

KMeans Behavioral Clustering

Each failed payment triggers clustering.py — a trained KMeans model that assigns the customer to a behavioral profile. Tone, incentive, and timing adapt per cluster.

Payments

Decline Code Intelligence

Every failure hits decline_codes.json: Code 51 → retry after payday. Codes 41/43 → never retry, alternate channel. Payway's 15-attempt cap enforced automatically.

Smart Timing

Payday-Synced Timing

salary_calendar.py syncs every retry to Argentine payday windows: quincena, month-end, ANSES by DNI, aguinaldo spikes. We reach customers when they have money.

Trust & Safety

Code Owns the Offer. AI Owns the Voice.

Price, terms, and offer come from catalogo.json — determined by code, never by the LLM. Bedrock only writes the message. Retenelo cannot invent a price.

Compliance

Zero PII. Full Compliance.

No name, no address, no DNI — ever. The pipeline runs on usage history, age, and neighborhood zone only. Compliant with Ley 25.326 from day one.

What the customer actually receives.

Real examples for a book-subscription client. Notice what's missing: any mention of a payment problem.

Triggered by a news crawl — AWS Lambda

Triggered by reading history — KMeans cluster

Neither message mentions a failed payment — only a personal reason to stay. Titles, prices, and discounts come from verified inventory (catalogo.json); Bedrock only writes the words.
