Galicia Seguros — predictive modeling and NLP across life, home, and auto.

Four years embedded in one of Argentina's largest insurance providers, building the analytics behind cross-sell, retention, and digital re-marketing for the bank's customer base.

01 · Context

A bank-owned insurer with millions of customers and rising acquisition costs.

Galicia Seguros operates life, home, and auto insurance lines across the existing customer base of one of Argentina's largest retail banks. The marketing organization had two compounding problems: outbound call campaigns were expensive and converting below target, and digital spend was being optimized on click metrics that didn't translate into policy purchases.

In parallel, the bank's own product team was marketing loans and cross-sell offers to customers without proper segmentation — sending the same offer to high-propensity buyers and unlikely converters alike. The cost of contact was constant; the yield wasn't.

02 · Scope of work

Three model families. One operating principle.

Every contact with a customer is a cost. Every model exists to answer one question — is this contact worth making?

Propensity

Per product line (life, home, auto) and per banking product (loans, cross-sell). Predict conversion probability in the next campaign window.

Segmentation & churn

RFM and unsupervised clustering on transactional behavior. Identify retention risk 60–90 days before cancellation.

NLP re-marketing

Conversational flows replacing call-center contact for repetitive inquiries — policy status, claims, premium calculations.

03 · Stack

Boring stack, aggressive iteration.

No exotic tooling. The win came from disciplined experimentation, A/B holdouts measuring incremental lift, and tight collaboration with the marketing team.

04 · Outcome

Measurable lift in sales. Material reduction in call-center costs.

The work delivered double-digit improvements in conversion across campaigns and a substantial drop in cost-per-contact, measured against A/B holdouts retrained quarterly. Models remained in production with documented assumptions so the team could maintain them after the engagement.
