The Challenge
Mercado Libre, Inc., Latin America's leading e-commerce and fintech ecosystem, founded in 1999, operating in 18 countries with 84,000+ employees.
Initial situation: headcount freeze with 60-70 needed roles unfilled; 500+ contractors covering manual work. Multi-country complexity across Brazil, Argentina, Mexico, Colombia, and Chile. Manual discovery model meant months of interviews covering less than 1% of the workforce. Fragmented systems: SAP, ARIBA, PIC, CLM, Jira, BigQuery, Tableau, Apache, Bypass. Duplication overload: 600+ initiatives, many overlapping or misaligned.
Business objectives: liberate workforce capacity, shorten procurement/contract cycles, benchmark across countries, and ensure all initiatives delivered ROI greater than 150%.
Methodology
The Horizon Approach
Manual discovery model: months of interviews covering less than 1% of the workforce, requiring 100+ coordination hours per initiative. Cost of inaction: 12k-13k hours wasted annually, 76 additional hires required, vendor onboarding delays (30-45 days), and strategic initiatives slowed by duplication.
Horizon delivered full organizational coverage: 100% of key functions engaged vs. less than 1% sampling in consulting. Speed: 90× faster (4-day discovery vs. 11-20 weeks). Outcomes: ROI-validated initiatives, not static reports. Security fit: SOC 2, encryption, RBAC, anonymization, API integration with existing systems.
Full-scale discovery in days: AI agents interviewed 2,000 employees across Finance and related functions, covering 100% of targeted areas in 5 countries, versus the under-1% sample a traditional consulting engagement would reach. Transcripts fused with SAP/ARIBA/PIC + BigQuery/Tableau data to expose value gaps. 24 initiatives co-created with ROI, effort, and step-by-step roadmap. Auto-generated board decks, RFPs, process maps, Jira epics. Digital Twin monitors processes in real time, flagging leaks and duplications.
The Results
Impact highlights: $2.3M+ projected annual savings (12k-13k hours automated), 76 FTE equivalents avoided, 3,471% ROI achieved in the first month, 24 initiatives prioritized (all ROI >150%), first implementations live in under 1 week.
Cross-country benchmarking revealed hidden duplications and best practices. Proof of adoption: 80+ Superconsultant interactions, 200+ platform accesses across 20 users, 100+ stakeholders actively engaged in review processes.
