  Co-founder & CEO (Growth, Product & Strategy) @ MiPrimeraChamba.ai

  Mexico City, Mexico - Hybrid

  Summary:

  • Co-founded MiPrimeraChamba.ai, an AI-powered job matching startup for LatAm built as a 'compass' rather than a marketplace: 4-dimensional matching (culture, geolocation, interests, and skills), human verification of companies and job posts (KYC as protection against fake or dangerous listings), and a gamified development path when there is no match.

  Responsibilities:

  • Led the growth strategy: high-velocity acquisition funnel (4-level value ladder), urgency triggers, and GA4 implementation with prospect-to-call conversion tracking
  • Designed an AI agent-based direction system (Growth, Product, Marketing) to prioritize and execute sprints focused on product-market fit
  • Owned organic go-to-market: co-organizer of AI CDMX monthly community, talks at ESCOM, job fairs, and alliances with CANACINTRA/CONCANACO plus own events
  • Led the timing thesis, the business model (Gen Z freemium + Gen X premium + B2B labor data), and investor positioning

  Achievements:

  • First sale before the SaaS existed, validating demand in week 1
  • 40% conversion from discovery call to upsell across 74+ user interviews
  • Won 1st place at Platanus Hackathon CDMX (prize: trip to Chile), 3rd place SEDECO CDMX, and Incubathon Web3
  • Built an organic community-led acquisition engine across AI CDMX, ESCOM, and business chambers
