I grow enterprise B2B SaaS accounts through renewals, pipeline rigor, and technical CRM automation.
BrazilWhat I'm looking for
At Ailet, I manage a $1M+ ARR portfolio across 12+ Fortune 500 accounts in seven Latin American countries, including Coca-Cola, AB InBev, Walmart, and Nestlé. I own contract lifecycles, renewal pipelines, and in-house technical integrations.
I co-led C-level negotiations that delivered 13.3% ARR growth and reduced churn by 25.2%, while maintaining accurate forecasts and CRM data. Previously at WATTio, I ran the full B2B SaaS sales and renewal cycle for a renewable-energy platform and helped drive 55% revenue growth.
I also built ICP segmentation, automated prospecting, and BI forecasting dashboards at ASAAS. I bring an engineering mindset to account management, using Python, Salesforce, and HubSpot across Tech, Finance, and Aviation.
