I founded MultHub in 2017 as the sole partner and CEO, building a SaaS business that launched more than 10 products and generated R$ 20 million in revenue. I led the sale of the company to SolarMarket and completed my exit from operations.

At MultHub, I shaped product vision, discovery, roadmap priorities, and go-to-market. I positioned MultHub.com as a B2B SaaS CRM for AI-powered customer service, marketing, and sales automation, reaching more than 1,000 subscribers and NPS 83.

I managed product and business metrics, including CAC, LTV, churn, ROI, and ROAS, and was responsible for the company and product P&Ls. The business reached more than R$ 300 thousand in MRR, with 2,000+ simultaneous paying subscriptions and a team of up to 16.

From 2019 to 2025, I taught MBA courses at Business Behavior Institute of Chicago on Growth, go-to-market, monetization, product management, and finance. I also use AI, APIs, MCPs, and webhooks for automations, prototyping, tests, financial analyses, real-time dashboards, and web-application MVPs.
