Summary
👤
Senior🎓
Top SchoolDavid Sb is a founder and seasoned technology leader with 15 years of experience building and scaling product-led engineering organizations across fintech, social media, and enterprise SaaS. He grew Vórtx from early stage to a market-leading fintech platform—scaling ARR fourfold, AUM sevenfold, leading Series B funding, multiple M&A and launching regulated tokenization—while turning a 3-person team into a 60-strong engineering and product organization. Equally comfortable in code and strategy, he led NLP and information-retrieval efforts at Scup/Sprinklr and has a history of open-source and early AI experimentation (including GPT-3 and AWS ML initiatives). Today he splits time between a master’s researching complex/virtual societies at USP and quietly building an AI+fintech startup in stealth, reflecting a blend of academic rigor and operator grit. A founding member of Confraria Tech, he helps convene 1,000+ CTOs and tech leaders in Brazil, amplifying his influence beyond any single company. Notably, his background spans global engineering contexts—from Tokyo and Los Angeles to São Paulo—bringing practical distributed-systems and product-first sensibilities to high-impact problems.
