Financial Services Buenos Aires 51–200 employees Founded 2021 Privately Held

Cocos is a Buenos Aires–based fintech operating a unified investment platform across equities, bonds, funds, crypto, and FX for retail and institutional clients. The tech stack reveals a mobile-first, modern architecture (React Native, Node.js, PostgreSQL, ClickHouse) built for scale, with hiring weighted toward marketing (4 roles) and engineering (3) — a growth-stage signal — and active replacement of React suggesting UI/UX modernization underway. Pain points center on user acquisition and conversion optimization, paired with ongoing infrastructure challenges (performance, availability, vulnerability management), indicating simultaneous pressure to scale both product and operations.

About Cocos

Cocos operates Argentina's largest retail investment platform, with nearly 2 million users and over USD 2 billion in assets under administration. The product consolidates FX, mutual funds, bonds, equities, CEDEARs, and crypto in a single mobile and web interface, lowering barriers to participation through built-in financial education. Beyond retail, the company serves 2,300+ corporate and institutional clients—small to large businesses, independent advisors, agricultural sector players, and alternative market participants—with treasury, investment strategy, and custom trading tools. Founded in 2021 by Nicolás Mindlin and Ariel Sbdar, Cocos operates a profitable, capital-light model and is currently pursuing a banking license acquisition (subject to central bank approval) while preparing market entry in Mexico.
