Yellow Rocks!
Yellow Rocks! operates as a venture capital firm from San Francisco, investing primarily at the seed and early stages. Founded by Managing Partner Sergei, the firm deploys capital into technology startups that build category-agnostic software platforms. Its publicly listed portfolio spans AI, Web3, enterprise SaaS, and EdTech. The team also includes Partner Roman, Venture Partners Valerie, Slava, and Dmitrii, alongside a small operations and legal staff. Portfolio companies confirm a high-volume, multistage venture strategy. Active positions include Praktika.ai, an AI language-learning app; Chatfuel.com, an AI operating system for service SMBs; and RealFin.io, a blockchain network for tokenized financial assets. The firm's geographic reach is broad — it backs companies headquartered across the United States (Viewst.com, Jome.com), Brazil (TraiveFinance.com), and Southeast Asia (Getmo.tech). Deal structures appear to favor direct equity, with seed-stage entry points. Yellow Rocks! does not disclose assets under management or total deployment to date. Its team of eight named professionals suggests a lean partnership model common among early-stage venture firms. The firm's website hosts no separate philanthropic vehicles or operating companies. No LinkedIn corporate page was publicly available at the time of review, placing a premium on its own website as the primary source for portfolio holdings and team composition. What distinguishes Yellow Rocks! is its portfolio transparency amid a sector where many seed-stage firms operate with minimal public disclosure. The firm openly lists over three dozen active companies alongside its investment team, a structural choice that signals sourcing breadth to co-investors and founders. This posture functions as a direct marketing mechanism within the competitive San Francisco venture landscape.
