Stock is a Japanese information-sharing platform designed for teams to centralize knowledge without the overhead of chat logs or file-sharing friction. The product reached over 100,000 companies via organic adoption with zero advertising spend since its 2018 launch—a signal of strong product-market fit in small-to-medium teams. Current hiring focuses on engineering (particularly rebuilding and scaling the dev organization), sales infrastructure (go-to-market strategy, partner sales, sales ops), and executive leadership (tech strategy, customer success), indicating a shift from product-led to sales-led growth as they target enterprise adoption.

About 株式会社Stock

Stock operates a web and mobile information-management platform built on Ruby on Rails and React, with native mobile clients (React Native and Electron). The company was founded in 2014 and bootstrapped until 2020, when it secured its first external funding (¥100M) to accelerate growth. Based in Tokyo with a 2–10 person core team, Stock serves small and mid-market teams domestically and is preparing for international expansion. The product is positioned on simplicity and accessibility—intentionally usable by non-technical users without training. Current priorities include deploying generative AI into the product, scaling the sales organization for enterprise revenue growth (MRR/ARR targets), building customer success infrastructure, and expanding into non-IT enterprise segments.
