What Stock does

Stock, Inc. (株式会社Stock) is a Tokyo-based private SaaS company founded in 2014 that develops team information sharing and knowledge management tools specifically designed for non-IT enterprises. The company operates two core products: 'Stock,' a team information management tool optimized for organizations up to 100 users that consolidates customer meeting records, meeting minutes, task assignments, inquiry management, messaging, and task management into a single low-friction interface; and 'ナレカン (Narekan),' an AI-powered knowledge management platform for organizations of 100 to tens of thousands of users that offers high-precision internal search, automated knowledge accumulation, and generative AI features designed to keep internal knowledge accurate and fresh.

The company runs a primarily product-led growth (PLG) model with a self-serve digital distribution channel, supplemented by a sales-led motion with dedicated sales (セールスSTEams) and customer success (CSチーム) teams for the enterprise Narekan product. Stock has reportedly reached 250,000+ corporate customers with minimal paid advertising, relying on organic word-of-mouth, content marketing (company introductions, member interviews, founder stories), and social media. Revenue is generated through tiered SaaS subscriptions aligned to team size, and the company holds ISO 27001 and ISO 27017 certifications supporting enterprise-grade security positioning.

Stock has disclosed one funding round of approximately $943,650 (September 2020) from DNX Ventures, East Ventures, Infcurion, and Money Forward. With 11-50 employees, the company maintains a lean operating structure while serving a horizontally segmented Japanese SMB and mid-market base across non-IT industries including manufacturing and construction (e.g., Sanko Metal Industry / 三晃金属工業). Geographic operations are concentrated in Asia, though the corporate mission references a 'worldwide' non-IT enterprise audience, indicating latent international expansion optionality.
