Takumi Okoshi of Angel Round Unveils 'Solid Venture': A Blueprint Based on the Strategy of 80% of Profitable IPOs

Overview

Angel Round Co., Ltd. has announced the upcoming release of Solid Venture on October 28, 2026, authored by CEO Takumi Okoshi. Moving beyond the traditional binary categorization of companies as either "startups" or "small businesses," the book introduces a management philosophy centered on the "state" of a business—specifically its operational resilience and the sustainability of its innovation.

Key Insights from the Book

Titled Solid Venture: Management that Never Collapses, Practiced by 80% of Profitable IPOs (ISBN: 978-4-7981-8938-3), the work systematizes methods for using cash flow from core operations as an engine for continuous experimentation. It introduces proprietary frameworks, such as the "Six Windows of Corporate Analysis," designed to help leaders objectively assess their company's current positioning.

Background and Expertise

Author Takumi Okoshi draws from an extensive dual background in corporate business development and venture capital investment. The book's foundation lies in practical, field-tested experience within service-based industries—such as consulting, HR, and advertising—where existing profitability is leveraged to nurture new ventures. It highlights the common traits of "solid yet aggressive" management that thrives without over-reliance on external equity or high-burn, deficit-heavy strategies.

Looking Ahead

Through this publication, Angel Round aims to provide entrepreneurs and executives with a strategic roadmap for identifying their current status and formulating next-generation growth strategies. The company plans to further promote the "Solid Venture" ethos—building businesses that are resilient to market shifts and capable of repeated innovation—through its online magazine and other digital platforms.
