Protostar Inc. (Headquarters: Chuo-ku, Tokyo; Representative Director: Hidemaro Maekawa), whose mission is to support challengers, has released a practical 'Startup M&A Implementation Guidebook (over 70 pages)' that systematizes the knowledge accumulated over approximately one and a half years through its startup M&A support program 'STARTUP M&A Circulation'.
## ■ Background: Current State of Startup M&A
The Japanese startup environment is undergoing a major transformation. Since 2021, a series of large-scale M&A cases worth tens to hundreds of billions of yen have occurred domestically, and the government's 'Five-Year Startup Development Plan' also lists M&A activation as a key priority. This accelerates the shift from an 'IPO-only' approach to an 'exit and growth strategy through M&A'.
However, while market expectations are rising, a significant gap still exists in practical implementation. The M&A process is extremely complex, and unique business practices and know-how are 'black-boxed,' causing many executives to feel anxious due to a lack of decision-making information.
Our company has released this guidebook to remove the barrier of 'information asymmetry' and create an environment where challengers can take the next step with correct knowledge.
## ■ Contents of This Guidebook (Partial Excerpt)
This guidebook focuses not just on theory but on the 'first step' based on practical on-site experience.
- Overview of startup M&A and latest trends
- Solutions for 'information asymmetry' faced by both sellers and buyers
