Mitigating Key Personnel Turnover Risks with AI

In the fast-paced world of startups, the departure of critical engineers can be a significant threat, leading to project halts or strategic pivots. Rosetta Co., Ltd., led by CEO Junichi Goishi, has unveiled a new solution to this problem: the Metareal Brain Mirror (Metareal BM) premium plan, set to launch on September 10, 2025. This AI-driven agent is designed to predict the likelihood of key personnel departure and systematically replicate their knowledge. The cost of the premium plan is 50,000 yen per month (tax included), and it allows up to 20 uses per day or a total of 200 uses per month.

The Need for Metareal BM

The issue of knowledge evaporation due to employee turnover is particularly pronounced in the startup ecosystem, where individual engineers often hold unique algorithms or codes essential for product development. Traditional knowledge transfer methods usually rely on post-departure personal action, which is often too slow and inadequate, leading to unacceptably high management risks. Metareal BM was developed with the innovative idea of duplicating a person's knowledge before they leave.

Key Features of Metareal BM

Metareal BM incorporates several groundbreaking features to effectively tackle the problem of employee turnover:

1. Predicting Departure Risk: By analyzing metrics such as pull request frequency and custom code ratio, it estimates the likelihood of an employee's departure. A “resignation warning score” is calculated dynamically based on code contribution levels and activity.

2. Automated Code Documentation: Utilizing large language models (LLM), it generates comprehensive documentation that explains the code in natural language while covering its structure and intent.

3. Incentivized Review Process: Once the code documentary reaches 85% completion, it prompts a review from the original developer, who is incentivized to approve the documentation with rewards. This approach aims to keep motivation high throughout the knowledge transfer process.

4. Proactive Knowledge Preservation: By transitioning from reactive to proactive knowledge management, Metareal BM ensures preparations are completed three months prior to any anticipated departures.

These innovative features aim to minimize risks associated with turnover, enhancing the stability and continuity of startups.

Target Audience

This service is particularly beneficial for startup CEOs and CTOs aiming to reduce turnover-related risks, tech leads dealing with the challenges of documenting specific algorithms, HR managers seeking advance notice of potential resignations, and VCs looking to assess the technological continuity of their portfolio companies.
