• Data Leaks in the Age of AI: Are You Underestimating the Danger?

• Shadow AI and Insider Threats: What Every Startup Should Know by 2025

• Data breaches: The silent risk that threatens startups in Latam

‍

The recent data leak at XAi, led by former engineer Xuechen Li, is a clear warning for all technology companies: internal risks can jeopardize years of innovation and billions in investment. Shadow AI represents one of the most serious emerging risks of 2025, involving the adoption and use of artificial intelligence tools beyond the control and supervision of IT departments. Nearly half of Shadow AI incidents result in the exposure of sensitive data. Employees, using unauthorized apps, can share customer personal information, intellectual property, and employee data on platforms whose privacy terms or legal location are unknown to the organization, increasing the risk of regulatory and legal breaches.

The XAi Case: A Lesson for Everyone

‍

In August 2025, XAi sued Xuechen Li for exfiltrating trade secrets before joining OpenAI. Li had privileged access to the entire XAi technology stack and, after selling his shares, copied confidential information and source code from Grok, the XAi chatbot. The incident included sophisticated concealment techniques.

This case shows that even the most valuable employees can become internal threats, and that traditional security measures are not enough.

Stolen trade secrets include:

• Cutting-edge AI technologies.

• Complete source code related to the development of Grok.

• Private and unreleased language models, including development versions and custom models for SpaceX and Tesla.

All of this information could save other competitors “billions of dollars in research and development plus years of effort”.

Why should security be a priority for your startup?

‍

In today's environment, where innovation and growth increasingly rely on technology and data, many startups in Latin America underestimate internal risks. It's not just about protecting information: it's a matter of survival. Recent incidents show that a single leak can jeopardize years of work and the reputation of the entire company.

How to prevent data leaks in your startup?

‍

Within the Microsoft 365 suite we can find different products that, when combined with the right strategy, achieve a robust approach to the protection of sensitive information.

When using data loss prevention policies (DLP), Internal risk management policies (Insider Risk Management) and event alerts, startups can stop leaks and identify malicious actions within their internal teams.

77% of security teams adopted AI technology at the same time or faster than business teams, but the governance gap continues to expose critical risks. Don't wait to hear the news because of a data leak. Internal security isn't a luxury, it's a strategic need for any startup that aspires to grow and compete in the global market. Adopting a culture of protection and prevention can make the difference between success and failure.
