Overview

This article explains the key checks for buy-side legal due diligence in startup acquisitions, including shares, contracts, IP, labor, personal data, disputes and permits.

Key points

• Startup due diligence often requires checking both legal documents and actual operations
• Shares, stock options and founder rights should be reviewed early
• Key contracts, change-of-control clauses and IP ownership can affect valuation
• Labor, privacy, disputes and permits should be tied to post-closing risk

Practical perspective

In practice, this topic should be reviewed together with the transaction structure, internal approval flow, counterparty relationship, business priority and risk tolerance. Generative AI can support initial organization, comparison and drafting, but attorneys or the legal team should remain responsible for final legal judgment.
