Investors turn data provenance into transaction diligence

On September 21, The Wall Street Journal reported that venture investors and acquirers are increasingly checking whether specialized data used to fine-tune vertical AI products was lawfully licensed and collected with appropriate consent. The report cited a Gunderson Dettmer transactions and licensing partner and was accessible only in limited form, so it supports the diligence trend rather than a quantified market-wide finding. Legal-tech companies should expect data lineage, license scope, deletion rights and model-training permissions to move from technical appendices into financing and acquisition diligence. The second-order effect is that a well-documented content supply chain may support valuation, while unclear provenance can create indemnity demands, price adjustments or a blocked deal.
