5 investors discuss what’s in store for venture debt following SVB’s collapse

-
There are many questions around the implications of Silicon Valley Bank’s (SVB) collapse that won’t be answered for a long time. But there’s one question that many startups and investors are hoping will get answered sooner rather than later: What happens to venture debt? SVB was one of the larger, if not the largest, providers of venture debt to U.S.-based startups. And now that First Republic Bank has also gone under, that question has spiraled, growing ever more complex. Many startups rely on venture debt: it’s both a cheaper alternative to raising equity and can serve as a capital tool that helps companies build in ways that equity isn’t great for. For some companies in capital-intensive areas like climate, fintech and defense, access to debt is often the only avenue to growth or scale.

TikTok claims it’s not collecting U.S. users’ biometric data, despite what privacy policy says

-
Last year, TikTok quietly updated its privacy policy to allow the app to collect biometric data on U.S. users, including “faceprints and voiceprints” — a concerning change that the company declined to detail at the time, or during a subsequent Senate hearing held last October. Today, the tech company was again asked about its intentions regarding this data collection practice during a Senate hearing focused on social media’s impact on homeland security.  TikTok’s earlier privacy policy change had introduced a new section called “Image and Audio Information” under the section “Information we collect automatically.” Here, it detailed the types of images and audio that could be collected, including: “biometric identifiers and biometric information as defined under U.S. laws, such as faceprints and voiceprints.” The policy language was vague as it didn’t clarify whether it was referring to federal law, state laws, or both, nor did it explain why, exactly, this information was being...
