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. Thankfully, venture capitalists aren’t too worried about the SVB collapse’s impact on venture debt as a whole. We’re widening our lens, looking for more investors to participate in TechCrunch su...

Blockchain blockchain Malkovich blockchain

I spent much of last week at blockchain conferences, and I’m about ready to never hear the word again. This despite the fact I’ve been supporting decentralized software, as a counterweight or at least alternative to the growing power of governments and megacorps, for years now . Do you think blockchains are no answer? Great, let’s discuss! I wholeheartedly support you skeptics with whom I cautiously disagree. What I can’t stand, it turns out, is an endless sea of true believers nominally on my side . The believers are twofold, and the two groups grate differently. One group is there almost purely because there is money in the space: Wall Street types hoping to rule a new asset-tokenized world which may come to be; financial startups offering blockchain versions of existing financial tools; new marketplaces just like old marketplaces, except On The Blockchain, and therefore better. It’s all too easy to envision a future in which the collective vampire squid that is the financial indus...

Welcome back to This Week in Apps, the weekly TechCrunch series that recaps the latest in mobile OS news, mobile applications and the overall app economy. The app industry continues to grow, with a record number of downloads and consumer spending across both the iOS and Google Play stores combined in 2021, according to the latest year-end reports . App Annie says global spending across iOS, Google Play and third-party Android app stores in China grew 19% in 2021 to reach $170 billion. Downloads of apps also grew by 5%, reaching 230 billion in 2021, and mobile ad spend grew 23% year-over-year to reach $295 billion. In addition, consumers are spending more time in apps than ever before — even topping the time they spend watching TV, in some cases. The average American watches 3.1 hours of TV per day, for example, but in 2021, they spent 4.1 hours on their mobile device. And they’re not even the world’s heaviest mobile users. In markets like Brazil, Indonesia and South Korea, users ...
