Here's what Natasha chatted about today:Big tech: Good news for Bitcoin and Ethereum, even as late-stage companies in the space cut to stay afloat.Big idea: I had two ones to get through. First, Africa had no new unicorns last year, despite record fundraising raising. What's that all about? Second, I want to talk about Stripe's internal valuation cut, yet again, and what that news means on the outside.Big innovation: I talk about yet another Clearco executive shake up and yet another Clearco round of layoffs, as well as the energy for the fintech moving forward. We end with a look at freshly-backed T2, which is opening up its game plan in a spreadsheet format. We love to see a Twitter rival, love even more to see one utilize the beauty of read-only spreadsheet featuresAs always, you can support me by following me on Twitter and Instagram. The show also tweets from @equitypod, so follow us there and turn on notifications to never miss a new update from your favorite podcast team in tech (ugh, you shouldn't have).Equity drops at 10:00 a.m. PT every Monday and at 7:00 a.m. PT on Wednesdays and Fridays, so subscribe to us on Apple Podcasts, Overcast, Spotifyand all the casts.
