Today on  Equity, Devin Coldeway kicked off our Deals of the Week rundown with Piramidal, a startup which offers a foundational model for analyzing brain scan data that just raised $6 million, as his deal of the week. The premise behind the company is a fascinating one in that its technology aims to help complement the work of nurses and doctors in neural ICUs by helping identify signs of things like an epileptic episode, or a stroke.

Mary Ann Azevedo wanted to talk about Comun, a neobank serving Latino immigrants in the U.S. with financial services and banking products. The fintech just raised $21.5 million a round led by Redpoint Ventures, not that long after closing its seed round. It’s seeing fast growth — as well as a higher valuation.

Rebecca Bellan dug into a scoop she had about Fluid Truck and recent drama there. The startup, which was founded to disrupt the commercial vehicle rental industry, has apparently ousted its sibling co-founders — CEO James Eberhard and chief legal counsel Jenifer Snyder — in what is being described as a hostile takeover.

We then moved into the arrest of Telegram founder Pavel Durov, and whether or not tech executives can, and should, be held responsible for what happens on their platforms. And lastly, we dug into what’s going at Inflection after Microsoft poached its co-founders. That move has drawn attention from antitrust regulators in the U.S. and U.K., who are now investigating whether Microsoft was anticompetitive. The Equity crew discussed whether or not companies are using acqui-hires to get around antitrust regulation.

Honestly, we had so much fun we could’ve gone on for a whole other episode. Give it a listen!
