JB Straubel was Elon Musk’s battery guy. Now he’s trying to turn what some see as trash into power for the electric vehicle revolution. Straubel was there at the earliest days of Tesla, and in his 15 years with the electric vehicle company, he played an integral role: he developed the battery pack used in the first Tesla vehicle, was the company’s Chief Technology Officer, and now sits on the board of directors. But his day job is running the battery-recycling startup Redwood Materials, and he envisions a future where recycled batteries power our cars, cell phones and power tools. So could companies like his one day replace the oil giants who fueled the last century? Why does he think humans have room to work harder? And can the Tesla board manage Musk as he takes on a growing role in U.S. politics, including advising the Trump administration? Straubel speaks to WSJ’s Tim Higgins and Christopher Mims in episode three of our interview series Bold Names.

Marc Benioff is one of the most outspoken names in tech. The billionaire co-founder of customer relationship software company Salesforce has been pivoting the company’s focus to artificial intelligence agents to help its clients manage customer service and other needs. But he has some strong opinions about how others are promoting AI, from how Microsoft is selling its Copilot feature to companies like Amazon buying up nuclear power contracts for their data centers. And yet he says he’s as excited about AI as he was the day that Apple’s Steve Jobs sent him one of the first iPhones. So what can AI actually do, and what’s a ‘fantasy’? Benioff speaks to WSJ’s Christopher Mims and Tim Higgins in episode two of our interview series Bold Names.

Tesla, and its CEO Elon Musk, are the big names in electric vehicles, but a lot of competitors are nipping at their heels, including one led by a former top Tesla engineer. Peter Rawlinson is the CEO of Lucid, a billion-dollar auto startup he says has better technology than its rivals. The company recently completed a $1.75 billion stock offering, and has backing from Saudi Arabia’s Public Investment Fund. Now, as major automakers such as Volkswagen, General Motors and Ford pull back on their EV ambitions, find out why Rawlinson says Lucid’s all-in on luxury vehicles with a high price tag and, eventually, smaller batteries. Plus, why he says he won’t be building a $20,000 EV any time soon. He speaks to WSJ’s Tim Higgins and Christopher Mims in episode one of our interview series Bold Names.
