If you spend any time inside a company that actually makes things in the U.S., then you’ll hear about SendCutSend.
Started in 2018, SendCutSend has become an American manufacturing phenomenon. The company makes metal parts for more than 300,000 customers, ranging from giants of aerospace and defense to hobbyists working on their cars. You ship SendCutSend a computer file of what you want built, and it often arrives at your house or factory the next day.
Jim Belosic started the company because he always had hardware side projects running in the background and wanted something like SendCutSend to exist. He spent $750,000 on his first metal cutting machine and then soon discovered that there were lots of other people like him who also wanted something like SendCutSend to exist.
The company has since evolved into one of the few homegrown options that can compete with China in terms of getting metal parts to customers quickly and at a reasonable price.
SendCutSend had been flying under the radar of the wider public for years with Belosic building the business largely with his own money and some smaller investments. Recently, though, SendCutSend raised $110 million from Sequoia, Paradigm, and Stripe founders Patrick and John Collison is now valued at $1 billion.
Our interview with Jim was conducted at SendCutSend’s headquarters in Reno and covers his history, the company’s history and the state of manufacturing in the U.S.
Full Disclosure: SendCutSend is a sponsor of the Core Memory podcast. This interview, for what it’s worth, took place before the company came on as a sponsor when my brain and soul were still objective.
Jim and I subsequently found a lot of overlap in what we care about and how we go about things. Our readers and viewers will know that we’re rather into folks who make things, and so is SendCutSend, so it’s quite the natural fit.

Did Kylie and I attend the Midjourney Scanner event? Yes, we did. Did Kylie compare notes on her skincare routine with Bryan Johnson at the event? Also, yes. Meanwhile, I formed more wrinkles by downing cocktails while all this happened.
Since the Midjourney pivot into medical devices and health spas is all the rage, we had no choice but to dive right in on this week’s episode. We also explored the government’s ban of Anthropic’s latest model, the odd tie-up between DeepMind and Eve Online, Noam Shazeer leaving Google for OpenAI, Snapchat’s Snapcrap glasses, the Rafael Nadal documentary (naturally) and a robot that kills fish in the name of better sushi.
Come get it.

Max Hodak is back.
The co-founder and CEO of Science Corp. joined me for our first-ever live podcast recording, which took place at the Brex headquarters in San Francisco. Thanks so much to all the Core Memory subscribers who turned up.
Max walked us through Science’s technology aimed at restoring vision in the blind, and the company’s new product lines focused on organ transplants and extending the abilities of brains. So, like, totally normal, everyday stuff.
Mostly, we talked about the merger of humans and machines and the progression of bio-tech and AI technology.
We’ve had Max on the show twice now because, for our money, he’s one of the most daring minds in the neuroscience and bio-tech fields, and there’s a decent chance that Science becomes one of the most fascinating companies in the world.
Thanks, of course, to Brex for hosting this event and to you guys for all the great questions.

The theme for this week’s episode is tick, tick, boom.
America is running out of time to catch up with China on manufacturing, and we’re physically incapable of spending an hour together without bringing it up. Release the glorious machines please!! We also go behind the scenes on Kylie’s reporting on motors and actuators — the unglamorous parts that sit in every joint of a humanoid robot, account for roughly 60% of what that robot costs to build, and come almost entirely from China. Her piece profiles the two startups trying to change that. Plus a new proposed bill out of Congress that would kick Unitree’s robot doggies to the curb.
Then the rockets send Ashlee off on his space tangents. Jeff Bezos’ Blue Origin had an expensive mishap recently when an explosion took out the rocket, its launch pad, and possibly America’s dreams of beating China back to the moon. Ashlee walks through why a pad explosion can be a near-death moment for a rocket company, and why SpaceX — now flying roughly every two days while everyone else is grounded or behind — increasingly just wins by default. Plus the new Starfall capsule, SpaceX’s move into making medicine and maybe chips in orbit, and the wild logic behind a $1.77 trillion IPO.
We also got into the media drama consuming our X timeline: the firing of Scott Pelley from 60 Minutes. Ashlee tweeted an opinion, the trolls came for him hard, and he pleads his case here. We’re a little biased since, well, we’re off building this whole new-media thing ourselves. Will there still be a ticking clock and a man in a suit raking in views twenty years from now? Tune in for what we think, and leave your hot take in the comments.

(Ed. Kylie - Don’t think I forgot to make you a playlist. “Lazy Eye” and “New Slang” were key to my college experience. I first crushed on Rivers Cuomo thanks to “Perfect Situation.” Listen to it here, and don’t forget to leave a comment to win tickets to their tour).

A couple of months ago, we went out to Nevada to hang with JB Straubel, the founder and CEO of Redwood Materials and the co-founder of Tesla. JB took us on a tour of Redwood’s massive battery recycling operations and showed us the company’s next chapter, which centers on building battery and solar farms to power AI data centers.
The result of our time with JB is a different style of podcast episode. You’ll probably want to consume this on the Substack, Spotify or YouTube where there’s video, and you can see what’s happening.
If you’re not familiar with Redwood, well, it’s up to big things. Around 70 percent of all the lithium-ion batteries that have reached their end of life make their way to Redwood’s facility where they’re then broken down into their base elements, including lithium, cobalt and nickel. Redwood stands as the largest cobalt producer in the United States and does this all from recycling. As in, zero mining.
Redwood is now taking car batteries that still have some life left in them and clustering them together alongside solar panels to create giant energy storage systems. Naturally, it’s aiming these systems at the AI set first, offering power that does not depend on the grid or turbines or anything else in short supply and high demand.
In this episode, we go through Redwood’s entire recycling process and check out its first storage system. Along the way, we chat with JB about Redwood’s history and the recycling business. It’s a banger.
