Carter Reum co-founded M13 in 2016 with his older brother, Courtney. The early-stage venture capital firm now has $1.3 billion of assets under management with over 40 staff working in offices in New York, Santa Monica, and San Francisco.
The brothers started their careers as bankers at Goldman Sachs before founding VEEV, a spirits company later acquired by Luxco. In 2021, Carter’s life became much more public when he married Paris Hilton. Two years later, they had a son and a daughter.
Reum spoke to BI, sitting on a couch in their 15,000-square-foot “dream house,” which includes a wellness center, a room dedicated to opening packages, multiple studios, and pictures of Hilton on seemingly every wall. Soon, they will move next door to a Beverly Hills home twice as big. Once owned by actor Mark Wahlberg, it features a water slide and a 5-hole golf course spread across six acres.
Here’s how Reum spends his day. This as-told-to essay has been edited for length and clarity.

I start the morning with cold brew and write down my priorities for the day
I’m usually up at 7 am and grab a cold brew from my Cumulus Machine.
I always tell founders they should have a microscope in one eye and a telescope in the other. What I mean by that is get the stuff done you need, but also zoom out. So the first thing that I do when I’m sipping my coffee is write down a few tactical things I need to make sure I get done, and then one or two bigger things that are top of mind. I try to do that before I jump into my inbox because the minute I jump in, I’m reacting to what everybody wants.
The downside of living on the West Coast is that the minute you wake up, people are waiting for you. You receive a lot of texts, WhatsApp messages, and Slack messages.
One of the things that really stuck with me is that years ago, someone told me, “Don’t let your inbox be your to-do list.” It means that everyone else is demanding your time. You should define what you want to spend your time on.
I’m a Superhuman user, and I find it helpful to start with the things that have been flagged as important because when I wake up, I might have a few hundred emails waiting.
On any given day, I probably have two calls with founders on Zoom to hear how things are going. I always want to hear from people on the bad days more than the good days. That’s because it’s easy to talk about the good days, but if you can create a culture where people bring you the problems and give you the opportunity to talk through them and try to fix them, it leads to better outcomes.

I enter my cryochamber twice a day and take Zoom calls from my hyperbaric chamber
Ben Bergman/BI
I’m a big believer that wellness is all about the power of compounding.
I have a “wellness longevity center” down the hall, and it will be even larger in the new house.
I think I was the first person to install a commercial cryogenic machine in a house. I do that twice a day, and so by the end of the year, I’ve gone 700 times.
I also try to go three times a week in my hyperbaric chamber and an hour of Zoom meetings in there, and then I try to do the red light bed five times a week.
If you look back 10 years, in a place like Los Angeles, when you would walk into a house, there would be a screening room, and that was really cool. A lot of people have them now.
In the next 10 years, I think you’re going to see a lot more home wellness areas. Some of the equipment is expensive, but if you think about what we all spend money on, you go, “Would I rather go on vacation or buy a red light bed? Would I rather buy a Tesla or a cryo chamber?”
I’m a big fan of intermittent fasting and cooking simple meals at home with my wife
I intermittent fast, so I don’t eat until the afternoon, when I usually order something healthy on Postmates.
Paris makes a killer turkey sandwich, and so some days for lunch, she’ll make me her homemade turkey sandwiches and slide them under my monitor when I’m on a Zoom. Those are the good days.
Paris and I love to cook, but it’s mostly because it’s a time when we get to hang out. So we’ll make Turkey tacos or grill chicken.
I end every day putting my kids to bed and taking a bath with my wife

My two kiddos are two and a half and one and a half. Right before they go to bed when they’re in their cute little PJs, they’re not rambunctious, and they just want to cuddle and read books.
The kids go to bed around seven, and I’ll come back and do a few hours of work. Paris tends to finish up relatively late, too. Then, one of us will send the message to the other to turn the bath on. We have a big bathtub, so it takes about 40 minutes to fill up, so we have to plan ahead.
We take a bath every night because it’s the one time we can’t have devices, so we’re very present. So she’ll say, “How was your day? What’s going on?” I’ll ask about her day.
Paris and I also love to do ab or pushup challenges. We’ll do a lot of the eight-to-12-minute workout challenges before bed.
Before I go to sleep, I launch an AI agent
I realized in the early days of AI that it had to be part of your day-to-day routine. So I created a Slack channel for M13 called AI Hacks
I try to lead by example of creating a culture of obsessing over AI, so I won’t go to bed until I’ve launched some agentic AI. It could be something personal, like, “I’m thinking about going away next week. Can you research the hundred best hotels?”
I went to a conference and took photos of all the attendees on a flat screen. I said, “Can you create summaries of all the attendees and highlight the ones you think I should follow up with?”
A few months ago, it was pretty disappointing, meaning the AI just wasn’t there. But now, when I wake up in the morning, someone else has done some work for me, and it’s pretty good.
At M13, we create AI summaries of all of our Slack channels and our entire portfolio, and we have custom GPTs that spit out reports across the firm on everything going on. When I think about our portfolio, I don’t have to ask, “How’s that company doing?” The AI will alert me if it’s doing exceptionally well or poorly.
I believe the best VCs will become even better in the future because of access to data and AI.
When you think about this Power Hours series a year from now, I think the way I organize myself will seem archaic in a very short period of time because so much of how we all spend our days is trying to figure out where we should prioritize our time and our effort. We either have someone else do that or we try to do that ourselves, but AI tools will do that.
