Two VCs See Trading Cards as a Great Investment and are Starting a Fund to Trade Them

As early investors in buzzy startups like Lyft, SpaceX, Pinterest and Ring, Courtney and Carter Reum have gained a reputation as successful venture investors. Now they are devoting some of their attention and dollars to a decidedly lower tech investment: trading cards. After dabbling in cards as a hobby since they were kids growing up in the Midwest, the brothers want to use what they have learned as VCs to start a fund to procure undervalued cards they hope will someday score big returns.

"Applying that kind of rigor to something that has usually been done by young kids or emotion...I think that's how you get unfair advantages and outlier results," explained Courtney Reum. "I don't want to just dabble a couple hours a week. I want to be with people who really want to actually do this in an analytical way."


The Reums are making what they describe as a "meaningful" contribution to a multimillion dollar fund called Mint 10. They view it as a way to diversify their holdings away from illiquid shares in startups that won't pay off for years – if they're lucky – and equities, which they see as overvalued.

"I see this as a great alternative class, somewhere closer to a stock, albeit a little less liquid but more so than my venture and private equity stuff," said Courtney Reum. "To me, there's not much to find in the stock market that's a good deal."

A study last year showed baseball cards had a far superior return to stocks over the previous decade. The pandemic has triggered a frenzy in the card market, with huge spikes in trading and new records for coveted NBA rookie cards fetching more than a million dollars apiece.

The Reum brothers founded their Santa Monica-based early-stage consumer technology venture firm, M13, in 2016, after they sold their spirits business, Veev, for a hefty multiple to a St. Louis beverage conglomerate. M13 is now deploying its $175 million second fund backed by Virgin Group founder Richard Branson.

Reum thinks the still stodgy card industry is ripe for a shake up, eyeing big potential in influencers and creating content around the practice of "case breaking," the act of opening card boxes, which can draw big audiences on streaming platforms.

Reum, who remembers his mother driving him to card shows when he was 14 years old, views trading cards as similar to art, sports teams, Bitcoin or gold, which he's "bought a bunch of lately." What do all those assets have in common? There's a finite supply, which Reum believes inevitably drives the price up over time.

"I generally believe that something like gold or baseball cards, depending who you are, could be a couple percent of your allocation, up to like 10 percent," Reum said. "I think this is just as viable as gold or bitcoin or any of that."

Mint 10 will hedge its bets by buying a mix of cards from the three major sports that are both old and new.

"It's no different than how a long/short fund does their allocations," Reum said. "We have LP [limited partner] interest coming out of our ears."

Reum would not specify how large the fund will be or what his and brother's contribution is, owing to the fact that they are still fundraising. "It will be a multi-million dollar fund but we haven't finalized the amount yet," he explained. "We have a lot of interest but we want the strategy to dictate the raise vs the inverse, which is sometimes the case."

Courtney and Carter Reum are devoting some of their attention and dollars to Mint 10, an investment fund focused on trading cards.

The Reums are not alone in their newfound enthusiasm for trading cards. Just as people bored at home with extra cash in their pockets drove a wave of day trading, card sales have been on a tear during the pandemic.

During the first few months of the coronavirus outbreak, sales of basketball cards on eBay spiked more than 130%. Baseball cards saw a 50% spike while football cards had a 47% increase.

In July, a LeBron James rookie card shattered the record for a modern day NBA card, going for $1.8 million. But the record stood for only a few months as last month a card of Milwaukee Bucks forward Giannis Antetokounmpo fetched $1.812 million. (The card previously sold for $7,000 on eBay, but the buyer reportedly returned it because of a yellow stain.)

"I think you're going to see sales records over the next 12 to 16 months that shock the world," said Scott Keeney, a DJ, entrepreneur, and trading card expert who the Reums brought in to run the new fund. "I've seen more VC activity in the last four-to-six weeks around the card space than I would have ever dreamed."

Keeney compares Mint 10 to funds trading fine art, but he sees a much bigger upside in cards because of people like Reum, who have traded them since they were kids.

"This generation who grew up in the Junk Wax Era now has disposable income to spend," Keeney said. "Would they rather spend all this money on a piece of art that hangs on the wall that they might not be that tied to? Or do they want to own Magic Johnson's rookie card if they're a Lakers fan?"

Though most trading is done online these days, Keeney, along with fellow DJ, Steve Aoki, opened a brick and mortar card card shop last month in Hollywood, Cards and Coffee, featuring over $2 million worth of inventory.

With a widely accepted grading system and limited supply, the trading card market has come a long way from the scandals that scared away collectors in the 20th century. But the industry still has problems. Last year, the FBI launched a criminal investigation into the world of baseball card collecting that included the largest seller of cards on eBay.

"This doesn't sour us on the market one bit," Reum said. We are obviously aware of this process of attempting to cheat the system, and are diligent in research to avoid this scenario. However, we actually are glad this incident came to light and was taken seriously by the FBI."

The Card Reum Will Never Sell

On a recent Zoom video call conducted just after he had returned from a business trip to Austin, Reum excused himself and said there was something he wanted to show. He darted off screen and returned holding up a framed oversized 1985 Michael Jordan Interlake card.

He pointed to the bottom right hand corner where the words "Interlake Youth Incentive Program" were printed in small lettering. The card holds a great deal of significance for Reum because his father, W. Robert Reum, was an executive at The Interlake Corporation before becoming president and CEO in 1990.

The company signed on as a corporate sponsor of the Bulls in 1984. As someone who now spends a lot of time thinking about how consumer-focused startups should market themselves, the move still baffles him.


"Given they were a B2B diversified industrials company, whomever was running their marketing probably should have been fired for such a sponsorship," Reum laughs. "The Bulls were the worst team in the league, there was no internet for people to discover the company, and it was hard to see how the sponsorship would help sales of Interlake products. However, the sponsorship did come with eight floor seats. The year following the deal, the Bulls drafted Michael Jordan and the rest is history."

W. Robert Reum died two years ago at the age of 74 from complications from cancer and Reum has a hard time not getting choked up looking at the card.

"To me, it is a really personal way to honor my dad," he said.

The card is worth around $20,000 and could soar in value to half a million dollars if it is seen as Jordan's rookie card, according to Keeney. But this is one card Reum will never sell. He wants to acquire more of them.

This Torrance Startup Just Raised $1B to Mass-Produce Hypersonic Missiles

🔦 Spotlight

Happy Friday, Los Angeles.

Castelion has spent the past four years trying to prove that hypersonic missiles do not need to take decades to develop or cost so much that the military can only afford a limited supply.

Now comes the harder part: producing them at scale.

The Torrance-based defense startup raised a $1B Series C at a $13B valuation. The financing includes $800M in equity and a $250M revolving credit facility, making it one of the largest recent raises for an LA defense technology company.

JPMorganChase’s Strategic Investment Group, Andreessen Horowitz and Carlyle co-led the round. Lightspeed Venture Partners, Lavrock Ventures, Altimeter, General Catalyst, T. Rowe Price and LA-based Interlagos Capital also participated.

Castelion will use the capital to ramp production of Blackbeard, its low-cost hypersonic strike missile, while developing a longer-range precision weapon and new defensive systems. Hundreds of millions of dollars will go toward expanding manufacturing at Project Ranger, the company’s 1,000-acre production campus in New Mexico.

Image Source: Castelion

Blackbeard was designed in California, will be built in New Mexico and is expected to enter service in 2027. Castelion says it has already secured more than $500M in U.S. military contracts over the past 18 months and moved the missile from a clean-sheet concept to an official program in fewer than four years.

That timeline is central to Castelion’s pitch. Traditional defense programs are often associated with long development cycles, limited production runs and eye-watering costs. Castelion is applying the rapid testing and vertically integrated manufacturing approach popularized by commercial space companies to weapons production.

But a $13B valuation changes the standard. Castelion is no longer being judged as a promising startup with an impressive prototype. It is being funded like a company expected to become a major part of the American defense industrial base.

The question is no longer whether a startup can build a hypersonic missile. It is whether one can manufacture thousands of them without losing the speed, discipline and cost advantages that made it disruptive in the first place.

For LA’s defense ecosystem, that shift matters. The region has become home to a growing number of companies promising to modernize how America builds critical hardware. Castelion now has the capital, contracts and facilities to show what happens when that promise reaches the factory floor.

The next test will not be in a pitch deck. It will be in production.

      Why Samsonite Just Paid $178.5M for BÉIS

      🔦 Spotlight

      Hello, Hello.

      This week, one of LA’s most recognizable consumer brands packed its biggest bag yet.

      Samsonite Group has agreed to acquire an 85% stake in BÉIS for $178.5M, valuing the Los Angeles-based travel and lifestyle brand at approximately $210M. The deal is expected to close in Q4, pending regulatory approval.

      Founded by actress and entrepreneur Shay Mitchell and incubated by LA-based Beach House Group in 2018, BÉIS has grown from a digitally native luggage startup into a profitable business that generated approximately $210M in sales last year. Along the way, it built the kind of fiercely loyal online following that legacy brands spend years and considerable marketing budgets trying to manufacture.

      Image Source: BÉIS

      That may be the most interesting part of this deal. Samsonite is not simply acquiring another luggage line. It is buying access to a younger, predominantly female customer base, a sophisticated direct-to-consumer operation and a brand that knows how to turn social media attention into actual sales. The suitcases are useful; the cultural relevance is the real carry-on.

      BÉIS will continue operating as a standalone brand under CEO Adeela Hussain Johnson and its existing management team. Mitchell will retain a 15% ownership stake and continue guiding the company’s creative and product vision, while Samsonite brings the global distribution, sourcing and logistics infrastructure needed to take the brand further.

      For LA’s startup community, the acquisition is another reminder that valuable technology companies do not always look like software companies. BÉIS built its advantage through digital distribution, community and an unusually sharp understanding of its customer. Now, one of the world’s largest luggage companies wants what it created.

      Sometimes the strongest exit starts with knowing exactly what people want to pack.

          Two LA Startups Raised $2.37B to Build What AI Needs

          🔦 Spotlight

          Happy Friday, LA.

          The largest checks in tech are increasingly going toward companies trying to build their way out of America’s biggest physical constraints.

          This week, two Los Angeles startups raised a combined $2.37 billion in equity to tackle two particularly urgent ones: how the country manufactures critical hardware and where it will find enough electricity to power the AI era.

          Torrance-based Hadrian is building highly automated factories for defense and aerospace. El Segundo’s Valar Atomics wants to manufacture nuclear reactors at scale. Different industries, same underlying bet: the next generation of technology will depend on our ability to produce physical infrastructure much faster than we do today.

          Hadrian raised $1.37 billion in Series D funding, bringing its valuation to $7.87 billion. The company plans to use the capital to open new factories, expand research and development, and increase its capacity to produce critical defense, aerospace and industrial systems.

          Hadrian’s pitch is straightforward, if wildly ambitious: America needs to relearn how to build things and build them quickly.

          Its factories combine skilled workers with AI, robotics and proprietary software to manufacture precision components and, increasingly, complete mission-critical systems. Its customers include defense giants such as Lockheed Martin and RTX, along with newer players like Anduril.

          The company has come a long way from simply making aerospace parts. Hadrian is positioning itself as a piece of America’s industrial infrastructure, offering manufacturers a way to rapidly scale domestic production at a time when wars abroad, strained supply chains and growing defense demands have made the country’s manufacturing gaps increasingly difficult to ignore.

          Investors are clearly buying the argument. The new round comes just over a year after Hadrian raised $260 million, suggesting that “reindustrialization” has officially graduated from venture capital buzzword to billion-dollar investment thesis.

          Meanwhile, roughly 15 miles away in El Segundo, Valar Atomics is moving even faster than its enormous ambitions suggested.

          When we last wrote about Valar, the company was reportedly raising $450 million at a $2 billion valuation and racing to prove that nuclear energy could move on AI’s timetable. Now, it has closed a $1 billion Series B led by Sequoia Capital, secured an additional $200 million credit facility and reportedly reached a $6 billion valuation.

          Valar is developing standardized, factory-built nuclear power plants designed to avoid the enormous costs and decades-long construction timelines associated with traditional nuclear projects. Its goal is not merely to build a working reactor, but to eventually manufacture fleets of them.

          That ambition also sounds considerably less theoretical than it did when we first covered the company. In June, Valar’s Ward 250 reactor achieved a self-sustaining nuclear reaction. Just one week later, the company demonstrated the reactor generating electricity to power an Nvidia Blackwell system. Valar now says the new funding will help it move from proving its technology works to producing reactors at scale.

          The timing is no coincidence. AI’s enormous appetite for electricity is forcing the tech industry to confront a basic reality: the cloud still has to plug into something. Training models and operating massive data centers will require far more reliable power, and nuclear energy is rapidly becoming one of Silicon Valley’s favorite answers.

          Hadrian and Valar may be solving different problems, but their unusually large rounds point to the same shift. AI can design, predict and automate, but it cannot manufacture a missile component or generate a megawatt of electricity on its own. That requires factories, energy systems, supply chains and a great deal of capital.

          For years, venture-backed companies competed to build the software layer. Now, some of the biggest bets are being placed on the infrastructure underneath it.

          The future may run on AI. But first, someone has to build what keeps it running.
