Sandbox Studios’ Jackie Fast on the New Ways Celebrities Are Partnering With Startups

Jackie Fast doesn’t think celebrities make good entrepreneurs. Instead, they make great assets for young companies.

On this episode of the LA Venture podcast, the Sandbox Studios managing partner discusses why many celebrities are exploring startups. Sandbox is a $30 million seed-stage fund that invests in brands that are being built by celebrities.


“The motivation for me is absolutely everything,” Fast said. “Why is this person doing this? Often—I mean, 100 times out of 100—it's not because they care. They want to make more money.”

Fast started her consultancy, Slingshot Sponsorships, at 24, after she was passed over for a role at the organization at which she was working.

“I was very qualified for the role. Even to this day, I still am annoyed about it. I applied and the CEO just said, ‘You're too young. You need more experience’.” She quit soon afterward and by 26, Fast signed Prince as her second client—without realizing that the iconic musician was notoriously uninterested in sponsorships.

“Prince was one of my first clients and—I didn't know this at the time—but the reason we got Prince was because nobody wanted to work with him to do commercial stuff. Because he didn't care. He's all about the music.”

Fast helped launch his album “20Ten” through Spotify and the DailyMail. It was the first time an album had launched on the growing music platform, and the move helped Prince quickly climb the charts.

“That just catapulted me into the music scene,” Fast said.

She took on clients including The Rolling Stones, Duran Duran and One Direction.

“My whole ethos was that social media and digital technology was changing and shaping the way that consumers and fans could engage with the things that they loved,” Fast said.

Slingshot prepared Fast to evaluate celebrity-backed companies and consider how their audiences can help a product thrive.

“A brand fundamentally is trying to ship product. So there are certain times when consumers are more receptive to information. And a lot of that is when they are enjoying themselves, they're having fun, they're in a calm place,” she said. “So any of those kind-of core emotional, humanistic things that connect people with other people—if a brand can insert themselves in the middle of that—that's where the recall comes from. That's where you start associating your own individuality with a brand.”

Celebrities began eyeing equity deals more seriously after George Clooney sold his tequila company, Casamigos, for $1 billion in 2017. Instead of promoting the brand for cash as most celebrities do, Clooney—one of its founders—opted for equity. When the brand eventually sold, he did well.

“When George basically did nothing and made a billion dollars, everybody was like, ‘Oh my goodness, we should be doing this. Why are we taking fees?,” Fast said.

The problem, she added, is that most talent agents make their money through commission and wouldn’t benefit from equity deals. Many of them ignored celebrities’ requests, leading frustrated talent to reach out to startups on their own—sometimes even using DMs to initiate contact. Often the resulting deals were not good ones, Fast said. Large talent agencies including CAA and WME have since set up venture arms for their clients.

Sandbox’s portfolio includes Kylie Cosmetics, Fabletics and Aviation Gin. The fund also invested in the animation studio Invisible Universe, alongside partners including Reddit co-founder and investor Alexis Ohanian. Invisible Universe partners with celebrities to create animated characters and build their following on social media. Once they gain traction, they can become the basis for books, shows, podcasts and other creative ventures.

“With these small animation companies, they can turn around ideas in a day and a half,” Fast said. “They create short form content that goes on Instagram Stories, TikTok [and] Reels, and they build momentum and following through lots of short-form content.”

While Fast invests in products built by celebrities, she said she views them less as entrepreneurs and more as a way for companies to gain instant brand recognition.

“I'm investing in a route-to-market and an asset that most companies don't have access to,” she said. “I don't look at the celebrity as like a person or a founder. I look at the celebrity as the marketing arm or the marketing special dust that you can add to a product.”

The Legal System Just Got Its AI Upgrade

🔦 Spotlight

Hello Los Angeles!

We talk a lot about AI in L.A., usually in the context of streaming platforms that “recommend” a movie you regret watching or apps that let you swap your face onto a Marvel poster. But the most interesting AI stories here aren’t gimmicks; they’re rewiring the hidden machinery of massive, slow moving industries. And this week, that spotlight falls on…lawyers.

LawPro.ai, a Los Angeles based legal tech startup, just closed a priced seed round led by Scopus Ventures to bring AI deeper into the world of injury claims. Their new “Case Assistant” isn’t about flashy automation, it’s about instantly surfacing case insights, cutting down endless hours of drafting, and helping law firms run with the precision of a Formula 1 pit crew.

Here’s why this matters: the legal industry has been one of the last holdouts when it comes to adopting tech that actually speeds things up. Now, with AI making its way from the red carpet to the courtroom, we’re watching the early stages of a shift that could change how justice is delivered in real time. In L.A., we’ve already seen AI startups shaking up entertainment, aerospace, and healthcare. Legal might be next.

And if LawPro.ai pulls it off, you might not just get a faster verdict, you might see the ripple effect across an industry that has spent decades charging by the hour. In other words, the billable clock might finally start running in our favor.

                  Locket, Disney, Instagram and the Battle for Your Attention

                  🔦 Spotlight

                  Happy Friday, Los Angeles!

                  This week, LA’s biggest tech and media players made one thing clear: they want to own the relationship. Whether it’s a celebrity sending selfies straight to your home screen or a content giant rewriting the rules of sports broadcasting, the power shift toward more curated, direct experiences is unmistakable, and it’s being engineered right here.

                  Image Source : Locket

                  📸 Locket Doubles Down on Star Power

                  Venice-based Locket, the viral photo sharing app that made homescreen widgets cool, is now leaning into what LA does best: celebrity. Its new feature, Celebrity Lockets, allows artists to send exclusive photos directly to fans’ home screens. Early adopters include Suki Waterhouse and JVKE, with creators curating limited fan access to maintain intimacy and exclusivity. As Locket evolves from a casual social tool into a direct fan engagement platform, it’s becoming an increasingly relevant player in LA’s creator tech ecosystem.

                  🏈 Disney’s ESPN Plays Offense

                  Disney made a trio of bold moves this week that solidify ESPN’s future and its dominance in sports media. It’s buying out the NFL’s stake in ESPN, securing exclusive NFL Draft and behind the scenes content through 2033, and finally giving its standalone ESPN streaming service a launch date: August 21, 2025. That’s a power play straight out of Burbank. At the same time, Disney announced it will no longer report individual subscriber numbers for Disney Plus and Hulu, signaling a shift in how it wants investors and maybe consumers to measure success.

                  🗞️ The New York Post Bets on LA

                  In a sign of LA’s growing national influence not just in entertainment, but in news, the New York Post is launching a West Coast vertical called The California Post. With an editorial mission to cover the state’s cultural and political pulse, this move reflects a broader trend of major media brands planting roots in LA to chase both readers and relevance. For local media startups, content creators, and civic tech players, it’s yet another sign that the competition and the opportunity is growing.

                  📱 Instagram Wants Your Inner Circle

                  Instagram rolled out a new set of features this week that prioritize connection with close friends. Users can now share what they’re doing, watching, or feeling with a smaller group, clearly borrowing from the intimacy playbooks of apps like BeReal, Snapchat, and yes, Locket. As social platforms shift from mass broadcast to curated circles, LA-based creators and consumer startups should take note: the next frontier might not be going viral, it might be going personal.

                  From star-powered lockets to streaming shakeups and platform reinventions, this week’s stories highlight how LA’s tech and media companies are rewriting the rules on connection and control.

                            Smart Shoes for Kids? Skechers Thinks So 👟

                            🔦 Spotlight

                            Happy Friday, LA!

                            This week, Skechers may have just kicked off a new trend that’s bound to have parents and tech lovers talking. They've unveiled the "Find My Skechers" line, kids’ sneakers that come with a hidden compartment to securely hold an Apple AirTag. For $52 to $58, parents can now track their child’s shoes in real-time using the Find My app, giving a whole new meaning to "keeping an eye on things." While these tech-savvy kicks are already gaining attention, will they become the new norm in kids' footwear? And who’s next? Will Nike or Adidas be jumping on the AirTag bandwagon, or is Skechers setting the stage for a whole new wave of tech-integrated fashion?

                            But it’s not all smooth sailing. This innovation raises some interesting questions about privacy and surveillance. Are we crossing a line when we start tracking our kids’ every move through their shoes? While Apple’s anti-stalking features are in place to prevent misuse, it will be intriguing to see how other brands and parents respond to this new blend of fashion and tech.

                            What do you think? Could this become a must-have feature in the next generation of kids' gear, or is it a step too far? Let us know your thoughts!
