How Nonprofit Closegap Aims to Create Mental Health ‘Guardian Angels’ in LA Schools

She was a Livingston Award finalist in 2011 and holds a Master's degree in journalism from Boston University and BA from the University of Windsor in Ontario, Canada.

Classroom using Closegap

Rachel Miller, founder and CEO of Closegap, has always been interested in helping kids who did not win the "birth lottery," as she calls it.

She is one of them.


Growing up, her mother had schizoaffective disorder, but did not take medication for it. Miller often stayed at strangers' houses or with family and friends because her mother had a hard time keeping a job. As a result, she often found herself exposed to others who were using drugs.

One night when she was 9, Miller thought she would have to sleep on the streets, but she and her mother received a last-minute motel voucher after standing outside a welfare office for hours.

It was in education that Miller found refuge. She'd often bounce around to several different schools in a year, but often was surrounded by teachers she saw as "guardian angels" who cared about her and her situation.

The support propelled her to attend Los Angeles Pierce College and then USC's Marshall School of Business before getting a master's degree in entrepreneurship at the University of Amsterdam. Drawing on an entrepreneurial spirit, she started a donation platform where people could gift specific items to disadvantaged families. It ultimately failed but something else bloomed.

"I learned so much and actually realized that I don't want to try to eliminate the adversity that kids experience," she said. "I want to optimize the support that they get from the adults around them and teach them the coping skills they need."

Student using Closegap

She launched Closegap in 2019. The web-based app used by schools lets students check in daily with their emotional well-being by answering questions like: Are you feeling worried or are you feeling like you are worth less than others. The questions are tailored to different age groups and teachers and counselors get results for each student. It tells them whether a child hasn't had breakfast that morning or is experiencing suicidal ideations.

For years, Miller was reluctant to share her story. She had a difficult childhood, one that she often didn't feel comfortable talking about. But she came to understand that it was that pain where her passion for disadvantaged kids comes from.

About 2,100 schools across the U.S. use the Los Angeles-based nonprofit's app, as well as schools in 25 countries. Students have completed about 2.5 million "check-ins."

When COVID hit, the app went from reaching 10,000 students to 140,000 students in two months, Miller said. That number has now reached about 160,000 students.

It's no coincidence. The American Psychological Association's Stress in America 2020 study shows that 43% of Gen Z teens, aged 13 to 17, say the level of stress in their life has increased over the past year. And a UNICEF report on the mental health of children globally found that 1 in 7 adolescents is estimated to live with a diagnosed mental disorder.

School districts across the country, and here in Los Angeles, are hiring school psychologists and psychiatric social workers to address the need.

Closegap targets schools because that's where Miller thought it would be most effective. "Not all families are created equal," she said. Community resources often fall short. She thought Closegap could help students make a connection with at least one adult.

"If we can optimize for that, if every kid had at least one trusted adult, our entire society would look different, that would literally change everything," she said. "That's why Closegap really focuses on that check in and getting them in contact with school counselors and teachers," Miller said.

The app has a free version that's more focused on the connection with an individual student as well as a recently launched paid premium product that provides aggregated data to school districts.

"The idea is to create a safe digital space, where they feel comfy sharing, so it's not just a survey," she said. "It's really this moment where you get to check in with your emotions, your somatic sensations, your energy level and then you get to share if you have any challenges."

There are then activities on the app that students can do if they choose, like deep breathing exercises, progressive muscle relaxation and therapeutic shaking.

When it comes to student data privacy, Miller said it's something she takes seriously and part of the reason she founded the organization as a nonprofit.

So far, the only time Closegap will intervene is when a student reports ideas of self-harm or suicide. They will follow-up with the school to ensure an adult has been in contact with that student. She said all of the students who have reported self-harm or suicide on the app are receiving treatment.

Miller has relied on philanthropic donations to fund the app so far. She has several investors, rather than a single one -- much like a startup backed by venture capitalists would have.

The company is now working on integrating pieces into the app that orient children to the future, rather than living in the here and now. Students who experience trauma are often stuck in their present situation, in survival mode, she said.

"What I want to work on next is really making sure that all students, regardless of the circumstances they find themselves in, have some concept of the future and can start to at least a little bit visualize what their lives might look like after whatever it is they're in," Miller said.

An LA AI Company Just Won Entertainment’s Backing

🔦 Spotlight

Hello LA.

The entertainment industry has spent the past several years debating what generative AI could take from creators.

This week, some of its biggest companies put money behind an AI startup promising to build something for them instead.

Los Angeles-based Stability AI raised $76M in Series B funding from an investor group that includes Electronic Arts, Sony Music Group, Universal Music Group and Warner Music Group. AMD Ventures and Pacific Alliance Ventures also joined the round, while LA-based MANTIS Capital and Sound Ventures are among the company’s existing backers.

The financing brings Stability AI’s total funding under CEO Prem Akkaraju to $232M, including two equity rounds and convertible notes. The company plans to use the new capital to expand its creative production tools, applied research and professional services across music, gaming and entertainment.

The amount is notable. The names attached to it are the bigger story.

Generative AI’s arrival in entertainment has been anything but quiet. Artists have questioned whether their work was used to train models without permission. Studios have faced pressure over how the technology could affect jobs. Record labels have pursued AI companies in court while simultaneously exploring how the same technology might fit into their businesses.

Now, several of the world’s largest entertainment companies are investing directly in one.

That does not mean the industry has resolved its concerns about AI. It means some of its biggest players would rather help shape the technology than wait to see what it becomes.

Stability AI is positioning itself for that opening. Rather than focusing solely on general-purpose models, the company is building tools specifically for professional creatives. Its recently launched Stable Audio 3.0 was trained on fully licensed music and lets artists generate, edit and arrange audio through a web platform or directly inside digital audio workstations.

That licensed-data approach is central to the pitch. The next phase of creative AI will not be decided only by which company produces the most impressive model. It will also depend on which companies can earn the trust of the artists, studios and rights holders whose work gives those models value.

For its new strategic investors, the round offers more than financial upside. It creates a closer view into how generative AI may change production, a voice in how the tools develop and an opportunity to establish rules before those rules are established for them.

For Stability AI, the backing provides something equally important: credibility inside industries that have every reason to scrutinize what it is building.

The company now has capital and access to some of the largest catalogs, franchises and creative workforces in entertainment. What it does with that access will determine whether this becomes a meaningful alliance or simply an impressive collection of logos.

Either way, the industry is no longer watching from a safe distance.

It has entered the room.

LA’s Air-Taxi Plans Are Coming Downtown

While Stability AI is trying to change how entertainment gets made, Archer Aviation wants to change how people get to it.

AEG and Archer announced plans to develop downtown Los Angeles’ first vertiport at L.A. LIVE, creating a potential new stop in Archer’s proposed electric air-taxi network ahead of the 2028 Olympic and Paralympic Games.

Image Source: Archer

The planned site would sit beside Crypto.com Arena and allow passengers to travel to and from the entertainment district aboard Archer’s Midnight aircraft. The company says its network could turn drives that take an hour or longer into electric flights lasting approximately 10 to 20 minutes.

Archer has already identified SoFi Stadium, USC and Hollywood Burbank Airport as possible locations, with its recently acquired Hawthorne Airport expected to serve as the network’s central operating hub. As the official air-taxi provider of LA28 and Team USA, Archer has an unusually visible deadline for turning those plans into something tangible.

AEG and Archer have completed an initial feasibility study of the L.A. LIVE site, including reviews of land use, airspace, power availability and community impact. The next phase will examine operations and the passenger experience.

There is still a substantial distance between a proposed vertiport and a functioning air-taxi network. The infrastructure must be built, regulatory approvals must be secured and passengers must be persuaded that flying across the city is safer and more practical than staying on the ground.

Still, few locations could make that future feel more real than L.A. LIVE. Millions of people already pass through the district for concerts, games and major events. Placing a vertiport there would bring urban air mobility out of the concept stage and directly into public view.

Together, this week’s announcements show Los Angeles becoming a testing ground for two technologies still moving from promise toward everyday use.

One could reshape how entertainment is created. The other could reshape how Angelenos reach it.

In a city famous for both its creative industries and its traffic, that feels appropriately on brand.

      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.
