Taking their lead from social media entrepreneurs who are creating content from mansions, a new breed of startup incubators and collectives are cropping up across Los Angeles. Their programs were built largely by young entrepreneurs trying to bridge the creator and startup worlds, speak to a generation that has grown up alongside social media.


Some are inspired by other co-living incubators or from founders who wanted to capture the creative energy those houses spawned.

In the Hollywood Hills, a collective started by two twenty-seven year-old entrepreneurs is helping seed-stage companies land funds and build up their products. Across town, a roving launch house focuses on building biotech entrepreneurs. Another is trying to foster breakthrough products in augmented reality.

Here's a run down of some of the most promising co-living concepts, along with their founders and the projects they're incubating.

Launch House

Launch House formed last year after one of its founders tweeted about an experimental gathering of entrepreneurs in Tulum, Mexico. Located in a sprawling Beverly Hills mansion, the hub puts a heavy emphasis on social media and influencer-driven business ideas and runs monthly cohorts of about 20 founders each, connecting them with creators to build up their social media game. Potential participants must apply and then pay an annual membership fee, which includes the four-week live-in residency program and access and introduction to investors and advisors. Participants have to be 18 years of age or older.

"Many creators want access to startup investing opportunities but either don't have a way into top deals, or get pitched so often they can't easily decipher what's a good investment," said co-founder Brett Goldstein, "On the reverse side of things, many founders see collaborating with creators as a great way to reach new target audiences because distribution is a hugely scarce resource."

Several Launch House residents have gone on to raise successful rounds from staid investors including Sequoia and Y Combinator, though a Business Insider report about a COVID outbreak after a recent party raised questions about the culture at the home.

Brazen Bio

Started by longtime friends Shawn Carbonell and Brent Witgen, Brazen Bio is a biotech incubator house based in Redondo Beach which also provides members with lab access to Bio Labs in Torrance.

Inspired by other launch houses, the two PhDs wanted to create the first biotech hub in Los Angeles that combines the region's creator economy with its budding scientists and entrepreneurs.

"Part of our goal is to make it one of the top biotech hubs through us being here. As BioscienceLA Chief Executive Officer Dave Whelan would say, 'we're long L.A.'," said Carbonell, "Most companies need to also become media companies to stay relevant, and where better than Los Angeles for that?"

Four startups were accepted in the first round of what Brazen Bio is calling its 'BRZN1 cohort. The program started last month and runs through December. It's replete with a full line up of founder dinners and mixers, access to Bio Labs' equipment and weekly office hours. The founders aren't yet making seed investments but will be establishing a fund for 2022.

Carbonell said they are trying to find ways to promote Brazen through Discord and social media to Gen-Z entrepreneurs and encourage a new generation to enter the STEM field.

house.ai

The 27-year-old co-founders Robbie Figueroa and Luciano Arango moved from the Bay Area to Los Angeles, where they saw a maturing tech scene they thought could be a good place to build startups. The two convinced their tech friends to make the trip down to the Hollywood Hills, where they created a collective and early-stage fund called House.ai.

House.ai doesn't offer a full-time residency like Launch House. Instead, it sees itself as a place where founders can gather to co-work. Figueroa, a general manager for DoorDash in Puerto Rico, and Arango, a co-founder of San Francisco-based ScopeAI, both live in the house. There's no formal application for House.ai — instead, Arango and Figuero select premiere founders and operators to join them.

In the past year, House.ai has provided co-working space for 37 founders. The program connects them with early-stage venture capital and helps them recruit talent and connect to engineers. Figuero and Arango have so far invested in six of the companies — including cannabis wholesaler Nabis, a Y-Combinator-backed company.

Figuero considers House.Ai an industry-agnostic incubator, though its startups tend to gravitate towards fintech, fulfillment and delivery services, along with some consumer and business-to-business companies.

AR House logo

AR House

The AR House was born out of a tweet from augmented reality developer Aidan Wolf: "anyone organizing a house for snapchat lens creators? Would love to do something like that here in LA."

The response was overwhelming. Among those who reached out was AR creator Lucas Rizzotto.

The team quickly coalesced around the idea of a house dedicated specifically to AR creators and developers. L.A., home to AR juggernaut Snapchat, had more than enough talent. Within a week, the two had met their funding goal, much of it coming from the AR community.

Creators must be 18 years old or older to apply. AR House's founders don't take equity in the companies they help launch, but they do help provide participants with AR hardware to support their projects.

The cohorts will have access to a four-week session complete with dinners for founders, meet-and-greets with investors and other programming. The house doubles as an exhibition space for augmented reality projects, too. AR's first cohort started on October 5 and they signed a six-month lease to their Hollywood Hills house.

Rocketship House

Bay Area native and consumer tech founder Katia Ameri and YouTuber Elijah Daniel bootstrapped Rocketship House in November 2020. The house, based in the Hollywood Hills, boasts a stunning view of Los Angeles and an acre-long vineyard where participants are encouraged to collaboratively contribute to projects focused on the creator economy.

Ameri brings a hard-tech background. She raised $2.2 million for her telehealth platform, Mirra, an at-home allergy diagnosis service, before the pandemic started. Daniel brings social media savvy and a knack for making viral videos. The two say they are focused on projects that help creators develop content distribution and revenue streams.

Rocketship's residents have included musician Trevi Moran, musical artist and YouTuber Sam F and nicotine company Lucy co-founder Samy Hamdouche, whose startup is backed by Y-Combinator.

Daniel and Ameri aren't interested in taking equity. Instead, the pair said the want to focus on building a community of creators and tech entrepreneurs. There's no formal application, though interested founders and creators can reach out to Ameri via Twitter to join. The two say they are flexible about how long creators or founders can stay in the house. After experimenting with co-living, Rocketship House's founders said they're pivoting toward a model that will instead seek to foster a digital community and provide a physical workspace.

ADVNTR House

Advntr House was created by the co-founders of a college party app Dive.Chat, Michelle Fang and Kyle Brastrom. Its Gen-Z cohorts have served as founders of a wide variety of consumer, healthcare, fintech and media startups.

"A majority of the people that have entered ADVNTR House have either quit their full-time job, ended a relationship of over a year or dropped out of college," Brastrom said, "People kind of come into the house and then realize 'wow, there's so much opportunity out there'."

Participants live in ADVNTR's Melrose home, but the group also travels to destinations like Big Bear, California and Arizona. Every cohort shares the expenses and collectively develops the group's activities. There's a formal application and interview process to join ADVNTR. The cohort program lasts about eight weeks.

Fang and Brastrom organized L.A. Tech Week, a collaboration with other tech houses including House.ai, Launch House and Together Casa, a real estate startup organizes co-living houses for tech entrepreneurs, creators and other interest-focused communities.

AI Dominates the Headlines, but Defense Tech Is Gaining Speed

🔦 Spotlight

Hello, Los Angeles!

This week, DeepSeekAI has been dominating the tech conversation. The Chinese AI startup’s chatbot app surged to the No. 1 spot on the App Store, drawing both excitement and scrutiny. Supporters see its open-weight model as a potential game-changer, offering developers more flexibility compared to closed AI systems like OpenAI’s. But the rapid rise has also raised questions about security, data governance, and global AI competition. Whether DeepSeek will be a long-term disruptor or just a momentary sensation remains to be seen, but one thing is clear—AI remains the tech industry’s driving force.

But while AI continues to dominate headlines, another sector is quietly making waves—defense technology. And one LA-based startup just secured a major endorsement from investors and the U.S. government.

Castelion’s Hypersonic Bet—Can It Outrun the Defense Industry’s Red Tape?

Image Source: Castelion

El Segundo-based Castelionjust raised$100 million to accelerate its mission to build hypersonic weapons faster, cheaper, and at scale. The financing—$70 million in equity (led by Lightspeed Venture Partners with participation from a16z, Lavrock Ventures, Cantos, First In, BlueYard Capital, and Interlagos) and $30 million in venture debt (from Silicon Valley Bank)—is the latest sign that venture capital sees national security startups as a high-growth opportunity.

Unlike traditional defense contractors, Castelion is operating like a fast-moving startup, not a slow-moving government supplier. Founded by former SpaceX engineers, the company is applying an iterative, test-heavy approach to building long-range hypersonic strike weapons—which travel at speeds exceeding Mach 5 (3,800+ mph) and are designed to evade modern missile defenses.

Not Just VC-Backed—The U.S. Military is Betting on Castelion Too

While the $100 million raise is a major milestone, Castelion already has funded contracts with the U.S. Navy, U.S. Air Force, and U.S. Army. These contracts are focused on hypersonic technology development and scaled manufacturing, areas where the military has struggled to move quickly due to bureaucratic delays and reliance on traditional defense giants.

To prove it can execute, Castelion recently successfully launched a low-cost ballistic missile from a self-built launcher in Mojave. Now, with both government contracts and venture capital behind it, the company is pushing forward on more flight tests and building out its scaled production capabilities.

With rising geopolitical tensions and an increasing focus on faster, cost-effective deterrence, Castelion is positioning itself as a new kind of defense player—one that moves at startup speed. Whether it can sustain that pace while navigating the complexities of government procurement remains to be seen, but one thing is clear: the future of defense tech isn’t just about who can build the best weapons—it’s about who can build them fast enough.

      Can Technology Outpace Wildfires?

      🔦 Spotlight

      Hello, LA!

      This week, tech headlines are buzzing with OpenAI's launch of Operator, a tool that promises to transform task automation, and TikTok’s major outage, which left millions disconnected. But closer to home, as wildfires blaze across Southern California, survival has become the focus—and technology is making it possible.

      When the plume of smoke reappeared on the horizon, residents across Southern California turned to tools like Watch Duty. Over the past week, as flames surged, the app gained 600,000 new users in just one night, delivering critical, real-time information to help residents stay ahead of danger. Watch Duty, designed to provide wildfire updates, has proven to be much more than an alert system. It’s a lifeline.

      The New Face of Live Shopping: Whatnot’s $5B Journey

      🔦 Spotlight

      Hello Los Angeles,

      This week has been a challenging one for many in our city as we continue to face the aftermath of the recent wildfires. Recovery efforts are in full swing, and as always, the strength and resilience of our community shine through.

      If you or someone you know has been impacted, there are resources available to help navigate this difficult time:

      • Pacific Palisades Fire Damage Maps: View here

      These tools can provide support, whether you’re looking for financial assistance, housing resources, or updates on affected areas.

      While our community focuses on recovery, we’re also reminded of what makes LA unique: its unrelenting drive to build, create, and innovate. A great example this week comes from Whatnot, the live shopping platform co-founded in 2019 by Grant LaFontaine and Logan Head, which has just achieved a major milestone.

      Whatnot announced it raised $265 million in Series E funding, valuing the company at an impressive $5 billion.

      For those unfamiliar, Whatnot combines shopping and entertainment through live-streamed auctions. Think of it as a vibrant, interactive marketplace where sellers showcase everything from trading cards and collectibles to fashion items, all in real time. Buyers can bid during the stream, creating a sense of excitement and connection that feels more personal than traditional online shopping.

      The company’s new funding—co-led by Greycroft, DST Global, and Avra Capital—will drive expansion into markets like Australia and bring improvements to seller tools, from inventory management to advanced analytics. But what stands out most is Whatnot’s focus on its people. CEO Grant LaFontaine announced plans to buy back $72 million in shares for long-term employees, a move that underscores the company’s dedication to sharing its success.

      As we move forward, let’s celebrate stories like these that show how innovation thrives in LA—even amid challenges. Whether it’s supporting wildfire recovery, building the next great startup, or simply connecting with others, we each play a role in shaping the spirit of our city.
