XReal Estate Data, Virtual Homes and the Future of Proptech at dot.LA's Salon Event

On Tuesday evening, dot.LA hosted a Proptech Salon to create space and encourage proptech founders and investors to discuss how Southern California real estate startups are disrupting the industry. Over 70 invited guests gathered at WeWork's Century City location, including Michael Martin of Avenue 8, Nick Marino of TruLiv and Andrew Swerdloff of StayOpen.
The event kicked off with a conversation with JoyHub co-founder and CEO Elizabeth Braman, who announced the data aggregation and business intelligence platform will soon change its name to Revolution RE. Prior to starting JoyHub, Braman spent time at crowdfunding real estate platform Realty Mogul as senior managing director.
Braman said the inspiration for creating JoyHub came from the problems she saw in the real estate industry around the lack of data consistency and the overwhelming amount of data that real estate operators of apartments and rental properties have to make sense of. She saw a need for a tool that could simplify the data for real estate companies so they could use it effectively.
“I learned that legacy technology created a lot of problems," she said. "Proptech and all these new innovative solutions were compounding the problem by creating massive amounts of data silos.”

With any new venture or startup, there’s always a risk of it failing, she said:
“Anyone who tells you that starting a company during a pandemic is easy is not being truthful,” she said, adding that she was lucky that she was able to work with a team she already knew well from her first startup experience.
For much of the rest of the startup community, times are looking more challenging than they were not long ago.
“The high-gross C, D unicorn-type companies are having a very challenging time raising up rounds," dot LA Executive Chairman Spencer Rascoff said. "And A and B—not so great.”
Rascoff offered some advice to young companies hoping to weather the storm.
“Realistically, you should try to tighten your belt as much as possible to extend the runway as long as possible so that if you can't get a round done this year, you prioritize survival over growth," he said. "Because there'll be time for growth later.”
Another hot topic in proptech was virtual real estate. The concept of the metaverse has grown in popularity as new virtual environments go online. Celebrities like Snoop Dogg already own land in some of these new worlds. In December, one of his fans purchased a plot of land for $450,000 just to be the rapper-entrepreneur's virtual neighbor.

As an investor, Rascoff said he’s skeptical about buying land in the metaverse.
“The big reason why I'm overall skeptical of this is for some of these things, you need counties to play ball,” Rascoff said. “But it's fun and interesting to talk about how title might be disruptive through blockchain.”
The night was capped with a question from dot LA CEO Sam Adams:
“If given a million dollars to invest, where would that money go?”
Braman said she would have to diversify and choose cannabis along with venture funds.
Rascoff admitted his answer was less exciting, but said he'd would use the money to buy a “basket of growth tech stocks that are at two-to-five-year lows.”

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.

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.
