“THE MAP”

*As of September 29, 2025*

This SoCal hard tech landscape map includes 226 hard tech companies across the region. As a reminder, I don’t include the Primes of the world in this map. These are mostly VC-backed startups, founded after 2000, with the majority launched in just the last seven years. SpaceX, founded in 2002, is one of the oldest on the list. The “SpaceX Effect” is evident, with roughly half of these companies tracing their roots back to it.

Looking at this map in comparison to my earlier versions, one thing remains clear:

Hard tech in SoCal isn’t confined to a single neighborhood.

While a few cities dominate, the density of startups across the region reveals just how extensive the ecosystem is.

A quick breakdown:

  • El Segundo leads the pack with 53 companies, making it the region’s undisputed hard tech capital.

  • Long Beach (21), Torrance (21), Hawthorne (16), and Los Angeles (13) round out the top five hotspots.

  • Mid-sized clusters include Pasadena (8), Irvine (8), Huntington Beach (8), San Diego (7), and Culver City (7).

  • Dozens of other cities have 1–5 companies, showing just how spread out SoCal’s ecosystem is.

Here’s how the above looks in a pie chart:

The South Bay continues to attract hard tech companies.

REAL ESTATE CORNER

Today, the Cambridge, MA-based company is announcing another $20 million round of financing that it’s labeling a Series A Plus. Led by Munich Re Ventures, with additional investment by Breakthrough Energy Ventures and DCVC, the Series A Plus designation is meant to indicate that this financing round comes with a different valuation and investment size than the Series A round—but the raise is not big enough to warrant a Series B designation, says Arvin Ganesan, CEO of Fourth Power. The additional $20 million, which brings the company’s total funding to $40 million, will be used to achieve commercial viability and build out a sales and partnerships pipeline. Fourth Power has developed a battery that can transform electricity into heat, store it in carbon blocks that become extremely hot, and then convert that heat back into electricity when needed via thermophotovoltaic cells.

WHAT I’M CONSUMING (AND ENJOYING!) 

Where is the VC money flowing in SoCal? (source: Stifel Bank)

📊 Stifel’s Greg Singer shares some thoughts and insights on his four years serving the SoCal VC world, including the growing momentum of hard tech (see above graph).

🎖 “The future of military power will not be determined by the most exquisite hardware, but by the most effectively scaled and networked family of capabilities.” Matthew Steckman, President and Chief Business Officer at Anduril Industries, and Eliot Pence, Founder of Dominion Dynamics, share their outline on some institutional principles for what a revolution in attritable mass will mean—for investors, Department of War officials, industry, and others.

🤖 “A robot is not a body type. A robot is autonomy wrapped in hardware.” Another banger from Henry Kwan’s Substack as he tells us how software will continue to eat the world (and the Stratosphere).

HOW I CAN HELP YOU

Some people only know me as “that Space Dirt newsletter guy.” Although I love that moniker, here are 3* ways I can help with your hard tech real estate when the time is right.

  1. A new home for your growing business. The good news - you’re growing! The bad news - you need to move, and you don’t know the hard tech real estate market. I can help. And I come with strong references.

  2. Sublease your space. You’ve outgrown your space and need to move, but don’t want to pay two rents? I got you.

  3. Time to renew your lease? Want to make sure you’re getting a fair deal from your Landlord? In my experience, you can never be too sure. (BTW, I recommend starting the lease renewal process 12 months out at a minimum.)

*Not an exhaustive list 💪

Thanks for reading.

If you’d like your office and/or manufacturing space or business profiled - or even your city! - let me know. It’s always fun to explore and share the different components of the hard tech industry.
