Techstars' Space Accelerator took off this week with its third class of space-related companies that make everything from AI-powered smart cameras to technology that can anticipate celestial collisions.
The 10 startups selected for the competitive four-month program are based across the U.S. and Australia and will work with Techstars on a mostly remote basis.
All are developing technology with multiple uses in space and will receive a $120,000 investment in addition to access to Techstars' expanding network of mentors.
That network includes aerospace experts at the Pasadena-based NASA Jet Propulsion Laboratory. Participating companies include Lockheed Martin, Arrow Electronics, SAIC and Israel Aerospace Industries.
"Alumni from our previous cohorts are launching space systems and infrastructure, raising tens of millions of dollars in venture capital as well as receiving lucrative contracts from both government and commercial customers," said Jonathan Fentzke, the program's managing director.
The program will culminate in a demo day on Sept. 2 where the startups will show off their work in hopes of winning potential investors or clients.
Fentzke noted that while no companies in this year's cohort are based in LA, Techstars still has partners mentors and investors based here.
"As it turns out the four companies in California out of 10 are not based in L.A. today, but will likely have a presence over time," Fentzke told dot.LA.
Here's a look at the 10 companies selected for this year's Techstars Space Accelerator.
Hyperkelp
LOCATION: San Clemente, Ca.
CEO: Graeme Rae
Founded by maritime engineer Dr. Graeme Rae, Hyperkelp is building buoys that aren't your average fishing bobber. Its tech can collect and transmit data about the surrounding ocean and incoming payloads from space. The company says its goal is to create a network of the buoys around the ocean to help aerospace launch companies stream data from anywhere around the world.
Hyperspec.ai
LOCATION: San Francisco, CA. and Tel Aviv, Israel
CEO: Ohad Levi
Hyperspec.ai makes smart cameras that run on artificial intelligence. The company's CEO Sravan Puttagunta previously worked in HP's engineering department. In a nutshell, Hyperspec's cameras are made to create accurate mapping and object tracking in real time, with the goal of being used on self-driving cars and other autonomous vehicles.
Nicslab
LOCATION: Sydney, Australia
CEO: Dr. Andri Mahendra
Nicslab develops technology called the "source measurement system" that uses quantum computing to help organizations optimize their internet speeds and make them faster. Its current clients include the University of Oxford, HP Labs and Mitsubishi Electric.
Pierce Aerospace
LOCATION: Indianapolis, In.
CEO: Aaron Pierce
Pierce Aerospace makes software that helps autonomous drones identify objects and payloads. It argues that this software is critical to the development of the drone industry -- after all, it can be pretty scary if a drone goes rogue because it can't see where it's going. In 2019 the company received a roughly $50,000 grant from the U.S. Department of Defense to continue work on its flagship product, the Flight Portal ID system, which the DoD wants to use on its Unmanned Aircraft Systems.
Pixspan
LOCATION: Rockville, MD.
CEO: Michael Rowny
Pixspan develops a system that lets large files be transferred from different storage locations (like hardware or the cloud) at rapid speeds -- sometimes up to 5 times faster than average, it reports. It's compatible with several app programming interfaces, the main one being Amazon Web Services.
QuSecure
LOCATION: San Mateo, Ca.
CEO: Dave Krauthamer
QuSecure is a security company that focuses on protecting government and corporate systems from hacks. Specifically, its software works to keep encrypted data from being stolen and decrypted by quantum computers, which can steal and read valuable information at rapid speed. Its customers include Google and Amazon.
SCOUT
LOCATION: Alexandria, Va.
CEO: Eric Ingram
Scout -- also known as Scout Space -- develops software that helps spacefaring companies visualize what's going on in the great beyond and avoid casualties, like crashes with other spacecraft, satellites or debris. The company was founded in 2019 and says its name is an acronym for helping Spacecraft Observe and Understand Things around them.
SeaSatellites
LOCATION: San Diego, CA.
CEO: Mike Flanigan
As the name suggests, SeaSatellites is building unmanned vessels that work as satellites for the ocean and have a wide array of potential uses, from environmental data collection to communications. Similar to their skyward counterparts, SeaSatellites' tech can be controlled from anywhere and are designed to carry payloads on long missions.
Xairos
LOCATION: Denver, CO.
CEO: David Mitlyng
This company's name is Greek to us -- literally. A nod to the Greek god of opportune time, Kairos, is an appropriate name for this startup using quantum mechanics to bring GPS-type technology to areas of the globe without internet access.
Thermexit
LOCATION: Boston, MA.
CEO: Katie Willgoos
Thermexit is the only company in this year's Space Accelerator cohort that's led by a woman. CEO Katie Willgoos joined the company in March and helps the company create and sell its main product, Theremexit Pads, which are tiny thermal sensing sticky pads that can be placed on circuit boards and inside computers.
Correction: An earlier version of this post stated this is Techstars' second space accelerator cohort. It's the accelerator's third such class. It also, misnamed the CEO of Hyperspec.ai.

Hey there, Los Angeles.
For the past decade, Alex Heath has made a career out of figuring out what the technology industry is doing before everyone else.
Now, he is going to invest in it.
Heath announced this week that he is joining Los Angeles-based Sound Ventures as a partner on its investing team. The veteran technology journalist will continue independently operating Sources, the newsletter and podcast business he launched after leaving The Verge last year.
It is an unusual career move, but perhaps not as unusual as it initially appears.
Journalists and venture capitalists spend much of their time doing surprisingly similar work. Both look for signals before they become obvious, build relationships with people who know what is coming next and attempt to distinguish a lasting shift from a convincing story.
The crucial difference is what happens after they find one.
A journalist publishes. An investor writes a check.
Heath has spent years reporting on some of the technology industry’s most powerful companies and executives. At The Verge, where he served as deputy editor, his work focused on the internal decisions shaping companies such as Meta. More recently, Sources has taken readers inside the AI race through reporting and interviews with executives including Sam Altman and Mark Zuckerberg.
That experience gives Sound something venture firms increasingly want: someone who already understands the founders, companies and narratives competing to define the next era of technology.
Sound Ventures is not exactly starting from scratch. Led in Los Angeles by Guy Oseary and Effie Epstein, the firm manages nearly $2B and has backed companies including OpenAI, Anthropic, World Labs, Brex, Affirm and GitLab. According to The Wall Street Journal, Sound deployed more than $800M into early positions in OpenAI, Anthropic and World Labs as it intensified its focus on artificial intelligence.
Heath is joining during an important transition for the firm. Ashton Kutcher, who co-founded Sound with Oseary in 2015, departed earlier this year to launch a new venture firm. Oseary and Epstein are continuing to lead Sound while raising its fifth flagship fund and sharpening its strategy around companies with the potential to reach meaningful commercial scale.
Adding Heath suggests that Sound’s next phase will not be defined by capital alone.
As AI makes it faster and less expensive to build software, technical capability may become less effective as a differentiator. More startups will be able to create credible products, and more of them will compete for the same finite supply of customers, talent and attention.
In that environment, knowing how to identify a compelling founder is only part of the job. Venture firms also need to understand how companies earn trust, communicate what makes them different and remain culturally relevant in an increasingly crowded market.
That is familiar territory for Sound. Oseary built his career managing artists including Madonna and the Red Hot Chili Peppers, where recognizing talent was inseparable from helping that talent connect with an audience. Heath brings a different version of the same instinct, developed through finding important stories and understanding why people should pay attention to them.
Heath will continue owning and operating Sources independently while expanding its podcast and interviewing prominent voices across the technology industry. That means he is not abandoning the platform or audience he built. He is adding a new vantage point.
The combination could prove especially valuable to Sound. Heath brings the instincts of a reporter, the reach of an independent media founder and years of relationships with the people shaping technology. Now, he can apply that experience to finding and supporting the next generation of founders.
It is a fitting evolution for someone who has spent his career identifying important technology stories early.
This time, he will have the opportunity to help write what happens next.
Venture firms once competed primarily through capital, networks and operating expertise. Now, access to attention is becoming an asset of its own. Founders need help reaching customers and shaping public understanding, while investors want better ways to recognize which people and ideas will command that attention next.
Sound Ventures hired someone who has spent a decade doing exactly that.
Heath used to decide which technology stories were worth following.
Now, he will help decide which ones get funded.

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.

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.
