LeGrand Crewse has been biking for his entire life — but it wasn’t until he made his own bike that he knew he would “change the world.”


On this episode of the PCH Driven podcast, Super73 founder LeGrand Crewse talks about his journey from enthusiast and hobbyist to founding and electric, fat-tire motorbike company based in Orange County.

“My very first memory of what I’d call freedom was actually on my fifth birthday,” Crewse says. Why? “I got my very first bike.”

That He-Man bike with a three speed shifter is “all he wanted,” Crewse says. The bike let him explore his hometown in Arizona on his own and introduced him to biking, which he continued as a teen and into adulthood — until he got his first car. Then, he says, the bike went into the garage and he became fascinated with customizing his new gas-powered ride.

“[It’s] a little bit cringeworthy now, but I put this, you know, loud exhaust on it and spray painted the wheels and spent way too much money at Autozone on various little pieces,” he says.

It was his corporate job—and its miserable 17-mile commute—that would later match his flair for customization with his earlier love for bikes and inspire him to build his first electric vehicle

“I thought, ‘hey, well, maybe I'll ride my bike to and from work’. That only happened a few times— and I realized ‘this is not fun’, you know, especially at the end of the day—riding an hour and a half back,” he says “Eventually, that's kind of what led me to saying, hey, what if I put a motor on one of these things, and let's see what happens.”

By trial and error, Crewse taught himself how to convert his bike into an ebike over the course of months. He continued tinkering with it, adding different motors, power controllers and batteries. Eventually, he turned his bike into a vehicle that could get him to and from the office in comfort.

“It literally changed my life. Because at that point, you know, that commute went from being this horrible thing in the beginning of my day — and the end of the day, too. It was the thing that brought me joy, it was what I woke up and was looking forward to was the ride to work the ride back, because I didn't have to take the same roads that I normally did,” says Crewse, “And so just going through and not dealing with traffic and cars and all that frustration, it was everything… It completely changed my life and that I was so excited about this.”

At the time he began working on his first creation, Crewse was also starting grad school. To everyone who knew him at the office and in class, he was “definitely that annoying ebike guy.”

He says he showed off his custom ebike to everyone, and spent the next five years trying to create prototypes and monetize his creations. He began to work with small manufacturers to convert their bikes into electric bikes. During that time he developed a drive system and a process that could easily convert a regular bicycle into an electric bicycle.

“And so that became my niche.”

An old friend’s Facebook post inviting Crewse to join him on a vacation in China later became the catalyst for his own bike company. While there, Crewse met with electric motor manufacturers and suppliers, visited factories and learned about the Chinese railway system. He used the knowledge and network he developed in China to grow his business. Along the way, he met Aaron Wong and Michael Cannavo, who would later become his two co-founders.

The two had been trying to manufacture and market cargo scooters to large warehouses to help move materials from one area to another. The concept didn’t pan out and the two had been considering ways they could electrify their creation. That’s where Crewse came in as the expert in electric drive train technology. Together, they used the manufacturing space and equipment and paired it with Crewse’s electric bicycle converter to produce ebikes. Slowly the model started to take off.

The first Super73 product the trio produced together was born out of a heavily-modified Taco mini bike kit, a Southern California brand that was popular in the ‘60s, and combined it with a fat tire kids’ bike they bought at a chain outlet. Their first-edition Super73 had 500 orders in the first month of the startup’s Kickstarter campaign.

“All of us kind of realized, ‘Oh, we actually have to do this for real’,” Crewse says.

It took the group a year and a half to fill those initial orders. At the same time, however, they were working on the next generation of the Super73. Now, the company has grown to offer a line of ebikes, and will soon be expanding into electric motorcycles.

Now, with a successful company in their hands, Super73 still holds onto the same values of electrifying transportation, making it accessible and creating products for the next generation.

“One of the things that never gets old, I will tell you, to this very day, when I see one of our bikes blasting down, I see people having fun on it. I mean, it's just, it makes everything worth it,” says Crewse. “[For] people to be able to go and enjoy this thing that you know, that I got to experience 11 years ago…. It's deeply, deeply satisfying.”

Impulse Space Just Raised $308M to Build the Roads in Orbit
Impulse Space

🔦 Spotlight

Happy Friday, Los Angeles.

Space may not have roads, but it still has a transportation problem.

Rockets have become remarkably good at carrying satellites beyond Earth. Once those satellites reach space, however, getting them from one orbit to another can still be slow, expensive or impossible.

Redondo Beach-based Impulse Space wants to change that, and investors are giving it considerably more fuel for the journey.

The company raised a $308M extension to its Series D, bringing the round’s total to $808M. The new financing comes just over three months after Impulse announced the initial $500M raise and pushes its total capital raised above $1.3B.

Existing investors 137 Ventures, BANNER VC, DFJ Growth, Linse Capital, Lux Capital and Valor Equity Partners participated in the extension. Impulse did not disclose a valuation, but convincing existing backers to commit another $308M so soon after an already substantial round is a strong signal of confidence in both the company and the market it is pursuing.

Founded by former SpaceX propulsion executive Tom Mueller, Impulse is building vehicles designed to move satellites and payloads after they have already reached space. If rockets are responsible for getting cargo off the ground, Impulse wants to handle what happens after delivery.

Impulse Space

Its Mira spacecraft is built for precise maneuvering, payload deployment and proximity operations in orbit. Helios, scheduled for its first flight in 2027, is a high-energy kick stage designed to move payloads from low Earth orbit to destinations such as geostationary orbit in less than a day. The company has also introduced an electric propulsion system called Electra and a rideshare service aimed at making higher-energy orbits more accessible.

Together, those products represent something larger than a collection of spacecraft. Impulse is attempting to build a transportation network for an economy that increasingly needs one.

That need is becoming harder to ignore. More satellites are reaching orbit, governments are prioritizing responsive space capabilities and commercial operators want greater flexibility after launch. A satellite that can change position, reach a different orbit or respond quickly to a new mission is significantly more useful than one permanently tied to its original destination.

The U.S. government is already putting Impulse’s thesis to work. Helios was selected for the U.S. Space Force’s National Security Space Launch Phase 3 Lane 1 program, making it the first upper-stage prime awarded a position in the program. Impulse also received a $28M contract extension to provide two Mira spacecraft for additional Space Systems Command missions.

The company says its headcount has more than doubled over the past year as it expanded its facilities in Redondo Beach, Mojave, Boulder and Washington, D.C. The new capital will support further hiring, product development and facility growth as Impulse works to serve commercial, civil and defense customers.

It also recently appointed its first chief financial officer, Adam Townsend, who previously helped guide Vizio through an IPO and its eventual sale to Walmart. The hire is another sign that Impulse is preparing for a more complex chapter, one defined not only by engineering milestones but also by a growing capital base, government contracts and large-scale operations.

That is where this announcement becomes more interesting than its considerable price tag.

Impulse has already shown that Mira can operate in space. Now it must prove that it can turn several ambitious vehicles into dependable infrastructure. The difference between a promising spacecraft company and a transportation network is repetition: more missions, more customers and systems that work reliably enough to become part of how the space economy operates.

An $808M round gives Impulse the resources to pursue that vision. It also raises the expectations attached to it.

For Southern California, the financing reinforces the region’s role in the new space economy. Los Angeles helped build the original aerospace industry, and a new generation of companies is now developing the vehicles, factories and infrastructure intended to support life beyond the launchpad.

Impulse Space is tackling what may be the next big bottleneck. Getting to space is only the beginning.

Someone still has to get you where you are going.

      From Breaking Tech News to Backing It
      Image Source: Sources

      🔦 Spotlight

      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.

          Who Gave the AI Access?

          🔦 Spotlight

          Happy Friday, Los Angeles.

          The newest employee in the office does not need a desk, a salary or a coffee order. But it may have access to your company’s emails, financial records, customer data and software systems.

          That raises a fairly important question: Who decides what an AI agent is allowed to do?

          El Segundo-based cybersecurity company Saviynt is building its next chapter around the answer.

          Carrick Capital Partners announced this week that it closed a $600M continuation vehicle for Saviynt, including a new $255M investment in the company. The transaction allowed Carrick’s existing investors to either take liquidity or remain invested, while also providing liquidity to Saviynt employees through a tender offer.

          Continuation vehicles are not exactly known for making gripping Friday reading. The company behind this one is considerably more interesting.

          Saviynt develops identity security software that helps businesses determine who can access their applications, data and infrastructure. Increasingly, however, “who” does not refer exclusively to a person.

          Companies are deploying AI agents that can retrieve information, write code, communicate with customers and complete multistep tasks with limited supervision. These digital workers need access to company systems to be useful, but every new permission also creates another opportunity for sensitive information to be exposed or an unintended action to be taken.

          In other words, AI agents may be tireless employees. They are not necessarily trustworthy ones.

          Saviynt is addressing that problem through Zuma, its platform for discovering, securing and governing AI agents, large language models and other nonhuman identities alongside a company’s human workforce. The goal is to give businesses one place to determine what every identity can access, whether it belongs to an employee, a contractor, a software application or an autonomous agent operating at machine speed.

          The opportunity appears to be growing quickly. Saviynt has surpassed $300M in annual recurring revenue, up from approximately $10M when Carrick first invested. The company says bookings have increased by more than 80% this year while customer retention remains at 96%.

          The new investment was completed as part of the final close of Saviynt’s previously announced $700M Series B, which valued the company at approximately $3B. Carrick’s continuation vehicle was led by Coller Capital and co-led by HSBC Asset Management, giving the investment firm more time and capital to remain behind one of its strongest-performing companies.

          For Saviynt, the funding will support further development of its identity platform, deeper integrations with major cloud and software providers and its push to become a central security layer for the agentic workplace.

          That ambition reflects a broader change taking place inside companies. The first wave of enterprise AI focused largely on what the technology could generate. The next phase is about what it can actually do, and whether businesses can maintain control once AI moves from answering questions to taking action.

          Saviynt is betting that identity will become the gatekeeper.

          AI agents are gaining access to the digital workplace, whether corporate security teams are ready for them or not.

          Someone still has to hold the keys.
