'There Will be Drastic Changes to Come in Music Creation': Output Raises $46M to Change How Music is Made
  • L.A.-based Output, a bootstrapped business founded in 2013 to help musicians overcome writer's block, announced its first ever fundraise, of $45 million from Summit Partners.
  • The company serves a range of musicians from hobbyists to professionals, providing them a library of loops and samples that they can then manipulate into unique songs of their own.
  • Immediate plans are to nearly double its staff and expand its product platform, with future goals of leading the evolution of digital music production.

Gregg Lehrman was no stranger to music composition. He had worked under world-famous composers such as Hans Zimmer writing music for film and TV and had produced big projects with BMG music publishing. But after setting out on his own, he found himself suffering from writer's block.

So, he said, "I made a piece of software for myself, as a music-maker — with no intention of starting a company."


Lehrman's tool, however, ultimately became a music-tech company called Output. Based in L.A.'s Chinatown district, its mission is to help people start making music.

Seven years after it was created, Output has agreed to its first ever fundraise: a $45 million minority-stake investment from Summit Partners.

"I think there will be drastic changes to come in music creation," Lehrman said, "and we want to be at the forefront of it."

His investors agree.

"We believe Output has the potential to reinvent the digital music production market," said Andrew Collins, managing director at Summit and lead investor on the deal. Collins will now join Output's board.

"The holy grail in digital music-making is to make it super easy for musicians to find content that they like and then make it sound unique to them, and that's exactly what Output does," Collins told dot.LA.

The list of artists and projects that have used Output is impressive: Kanye West, Coldplay, Justin Bieber and Rihanna among them, as well as the soundtracks to "Game of Thrones," "Stranger Things" and "Black Panther."

The company broke $1 million in its first year with no advertising, Lehrman said: "just a viral video and a good product." That first product line – which included digital instruments and effects – was software geared toward professional musicians, who purchase it for an upfront fee.

In 2018, the company added a software-as-a-service (SaaS) product, called Arcade, which became particularly popular among musical hobbyists and digital-music newcomers. For a $10 monthly subscription, users receive access to thousands of loops and samples created by Output, which they can then manipulate and turn into their own unique tracks.

Most customers today use Arcade in conjunction with a digital audio workspace like Logic, Ableton or ProTools. Songwriters, whether professional or amateur, can set their rhythm and key, pull from Output's library of sonic building blocks and mold them like musical clay. Users can also upload and work with their own digital audio files.

Over time, Output has seen both its user base and its revenue streams shift away from the pros – which Lehrman said is a customer base with a natural limit – and toward hobbyists and digital-production newcomers.

Arcade, its SaaS product, has seen a 300% increase in monthly recurring revenue over the past 12 months. In just two years, it's grown to generate about 60% of Output's income.

"In the world of SaaS, it is incredibly rare to see both exceptional growth and capital efficiency." Collins said. "You don't see SaaS software growing this fast, profitably, fully bootstrapped. There's not a lot of those out there."

As the popularity of Arcade has grown, Output's user base has shifted to about one-third professional musicians, one-fourth digital-music newcomers, and the rest hobbyists who are "really into making [digital] music."

Collins also likes the market tailwinds that Output is riding — namely, the democratization of music ideation and distribution. Output enables musicians to create new sounds, while platforms like Spotify and Soundcloud allow anyone to publish their tunes with just a few clicks.

The company's technology stack is a combination of digital signal processing (DSP) algorithms written in C++ and some machine learning. "We're going to see that continue to expand," Lehrman said.

Output also has a line of furniture and hardware products designed to help music-makers build out their home studios. It is currently working with Barefoot Sound – which Lehrman called "the Rolls Royce of speakers" – to manufacture a new speaker line.

With its new cash, Output plans to grow its staff, which currently numbers about 60. "We'll grow to north of 100," Lehrman said.

It will also build out its product offering, adding new tools to Arcade like digital instruments and expanding its mobile capabilities.

"We feel strongly we can build a unified ecosystem that once you're in, you're familiar with everything," Lehrman said. "You don't have to learn 100 different applications; it can do 100 different things but you won't feel lost."

Collins pointed to several competitors, including Splice, LANDR, iZotope and Native Instruments, but noted that "nobody else has integrated a very robust curated library of content – sounds, loops, well-organized beats – that musicians can pull from and pull into a workflow engine (the software) and manipulate those sounds to create something that is completely unique."

Lehrman and Collins separately emphasized the Output team's passion for music. 50 of the 60 employees today make music on a daily basis, Lehrman said.

Summit primarily focuses on founder-led bootstrapped companies, which it provides with on-demand services like marketing and engineering.

"Management sets the agenda," Collins said.

For Lehrman, that'll be to further leverage technology: not to create music itself, but to help people create, just like it helped him overcome his own writer's block those years ago.

    "From the first product to the last product," he said, "it's been about helping people be creative."

    🏈Snapchat’s Super Bowl Push & Apple’s New App 📲—Here’s What’s New

    🔦 Spotlight

    Hello, Los Angeles!

    With Super Bowl LIX coming up this Sunday, the buzz isn’t just about the Chiefs vs. Eagles matchup—it’s also about how tech is shaping the experience. From Snapchat’s interactive game-day features to Apple’s latest product launch, there’s plenty happening beyond the field.

    Snapchat’s Super Bowl Features

    If you're watching the game, chances are you’ll be on your phone just as much as your TV. This year, Snapchat is rolling out AR Lenses, live score updates, and Spotlight challenges to make game day more interactive. Want to try on your team’s jersey? There’s a Lens for that. Need real-time updates? Snap has them covered. Attending the game in New Orleans? Live Location can help you track down friends in the crowd. As the second-screen experience becomes more ingrained in live sports, Snap is making sure it’s front and center.

    Snap’s New Initiative: The Department of Angels

    Super Bowl Sunday is about competition, but what happens when the challenge isn’t on the field? Yesterday, Snap announced The Department of Angels, a new initiative aimed at supporting communities recovering from disasters, offering independent funding and resources to help them rebuild on their own terms. Backed by $10 million from Snap Inc., Evan Spiegel, Bobby Murphy, and the California Community Foundation, the program shifts away from traditional corporate donations and toward grassroots, community-led recovery efforts. Could this be a model for how tech companies engage with real-world crises in the future?

    Apple Wants to Change How You Send Invites

    Apple is stepping into the event invite space with Apple Invites, a new app designed to make organizing gatherings simpler. Competing with platforms like Partiful and Evite, Apple’s version integrates directly into iMessage and Apple Calendar, making it an easy, built-in option for Apple users. With so many invite platforms out there, will Apple’s streamlined approach become the go-to for iPhone users, or will it simply be another tool in the mix?

    Where to Watch Super Bowl LIX

    The Chiefs and Eagles face off this Sunday at 3:30 PM PT on FOX. Here’s a helpful link to directly access ways to watch. You can stream the game for free on Tubi, or catch it on YouTube TV, Hulu + Live TV, NFL+, and fuboTV. And of course, we’ll be watching to see which brands—including tech giants—deliver the most memorable ads of the night.

    Between Snap’s game-day integrations, its push to support community-led recovery, and Apple’s move into digital invites, this week is full of shifts in how we connect. Which of these will redefine the way we interact? We’ll be watching.

          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 app integrates live data, satellite imagery, and community reports to send updates directly to users. Information includes fire locations, evacuation orders, and air quality indices, empowering quick, informed decisions. Its community-driven ethos—with contributions from locals, firefighters, and volunteers—ensures hyper-local and timely updates, filling gaps where traditional news outlets often fall short.
