Born of Writer's Block, Output Raises $46M to Make Creating Easier for Musicians
  • 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."

    Match Goes Niche With $100M Move

    🔦 Spotlight

    Hello Los Angeles,

    It’s May, and LA is about to have one of its more important weeks.

    The Milken Institute Global Conference 2026 returns to Beverly Hills next week, bringing together thousands of investors, operators, policymakers, and executives. It’s one of the few places where public markets, private capital, and tech actually overlap in the same rooms, and where you can usually get an early read on what capital is leaning into before it fully shows up in the data.

    This year, one theme is already starting to surface. Platforms are getting more specific, not more broad.

    This week’s news is a good example.

    Match Group is investing $100 million into Sniffies, a fast-growing, location-based platform built for gay, bi, trans, and queer men. It’s a notable move for a company best known for mainstream dating apps like Tinder and Hinge, and it signals a deeper push into more niche, community-driven platforms.

    Sniffies operates very differently from traditional dating apps. It’s more real-time, more map-based, and more focused on immediacy than long-term matching. In other words, it’s built around behavior, not profiles.

    And that’s what makes the investment interesting.

    For years, the dominant strategy in consumer platforms was scale, build one product that works for everyone. But what we’re seeing now is the opposite. The platforms that are gaining traction tend to be the ones that understand a specific audience deeply and build for how that group actually behaves.

    Match leaning into that shift isn’t just about expanding its portfolio. It’s a recognition that growth is coming from focus.

    And in a city like Los Angeles, that’s usually where things start.

        Netflix Doubles Down on LA

        🔦 Spotlight

        Hey Los Angeles.

        Goodbye Coachella, hello Stagecoach. The desert doesn’t stay quiet for long, and neither does LA’s entertainment machine.

        This week, that momentum showed up in a more permanent way.

        Netflix is expanding its footprint in Los Angeles with a major move to take over and invest in Radford Studio Center, a historic production lot in Studio City. The company is planning a long-term transformation of the site, with upgrades to soundstages, production offices, and infrastructure designed to support the next generation of film and television production.

        It’s a notable shift in a moment when production has been under pressure in California, with studios increasingly looking outside the state for cost advantages. Netflix going deeper in LA, and specifically into a legacy studio lot, signals a different kind of commitment. Not just to content, but to where that content actually gets made.

        And it comes at a time when the streaming wars have matured. Growth is harder, budgets are tighter, and the focus has shifted from scale at all costs to efficiency and control. Owning or operating more of the production environment gives Netflix tighter control over timelines, costs, and output.

        For Los Angeles, it’s a reminder of what still anchors the city. Even as AI, defense tech, and infrastructure startups continue to rise, entertainment remains one of the few industries where LA isn’t just competitive, it’s foundational.

        Different headlines each week, but a consistent theme underneath them. Whether it’s power, autonomy, or content, the companies that matter are investing in the layers they don’t want to outsource.

        And in this case, that layer is Hollywood itself.

            A $26M Push Into Power in LA

            🔦 Spotlight

            Hello, Los Angeles.

            Coachella Weekend 2 is here, which usually means LA is either heading back to the desert or happily staying put this time around. Back in the city, the focus this week is less about music infrastructure and more about something far more critical, power.

            That’s where this week’s news comes in.

            Critical Loop, a Los Angeles-based energy startup, raised a $26 million Series A to tackle one of the least talked about bottlenecks in tech right now, grid interconnection. In simple terms, it’s the process of getting power to where it’s needed, and increasingly, that process is too slow to keep up.

            Critical Loop is building modular microgrid systems that can be deployed in days instead of years, giving industrial operators, data centers, and other energy-heavy users faster access to power without waiting on traditional grid upgrades. The round was led by Conifer Infrastructure Partners and Hanover, with participation from Better Ventures, Climate Capital, Adapt Nation Capital, and Cyrus Ventures.

            The timing here matters. Between AI infrastructure demands, electrification, and a broader push toward domestic energy resilience, power is quickly becoming a gating factor for growth. You can build the data center, the factory, or the next big thing, but none of it works if you can’t turn it on.

            That’s what makes companies like Critical Loop worth watching. They’re not building the flashiest part of the stack, but they’re solving for the piece everything else depends on.

            And in a city that knows a thing or two about scaling ambition quickly, that might be the most important layer of all.
