History

A Santa Barbara Start

Sonos’ story begins before their founding in the mid-1990s when John MacFarlane (co-founder) moved to Santa Barbara to pursue a Ph.D. at the University of California-Santa Barbara. MacFarlane's path changed from academia when he saw the rising potential of the Internet. Along with the other future co-founders Tom Cullen, Trung Mai, and Craig Shelburne, he co-founded Software.com, a company in Internet-based messaging services. The company was a success, eventually merging with Phone.com in 2000 for $6.9bn in stock to create Openwave. After the merger, the quartet faced a crucial question: What next?

As they brainstormed what to do next, the four drew upon their collective experiences from the height of the Internet boom. Tom Cullen, reflecting on that period, pointed to four big insights that shaped their thinking. First, the Internet was becoming a programmable platform. Second, hardware costs were collapsing, making powerful components like integrated circuits and CPUs affordable. Third, digitization was just beginning, unlocking vast new possibilities. And fourth, wide-area networks were creating new opportunities for local-area networks—networks that could power homes in ways previously unimaginable.

Turning to Music: A Vision Ahead of Its Time

The founders' shared love for music eventually brought them to the idea that would define Sonos. The co-founders saw the mix of stagnation and innovation in the music industry: Napster, the peer-to-peer digital audio-sharing company, exposed millions to the possibilities of digital music. Yet, even though people were starting to see the intersection between the internet and music, CDs were still the main way to listen to music. Finally, the co-founders saw how clunky and complicated home audio systems were, in addition to requiring professional installation and a substantial budget.

MacFarlane and his co-founders saw an opportunity to create a system that would allow people to listen to any song in their home without the struggle of tangled wires. Why hadn’t anyone else solved it? In 2002, the technology to achieve this vision didn’t exist. High-speed Internet was in its infancy—fewer than 16mm U.S. households had broadband, and streaming music services like Spotify and Pandora were years away.

This only confirmed to the co-founders the need they saw in the music industry for this technology. They believed that they could create a new type of home audio system, one that would anticipate the future needs of consumers and position Sonos as a leader when the market caught up.

The Wireless Challenge: Making the Impossible Possible

A wireless audio system would be as hard to develop as they thought. The main problem was the disconnect that most home audio systems required physical connections while wireless technology was still in its early stages. There were no off-the-shelf solutions that Sonos could adapt. The team had to build everything from the ground up, from the software that would control the system to the hardware that would transmit the audio wirelessly.

One of the biggest technical challenges was getting audio to multiple speakers without any noticeable lag or gaps in sound. Early prototypes produced horrible noises and frequent dropouts. The engineering team spent months debugging the system, at one point resorting to wearing headphones to block out the screeching sounds from the speakers.

To solve these problems, Sonos developed a proprietary technology called delegation, which allowed the system to hand off the role of the master speaker without interrupting the music. They also implemented a novel approach to time-stamping the digital bits of music, ensuring that multiple speakers would stay perfectly in sync. 

Although the wireless problem still was present. The early prototypes relied on PCs wired together, as the team struggled to get the wireless component working. MacFarlane was adamant that the system had to work over Wi-Fi, which meant the team needed to develop its own wireless networking solution.

The Mesh Network

The solution to the wireless problem was mesh networking, a technology previously used in military and industrial applications. Mesh networking allows devices to communicate with each other directly, rather than relying on a central router, which was critical for ensuring that Sonos speakers could maintain a strong connection even if they were spread out across a large home.

With help from faculty at UC Santa Barbara, a consultant, and a vendor, the team taught itself mesh networking and, within six weeks, developed a working prototype. While the results were promising, there was still much to do for the Sonos team. 

By early 2004, Sonos had a basic working system, but it was riddled with bugs. The prototypes couldn’t communicate wirelessly from even ten feet apart, and the team lacked the tools and debuggers needed to identify the issues. Testing was done in the homes of Sonos employees, where the unpredictable nature of real-world environments exposed new problems. One particularly vexing bug could only be reproduced in one employee’s house, leading the team to use a packet sniffer to track down the issue.

In the summer of 2004, with prototypes finally starting to function reliably, Sonos began showing the system to industry insiders. The reaction was electric. At the 2004 D: All Things Digital conference, Sonos demonstrated its system in the hallways while Steve Jobs was on the main stage unveiling Apple’s Airport Express—a competing product that required users to control the music from their computers. Sonos’ system, by contrast, allowed users to control music directly from a handheld controller, a major advantage that set it apart from Apple’s offering. 

The First Product: The ZP100

After three years of development, Sonos launched its first product. On January 27, 2005, the company shipped out the ZonePlayer 100, a wireless amplifier that could stream music to speakers in any room of a house. While they weren’t the first company to bring a consumer-grade speaker to market, they were the first company to bring wireless multi-room audio to consumers. Accordingly, the feedback was positive. Walt Mossberg, an influential tech columnist for The Wall Street Journal, called it "the first wireless system I’ve seen that works reliably and simply in playing music across multiple rooms."

Despite the positive reception from critics, Sonos was still struggling. In 2005, the internet was still in the process of becoming mainstream. What this meant for Sonos was many consumers didn’t see the need for a wireless music system due to a lack of internet connection and streaming services to select the music. Additionally, Sonos’ price point—$500 for a single ZonePlayer—was too much for the average consumer to justify.

Perseverance Through Recession: Surviving the 2008 Financial Crisis

Another three years later, times for Sonos only became harder as the global financial crisis of 2008 hit. Consumer spending plummeted, and Sonos, still a young company, was suddenly facing dissolution. With sales drying up, the founders had to make the decision to forego their salaries. The co-founders were willing to do anything to continue Sonos' survival. At one point, Trung Mai even dipped into his personal savings to pay employees out of his own pocket.

Despite the circumstances, Sonos held strong. MacFarlane refused to cut costs by compromising on product quality or laying off employees. Instead, he urged the team to continue their focus on innovation and improving the user experience, believing that the market would eventually catch up to their vision.

The Rise of Streaming: A Perfect Storm

MacFarlane’s bet paid off. In the years following the recession, several trends converged that positioned Sonos for explosive growth. High-speed Internet became ubiquitous, and streaming music services like Pandora, Spotify, and Apple Music began to take off. The idea of owning digital files or physical media gave way to the convenience of streaming, and suddenly, Sonos’ wireless, whole-home audio system seemed like the perfect product at the perfect time.

Sonos was quick to capitalize on this shift. They struck partnerships with major streaming services, allowing users to stream music from their phones or computers directly to their Sonos speakers. The company's marketing focused on a seamless user experience that made it easy to fill any room (or house) with music.

Expansion and Continued Innovation

As Sonos grew, so did its product lineup. The company introduced a wider range of products, including the Play:1, an affordable, compact speaker that brought Sonos into more homes than ever before. They continued to innovate on the software side as well, with regular updates to the Sonos app. Sonos was able to keep growing its segments in the audio market and tapped into the smart speaker space with the introduction of voice control through integrations with Amazon Alexa and Google Assistant. Overall, Sonos has established its value proposition with multi-room audio and continues to expand the audio ecosystem around it. Through the Sonos app or voice control, consumers can manage both wired and wireless speakers inside and outside their homes, creating a product lineup that encourages customers to expand their Sonos collections by offering speakers fit for various environments.

IPO

After aggressive expansion into many different facets of the speaker industry, Sonos continued to produce negative earnings and needed to raise more capital. For reference in 2016, it posted a $38.2mm loss on $901.3mn in revenue and in 2017 a net loss of $14.2mn on $992.5 million of revenue. Like so many other tech companies of the time, Sonos went through the traditional IPO process with Morgan Stanley and Goldman Sachs to sell 13.9 million at $15 a piece, raising $208.5 million [20]. In August 2018, Sonos started trading on NASDAQ under the ticker SONO with a total valuation of $1.5bn.

Thriving in the Pandemic, Battling Headwinds Since

Sonos achieved 30% topline growth in 2021, driven by a surge in demand for home theater systems due to lockdowns and the growing popularity of streaming services. This, coupled with their five-year product life cycle—which was designed to encourage customers to gradually expand their personal speaker ecosystems—led to an advance on future demand, which ultimately hindered subsequent growth. In 2022, record inflation significantly reduced consumer spending power, while many prioritized spending on experiences like travel after being restricted during the pandemic. As a result, Sonos has faced significant headwinds, with margins suffering as they maintained similar levels of R&D spending despite declining revenues in an effort to preserve their lead in audio technology.

Overview

As previously mentioned, Sonos sits in the consumer electronics industry that covers devices used for communication, entertainment, or information purposes. The market is dominated by well-known players such as Apple, Samsung, Huawei and Sony. Big Tech companies like Google and Meta have been entering the market as well through AR/VR technology but also through smart home technology. Looking forward, the industry will continue to grow the tech ecosystem people have in their homes and presents many opportunities for companies to look to consolidate or partner their technology for better convenience for consumers.

Sonos is part of  TV, Radio & Media making up 20% of a ~$100bn industry [11]. Further subdivided, Sonos is in the global wireless audio device market. A market with a projected CAGR of 22.2% from 2023 to 2028. This expansion is driven by two key trends:

1. Rising Adoption of Wireless Technology: Smart home adoption is growing, with 19% of households globally having a smart home in 2024, compared to just 9% in 2019, when the rate was half as much [19].

2. Technological Advancements in Consumer Electronics: The increasing prevalence of advanced smartphones, computers, and gaming consoles has a derived demand on speakers and sound systems as the price per unit decreases for things like cell phones and TVs. To elaborate, a TV in 1954 cost $110.20 per square inch compared to today where it cost ~$1 per square foot [12].

Cyclicality of Consumer Industries

Consumer sectors are notoriously cyclical. The graph above shows US consumer sentiment based on answers regarding household’s expected financial situation, their sentiment about the general economic situation, unemployment and capability of savings [13]. As you can see, the sentiment pivots up and down as perceived economic conditions change. Obviously this has a detrimental effect on consumer electronics as discretionary spending shifts down. This causes many companies in the industry to fight for pricing power either from intellectual property like Sonos has done or focusing on the lifestyle/prestige of the brand that keeps consumers coming back like Apple has done with the iPhone and the stigma of green text bubbles [14].
