Screaming baby to 300M downloads: The Dwellspring story
Show Notes
Brandon Reed - known as Be Reezy - is the founder of Dwellspring, an umbrella brand built around science-backed sleep and focus sounds. Before starting Dwellspring, Brandon spent a decade at Disney building mobile experiences - most notably the Disney Parks app, which hit over one million daily active users. He left Disney about two and a half years ago to go all-in on what started as a solution to his own sleepless nights as a new dad.
The flagship product is the 12 Hour Sound Machines podcast, which has grown organically to nearly 300 million downloads, 1.3 million weekly listeners across 143 countries, and a spot in the top 1% of all podcasts globally - without a single paid ad. The natural next step was a mobile app that brings binaural beats, custom mixing, and a creator marketplace to the same audience. Brandon is also exploring B2B deals with airlines, hotels, and sleep tourism brands, and has hardware concepts - including a Bluetooth sound machine and a smart stuffed animal called Sleepy Pete - in various stages of development.
From Screaming Baby to Podcast Phenomenon
The origin is as unglamorous as it gets: Brandon's baby would not sleep. Out of desperation, he stitched together twelve hours of brown noise, uploaded it as a podcast episode (podcasting had no file size ceiling, unlike music streaming platforms), and posted it for free. Spotify's algorithm picked it up in 2018–2019, and it spread without any promotion. Today, 210,000 people listen to his brown noise episode daily. The podcast became the proof of concept - and the audience - for everything that followed.
Brown noise, Brandon explains, acts like a “blanket for the brain.” It masks environmental distraction by filling the auditory field with a steady low-frequency hum, which short-circuits the brain's pattern-detection instinct. People with ADHD, autism, anxiety, and chronic insomnia report that his specific tuning is the only version that works for them. That specificity - the particular EQ curve and texture of Brandon's recordings - has become a genuine moat. You cannot easily replicate the resonance of a sound that 210,000 people choose daily.
The Podcast as Audience Pipeline, Not Business
Brandon is explicit about the mental model: the podcast is not the business. The podcast is the audience delivered to the business. This reframing unlocks the product roadmap. A podcast listener who trusts your audio quality and falls asleep to your recordings every night is the warmest possible prospect for a premium app with more features, deeper personalization, and ad-free playback. The conversion logic writes itself - and it does not require any paid acquisition.
He was already earning approximately $60,000 a month from podcast advertising while still employed at Disney. He used that validation to take a $100,000 loan - since fully repaid - to fund the app build rather than give up equity. The discipline of staying bootstrapped meant every dollar had to earn its place, and it forced a clarity about which features to build first.
What the Dwellspring App Actually Does
The app goes well beyond looping audio. The core differentiator is binaural beats: separate tones played into the left and right ears that create a perceived frequency in the brain - the difference between the two tones. A 200 Hz tone in the left ear and a 210 Hz tone in the right generates a perceived 10 Hz beat, which corresponds to alpha wave activity associated with relaxed focus. Targeting delta, theta, alpha, beta, and gamma frequencies allows the app to guide brain states for sleep, deep focus, meditation, or creativity.
A custom mixer lets users blend multiple sounds simultaneously - rain, brown noise, binaural beats, fan - at independent volumes. A creator exchange lets community members upload their own ambient recordings, giving the library a long-tail of environmental sounds beyond what Brandon can produce alone. A record-your-environment feature lets users capture sounds that work for them in context - a specific coffee shop hum, a hotel AC unit - and play them back at home. The subscription covers both ad-free podcast access and full app features.
Taste as a Durable Competitive Moat
In a category where anyone can record ambient audio, Brandon argues that taste - the specific artistic and technical judgment that goes into tuning a sound - is the actual barrier to entry. His brown noise is not the loudest, not the most technically perfect by a spectrogram, but it is the one 210,000 people press play on every morning. Listeners who have searched for alternatives and come back describe it as the only one that works for them. That preference is real, hard to copy, and has compounded over years of daily listening habits.
This is the same logic that makes certain music producers, chefs, or cinematographers irreplaceable despite abundant competition. The craft is learnable; the taste takes decades and is not transferable by cloning outputs. For a consumer wellness product where trust and ritual are everything, that is a meaningful position to hold.
B2B: Airlines, Hotels, and Sleep Tourism
The next growth vector Brandon is actively pursuing is B2B licensing. Airlines with seatback entertainment systems need sleep content for long-haul flights - he can deliver proven, audience-tested audio without requiring the airline to build or curate anything. Hotels leaning into the growing “sleep tourism” trend (designing entire experiences around sleep quality) need the same. Any digital experience with an existing audience that wants to offer better sleep and focus tools becomes a potential distribution partner.
The appeal to the B2B buyer is the combination of scientific backing (binaural beats, brown noise, peer-reviewed frequency research) and proven consumer behavior. This is not experimental - it has 300 million downloads of evidence. That framing makes the sales conversation easier and positions Dwellspring as a premium wellness layer rather than a commodity sound library.
Hardware: Sound Machines and Sleepy Pete
Brandon has two hardware concepts in development. The first is a physical Bluetooth sound machine with stereo detachable pods and magnetic mounts designed to attach to a bed frame, stroller, or crib - solving the use case where a phone playing audio is not convenient or safe. The device would be the Dwellspring audio experience in a purpose-built form factor, pulling the brand from a digital app into a physical product category with much higher shelf presence and retail distribution potential.
The second concept, currently paused, is Sleepy Pete - a stuffed animal with a Dwellspring sound core built in. The idea is to give children (and parents) a tactile comfort object that also delivers the proven audio benefits. Brandon paused it after discovering the regulatory complexity: an app-connected product with components that go near children's faces runs into FDA territory quickly. He made the call that the regulatory surface was not worth the distraction at this stage.

Frameworks
Podcast as Audience Pipeline
A podcast is not the business - it is the audience delivered to the business. Its job is to build trust, demonstrate quality, and create a warm pool of prospects for higher-value products downstream. Revenue from podcast ads is validation data, not the ceiling.
Taste as Moat
In markets where the output is easily replicable (ambient audio, photography, food), the durable competitive advantage is the creator's specific aesthetic judgment - their taste. Taste is observable in outputs but not transferable by copying them. Listeners who say ‘only yours works for me’ are describing taste as moat.
Bootstrapped Proof Before Equity
Brandon funded the app build with a $100K loan rather than giving equity, because the podcast had already proven demand and revenue. Bootstrapping forces a tighter product scope and keeps ownership intact. Take on capital only after you have something that de-risks the bet.
Regulatory Surface as a Go/No-Go Filter
When evaluating product extensions, map the regulatory surface early. The Sleepy Pete stuffed animal was a product Brandon believed in creatively, but FDA complexity for a connected device near children's faces made it a distraction at this stage. Complexity that is not yet worth managing is a valid reason to pause.
Living Expenses Cap as Financial Discipline
Brandon capped personal living expenses at $100K/year since getting married, regardless of business income. The cap forces him to invest the rest and removes lifestyle inflation as a pressure that could push him toward bad business decisions made out of personal financial need.
FAQ
How did the 12 Hour Sound Machines podcast grow to 300 million downloads without paid advertising?
Brandon uploaded his first twelve-hour brown noise recording to podcast platforms in 2018 primarily because podcasting had no file size limit - music platforms would not accept a twelve-hour track. Spotify's recommendation algorithm picked it up and spread it organically across its sleep and relaxation content graph. The specificity of the content (long, uninterrupted, consistent) aligned perfectly with the algorithm's signals for content people actually complete and return to. It has grown entirely through algorithm distribution and word of mouth.
What is brown noise and why does Brandon's version work differently for so many listeners?
Brown noise is a form of broadband audio weighted toward lower frequencies, creating a deep, warm hum - distinct from white noise (flat spectrum) or pink noise (midrange-weighted). Brandon's specific tuning - the EQ curve, density, and texture of his recordings - resonates with listeners in a way that generic versions do not. He attributes this to taste: the same indefinable quality that makes certain music producers' work identifiable. 210,000 daily listeners have habituated to his specific sound, which makes substitution difficult.
What are binaural beats and how does the Dwellspring app use them?
Binaural beats are an auditory illusion created by playing slightly different frequencies into each ear. The brain perceives the mathematical difference between the two tones as a third frequency. A 200 Hz tone in the left ear and 210 Hz in the right produces a perceived 10 Hz beat, corresponding to alpha waves associated with calm focus. By targeting delta (deep sleep), theta (meditation), alpha (relaxed focus), beta (alert productivity), or gamma (high cognition) frequencies, the app can guide the listener's brain state. Requires headphones for the effect to work.
How did Brandon afford to build the app without outside investment?
He was generating approximately $60,000 per month from podcast advertising while still employed at Disney. That income validated the audience and gave him the financial footing to take a $100,000 personal loan to fund the app build rather than seek equity investment. The loan has since been repaid. He left Disney once the app was far enough along to absorb his full attention.
What B2B markets is Brandon targeting with Dwellspring?
Airlines (seatback entertainment systems for long-haul sleep), hotels participating in the growing sleep tourism trend, and any digital product with an existing audience that wants to offer science-backed sleep and focus content. The pitch is simple: 300 million downloads of evidence, binaural beat science, and a proven consumer brand - plug it in without having to build or curate anything.
What happened to Sleepy Pete?
Sleepy Pete was a stuffed animal concept with a Dwellspring sound core built in - designed for children who associate the brand with sleep. Brandon paused it after discovering that an app-connected product designed to sit near a child's face triggers FDA regulatory requirements. He determined the regulatory complexity was not worth the distraction at this stage of the business and shelved it until the core app and B2B pipeline are more mature.
What advice does Brandon give to college students interested in entrepreneurship?
He would study electrical engineering. His current fascination with hardware - the sound machine product with detachable stereo pods, the Sleepy Pete concept - bumps up against the limits of his software-first background. Understanding circuits, product design, and manufacturing would open the hardware layer of the business that is currently the most constrained by his team's capabilities.
