one-time Startups

MetaFizzy is a one-person operation by Dave DeSandro that sells JavaScript libraries and tools to developers. Starting with Masonry in 2009 (a free, open-source grid layout library), Dave launched MetaFizzy in 2010 to monetize related products like Isotope, Packery, Flickety, and Infinite Scroll using a GPL licensing model that requires commercial users to pay for a closed-source license. The business grew from $25k in year one to $120k annually by 2015-2016, allowing Dave to quit his job at Twitter in 2014.

Dick At Your Door is an e-commerce novelty product company selling chocolate penises, started as a joke between friends in a garage in 2016. The business grew to $25k/month ($300k/year ARR) primarily through viral social media content, PR coverage (notably a Huffington Post feature that provided initial traction), and word-of-mouth marketing. Adam attributes the rapid scaling to the viral nature of the product, strong content marketing around chocolate and pranks, and persistent outreach to press and marketing partners.

Josh Comeau built CSS for JavaScript Developers, an interactive online course combining videos, articles, widgets, and mini-games to help JS developers master CSS. He validated the idea with a one-week pre-order campaign targeting $50k in sales and instead generated $550k in revenue from nearly 5,000 sales. His success came from building in public on Twitter, maintaining a high-quality blog that attracts 60-90k monthly visitors, and leveraging an email list of 20k subscribers.

CROSSNET is a four-way volleyball net company founded by Chris Meade and two childhood friends that grew from a late-night brainstorming session to a $300k/month business in less than two years. The team built the product by prototyping with Walmart nets, iterating with manufacturers for a year, and strategically distributing units to influencers who created engaging content. Their growth came from repurposing influencer videos into Facebook and Instagram ads while continuously optimizing their Shopify store with conversion tools like Privy, Klaviyo, Hotjar, and Carthook.

Louie Nichols launched the first version on May 1st, 2019, selling out 7 spots in 17 minutes via email to his newsletter, generating $2,000 in revenue. By iterating rapidly through multiple cohorts and emphasizing community over purely evergreen content, he grew to $30,000 in revenue from his third cohort while building toward his goal of making the course free.

James Traff made $280,000 in approximately 5-6 weeks from a custom iOS icon set that took only 2 hours to create and package. The breakthrough came when his Twitter screenshot of a customized iPhone home screen went viral, followed by MKBHD featuring the icons in a YouTube video that reached 6 million views. His success was built on 7 years of design experience, a habit of sharing work on social media, and the ability to quickly capitalize on trending opportunities using no-code tools.

Thanksbox is a digital card and cash collection platform that lets teams celebrate occasions (birthdays, departures, weddings) without the friction of physical cards. Founded by Val Hinoff in May 2020 during the pandemic, the bootstrapped SaaS reached $18,000 MRR within 15-16 months by identifying a strong product-market fit with built-in viral loops (users must share the card to use it) and scaling via Google Ads with a $2 cost per acquisition against a $5.99 base price point.

Big Ass Fans started in 1999 with founder Kerry Smith manufacturing and selling large-diameter ceiling fans (6-24 feet) for industrial spaces. Despite expecting to sell 1,000 fans in the first year, they sold only 142—but received positive customer feedback that gave Kerry faith to continue. Over 19 years of bootstrapped growth, relentless R&D investment, and a focus on direct customer relationships, the company built an 80% market share and sold for $500 million in 2017, with Kerry distributing $50 million in proceeds to 150+ employees.

Peak Design started when founder Peter Dering quit his construction engineering job with $25k in savings to build a camera clip after struggling to carry his camera during a four-month backpacking trip. Using SketchUp and crude prototypes, he validated the idea and launched on Kickstarter in 2011, raising $364,000 in their first campaign and becoming the second most-funded project on the platform at the time. The company has since grown to $65-70M in annual revenue with just 38 employees through disciplined product innovation, bootstrapped growth, and a focus on solving real problems rather than marketing.

Paul built and sold a private-label e-commerce business on Amazon FBA, starting with $5,000 and no employees while working full-time.

Started five years ago despite nearly universal doubt from her network, the company targets women aged 25-45 who struggle to get meaningful health testing through traditional healthcare channels. Cheek's personal experience spending over $2,500 on fragmented blood tests without clear results or communication from doctors motivated her to create a more accessible testing solution.

Sophia Amoroso built Nasty Gal from a solo vintage clothing eBay store into a $100M+ revenue e-commerce fashion brand, raising $50M from Index Ventures at a $350M valuation in 2012. After rapid growth, the company faced challenges and eventually declined, leading Amoroso to pivot to Girl Boss, a media and community brand that includes conferences, a Netflix series, and social platform, which she sold to Attention Capital.

Abhishek built an arbitrage service exploiting Uber's referral credit system, which offered $10 credits to US accounts while Indian rides cost 30-50 cents.
