The company grew to a $8.6B valuation (Series F) with 2,000+ paying customers and 1.3M developers secured through a product-led growth strategy centered on the Node.js community, leveraging innovative GitHub integration loops and programmatic SEO to drive adoption without reliance on traditional sales early on.
Somewhere is a global talent hiring platform that helps businesses find and hire remote workers across multiple countries. Nick Huber acquired the company (originally called Shepherd) for $52 million in a leveraged deal, investing $29 million of his own capital through a combination of $20M raised from investors and a $9M seller note from founder Marshall.

Creator Camp is an Austin-based accelerator/studio founded by a YouTuber with 800,000 followers that identifies and funds emerging creators making cinematic, scripted short-form video content. The company aims to produce high-quality films and videos on $100,000-$200,000 budgets that can achieve millions of views and theatrical distribution, capitalizing on the growing trend of professionally produced, acted-out content on platforms like YouTube, TikTok, and Instagram.
Pop Mart is a Chinese collectibles marketplace founded by Wang Ning in 2010 that grew from a single Beijing store to a $44 billion public company by 2024. The company monetizes designer toy blind boxes, with the LaBoubou character becoming a viral phenomenon after celebrity endorsements from Rihanna, BLACKPINK's Lisa, and other A-list figures, driving the stock from $7 billion to $44 billion in valuation within a year.
Chris Amon is a serial entrepreneur running 6+ profitable side hustles simultaneously, generating approximately $8,000 per day in cash flow.

Moonbug Entertainment, founded by Renee (formerly of Maker Studios and Disney), acquired undermonetized children's YouTube channels including Cocomelon, Blippi, and Little Baby Bum. The company scaled from ~$20M ARR in 2019 to $230M+ with $100M EBITDA in 4 years, then exited to Blackstone-backed Candle for $3 billion in 2023, demonstrating the massive value in aggregating and monetizing organic YouTube IP.
Third Web is a web3/blockchain developer platform founded by Furqan Rida that has built AI agents to automate business workflows. The company deployed 8-10 AI agents throughout their organization, including a sophisticated signup agent that researches inbound customers, identifies their company information, and sends personalized outreach emails. With 37 employees, Rida estimates the AI agents make the company feel like 80 people, demonstrating how a small team can achieve outsized productivity through AI automation.
Co-Fertility is a marketplace that bundles egg freezing with egg donation to solve the affordability problem in fertility services. By offering free egg freezing to women who agree to donate half their eggs, and charging $13,700 to recipients seeking eggs, the company creates a two-sided marketplace addressing a growing market (20,000 US women froze eggs in the prior year) with a controversial but strategic business model designed to generate earned media.
Pornhub was built by three Canadian college friends (Manos, Yusuf, Keaser) who leveraged YouTube's video hosting innovation to create a centralized adult content platform in 2007. The site grew from directory links to pirated content to becoming one of the top 6 most-trafficked websites in the US (2 billion visits/month) through exceptional SEO execution and organic growth, eventually reaching $100M+ in revenue before being sold multiple times to various owners including Fabian Tillman ($140M in 2010), and later to private equity.
Follow Up Boss is a vertical SaaS CRM built specifically for real estate agents to manage leads from platforms like Zillow and Redfin. Founded by Dan (from Australia, based in Wyoming) 12 years before exit, the company took 4 years to reach $100k MRR with just 11 employees, bootstrapped entirely through Facebook group engagement and word-of-mouth. The company sold for $500 million ($400M cash upfront + $100M earn-out), demonstrating the power of patient, niche-focused founder persistence and organic growth.
Sam Ratner dropped out of University of Missouri at 18 to build a mobile-first sports betting platform, recognizing that legalization would transform the U.S. gaming market. He built the company from credit cards and savings from a high school snow removal business, secured partnerships with the NBA and MLB as an authorized gaming operator, and sold the platform to Fubo TV for $40 million at age 23—before it even launched. Since then, he's explored numerous unconventional investments including purchasing a decommissioned riverboat casino and deeply analyzing a vending machine business.
Resi Club is a content-first platform focused on residential real estate coverage and data, co-founded by Anthony Pompliano and real estate expert Lance Lampard (former Fortune real estate editor). Launched just two months before this interview, the platform achieved profitability within the first month on a $100k initial investment and is positioned as the dominant voice in residential real estate commentary.
Moises Ali bootstrapped Native Deodorant from a kitchen table to a $100M exit to Procter & Gamble. He built the initial website in 3 days using WordPress and Woo Commerce, deliberately avoiding expensive design agencies. The brand grew through word-of-mouth and built a post-purchase upsell mechanism that generated $700k monthly in travel-size sales.
Blockworks is a crypto-native media and information company founded in December 2017 by Jason and co-founder Mike. Starting from cold LinkedIn outreach (300 messages/day), they bootstrapped to $25M+ revenue by building a media platform with podcasts, newsletters, conferences, and eventually a subscription research platform (Blockworks Research). The company scaled profitably from day one, with major conferences like Permissionless generating over $10M in revenue.
Brett Adcock founded Figure AI to build humanoid robots for commercial labor after selling his recruiting marketplace Vettery for $110 million and taking Archer Aviation (electric VTOL aircraft) public at a $1.5B valuation. He went all-in on Figure, nearly bankrupting himself personally while the company reached a $7M/month burn rate, ultimately betting that the humanoid robotics market could become one of the world's largest industries worth more than autonomous vehicles.
Spazless is a proposed nonprofit Reddit alternative that would operate similarly to Reddit but as a nonprofit that funnels revenue back to communities and moderators. The idea emerged during a major Reddit protest in 2023 when 93% of subreddits went dark to protest API pricing changes that would kill third-party apps like Apollo. The domain was registered as a conceptual project to capitalize on user discontent.
Sulamon Ali founded Tiny Co in 2009 to create mobile games for the newly launched iPhone App Store. Their first game, Tap Resort, generated $500-600K in revenue in its first month through a partnership with mobile ad network Tapjoy. After raising $18M from Andreessen Horowitz (with Mark Andreessen joining the board), they scaled to $20M revenue in year one and $40M in year two, but hit a wall when Japanese mobile gaming competitors drove customer acquisition costs from $1 to $9, destroying their unit economics and leading to significant monthly losses.
Cherry is a browser extension that helps accommodation businesses get direct bookings by showing customers better deals when they search on travel sites like Expedia and Booking.com. In four months, they onboarded nearly 1,000 partner properties across Australia, New Zealand, and Canada, with plans to launch in the US with 20,000 properties by November. They charge hotels a performance fee of $10/month plus $0.79 per click, significantly cheaper than the 30% commissions charged by major OTAs.
Zach Schachkeed built a mobile app version of the viral Wordle game over a weekend and achieved 30,000 organic downloads in just days, reaching the top of the App Store. However, his public celebration of this success on Twitter—despite previously tweeting against app clones—led to significant backlash from the tech community and ultimately resulted in Apple pulling all Wordle-branded apps from the store.
Storage Squad is a storage business built by Nick Huber that combines technical knowledge with a traditional, less competitive market. Huber champions what he calls "Sweaty Startups" - labor-intensive business models that he believes offer unique advantages and opportunities for entrepreneurs.
