Thrive Digital is a performance marketing agency founded by Jonathan Becker that has grown from a 10-person Vancouver-based consultancy to 130 employees managing approximately $500 million in annual ad spend. The company got its breakthrough when Becker transparently disclosed an arbitrage exploit he had discovered in Uber's referral program at a TED conference afterparty, which led to Uber hiring them to fix the vulnerability and then employing them for 10 years. Today, Thrive works with major brands like Asana, Square, Masterclass, and Tempurpedic, focusing on sophisticated creative testing, attribution modeling, and channel diversification as core growth levers.
Forget the Funnel is a growth consulting agency founded by Georgiana Laudi and Claire Selentrop in mid-2017 that helps B2B SaaS companies accelerate growth by replacing traditional funnel metrics with a customer-centric journey mapping approach. Working with companies like SparkToro and others, they've consistently driven significant conversion improvements—including an 89% increase in website conversion rate for a social media tool and doubling trial-to-pay conversion rates—by identifying ideal customers, mapping their experience, and optimizing each milestone for value delivery.
GitHub Copilot is an AI pair programmer that provides real-time, multi-line code suggestions powered by OpenAI's Codex model. Incubated within GitHub's R&D team (GitHub Next) after OpenAI's accidental mass cloning of GitHub repositories, it evolved from early experimentation to a technical preview that generated viral enthusiasm before achieving general availability. The product represents a fundamental shift in developer productivity, with Python developers writing approximately 40% of their code with Copilot assistance.
Beehive is a newsletter platform that grew from zero to $30M ARR in four years by leveraging founder Tyler Denk's credibility from scaling Morning Brew's referral program. The company acquired its first customers through direct outreach to 400 waitlist signups, converting 25% in early months through personalized founder engagement. Growth was powered by shipping one marketable feature weekly, building in public via investor updates, and maintaining a social-first company culture where every employee is distribution.
Franzy is a SaaS platform disrupting the franchise broker industry by providing transparent access to all 4,000 franchise brands with AI-powered matching, replacing opaque brokers who charge 60% commissions on hidden portfolios. Alex, a serial entrepreneur who previously built 2U Laundry and made his initial wealth in college laundry services, is scaling Franzy while building a 50-100 unit franchise portfolio through operating partners, targeting $5M+ annual revenue from franchising.
Tiny is Andrew Wilkinson's investment holding company that acquires and operates profitable businesses. Starting with $4-5 million in seed capital from his design agency MetaLab's profits in 2013, the company has grown to manage over $300 million in revenue across 30 businesses, with $65 million in ARR and $40+ million in EBITDA. The company went public via reverse merger in 2021 and now manages a $200 million fund alongside its core operations.
Ann Malume founded Saladcore, a premium Pilates studio, after discovering the business model while living in LA. Starting with $150k in initial capital (licensing fee $25k, buildout $150k, financed machines ~$70k), she opened her first location in DC and generated over $100k in revenue in month one. Through rapid expansion (5 locations by end of year one), strong branding ("Create the strongest version of yourself"), and word-of-mouth growth, she scaled to 27 locations doing ~$700k each by 2017 ($19M+ annualized revenue). She sold a minority stake in 2017 at a ~$60M valuation and exited completely in April 2023 (9.5 years after launch) for approximately $350M.
Peter Rahal co-founded RX Bar in 2012 with $5,000 of his own money (plus $5,000 from co-founder Jared) in his mom's basement in Chicago. By identifying CrossFit as an underserved distribution channel with high velocity (80 bars/week vs. 1-4 in convenience stores), he scaled to $2M, then $7M, then $160M+ in revenue within 5 years before selling for $600M. A strategic rebrand emphasizing simple, whole-food ingredients (three egg whites, two dates, six almonds, four cashews) helped him cross into mainstream retail. Now he's launched David Bar, a protein-dense alternative with 26-27g protein and ~150 calories.
FireCrown Media, founded by Craig Fuller (also founder of FreightWaves), acquired Flying Magazine in 2021 as a side project and scaled it into a $50M ARR media holding company. The business model inverts traditional magazine economics: instead of making money from readers, FireCrown uses media to acquire high-net-worth customers for higher-margin products like luxury real estate (an airport community development project in Tennessee with $25M in pre-deposits), jet brokerage, and marina investments across 44 magazine titles in expensive hobbies.
Reddit was founded by Steve Huffman and Alexis Ohanian in 2005 after being accepted into Y Combinator's first batch, inspired by Paul Graham's observation of delicious.com's popular links feature. The founders bootstrapped early growth by creating 30 fake accounts with different personalities to generate initial content and conversation, solving the chicken-and-egg problem of community platforms. After 16 months, they sold to Condé Nast for $10 million, and later bought it back; the platform has since grown to become one of the top 10 most visited websites globally despite remaining unprofitable.
The Milk Road is a crypto-focused newsletter that grew by delivering daily crypto news curated by founders who were personally invested in the space. The publication succeeded by focusing on genuine interest and quality content rather than pure metrics like subscriber count, building a valuable audience of crypto investors with real purchasing power.
Threads is Meta's text-based social network launched in July 2023, reaching 100 million users in its first week by leveraging Instagram's existing user base. The platform positioned itself as a kinder, more moderated alternative to Twitter, with Meta's 20 years of experience managing abuse and spam. Early traction shows potential to disrupt Twitter despite questions about long-term retention and whether it can sustain growth beyond early adopters.
Vongol was a mobile video ad network founded by Jack Smith that revolutionized app monetization by charging based on app installs rather than video impressions. Starting with mockup-driven cold outreach that generated ~$1M in developer commitments, the company scaled to ~$1M in daily revenue within seven years and sold for approximately $800M. The company's competitive advantage included proprietary iPhone screen recording capabilities and direct relationships with app developers.
Doug DeMuro, a popular YouTube car reviewer with 4 million subscribers, launched Cars and Bids in June 2020 as a modern alternative to Bring a Trailer. The platform focuses on 1980s-onward cars and generated 75 million in gross sales in 2021. In 2022, Doug sold a majority stake to Churn Group (a PE firm specializing in creator-led businesses) for approximately 40 million dollars, allowing him to scale operations while maintaining creative control.
Maitab is a 29-year-old independent sponsor who acquires distressed D2C e-commerce brands and turnarounds them using operational excellence and rapid cash recovery strategies. Starting from a health issue at 17, he built several seven-figure e-commerce businesses in guitars and pedals before pivoting to private equity-style investing. His current portfolio includes three majority-owned platform companies (SoloWood Flowers, a succulent company, and an apparel brand) worth mid-eight figures in revenue, plus minority stakes in 8-10 other companies.
Yardstick, founded by Anand (founder of CB Insights), is a 90-day-old SaaS platform that charges enterprise software buyers $30-40k annually for researcher-conducted interviews with software vendors about pricing, satisfaction, and competitive positioning. The business inverts the typical review site model by charging buyers (not vendors) for verified data and positions itself as a high-value alternative to G2 Crowd by conducting original research rather than relying on unverified user reviews.
Kate (Amaranth) is the #1 creator on OnlyFans, earning $30M+ on the platform in just two years (April 2020 onwards). She built a sophisticated media empire with a 5-person core team plus extended staff, then expanded into Real Work—an agency offering virtual assistance services to other OnlyFans creators. Her growth was driven by leveraging an existing Twitch and Patreon audience, strategic use of earned media when her Instagram was banned, and continuous optimization of conversion tactics across multiple platforms.
Nikita Bier, who previously sold his viral high school app TBH to Facebook for $40-100 million, launched a new app called Crush designed to replicate that success with a monetization twist. The app uses a $6.99 weekly subscription ($28/month) model to reveal who voted for you in anonymous polls, and was geofenced to specific high schools in Georgia and Alabama. The app went viral within its targeted high school networks but faced controversy with rumors of misuse, leading to app store takedowns and rebranding efforts.
Orangewood Robotics is a hardware startup that trains general-purpose robotic arms to perform high-value industrial tasks like powder coating, painting, welding, and pick-and-pack operations. The company leverages affordable, programmable robotic arms (similar to how the iPhone became a platform) and writes specialized software to teach them different manufacturing processes. They rent their services to industrial clients for around $500/day, offering reliability and consistency that beats manual labor.
Only Problems is a subscription-based app pitched as 'OnlyFans for therapy' where subscribers pay monthly to observe real therapy sessions anonymously in a fly-on-the-wall format. Therapists receive subsidized or free sessions while gaining more clients, viewers get entertainment and secondhand therapeutic benefit, and the platform monetizes through a revenue-sharing model where users can tip therapists with hearts to influence payouts.
