The team of 9 (mostly part-time across Europe) reached near break-even without external investment, proving a niche B2D product can succeed through organic growth and direct customer engagement.

Corebook is a collaborative online brand guidelines platform founded by Janis Verzemnieks to replace static PDF brand guidelines.

Observa was a security SaaS tool built by Rob Picard after leaving Robinhood to join Y Combinator in 2020.

PubLoft was a marketplace connecting writers with companies seeking managed blog services at $2,000/month subscription. Mat Sherman grew it from $0 to $24K MRR in 7 months using cold email outreach and personal sales, securing a $100K investment from Jason Calacanis.

The agency started with minimum $10k/month contracts for custom SEO, PPC, email marketing, and CRO work.

Collin Kartchner and Samir Chaudry launched the Lacrosse Network in 2011 as a YouTube channel aggregating lacrosse content.

Today, they run the "Collin and Samir" YouTube channel with 813K subscribers, a seven-figure advertising-based business, and an accompanying newsletter, focusing on creator economy content and interviews.

Starting in 2014 while traveling, he built Nomad List, Remote.ok, and other niche products targeting remote workers and digital nomads.

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.

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.

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.
