Inward is a breathwork app built by Robbie Bent, a former crypto investor and Ethereum community organizer who pivoted to wellness after making significant wealth in crypto. The app modernizes ancient breathwork techniques with guided sessions and music, designed to scale the in-person facilitated experiences that were booking out his Canadian garage 24/7. Early traction shows strong adoption with daily active users, positioning breathwork as the next major mental fitness category alongside SoulCycle and hot yoga.

Ramon acquired Alpha Paw, a dog ramp e-commerce business, for $300,000 and scaled it to $35 million in lifetime revenue.

DeSo is a blockchain infrastructure built from 2019-2021 that powers decentralized social networks. BitClap was the first prototype app launched in March 2021 with a viral growth mechanism of pre-populated user profiles and creator coins, achieving $80M in invested capital across the network despite only ~10,000-50,000 daily active users.

Circle is a white-labeled community platform built by three ex-Teachable employees (Andrew Guttormsen, Sid, and Rudy) who identified an unmet need: creators had tools to host content but not to build engaged communities. Starting as a side project in early 2020, they built an MVP in one month, grew a waiting list of thousands through a landing page and survey, and achieved #1 on Product Hunt at launch in August 2020—generating as much revenue in one month as in the prior six months combined. The company raised $5.5M and was adding hundreds of customers per month by December 2020.

Nick O'Hara quit his $130,000/year engineering job at Wayfair to build Canary, a mobile app connecting venues with musicians for booking live gigs.

Bunnyshell is a cloud management PaaS founded by Alin Dobra that automates provisioning, deployment, and infrastructure management across multiple cloud platforms. Launched in March 2018 with a 'sell-it-while-you-build-it' strategy using word-of-mouth and network outreach, the company secured €750K in funding and reached $12k/mo MRR by providing services to enterprise clients including pharma and eCommerce companies. The founders emphasize listening to customer feedback, focusing on specific use cases rather than broad feature sets, and building trust through partnerships with major cloud providers.

The bootstrapped SaaS grew organically over 4 years to €9,100/month MRR across 165 paying customers by leveraging content marketing and SEO, ranking on the first page of Google for key developer-focused keywords. 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. The company achieved traction through design award recognition, direct personal outreach, and strategic partnerships—notably with The Futur, which drove 30% revenue growth in one week and generated 29K YouTube views. Corebook now serves unicorn brands like Miro and GoPuff, growing 20% month-over-month.

BaseTemplates is a SaaS platform selling pitch deck templates, financial model templates, and custom pitch deck design services for startup founders. Founded in 2019 after acquisition, Maximilian Fleitmann grew the business from hundreds of dollars per month to over 5 figures monthly through content marketing, free tools, and strategic partnerships. The company has become a key resource in the founder and VC ecosystem without spending any money on traditional marketing.

Co-founders Thomas Jacquesson and Tibo grew the product from zero to $41K/month in roughly a year through organic launches, free side products, and a key partnership with Twitter growth expert JK Molina.

WePlate was a B2B SaaS nutrition platform that used an algorithm to recommend specific meals and portion sizes to college students and help universities optimize cafeteria menus. After 8 months of development and contacting nearly 100 universities, founder Alex Hu shut down the company when it became clear that colleges weren't interested in a product that didn't directly improve their bottom line, and students prioritized studying over diet optimization.

Observa was a security SaaS tool built by Rob Picard after leaving Robinhood to join Y Combinator in 2020. Over 10 months, Rob pivoted through three different product ideas (intrusion detection, botnet IP sharing, and public database exposure detection) but ultimately failed to achieve product-market fit, generating no revenue before shutting down in September 2021 after raising $462,000.

Benja Commerce Network was a gamified mobile shopping app and shoppable media ad network that helped define the interactive advertising space. After initial traction from a Product Hunt launch, Andrew pivoted to an ad network model with promising unit economics, but cash flow challenges and fundraising rejection led him to make material financial misrepresentations to investors, ultimately resulting in SEC/FBI investigation, shutdown, and his conviction for securities fraud in 2020.

DenberTech was a cryptocurrency payment processing platform founded by 20-year-old Dennis Ramírez Bernal in January 2022, born from the viral success of a Bitcoin-enabled Christmas cake campaign. Despite initial strong interest and leads from the campaign, the startup failed to achieve product-market fit because the market's enthusiasm for crypto payments was driven by hype rather than a genuine business problem. The company never achieved revenue and was shut down after spending approximately $5,000 primarily on customer acquisition through paid ads, with the founder learning a critical lesson about solving real problems rather than chasing trends.
