SaaS Startups

Spark Toro is a market research and audience intelligence SaaS tool founded by Rand Fishkin after leaving Moz. Launched in early 2020 amid COVID-19, the company raised $1.3M from angel investors through a unique profit-sharing structure designed for long-term sustainability rather than venture growth. Rand employed content-marketing-driven customer acquisition, blogging extensively about coronavirus, marketing strategy, and audience research to build awareness and credibility.

Course Hero is an online learning platform with 20 million registered students that helps students graduate through shared study resources and peer support. VP of Growth Tomas Pueyo applies storytelling principles and problem-solution frameworks to drive product and growth strategy, famously gaining recognition for his viral Medium article on coronavirus that reached 40-50 million views in the first week by using compelling narrative structure and authentic messaging.

Bram Kahnstein created No Code MVP, a course teaching entrepreneurs how to build and validate startup ideas without coding. After validating the concept with 2,800 BetaList subscribers and delivering corporate workshops (generating ~$20k), he launched the course with $4-5k in monthly revenue. The course teaches mindset, lean startup methodology, and practical no-code tools (Carrd, Zapier, AirTable) to help founders move from idea to validated MVP in small, testable steps.

Close is a CRM tool helping small and medium-sized businesses close more deals and communicate better, founded by Steli Efti. The company has grown to 45 people across 14 countries and is profitable, though exact revenue figures are not disclosed in this interview. Steli emphasizes building a sustainable company focused on serving entrepreneurial customers rather than chasing enterprise deals, prioritizing long-term relationships and maintaining a workplace culture that fosters both professional growth and personal fulfillment.

Scott's Cheap Flights is a paid newsletter business that alerts subscribers to cheap flight deals from their home airports. Starting in 2013 as a side project sharing deals with friends, it grew to 600,000 subscribers and $4 million in annual revenue by 2020. The business survived the COVID-19 pandemic better than most travel companies due to its annual subscription model, high margins, and bootstrap profitability.

Jonathan Little is a professional poker player who built pokercoaching.com into a $1.8M ARR business teaching poker strategy through memberships, books, YouTube, and podcasts. Starting as a community passion project that lost $5,000/month for 8 years, the business took off when a marketer named Dan helped sell instructional videos online. Little's success comes from his authentic expertise in poker, prolific content production (9am-6pm daily work ethic), strategic distribution across multiple channels, and a focus on genuinely helping recreational players improve—creating alignment between his passion, skill, and revenue.

JustReachOut.io is a SaaS platform that helps founders get press coverage by connecting them with journalists, providing journalist databases, and teaching them how to pitch stories that media actually wants. Dmitri Dragilev has grown the business to $30k MRR primarily through SEO by ranking for terms like 'media pitch' and 'PR outreach', demonstrating that consistent, targeted PR efforts compound better than chasing viral moments.

CoderPad is a browser-based code execution platform for technical interviews that Vincent Wu bootstrapped to millions in revenue before selling it to a private equity firm for tens of millions of dollars. After the sale, Wu has pursued investigative journalism, including exposing issues at Lambda School, while reflecting on entrepreneurship, wealth, and what success actually means.

Premek Hoyetski built Contentize, an AI-powered content generation SaaS platform, after two failed startups taught him the value of execution speed and solo founder confidence. Launched in January 2020 with a simple MVP built in 2 months with a Python developer, the platform reached 100 users initially. After a redesign completed in June 2020, it experienced significant growth. By nine months in (roughly September 2020), Contentize was generating between $4,000-$5,000 per month (primarily from advertising and affiliate revenue on generated content, with smaller SaaS subscription revenue), demonstrating that indie hackers could leverage AI tools and remote contractors to build sophisticated products without massive capital or teams.

Streak is a Chrome extension that integrates CRM functionality directly into Gmail, allowing users to manage sales and business workflows without leaving their inbox. Founded by Aleem Mawani in 2012 after pivoting from a failed loyalty rewards startup during Y Combinator, Streak grew profitably through word-of-mouth adoption by YC founders and early users who discovered it on the Chrome Web Store. By 2020, the company had reached millions in annual revenue with 30 employees, choosing to remain bootstrapped and profitable rather than pursuing venture funding.

Raskyoli is a wine bar and restaurant in Rome founded by Alessandro Pepe that expanded into a wine club and online educational platform (Community.wine) during the pandemic.

The business focuses on teaching wine appreciation through storytelling and cultural context rather than technical sommelier training.

Founded by Tara Reid in 2019, the company has grown to $5M ARR by charging $1,900 per student for an 8-week program with lifetime access.

Chris Oliver built GoRails starting in 2014 as a successor to the dormant Railscasts, offering weekly screencasts teaching advanced Ruby on Rails topics. He bootstrapped from zero to over $1 million in total revenue by combining free educational content (blog posts, videos, community forums) with paid products including a subscription screencast service ($20/month), courses, app templates, and Hatchbox (a Rails deployment automation tool).

Dave Geddes quit his high-paying job at Domo to pursue his passion for creating educational games. He built Flexbox Zombies as a free game that grew to 70,000 subscribers through word-of-mouth and remarkable design, then launched Grid Critters at $99-$229, making $30,000 on day one of pre-orders. He's now full-time for 4+ years, building a suite of coding education games through interactive gameplay rather than traditional tutorials.

Kevin Lee, formerly a venture capitalist and product manager at Facebook, left tech to co-found ME (Imi), a low-carb, high-protein instant ramen company.

Derek Reimer launched Savi Cal, a scheduling tool competing directly with Calendly, around the pandemic onset. After a failed attempt with Level (an anti-Slack communication tool), Derek applied rigorous lessons about founder-market fit and built Savi Cal to address the friction and etiquette issues surrounding scheduling links. The product reached $10K MRR by leveraging Derek's existing audience from his podcast and public presence.

Interviewed was a non-technical hiring assessment platform founded in March 2015 by Chris Bucky and co-founders who met at 42 Floors. Starting from a hackathon prototype, they grew to $2.5M ARR in 2.5 years by targeting high-budget HR tech spending and strategically taking early bets on fast-growing startups like DoorDash, Canva, and Taskus that would scale their usage over time. The company was acquired by Indeed for approximately $50 million.

Andre Azumov, a Ukrainian founder living in Bali on $400/month, quit his job to spend a year building multiple projects.
