Garrett Diamond built Sifter, a bug tracking SaaS for small teams that prioritized simplicity and non-technical user adoption over feature richness. Launched in 2008 after 6 months of development, Sifter grew through word-of-mouth and targeted advertising (notably a $2,500 Daring Fireball ad that brought 30-35 customers). The business generated healthy recurring revenue over 8 years and sold for low six figures in part because recurring revenue allowed Garrett to maintain the business through significant health challenges.

Josh Pigford built Bear Metrics in just 7-8 days in November 2013 to solve his own pain point: tracking key SaaS metrics from Stripe data.

By 2017, Bear Metrics had reached $70k MRR through a combination of strategic partnerships (like Buffer), transparency (public dashboards), and content marketing, while raising $800k from the Stripe Platform Fund.

This is a deep-dive interview/discussion between Cortlin from ndhackers.com and Clifford Ortevac, founder of Tambu and author of "The Epic Guide to Bootstrapping a SaaS Startup from Scratch by Yourself." Rather than focusing on Tambu's specific metrics, the conversation explores the philosophical and practical foundations of indie hacking—why developers should consider building products independently, why SaaS is harder than alternatives like info products or WordPress plugins, and what realistic expectations and skills aspiring founders need to succeed.

Moritz Dousinger built MailParser as a side project while working full-time as a consultant, launching a minimal prototype on Hacker News that generated 11,000 page views but zero customers initially.
