Noko (formerly Freckle)by Amy Hoy
Noko is a time-tracking SaaS product built by Amy Hoy during the 2008 recession. Launched with $1,500 MRR from her existing audience of developers, it grew primarily through word-of-mouth and reputation rather than paid marketing. After years of being largely neglected due to Amy's health issues, Noko has maintained steady revenue of over $500K ARR by focusing on solving a real problem (helping consultants bill accurately and track profitability) for a willing-to-pay audience.
