Buttondown
Simple newsletter tools for developers and writers.
A lean, developer-friendly newsletter platform that strips away the complexity of mainstream email marketing tools. Built as a solo side project starting in 2017, it grew through word-of-mouth among writers and developers who wanted clean, no-nonsense email sending with Markdown support and a minimal interface. The founder kept the product intentionally focused, avoiding feature bloat while steadily adding integrations and API access. Buttondown now generates $33k per month in recurring subscription revenue as a profitable one-person SaaS business.
