Buttondown is a minimal newsletter tool for writers and developers, offering clean subscriber management, Markdown editing, and a straightforward API without bloat.
Buttondown is an independent newsletter platform founded and operated by Justin Duke, designed as a minimal, well-crafted alternative to the feature complexity and opinionated workflows of larger newsletter and email marketing platforms for writers, developers, podcasters, and independent researchers who want a tool that stays out of their way and lets them focus on writing. Buttondown prioritizes correctness, transparency, and craftsmanship over feature accumulation — a positioning that has built a loyal following among technically discerning writers who value a codebase maintained by a single developer with clear values over the feature churn and pricing volatility associated with venture-backed platforms.
Tune is a partner marketing platform (formerly HasOffers) offering affiliate tracking, partner management, and mobile measurement for networks, agencies, and brands. Based in Seattle.
Tune, formerly HasOffers, is a Seattle-based partner marketing platform company that has provided affiliate tracking and performance marketing technology since 2009 — when it launched HasOffers as one of the first SaaS affiliate tracking platforms to serve the emerging performance marketing network market as an alternative to licensing expensive on-premise tracking software. The HasOffers platform became the foundation for hundreds of performance marketing networks, enabling entrepreneurs to launch professional affiliate operations without the prohibitive technology costs of building proprietary tracking infrastructure. The company rebranded to Tune in 2015 and expanded its platform to encompass mobile marketing measurement through the acquisition of MobileAppTracking (later TUNE Marketing Console), adding mobile app install attribution alongside its established web affiliate tracking capabilities.
