What Damus does
Damus is a Vancouver-based private company (Damus Nostr Inc.) that builds the leading client application for the Nostr decentralized social networking protocol. Founded in 2022 by William Casarin, Damus provides censorship-resistant social media on iOS, Android, and Desktop, where users create accounts via cryptographic key pairs without phone number, email, or name registration. The product stack includes the core Damus client, the Damus Android variant (with a built-in AI assistant called Dave for search and summarization), and Notedeck, a native desktop application offering multi-column power-user views with planned Android and iOS support. The company's value proposition centers on user-owned identity, absence of manipulative engagement algorithms, no advertising, and integrated Bitcoin Lightning tipping ('zapping') for value-for-value creator monetization.
Damus monetizes primarily through Purple, a paid membership subscription priced at 8,250 sats/month or 82,500 sats/year (a 16% annual discount), payable via Lightning, fiat, or crypto. Purple members receive automatic translations, longer note storage, an early-access badge, and exclusive early access to Notedeck Alpha. A secondary merchandise store (caps and apparel) provides ancillary revenue. The company received $5 million from Jack Dorsey in 2023 for the underlying Nostr protocol, and operates with a small team of approximately 10-11 people. Geographic reach is global with one notable restriction: Damus was pulled from Apple's App Store in China in February 2023 after only two days.
The go-to-market motion is community-led through the Bitcoin/crypto ecosystem, open-source developer relations on GitHub, conference participation (four Bitcoin events in 2025), and earned media coverage (Forbes, TechCrunch, CoinDesk). Damus does not sell to enterprises; it serves individual consumers in three primary personas — Bitcoin/crypto enthusiasts, free-speech advocates, and privacy-conscious users — with no disclosed B2B or anchor customer contracts.
