Minus is a small, experimental social network that allows each user exactly 100 posts for life, with every new post reducing a visible countdown of remaining posts; replies are allowed but do not consume the lifetime total. The service offers a reverse‑chronological, non‑algorithmic feed with vague timestamps, no likes, follows, or monetization, and no visible engagement metrics other than the post‑countdown. It is used by a niche community of reflective, often multilingual users who treat the 100‑post constraint as a prompt for more deliberate writing and conversation. The platform is built and maintained by artist and professor Ben Grosser, who created Minus as part of his solo exhibition *Software for Less* commissioned by arebyte Gallery in London. No external fundraising rounds, venture‑style investment, or corporate‑scale financing are documented for this version of Minus; it operates as a non‑commercial art project rather than a funded startup. The project is associated with arebyte Gallery in London, but no formal corporate headquarters or additional offices are specified for Minus itself.
