Sintra offers a platform of AI-powered helpers (agents) that integrate with tools like Facebook, Gmail and Google Calendar to perform social media, support and admin work. The product runs on a shared context layer called Brainy AI, a vector-database layer that stores business context and enables increasingly autonomous agent actions. Founded just over a year ago and built in Lithuania, Sintra scaled rapidly from a viral weekend product to a $12 million ARR business serving over 40,000 paying customers in 100+ countries. The company relaunched Sintra 2.0 on May 15, 2024; its most popular agent to date is “Soci” for social media. Pricing starts at $39/month. The team says it will focus on three core vectors—context, agent tooling, and simplification—and will use the new capital to expand product and engineering teams.
