Quatro Cinco Um

What Quatro Cinco Um does

Quatro Cinco Um (Associação Quatro Cinco Um) is a São Paulo-based independent Brazilian literary publication organized as a non-profit association, founded in 2017. The company produces a monthly print magazine with 107 published editions as of July 2026, accompanied by a digital edition with fac-simile reproduction, a long-running podcast (451 MHz, 200+ episodes since July 2019), the Bagagem Literária news and events portal, an annual literary festival (A Feira do Livro, 93,000 visitors in 2026), and a wholly-owned book publishing imprint (Tinta-da-China Brasil). Its editorial coverage spans literary criticism, fiction, poetry, social sciences, politics, and LGBTQIA+ themes, with dedicated sections produced through institutional partnerships with Japan House São Paulo (Japanese literature since 2019), LAUT (democracy and authoritarianism since 2020), and Jornal Público of Portugal (binational reading club). The technology stack is a WordPress-based CMS with self-serve subscription management and e-commerce, hosting digital fac-simile editions, subscriber accounts, and the Clube de Benefícios 451 discount platform integrated with 40+ publisher and cultural partners.

The company operates a subscription-driven business model with nine public pricing tiers ranging from R$99/year (Sub-26 youth) to R$1,332/year (Assinante Entusiasta), including digital-only, print+digital, podcast supporter, book-club (Clube 451), and international digital plans. Primary revenue streams are recurring digital and print+digital subscriptions sold directly via the website, supplemented by one-time newsstand sales distributed through Folha de S.Paulo channels to nearly 200 Brazilian cities and Livraria da Travessa in Lisbon. Enthusiast and Clube 451 tiers provide higher-ARPU supporter revenue with recognition benefits. Ancillary monetization includes festival sponsorship (Ministério da Cultura as presenting sponsor of A Feira do Livro) and the Clube de Benefícios cross-promotion network. The customer base is entirely B2C, serving literary enthusiasts and cultural institution patrons across Brazil with a small international extension via Lisbon retail and international digital subscriptions. No funding rounds, no public revenue disclosure, and no AI/ML capabilities are referenced in available data.
