What Libellum Digital does

Libellum Digital (legal entity Ramos Digital Ltda, CNPJ 47.605.040/0001-20) is a Brazilian digital certification services provider headquartered in Formiga, Minas Gerais. The company issues ICP-Brasil-standard digital certificates — e-CNPJ and e-CPF in both A1 (file-based, 12-month validity) and A3 (token/smartcard-based, 36-month validity) formats, plus specialized NF-e and CT-e certificates — under the AC Soluti certificate authority chain. Differentiated features include remote issuance via video conference validation, an online certificate-testing utility, and downloadable driver/installer resources. The company is LGPD-compliant and operates its storefront through the GFSIS e-commerce platform.

The business model combines transactional revenue from initial certificate sales with recurring revenue from renewals (12- or 36-month cycles). Pricing is not publicly disclosed and is positioned as one-time/perpetual-license style purchase through the online portal. Libellum serves three primary segments: (i) Brazilian business entities of all sizes needing certificates for NF-e/CT-e issuance, e-CNPJ operations, and government portal access (Receita Federal, eSocial, SPED, FGTS); (ii) individual professionals and self-employed persons (accountants, lawyers, doctors, engineers, military personnel) needing e-CPF identity; and (iii) partner businesses — accounting networks, franchises, associations, and unions — that resell or refer certificates to end clients.

Go-to-market is executed through three channels: an owned e-commerce storefront for direct SMB/consumer sales, a no-cost partner/referral program targeting accountants and professional associations, and a physical unit in Formiga for in-person enterprise issuance. The company is small (7 employees), privately held with no disclosed outside funding, and was founded in 2023. Operating scope is currently domestic Brazil, focused on the Southeast region.
