What Grupo Certmais does

Grupo Certmais (legal entity: Certmais Soluções Empresariais e Certificação Digital LTDA, CNPJ 31.014.048/0001-82) is a private Brazilian limited-liability company headquartered in Natal, Rio Grande do Norte, that operates as a Registring Authority (Autoridade de Registro, AR) within the ICP-Brasil public-key infrastructure — the regulated framework for digital certification in Brazil overseen by the Instituto Nacional de Tecnologia da Informação (ITI). It is linked to multiple Certifying Authorities (Autoridades Certificadoras), specifically SAFEWEB CD, DIGITAL CERTY, and SAFEWEB RFB, allowing it to issue compliant digital certificates (e-CPF, e-CNPJ, NF-e related) to individuals and legal entities.

The company's product portfolio extends beyond pure certificate issuance into a bundled suite of SMB-facing services: DocMais (electronic document signing), Certmais Web / Certmais Sistemas (fiscal and accounting automation software), Certmarcas (trademark registration services), CertSolar (solar energy hardware and installation), and Certmais Conversas. Underlying technology centers on PKI-based digital identity, plus adjacent workflow automation for fiscal compliance and Brazilian tax regimes (likely SPED, NF-e, and related obligations given Certmais Web positioning). No proprietary AI/ML capabilities, patents, or research programs are evident; the stack appears conventional and dependent on the linked ACs for the cryptographic backbone.

Commercially, Grupo Certmais combines recurring revenue (annual certificate renewals, software subscriptions) with transactional revenue (trademark filings) and project-based revenue (solar installations). Go-to-market is sales-led and channel-diversified: direct WhatsApp-based selling, e-commerce checkout on company properties, a structured partner/reseller program ('Seja parceiro'), and brand presence on Instagram (@certmais). It serves a fragmented base of individual professionals and SMBs across Brazil, with claimed nationwide reach from its Natal headquarters. The company is small (~20 employees) with no disclosed funding rounds, acquisitions, M&A activity, or executive leadership visibility in the public input.

Core offering

Grupo Certmais is a Brazilian digital certification and business solutions provider that issues regulated digital certificates (e-CPF for individuals and e-CNPJ for businesses) and offers complementary software, trademark registration, and solar energy services. Its core revenue comes from digital certificate issuance/renewal and SaaS-style subscriptions to its Certmais Web fiscal automation and DocMais electronic signature platforms, all delivered through its own e-commerce storefront, WhatsApp sales motion, and partner referral network.

Product overview

Grupo Certmais operates as a digital certification and business solutions provider offering a portfolio of interconnected products centered on digital trust infrastructure. The core offering is its digital certificate service (Certificado Digital) providing e-CPF and e-CNPJ for identity verification and electronic signing. This is complemented by DocMais, a document signing add-on that leverages the certificates to enable legally valid digital signatures with timestamp certification. The Certmais Sistemas (Certmais Web) module extends the platform into fiscal automation by automating invoice issuance and financial management. The company also diversifies into adjacent verticals: Certmarcas for trademark registration and CertSolar for solar photovoltaic energy solutions, alongside a messaging tool called Certmais Conversas.

Scale indicators2 records

Recent moves5 records

Expansion highlights5 records

Broad incumbents

• Certisign: One of Brazil's largest digital certification authorities, offering e-CPF, e-CNPJ, and digital signing services nationwide. Directly comparable to Certmais as a competing AR/AC, but with significantly greater scale, brand recognition, and enterprise customer penetration.
• TOTVS: Brazil's largest enterprise software company, with fiscal automation, ERP, and financial management offerings that overlap with Certmais Web/Certmais Sistemas. As a broad incumbent, TOTVS competes for the same SMB fiscal-automation wallet with substantially greater scale and product breadth.
• Serpro (Serviço Federal de Processamento de Dados): Brazilian federal data processing service that operates its own certification authority and provides infrastructure for government certificate issuance. A broad incumbent and partner (Certmais hosts Serpro installer links), competing for the same e-CNPJ/e-CPF demand with the advantage of direct government affiliation.
• Valid Certificadora (Valid): Major Brazilian digital identity and certification company providing e-CPF, e-CNPJ, NFC-e, and related secure transaction services. A broad incumbent competitor to Certmais, with substantially larger scale, multi-product identity offerings, and national brand presence.

Direct peers

• Soluti: Brazilian digital certification authority operating its own AC and AR network under ICP-Brasil, serving individuals and businesses with e-CPF, e-CNPJ, and digital signing. Closely comparable to Certmais in product offering and target market, with greater scale and geographic reach.
• BRy Tecnologia: Brazilian technology company providing digital certification, electronic signature, and timestamping solutions to enterprises and government. Comparable to Certmais's DocMais signing offering and timestamp server, with a stronger enterprise/government focus.
• AC Digital Certy: Brazilian certification authority that Certmais is linked to as an AR. Competes in the same e-CPF/e-CNPJ issuance market and serves as both a partner and competitive benchmark for Certmais's go-to-market in Northeastern Brazil.
• Safeweb Segurança da Informação: Brazilian certification authority that is also a key partner of Certmais (Certmais acts as an AR linked to AC SAFEWEB). Safeweb issues certificates under ICP-Brasil and competes in the same SMB/individual segment; the dual partner/competitor dynamic is directly relevant to Certmais's economics.

Emerging players

• Conta Azul: Brazilian SaaS platform providing financial management, invoicing, and tax automation for SMBs and service-based companies, directly overlapping with Certmais Web's fiscal document and financial control use cases. Focused emerging player with stronger digital brand and software velocity.
• Portal Solar: Brazilian solar energy marketplace and installation services company, comparable to Certmais's CertSolar vertical. An emerging player with greater geographic coverage and a marketplace model that Certmais would have to scale to match.
