What Assinei does
Assinei Digital Ltda. is a Brazilian legaltech SaaS company founded in 2019 in Goiânia, GO, operating as a startup subsidiary of Aliare within the Siagri Group ecosystem. It delivers electronic and digital signature, contract lifecycle management, and cloud-based document storage services to Brazilian businesses, with a primary vertical focus on agribusiness — including agricultural credit instruments (CPRs, Cédula de Produto Rural), agronomic prescriptions, and rural supply chain documentation. The platform has on-boarded over 100,000 users (per the company's own marketing) and supports both electronic signatures (validated under MP 2.200-2/01) and digital signatures using ICP-Brasil certified certificates, ensuring legally valid signatures under Brazilian law and compliance with Lei 14.063/2020 and LGPD.
The core product is a unified SaaS platform accessible at app.assinei.digital, with modules including Document & Contract Management (vault-based organization, templates, versioning), Gestão Digital de CPRs (Rural Product Note digital management), Canhoto Digital (mobile offline-capable delivery receipt signature), Assinei Conecta (REST API integration via OAuth2 with Document, Vault, Participants, Webhook, and Identity endpoints), and a public Document Validator. Underlying infrastructure runs on Microsoft Azure and uses HASH SHA 256 cryptographic integrity plus OAuth2-based Aliare Identity authentication. Native integration with Siagri ERP systems enables automated document flows for agricultural prescription issuance, billing, and receituário agronômico workflows.
Assinei operates a subscription-based SaaS revenue model with freemium acquisition (free trial accounts and free signing for recipients) and quote-based paid plan tiers differentiated by document volume and user seats. Pricing is not publicly disclosed. Go-to-market combines product-led growth via self-serve signup, enterprise demo-request sales motion for larger agribusiness clients, and a developer/API-first channel targeting software integrators. Distribution is augmented through the Aliare/Siagri partner channel into Brazil's installed agribusiness ERP base. The company has a lean team of approximately 9 employees, no disclosed outside funding, and is wholly owned by Siagri Sistemas de Gestão Ltda. via Aliare.
