What Clicksign does

Clicksign (legal entity Clicksign Gestão de Documentos S.A., CNPJ 12.499.520/0001-70) is a Brazilian electronic signature and digital document management platform founded in 2010 and headquartered in Barueri (São Paulo metropolitan area). The platform collects legally valid electronic signatures under Brazilian law (MP 2.200-2/2001 and Lei 14.063/2020), integrates with the ICP-Brasil digital certificate ecosystem, and offers 16 authentication methods including token via email/WhatsApp/SMS, facial biometrics, SERPRO government-database validation, PIX-based authentication, documentoscopy, and geolocation. The product suite is organized around core signature (Assinatura Eletrônica), Envelope (multi-document containers), Automação (template-based generation and mass sending), WhatsApp and Aceite via WhatsApp (messaging-native signing), Click.AI (AI-assisted document intelligence), Autenticações (identity verification), ClickFlow (unified data collection and signing), Signatário (a free signer area), and a public Document Validator. A REST API 3.0 with sandbox, webhooks, and White Label embedding extends the platform to developer customers.

The underlying architecture is cloud-native, hosted on AWS with infrastructure split between the United States and Brazil, and supports SSO via Google and Microsoft. Computer vision is used for forensic document analysis and biometric facial matching; natural language processing powers Click.AI summarization and title/message generation across three languages. The platform maintains 100% uptime over a 90-day disclosed window, sustains an API rate limit of 50 requests per 10 seconds per account, and retains signed document history for 10 years. Validation infrastructure includes a free public Document Validator that checks cryptographic hashes without requiring an account.

Clicksign monetizes via tiered SaaS subscriptions (Start R$39/month, Plus R$59/month, Automação R$85/month, each for 20 documents), premium authentication add-ons billed per use, a R$0.99 per send WhatsApp Aceite transaction fee, an enterprise Avançado tier with custom pricing and multi-year contracts for 300+ documents/month, and usage-based API billing per finalized document. Go-to-market combines product-led growth (a 14-15 day free trial with 30 document sends and no credit card required) with enterprise field sales for large accounts, an API-first channel for SaaS embedders, and reseller/iPaaS distribution via Pluga and HubSpot integrations. The company serves technology firms, financial services and fintechs, healthcare, HR, legal, education, real estate, and large enterprises across Brazil, with named customers including Itaú, Femsa, VTEX, Porto Seguro, Solfácil, Colégio Bandeirantes, Universidade Cruzeiro do Sul, Rock Content, and Cartos.
