What Closum does
Closum is an omnichannel marketing automation SaaS platform targeted at B2C brands, operated by Portuguese private limited company DRIBLE, LDA. (NIF 513543244) and headquartered in Vila Nova de Famalicão, Portugal. The platform centralises customer communication across Email, SMS, WhatsApp, Telegram, WebPush, RCS, and forms within a single unified customer profile, and is sold under three pricing tiers — Zero (free), Growth (€12/month), and Advanced (€35/month) — with a 20% annual discount and a 15-day no-credit-card trial. Adjacent revenue streams include pre-paid SMS credit bundles (1,000-75,000 SMS, no expiry), pay-per-conversation WhatsApp Business API access, and WebPush notification bundles, creating a hybrid subscription plus usage-based monetisation model.
The platform is built on a no-code drag-and-drop architecture covering email, landing pages, pop-ups, and multi-step automations, complemented by an AI Assistant integrated with OpenAI for generative message creation. It exposes a REST API and webhooks for technical teams, supports an SMTP service for transactional send, and integrates with over 600 third-party applications including Salesforce, Shopify, WooCommerce, Stripe, PayPal, Pipedrive, ClickUp, Typeform, Calendly, and Hotmart. The company has accumulated ISO/IEC 27001, ISO/IEC 42001:2023, SOC 2 Type II (2025-2026), SOC 3 (2025-2026) certifications and a GDPR compliance programme, and reports more than 2,500 customer companies across enterprise and SMB segments, including Decathlon, Fnac, Recheio, Remax, Era, Job&Talent, Boomfit, and Swonkie.
Go-to-market is anchored on a product-led growth motion with self-serve registration at app.closum.com, supported by a certified partner directory, an affiliate programme paying up to 30% recurring commissions, and a hybrid sales-assisted 'Request demo' path for larger deals. The business operates across 30+ countries with SMS coverage spanning Western Europe, Lusophone Africa, and Brazil, and is bootstrapped with no disclosed external funding, no parent company, and no M&A history. The company has been operating under the Closum brand since 2017 (DRIBLE, LDA. since 2015) and is hiring for a Client Manager, PHP Programmer, and Marketing Intern, indicating modest but ongoing organisational expansion.
