Cero fills a genuine gap in LatAm healthcare automation with strong EMR integrations and WhatsApp-first design. Its pricing and exclusive focus on the region make it a niche but effective tool for medium-to-large providers. Limited free evaluation options and no transparent public pricing could be a barrier for small practices.

About Cero
PaidIntermediateAPI availableWeb · API
Cero is a LatAm-focused platform that automates communication between hospitals and patients. It replaces manual phone calls, WhatsApp chains, and spreadsheets with automated, configurable workflows. The system handles appointment reminders, pre- and post-consultation instructions, waiting list management, and satisfaction surveys via WhatsApp and voice calls. It's designed for clinics, hospitals, and healthcare providers across Brazil, Mexico, Colombia, Chile, Argentina, and Peru. Cero integrates with major EMR systems like Tasy, MV, Pixeon, and more, pulling data to trigger personalized messages. Its no-code workflow builder lets healthcare ops teams design journeys: for example, 'send reminder 24h before, confirm attendance, and collect feedback post-visit.' The platform supports both inbound (patient inquiries) and outbound (proactive notifications) communication. What makes Cero different is its deep focus on the Latin American healthcare market — it understands local infrastructure challenges (low SMS reliability, high WhatsApp penetration, regulatory requirements) and offers ready-made templates for common local workflows. It also provides analytics dashboards to track campaign performance, no-show rates, and response metrics. Pricing starts from $500/month for small clinics, scaling by patient volume. There's no free tier, but a demo is available. The platform is web-based and requires no installation.
Behind the Verdict
Cero is a well-tuned solution for its target market. Its deep integration with Latin American EMRs and focus on WhatsApp (the dominant messaging channel in the region) gives it an edge over generic communication platforms. For hospitals and large clinics in Brazil, Mexico, or Colombia that struggle with manual patient outreach, Cero can deliver quick ROI through reduced no-shows and lower administrative overhead. However, its narrow geographic scope and lack of a free tier limit its appeal. Organizations outside LatAm or those needing omnichannel (SMS, email, phone) support should look elsewhere. The absence of public pricing transparency may frustrate smaller buyers. Overall, Cero is a strong choice for mid-to-large healthcare providers in Latin America who want a purpose-built automation tool. It's less suitable for global enterprises or very small clinics.
