Cero
Automate patient communication and hospital workflows across Latin America.
Cero fills a genuine gap in LatAm healthcare automation with strong EMR integrations and a WhatsApp-first design. If you're a mid-to-large clinic or hospital in Brazil, Mexico, or Colombia, it's a solid choice to cut no-shows and streamline patient communication. But the $500/month entry price and regional lock-in make it a poor fit for small practices or anyone outside LatAm. For North American teams, look at solutions like Solutionreach or Luma Health instead.

Skip Cero if you're a small clinic in LatAm with under 500 monthly appointments or if you operate outside Latin America — the $500/month entry price and regional lock-in make it a poor fit.
Going past your plan's patient volume (e.g., 1,500 on Starter) may require a plan upgrade, potentially doubling your monthly cost.
Cero's $500/month entry price suits mid-to-large clinics and hospitals in LatAm with high patient volume, while smaller practices may find cheaper alternatives like simple WhatsApp scheduling tools or manual reminders. In the North American market, peers like Solutionreach offer similar features but at scale, making Cero a regional value play.
In short
Cero — Automate patient communication and hospital workflows across Latin America. Best for Hospital operations managers in LatAm, Clinic administrators looking to reduce no-shows, Healthcare providers with high patient volumes. Plans from $500/mo.

About Cero
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 others, 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 stands out in the Latin American healthcare market by focusing specifically on the communication pain points that plague clinics and hospitals there. Its deep integration with regional EMRs like Tasy and MV means you can pull patient data directly to trigger automated WhatsApp reminders, which is a huge time-saver for ops teams that previously relied on spreadsheets and phone calls. The no-code workflow builder is flexible enough to design complex patient journeys, from pre-consultation intake to post-visit satisfaction surveys, all through WhatsApp and voice calls. However, the platform's regional focus is also its biggest limitation. If you're not operating in one of the supported countries (Brazil, Mexico, Colombia, Chile, Argentina, Peru), Cero simply won't be useful. The $500/month entry price is steep for small clinics with under 500 appointments per month, and there's no free tier to test the waters before committing. Additionally, since it's WhatsApp-first, you'll need to navigate WhatsApp Business API rates and approval processes, which can add complexity. For mid-to-large clinics and hospitals in LatAm that want to reduce no-shows and automate patient communication, Cero is a strong, purpose-built option. But if you're a solo practitioner or a small clinic, you'd be better served by cheaper, more general-purpose scheduling tools with WhatsApp integration, or even a simple reminder SMS service. For organizations outside LatAm, Cero should be off your radar entirely — opt for region-appropriate solutions like Solutionreach or Luma Health.
