What Cero.AI does

Cero.AI (legal entity BOTLAB SpA) is a Chile-based B2B SaaS company that automates communication between healthcare institutions and patients via WhatsApp and messaging channels. Founded in 2017 and headquartered in Santiago, the company serves hospitals, clinics, dental practices, and healthcare networks primarily in Chile and Colombia, with an installed base of more than 250 health centers coordinating over one million appointments per month.

The core product is an AI-powered conversational platform that handles the full appointment lifecycle: confirmations, multiple confirmations, spontaneous cancellations, automatic rescheduling, waitlist management, agenda blocking, referrals, and preventive care outreach. The system uses natural language processing tuned for colloquial Spanish, including emojis, spelling variations, and gender-correct honorifics. It is built on a deep integration layer that connects to 16 regional healthcare scheduling and CRM systems, including clFlow, Intersystems, Dentalink, AgendaPro, Rayen Salud, and iMedical. The company is a Y Combinator alumnus and was founded by Luis Felipe Rodríguez Besa (CEO), Jorge Perez, and Mauricio Quezada (CTO).

Cero.AI operates a sales-led B2B model, contracting individually with each healthcare institution through custom proposals and multi-year subscriptions. Pricing is quote-based and not publicly disclosed. The company generates recurring subscription revenue and has reported outcomes of 90%+ patient communication reach at a fraction of the cost of a call center. Total disclosed venture funding to date is a $125,000 seed round in August 2021 led by Y Combinator with participation from AAF Management and Crossbeam Venture Partners, supplemented by support from Start-Up Chile (SUP Chile).
