Every Missed Call Is Lost Revenue

The average restaurant receives 75 calls per day, and 25% go unanswered — translating to up to $100K per year in lost revenue per location. Staff juggle in-person customers, kitchen coordination, and a ringing phone that never stops. Certus AI saw this as the single biggest operational bottleneck in the restaurant industry.

What They're Building

Certus AI replaces the restaurant phone line with an intelligent voice AI that answers every call 24/7 — taking orders, processing deliveries, booking reservations, upselling, and handling complaints in English, Spanish, and French. The system integrates with Toast, Square, Clover, UberEats, and DoorDash, and offers Raspberry Pi hardware for receipt printing directly in the kitchen.

With 98.6% order accuracy and $660K in revenue from a lean 6-person team, Certus AI is proving that voice AI can outperform human phone operators. Customers save $9K+ per month, some see a 3x increase in delivery revenue, and staff save 45% of their phone time to focus on in-house guests.

Growth

Certus AI raised a $500K seed round and was accepted into Y Combinator's Summer 2025 batch. The company is rapidly expanding across restaurant chains, delivering measurable ROI from day one. As an African-founded venture in YC S25, Certus AI represents a new wave of global founders tackling trillion-dollar industries with AI-first solutions.
