"Before Synthesys, our team was drowning in inbound calls and missed follow-ups. Within the first month, we cut response times by 70% and saved almost $30K in payroll. Customers now tell us we feel like a much bigger company than we actually are."
Rachel Kim, COO, MedFlow HealthTech
“Scaling outbound calls used to mean hiring more reps, which killed margins. With Synthesys, we’re handling thousands of calls automatically every week and closing deals at 2x our old pace. It feels like we unlocked an unfair advantage.”
Daniel Ortiz, Founder & CEO, FreightLink Logistics
