Synthesys gives your startup everything you need to run sales and support at scale—24/7 multilingual calling, smart routing, instant follow-ups, and deep integration with your existing tools—all in one place.
A single platform for your startup
From day one, Synthesys helps you capture every opportunity without drowning in admin work. Whether you’re pre-seed or post-Series B, our AI telecommunications platform integrates directly into your CRM, calendar, and tech stack to give you full control over sales, service, and customer success. And it grows with you at every stage.
Cut burn, not corners
Every missed call is lost revenue. Synthesys eliminates that waste by replacing slow, costly human processes with real-time AI calling that scales instantly. With automated lead follow-up, payment recovery, appointment scheduling, and more, you’ll reduce costs while increasing conversions—unlocking faster growth without adding payroll.
No personal guarantees, built for founders

Saves you time so you can build
Let Synthesys handle the outbound, inbound, and follow-up work while you focus on growing your company. Set the right routing rules and controls, and our AI will engage every prospect, lead, or customer in real time—without you lifting a finger.
Close your books on time, every time
With Synthesys call logs, recordings, and analytics automatically synced to your CRM and reporting tools, you’ll have complete visibility into every interaction. No messy spreadsheets, no missing data—just instant insight into what’s driving results.
Control spend before it happens
By automating outreach and customer service, you can predict and control your labor costs while avoiding overstaffing. Scale communications capacity instantly during peak demand without ballooning your monthly burn.

"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
