Voice-AI startup Synthio Labs has raised US$ 5 million in a seed funding round led by Elevation Capital, with participation from 1984 Ventures, Peak XV Partners, Y Combinator, and several angel investors from the global AI and healthcare ecosystem.

The company plans to use the funds to scale up its engineering and product teams, expand deployments in the U.S. and Europe, and deepen partnerships with life-sciences firms. 

Synthio Labs builds a clinical-grade voice-AI “operating system” tailored for life-sciences engagement. Its platform is composed of three core products: Jarvis, a voice-AI copilot for field teams; Ather, a multimodal engine for seamless engagement between physicians and patients; and Simulation Studio, which creates high-fidelity digital twins of clinicians and patients for research and strategic insights. 

The startup aims to solve a long-standing problem in pharma: fragmented and manual communication with clinicians and patients. By automating compliant, real-time conversations and delivering structured intelligence at scale, Synthio’s tools promise to improve engagement quality and operational efficiency for life-sciences teams.

Founded by Supreet Deshpande (CEO), Rajashekar Vasantha (CTO), and Sahitya Sridhar (CPO), Synthio Labs is already working with top pharmaceutical companies and digital healthcare brands. In one notable use-case, its voice-AI solution handled over 5,000 calls to eczema patients in 48 hours, supporting onboarding, screening, and patient assistance.
