Oliver Silverstein is Co-Founder and CEO of OpenCall.ai, a Y Combinator-backed AI voice agent platform that helps businesses capture missed-call revenue and automate customer interactions at scale.
Oliver studied Computer Science at Northeastern University, then went on to streamline ARM's chip design processes using cloud technology and built an AI system to track student outcomes for Northeastern.
Oliver co-founded OpenCall alongside his brother Arthur Silverstein, Nicholas Lee, and Eric Mei, bringing together a team with deep expertise in AI, software engineering, and enterprise technology.
OpenCall was part of Y Combinator's Winter 2024 cohort and has raised $6M in funding, with investors including Y Combinator and CoreNest Capital, validating its position in the AI-driven customer service space.
OpenCall's AI agents help businesses cut call-handling costs by 50-80% and recover the 10-30% of revenue typically lost to call abandonment, serving industries from healthcare practices to service businesses nationwide.
