Subrat Sagar — Co-Founder

First-generation entrepreneur with 17 years of setting up and scaling businesses from zero to significant revenue. Started in edtech. Built teams, defined strategic roadmaps, scaled web-based and e-learning products. Learned to spot growth bottlenecks before they become problems. Founded Cloudbird and took it through the full journey - startup to scale. Specialist in business operations, enterprise sales, and team building. The unglamorous stuff that actually makes companies work: process, accountability, go-to-market strategy. Now I've landed in voice AI as Co-Founder at Unpod AI. Here's what we're solving: Gen-Z hates phone calls. Millennials get anxious before them. But business still runs on conversations. Sales teams make 150 calls a day. Recruiters spend hours researching contacts. Support teams lose revenue from missed calls. We built "WordPress for Communication" - an open-source voice AI platform that lets developers build voice agents as easily as they build websites. Enterprise-grade SIP infrastructure. Sub-200ms latency. Half a million minutes processed monthly. MIT licensed and free to use. Why open source? Because 17 years taught me that the best ideas don't fail from lack of talent - they fail from lack of access. We built our own SIP trunking when established providers failed us. Now we're giving it away so developers can build without barriers. What drives me: Removing friction between ideas and execution. Building tools that democratize technology. Making communication less painful. Experience across: Business development, enterprise & institutional sales, team building, product strategy, B2B & B2C models, startup operations Still learning. Still building. Still solving problems. subrat@unpod.ai unpod.ai
