AI voice agents that automate your inbound support calls
Built by the engineer behind Battery Smart's production voice agent — handling driver support at scale for India's largest EV battery-swapping network.
The Founder
Led by the founding engineer who built Battery Smart's tech — seed to a $340M valuation.
We were among the first tech team members at Battery Smart — India's largest EV battery-swapping network, now backed by 20 institutional investors including Tiger Global Management and Orios Venture Partners, with the company's tech carrying it to a net valuation of $340 million.
Being that early means wearing every hat a developer in a big team never has to. We set up the entire frontend, backend, database, and DevOps infrastructure — shipping 3 customer-facing apps and 6 backend services, owning IoT data ingestion built to store and serve telemetry from 1M+ devices without stressing the database under large concurrent loads, and building the production Hindi voice agent that answers Battery Smart's driver support calls today.
Since September 2023, we've been building Aesphire Technologies — an AI services and business consultancy firm working on LLM model development and MLOps.
Aesphire is where that depth goes to work for you: AI voice agents that automate inbound support calls, on full-stack engineering that holds up in production — shipped end to end, from system design to deployment.
