What is BharatMLStack?
BharatMLStack is a production-ready, cloud-agnostic ML infrastructure platform that powers real-time feature serving, model inference, and embedding search at massive scale. Built and battle-tested at Meesho, it is designed to help organizations ship ML to production faster, cheaper, and more reliably.
Our Vision
BharatMLStack is built around four core tenets:
Workflow Integration & Productivity
Ship ML to production faster than ever.
- 3x faster experiment-to-deployment cycles
- 95% reduction in model onboarding time
Cloud-Agnostic & Lock-In Free
Run anywhere. Own your stack.
- Runs across public cloud, on-prem, and edge
- Kubernetes-native with zero vendor lock-in
Economic Efficiency
Do more with less.
- 60–70% lower infrastructure costs vs hyperscaler managed services
- Optimized resource utilization across CPU and GPU workloads
Availability & Scalability
Enterprise-grade reliability at internet scale.
- 99.99% uptime across clusters
- 1M+ QPS with low latency
Designed Truly for Bharat Scale
Built for the demands of one of the world's largest e-commerce platforms:
