Challenge
“Only the lead engineers were managing all production issues.”
Suman Varanasi, Co-Founder & CTO
“It was hard for us to debug because we had to go to multiple places.”
Ashish Gupta, Principal Software Engineer
Fello's hyper-efficient team hit a scaling wall. Despite generating massive revenue per engineer, their observability chaos was holding them back.
Pain Points:
Knowledge silos: Only lead engineers could debug production
Tool sprawl: Hard to debug across CloudWatch, Prometheus & Grafana
Cost spiral: High CloudWatch bills with pay-per-query penalties
Failed cost-saving attempts: CloudWatch infrequent tier created more friction
Maintenance burden: Frequent scaling issues with Prometheus servers
Solution
Why Fello Chose the Underdog
“I wanted to find the right team who are constantly pushing the boundary and thinking about that problem all the time.”
Suman Varanasi, Co-Founder & CTO
“This is cheaper in terms of storage and ingestion everything. And it is using the private endpoint so there is no extra network cost either.”
Vinay Krishna, Senior DevOps Engineer
Fello bet on innovation. They found a startup that obsessed over observability the way they obsessed over efficiency.
What made the difference:
Fully managed: No maintenance overhead, no scaling headaches
Cost-efficient: 50% cheaper, S3 backend architecture, affordable 90+ day retention
Unified & Intuitive UX: Easily find what you need to debug in one place
AI-powered: Anomaly detection that competitors couldn't match
Easy Migration: Onboarding completed within hours
Team responsiveness: PagerDuty integration “pulled off within a couple of days”
Impact
Focus on Business, Not Observability
Ashish Gupta, Principal Software Engineer, shares his experience with team adoption and productivity gains:
“It has been very seamless, we don't need to worry about observability anymore. We focus primarily on our business now.”
“They love it now. It's a one-stop platform for all observability.”
Every engineer now rotates through on-call confidently. Someone who doesn't have knowledge of query language can also query logs by just adding filters in the UI. Costs dropped 50% while capabilities expanded dramatically.
