Shailendra Singh : Building The Safety Net Modern Software Never Had
Shailendra Singh
Founder & CEO
The bug was invisible to code review. No static analysis tool would have caught it. But HyperTest saw it because it doesn't just read code, it runs it.
This is the kind of problem Shailendra Singh has spent his career thinking about: The bugs that slip through because teams are moving fast and testing is an after thought.
The Problem He Couldn't Stop Seeing
Shailendra spent a decade building products at startups, most recently at OYO Rooms. He saw the same pattern every where: teams shipping fast, skipping proper testing, and hoping nothing breaks.
“You’d watch features go out and just wait for something to go wrong,” he says. “Payment failures. Duplicate charges. Silent errors that nobody noticed until a customer complained. And every time, someone would say ‘we should have tested that’, but there was never time.”
The tools existed, but they asked too much. Writing comprehensive tests takes time developers don't have. Static analysis catches syntax issues but misses logic problems. Code review depends on humans spotting what humans wrote.
Shailendra wanted something different: A tool that requires almost nothing from developers but can predict what will break when real users hit the new code.
What HyperTest Actually Does
The idea is simple: Take the requests that worked fine yesterday and run them against today's code changes. If something breaks, you find out before it reaches production.
This reliability has driven massive adoption. HyperTest now works with India's top 5 fintech and e
-Commerce companies, safe - guarding the critical infrastructure that powers millions of daily trans actions.
HyperTest captures real production traffic and replays it during code review. But unlike traditional testing, it doesn't just check if the code runs, it analyzes what happens at runtime. It sees the database queries, the API calls, and the business logic execution.
This Lets It Catch Problems That Static Tools Miss Entirely:
A PR that breaks an API contract, meaning the mobile app will crash when it hits that endpoint. Error handling logic that got accidentally removed, causing payments to fail silently. Race conditions that only appear under specific timing, like the one that could have drained accounts.
“Most code review tools look at what you wrote,” Shailendra explains. “We look at what happens when it runs.”
The IIT Foundation
Shailendra graduated from IIT Bombay in 2010. Ask him what he took away from those years and he doesn't mention courses or credentials.
“It’s the confidence,” he says. “Being around people who had started companies, who had taken real risks, it made you believe there’s no ceiling. You walk out thinking your job is to build something that matters.”
He credits the informal learning culture, the late night conversations with seniors, the alumni who would take calls from strangers just because they shared a campus.
When he moved to San Francisco two years ago to find early design partners for Hyper Test, he connected with IIT alumni within days.
“There’s an IIT chapter in almost every city. People want to help. That network carried me when I was just showing up with an idea and asking for feedback.”
How He Leads
Shailendra's management philo-sophy is short: Give people

People want to be part of something that matters. Create space for them to contribute meaningfully and you’ll get commitment that no salary or perk can buy

How He Leads
Shailendra's management philo-sophy is short: Give people
ownership and get out of their way.
“I’ve watched culture fall apart when people are micromanaged. The best work happens when someone owns their decisions, when they’re not waiting for permission or approval at every step.”
His advice to young Founders is similar: Focus on making people feel useful.
“People want to be part of something that matters. Create space for them to contribute meaningfully and you’ll get commitment that no salary or perk can buy.”
What Drives Him
Shailendra doesn't talk about vision state ments or five-year plans. He talks about problems.
“I’m not trying to build an image or chase some predetermined destination. I just want to solve things. Find a real problem, build a practical tool, deliver value. That’s the loop.”
He stays current through disciplined reading, a personal ecosystem of trusted sources built over years. No doom scrolling, no chasing clicks.
“Information flows from everywhere now. The skill is knowing what holds up over time versus what’s noise.”
Outside Work
When he's not building HyperTest, Shailendra reads and plays outdoor sports. His favorite books, Tuesdays with Morrie and The Courage to be Disliked, hint at how he thinks:
Relationships matter, conven - tional wisdom is often wrong, and the only approval worth seeking is your own.
His favorite travel destination is Goa. “It’s where I go to think without distractions.”
