Most people imagine a CTO spending their days planning architecture diagrams and talking about “scalability.” Sometimes that’s true. But the real job shows up when everything starts breaking at once.
One night around 11:40 p.m., I was about to shut my laptop when our monitoring alerts exploded. Error rates climbing. API requests failing. Our main dashboard looked like a Christmas tree of red warnings.
In a startup, there’s no giant operations team waiting to handle it. When things go wrong, the engineering team is the safety net.
Within minutes our Slack channels lit up. One engineer was checking database logs. Another started rolling back the latest deployment. Someone else was watching server load graphs spike in real time. Meanwhile, customers were still using the product — and we had to fix things without causing even bigger damage.
That’s the strange thing about being a CTO in a startup. Leadership during calm periods is planning. Leadership during incidents is staying calm while everyone else is racing.
I opened the system logs and noticed something odd. A small optimization we shipped earlier that day was triggering thousands of extra queries under certain conditions. It worked perfectly in testing — but real users behave differently than test data ever will.
We had two choices: patch it live or temporarily disable the feature.
Startups don’t have the luxury of endless debate during moments like this. I told the team to kill the feature flag immediately and push a quick fix. Within ten minutes the error rate started dropping. Twenty minutes later the system stabilized.
The relief in the Slack channel was instant.
Moments like that don’t show up in press releases or product announcements. Nobody outside the company even knew there had been a problem. But inside the engineering team, those nights build trust. Everyone sees who stays calm, who communicates clearly, who solves instead of panicking.
Being a startup CTO isn’t just about writing code or designing systems.
It’s about protecting the product when things break, making fast decisions with incomplete information, and keeping the team focused when the pressure spikes.
Because in a startup, technology isn’t just infrastructure.
It’s the heartbeat of the entire company — and sometimes it needs emergency care at midnight.
