In This Episode
In this episode of Braintrust, Cortex co-founder and CTO Ganesh Datta sits down with Dan Sadler, VP of Engineering at Rootly. Dan shares how building a business-critical product forced Rootly to prioritize operational maturity far earlier than most companies would, and why that discipline is now paying off as AI coding tools push incident volumes higher across the industry.
They also discuss what a genuine reliability culture looks like in practice, the specific cadences Rootly uses to stay ahead of production issues, and why Dan believes the rising pace of AI-generated code makes the infrastructure around code more important than ever.
You’ll learn
Reliability is the product, not a feature of it. If the product is down when customers need it most, nothing else you shipped matters.
A culture that prioritizes reliability is forged by what you praise and reward. Want metrics to improve? The mechanism is public recognition: Slack kudos channels, all-hands callouts, and performance reviews.
There are huge benefits to cultivating operational maturity at Series A. Building a business-critical product forced Rootly into weekly operational reviews, daily dashboard tours, canary deploys, and chaos engineering far earlier than most companies.
Dogfooding builds the empathy that drives reliability. Rootly's engineers use their own on-call product, which gives them direct motivation to improve it. That empathy is hard to manufacture when your users look nothing like you.
AI is increasing incidents, and the answer is better infrastructure around code. Rootly sees incident volumes rising as AI coding adoption grows. Automated tests, canary deploys, and automated rollbacks create confidence regardless of who wrote the code.
Quotes
"A lot of engineers have forgotten that the job is not to write code. The job is to produce business value."

"ARR is not just a sales number. ARR is engineering's metric too."

"Even if that time goes to zero, say code is now free, software delivery is still incredibly slow because we've optimized only a single portion of that pipeline."

"The demands on reliability do not go away. And if anything, they just continue to increase for us."

From IC to VP: Engineering Leadership at Every Level, with Box's Tamar Bercovici
When Tamar Bercovici joined Box, the engineering team consisted of just 30 people. In the 15 years since, she's worked through every level of the leadership track in the organization and is currently the VP of Engineering. She leads the core platform, which is the backend layer that storage, search, metadata, and Box's AI capabilities all run on.
In this episode of Braintrust, Tamar and Cortex CTO Ganesh Datta get into what the job actually requires at each level from IC to VP, why the transition to a director-level role catches people off guard in a way the manager transition doesn't, and how platform teams make the case for their value when nothing they build has a user-facing feature attached to it.

Rob Zuber on quality, metrics, and what it means to move in the right direction at CircleCI
In this episode of Braintrust, Cortex co-founder and CTO Ganesh Datta sits down with Rob Zuber, CTO at CircleCI, who has spent over a decade at the center of how engineering teams build and ship software. Rob shares his thinking on two challenges that are becoming harder to ignore as AI accelerates output: the quiet erosion of software quality, and the pressure to move fast without a clear sense of direction.
They discuss what made the best QA engineers so effective and why that mindset largely disappeared, how LLMs could help bring it back, and why engineering leaders need to think about metrics very differently depending on whether their teams are scaling a mature system or exploring uncharted territory.

The platform engineering playbook for velocity, quality, and AI readiness at SIXT
In this episode of Braintrust, Cortex co-founder and CTO Ganesh Datta sits down with Boyan Dimitrov, CEO of SIXT, one of the world's largest mobility providers operating in over 100 countries. Boyan shares the story behind SIXT's engineering transformation, from shipping software once or twice a month to running nearly 10,000 deployments a month, and explains how extreme standardization became the engine driving both velocity and quality at the same time.
They discuss the pull-and-push model SIXT uses to drive platform adoption without mandating it from the top, how Boyan built a business case for platform investment by starting with specific problems rather than a platform-first vision, and how years of foundational standardization work is now paying significant dividends as SIXT accelerates its AI strategy.
