In This Episode
Cortex co-founders Anish Dhar and Ganesh Datta pull back the curtain on the journey of building an internal developer portal from the ground up. They share the story of the early days, when the unproven market required moving at maximum velocity to find product-market fit and win critical first deals.
The conversation explores the key moments that forced a fundamental mindset shift from prioritizing speed to engineering for enterprise-grade reliability and scale. Anish and Ganesh discuss the cultural and architectural decisions that defined this transition and offer a playbook for engineering leaders navigating today's AI-driven landscape, where the pressure to move fast is greater than ever.
You’ll learn
In the beginning, shipping features overnight was essential to learn about customers, build loyalty, and to just survive. Ganesh and Anish discuss why this was the right strategy, even though it meant accumulating significant technical debt.
Learn about the turning point when Cortex became indispensable infrastructure for its customers. This moment fundamentally changed the culture, forcing a new level of engineering discipline where downtime could cost customers millions.
Anish and Ganesh explore how investing in platform foundations and reliability evolved from a defensive necessity to a key differentiator. This focus on scale is what allows Cortex to support customers in a way competitors can’t.
The conversation covers non-obvious early choices that created long-term advantages. This includes the decisions to write tests as a three-person team and support on-prem customers from the very beginning.
Balancing speed and quality in the age of AI.
The episode closes with practical advice for engineering leaders on how to work effectively with founders. They discuss how to balance the constant push for speed with the strategic need to see around corners, manage risk, and build for the future.

"As a startup, speed is the only thing you have. When you have nothing to your name and you're just trying to figure out what customers want, speed is what gets you loyalty. It drives urgency, and that's been the cultural ethos of our company from the beginning."

"Eventually, quality and reliability become your moat. If you're trying one product and it works, and the other product crashes, which one are you going to choose? Today, our ability to be reliable is one of the main reasons people choose Cortex."

"With AI, you have entire parts of a code base written by a coding assistant. It's faster, yes, but organizations aren't doing the second-level analysis: What happens to your MTTR? How does your reliability and security posture change? That's the biggest thing SRE and platform teams are stressed about right now."

"The move to the cloud didn't replace the need for engineers; if anything, it increased the demand because more companies could be founded. More companies could take an idea and push it to the cloud. I think we're going to see the exact same thing happen with AI."

"Founders will always push for speed. A great engineering leader helps us see around corners. They’re the one who can say, 'Sure, we can ship this thing really fast. But I need you to give me room to fix this other thing, because that's going to break next.'"

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.
