The Indicator from Planet Money - When Uncle Sam owned banks and factories

The quintessential American economic myth is that the free market picks winners and losers. But the federal government has long had a role in this equation, from the current administration all the way back to the Great Depression. Today on the show, we uncover the history of the country's national investment bank, which shaped the relationship between the government and the market in ways that are still felt today.

Code Story: Insights from Startup Tech Leaders - The Next Iteration of Gremlin – with Kolton Andrus, CEO

Today, I'm talking with Kolton Andrus, CEO and Founder of Gremlin. You may remember previously when we spoke with Matt, the prior CTO of the company. Since that time frame, a lot has changed at the company, going through several arcs and foundational changes that are leading to not only assessing weaknesses in your infrastructure, but walking you through how to fix it (and eventually, fixing it for you).

Questions:

  • Tell us a little bit of an overview about you.
  • Your time at Amazon & Netflix were big influences on the importance of chaos engineering and reliability testing. Can you tell me what was so foundational about your time there?
  • What is next iteration of Gremlin? What has changed in the platform primarily? Tell me about the arcs of the company here.
  • In 2022, there was a leadership transition and you increased your focus on the product. What are some of the most exciting developments that came from these last 3 years?
  • Where does AI fit into Chaos Engineering? And where does it not fit? Can you unpack your viewpoint here?
  • What are you most excited about in the next chapter for Gremlin, and for the broader SRE space?
  • What advice would you give a founder just getting started?


I couldn't be more excited about the future of Gremlin. Given the arcs the company has gone through, it's evident that Kolton has built foundational layers into the platform, and is steering the ship towards responsible chaos engineering, reliability, automation and much more.

Thank you for listening to today's episode. If you'd like to learn more about Gremlin, please visit gremlin.com.
