**Gerhard Lazu:** I think that a new year is a natural time for new beginnings... And as our listeners know, we used to run all of changelog.com on Kubernetes until April 2022, when we move to something simpler; something that's all our team can be comfortable with. What I'm most comfortable with is bare metal hosts. I... |
**Andrew Rynhard:** Thank you. I'm glad to be here again. |
**Gerhard Lazu:** How are you? |
**Andrew Rynhard:** I'm doing well. It's been -- wow, that was a year ago? It feels like five years ago. |
**Gerhard Lazu:** Lots of things happened, yeah... |
**Andrew Rynhard:** A lot has happened since then. But yeah, I can't say all of them were bad. Most of them were good, so... Yeah. |
**Gerhard Lazu:** Okay. Well, we will dig into that. I won't press too hard right now, we're just getting started, but we'll dig into that. Steve, thank you for making the time to join us. |
**Steve Francis:** Yeah, my pleasure. Good to be here. |
**Gerhard Lazu:** I really appreciate all your help in the Talos community Slack. I had so many questions, and you answered some of them so well; it was super-helpful. Thank you. |
**Steve Francis:** Yeah. My pleasure. It's actually fairly unusual that I get to answer the technical questions, because -- |
**Gerhard Lazu:** I know, right? |
**Steve Francis:** ...I'm not really the technical person in the company... \[laughs\] |
**Gerhard Lazu:** So what is your role within Talos, by the way? Because our listeners don't know. |
**Steve Francis:** Yeah, so I'm the CEO. I've been with the company about two years. Before this, I founded logicmonitor.com, a SaaS-based data center monitoring service, which is where I've worked with Andrew before. |
**Gerhard Lazu:** Okay. And now you're full-time with Talos. |
**Steve Francis:** Full-time with Talos. I was one of the initial seed investors in Andrew's company, and it's just because I -- before LogicMonitor I used to run data centers myself,; I ran data centers for Citrix Online, and ValueClick, and some other big companies... So what Andrew is doing with Talos, Linux, I thin... |
**Gerhard Lazu:** Wow. Okay. I'm sure it was more than just the tech that attracted you to Talos? |
**Steve Francis:** Yes. Yes. I mean, Andrew, when I started, basically the company was Andrew and Spencer, who was basically the co-founder... And Andrew had just started. He was the lead engineer. So it was a very small company. But yeah, it was working with Andrew, and the innovation that he's bringing, and the appro... |
**Gerhard Lazu:** So what was the hook, Andrew, from your perspective? What is your side of the story? |
**Andrew Rynhard:** I don't know... I mean, I think Steve is just a nice person. \[laughter\] I thought the idea was crazy. It's a brand new Linux distribution, no Bash, no SSH... So really, Steve introduced me to another one of our angel investors, Saïd Ziouani. He was the CEO of Ansible...? |
**Steve Francis:** He was founder and CEO of Ansible. Now he's the founder and CEO of Anchore. |
**Andrew Rynhard:** That's right. |
**Gerhard Lazu:** Wow. Okay. |
**Andrew Rynhard:** So Steve put me in touch with him, and Sayid - he knows his stuff when it comes to open source; super-smart guy. And everyone just said "Okay, Sayid thinks this is a good idea", and Steve is a friend of mine, so he gave me that opportunity to talk to these people. He could have said, "No, you're jus... |
