The Innovators & Investors Podcast


In the latest episode of The Innovators & Investors Podcast, host Kristian Marquez sits down with Sam Huang, Principal at BMW iVentures, for a candid conversation to explore the dynamic intersection of venture capital, artificial intelligence, robotics, and manufacturing innovation. Sam shares BMW iVentures’ investment thesis, focusing on Series A and B startups across the US, Europe, and Israel, with a strong emphasis on AI-driven SaaS, automation, and onshoring trends driven by labor shortages and supply chain disruptions. Listeners gain valuable perspectives on the evolving venture diligence process, the importance of product-market fit, and how higher ARR benchmarks reflect both market maturity and macroeconomic factors like rising interest rates. Sam also candidly discusses his unconventional career path—from a Stanford history PhD program to law school and ultimately venture capital—highlighting how diverse experiences enhance investment acumen. The conversation delves into the benefits of corporate venture capital, especially BMW’s hands-on support and networking advantages for portfolio companies. Additionally, Sam reveals how AI is integrated internally at BMW iVentures to optimize workflow and decision-making. This episode is a must-listen for anyone interested in the future of innovation, investment strategy, and the transformative impact of AI and robotics on global industries.

“Our job isn’t to remove complexity, but to manage it”- Glen Murphy (as remembered by Dan) In this episode, we talk with Dan Sandler and Adam Cohen from the SystemUI team. We dip into a bit of history, talking about where things were at when they joined the team (2009-10), and how things have developed in the many years since, including how these projects and teams scaled from a single person working on it part-time to now having much larger teams doing many more things. Which kind of describes software development in general. We also talk about how to expose (or not) gestures and features in a UI system. Related: there are some bonus pro-tips on using some hidden features of System UI, as a prize for careful listeners and podcast hosts.

This time, Tor, Chet, and Romain talked with Rohit Sathyanarayana and Florina Muntenescu about the DataStore library. DataStore is the replacement for SharedPreferences, being better for many reasons (it's asynchronous and avoids blocking the UI thread, it is type-safe). It not only has a similar/simple key-value pair API like SharedPreferences, but also has more powerful API as well. It's currently in alpha, but look for it to be the recommended approach soon as it approaches stable.

Chet, Nick, Clara, Leland, Tor, Adam, and Romain. So many guests! This time, Tor, Romain, and Chet chatted with a few people on the Jetpack Compose team, about... Jetpack Compose! Compose hit Beta a couple of weeks ago (don't believe me? Check out the recent Android show on Compose Show !), so we took the opportunity to talk to some of the people that have helped build it. We talk about the current state of the library, but also about some of the design decisions that went into developing the APIs and functionality. (Note on the audio quality for this episode - it turns out that mixing so many people, all of whom recorded themselves separately using very different hardware and setups was... tricky. It's listenable, but maybe a tad below the level we shoot for. Blame the pandemic. I do.)

Allen, Chris, Adam, part of Tor, Dan (taking the photo), and Chet. All of them are also in the monitor, but backwards. Oh, and note the gym sock being used to dampen noise on the mic. High tech stuff, ADB. In this episode, Chet and Tor talk with Chris Banes, Adam Cohen, Dan Sandler, and Allen Huang about Gesture Navigation. Gesture Nav is an important UI behavior change in the Android 10 release that developers should handle and test. Chris has written Gesture Nav articles recently. This conversation goes further into the background and reasons for the change, as well as techniques for dealing with it. Note: The audio in this episode, is not up to the usual quality bar.

Chet and Romain, featuring a complete lack of Tor. In this episode, Chet and Romain talk about talking, speak about speaking, monologue monologuing.

But we all have opinions and techniques that work for us; here are some of ours.
