Uncommon Thinkers 2025: Solar spacecraft, sci-fi biology, destroying PFAS, beyond AI chatbots, and better social media

On this special episode of the GeekWire Podcast, recorded backstage at the GeekWire Gala at the Showbox Sodo, we sit down with five of the inventors, scientists, and entrepreneurs selected as the Seattle region's 2025 Uncommon Thinkers, in partnership with Greater Seattle Partners. Jeff Thornburg spent years building rocket engines for Elon Musk at SpaceX and Paul Allen at Stratolaunch. Now, as CEO of Portal Space Systems, he's moved past chemical rockets to revive a concept NASA studied decades ago but never pursued — a spacecraft powered by focused sunlight. He calls it a "steam engine for space." Read the profile. Anindya Roy grew up in rural India without electricity, came to the U.S. with two suitcases and $2,000, and earned a spot in the lab of a Nobel Prize winner. Now, as co-founder of Lila Biologics, he's using AI to design proteins from scratch (molecules that have never existed in nature) to treat cancer. Read the profile. Jay Graber runs Bluesky, the decentralized social network that's become a leading alternative to X and other centralized platforms. But while most tech CEOs build moats to lock users in, Jay and the Bluesky team are building a protocol designed to let them leave. She sees the network as a "collective organism," and she's creating a tech foundation meant to outlive her own company. Read the profile. Read the profile. Kiana Ehsani came to Seattle from Iran for her PhD and spent four years at the Allen Institute for AI before becoming CEO of Vercept. She and the Vercept team are competing directly with OpenAI, Google and others in AI agents, building efficient agents that handle mundane digital tasks on computers so humans can spend less time on screens. Read the profile. Brian Pinkard spent six months after college flipping rocks and building trails because he wanted to do work that mattered. That instinct led him to Aquagga, where he's proving that the industry standard of filtering and burying "forever chemicals" is obsolete. Instead, he's using technology originally designed to destroy chemical weapons to annihilate PFAS under extreme heat and pressure. Read the profile. Eagle-eyed readers may have noticed we're missing one honoree — Chet Kittleson, co-founder and CEO of Tin Can, the startup making WiFi-enabled landline phones to help kids connect without screens. Chet wasn't able to join us, but we plan to speak with him on a future episode. With GeekWire co-founder Todd Bishop. Edited by Curt Milton.See omnystudio.com/listener for privacy information.
