If you’re looking for an uncommon thinker, how about a tech industry veteran developing and selling landline phones in 2025 — and selling out of them in the process?

Chet Kittleson is the co-founder and CEO of Tin Can, a Seattle startup making Wi-Fi enabled landline phones designed to let kids talk to friends and family with just their voices. No screens, no AI. 

GeekWire recognized Kittleson as one of our Uncommon Thinkers for 2025, a program presented in partnership with Greater Seattle Partners honoring inventors, scientists, and entrepreneurs transforming their industries in unexpected ways.

In this episode, he talks about the moment at school pickup that sparked the idea, why his own kids don’t own devices, what happened when they eliminated screens on family road trips, and the $12 million seed round led by Greylock that will fuel the company’s next chapter.

It’s a “connection factory,” not a nostalgia play. Kittleson pushes back on the idea that Tin Can is primarily about retro appeal.

“People always ask us about nostalgia and retro. … I don’t think it’s about that. I think it’s about connection,” he said. “We found a form factor that is familiar, and that’s certainly been beneficial. And people love nostalgia. … But we feel like we’re more of a connection factory than we are bringing back the bell bottoms.”

The landline was kids’ first social network — we just forgot. Kittleson grew up in La Conner, Wash., using the family phone to organize roller hockey games and playdates.

“As a social network, the landline had 100% penetration. Everybody had one,” he said. “I think we all forgot that we were major beneficiaries of that as kids.” When he mentioned this to other parents at school pickup, they all started reciting their childhood best friends’ phone numbers from memory.

Texting isn’t connection — it’s just communication. Kittleson cited a study in which stressed kids were split into three groups: one texted their mom, one called their mom, one saw their mom in person.

The kids who called or saw their mothers released oxytocin and calmed down. The texting group? “There was no chemical effect. It was like nothing happened,” Kittleson said. “It’s not connection. You are communicating, but that’s not the same thing as connecting.”

The new funding brings hardware expertise to the table. The $12 million round was led by Greylock and includes participation from David Shuman, chairman of the board at Oura, the smart ring company.

“We are a bunch of technologists with very little hardware experience,” Kittleson said. Shuman, he said, is contributing an immense amount of knowledge on supply chain, manufacturing, and cash flow.

His mom made him an uncommon thinker. When Kittleson was a kid, he wrote terrible songs. His uncle gently told him he wasn’t a great singer. His mom supported him, no matter what.

“Whatever you want to do, if you work hard enough, if you believe, if you’ve got the guts, you can do it,” she told him. That, Kittleson said, made him “more inclined to be open to the idea that I could be the reason something like the landline comes back.”

At the GeekWire Gala this week, we spent time talking backstage with five of this year’s Uncommon Thinkers — the inventors, scientists, and entrepreneurs who were selected in partnership with Greater Seattle Partners for their work transforming industries and the world. 

You can hear the full conversations on this week’s episode of the GeekWire Podcast. As I mentioned at the end, I came away with an unexpected sense of optimism. 

Jeff Thornburg of Portal Space Systems spent years building rocket engines for Elon Musk at SpaceX and Paul Allen at Stratolaunch. Now he and his team are reviving a NASA concept from decades ago: spacecraft propelled by focused sunlight.

When I asked what the world will look like “if Portal succeeds,” he made a classic entrepreneurial pivot: “When we’re successful,” he said, “we become the backbone of Earth-Moon logistics.” 

From there, he said, it’s about protecting orbits for commerce, supporting human presence on the moon, and eventually pushing out to Jupiter’s moons.

Anindya Roy of Lila Biologics is using AI to design proteins from scratch — molecules that have never existed in nature — to fight cancer. He trained in David Baker’s Nobel Prize-winning lab at UW, so he saw the before and after of machine learning’s impact on the field.

Before: success rates below 1%, ordering hundreds of thousands of designs to find one that worked. Now: 5-20% success rates, ordering a few hundred designs to find a drug candidate. 

“If you told me a couple of years ago that we can design an antibody from a computer, I would not believe you,” he said.

Jay Graber of Bluesky runs the decentralized social network that has  become a leading alternative to X. But while most tech CEOs build moats, she and her team are building a protocol designed to help users leave. 

She talks about Bluesky and the underlying AT Protocol as a “collective organism,” and describes her role as guiding and stewarding the ecosystem rather than controlling it.

The industry and the world would be better off, she says, if leaders would think about their role “more as guides and stewards, rather than just dictators or emperors as they like to style themselves.”

Kiana Ehsani of Vercept came to Seattle from Iran for her PhD, spent four years at the Allen Institute for AI, and is now competing with OpenAI and Google in the AI agent space with a fraction of their resources.

The ultimate vision is to help people move beyond mouse, keyboard, and touchscreen, letting them interact with computers the way they’d talk to a coworker.

AI agents are still early, she cautions. “Think of ChatGPT three years ago. Don’t think of it today.” Her advice for getting started with AI agents: “Start small, start with simple tasks that you don’t want to do, and then slowly build on top of it to see the magic.”

Brian Pinkard of Aquagga is tackling forever chemicals, the PFAS compounds that have spread through our water, food chain, and bloodstreams. The industry standard is to filter them out and then landfill or incinerate the waste, approaches that don’t truly solve the problem and can simply move it elsewhere.

Aquagga uses technology originally designed to destroy chemical weapons to break PFAS down into inert salts under extreme heat and pressure. Pinkard didn’t believe it was possible until he saw the data. “I’m a skeptic, I’m cynical, I’m a scientist,” he said. “I wanted to see proof.”

His bigger vision is to transform hazardous waste processing entirely. Today, huge volumes of wastewater are trucked to incinerators and burned — which he calls “thermodynamic insanity.”

Now in its third year, GeekWire’s “Uncommon Thinkers” — in partnership with Greater Seattle Partners — recognizes the inventors, scientists, technologists and entrepreneurs transforming industries and driving positive change in the world.

We met six innovators this year who are leading startups that address such things as the design of drug candidates; a throwback idea for phones for kids; a new approach to social media; elimination of harmful chemicals; spacecraft propulsion; and AI that performs computer tasks on your behalf.

Their colleagues call them “creative,” “mission-driven,” “laser-focused,” “incredibly low-ego,” and “brilliant.”

The honorees will be celebrated as part of Thursday’s GeekWire Gala in Seattle.

Catch up on our profiles of each winner below:

Anindya Roy, co-founder and chief scientific officer of Lila Biologics

• Anindya Roy’s path from a village in rural India to co-founding Seattle’s Lila Biologics is a story of persistence, curiosity, and boundary-pushing science. After training in top U.S. research labs, including the Baker Lab at the University of Washington, Roy now helps turn advanced protein-design concepts into real drug candidates — from cancer therapies to long-acting injectables — using cutting-edge computational tools. His journey highlights how unconventional thinking can drive the next wave of biotech innovation. Read more.

Chet Kittleson, co-founder and CEO of Tin Can

• Chet Kittleson is on a mission to bring back something rare in 2025: screen-free, voice-to-voice connection for kids. Tin Can‘s bright, WiFi-enabled landline phones are designed to let kids call each other or trusted contacts — no apps, no social media, no distractions. After raising $3.5 million and selling out its first two batches, Tin Can now has customers in all 50 states and across Canada. For Kittleson, every ring is a sign that parents are craving simpler, more meaningful ways for their children to connect — and that this retro-inspired hardware could be the antidote to screen overload. Read more.

Brian Pinkard, co-founder and CTO of Aquagga

• Brian Pinkard went from “flipping rocks” on trail crews in the Colorado Rockies to engineering a solution to one of the most stubborn pollution problems we face: “forever chemicals.” Now, at Tacoma, Wash.-based startup Aquagga, he’s using advanced chemistry to destroy PFAS contamination at its source. From hazardous-waste research to modular PFAS-destruction systems that have already been tested in Alaska, firefighting-foam cleanup, and municipal wastewater projects, Pinkard and his team are proving that impact-focused engineers can tackle environmental problems others call unsolvable. Read more.

Jeff Thornburg, co-founder and CEO of Portal Space Systems

• Jeff Thornburg is pushing the boundaries of what satellites can do by building a spacecraft that literally rides on sunlight. Through its flagship design, Supernova, Portal Space Systems plans to use solar-thermal propulsion to give future spacecraft dramatic, “science fiction”-style maneuverability: rapid orbital shifts, long mission lifetimes, and flexibility for both defense and commercial missions. Backed by a $17.5 million seed round and building out a large manufacturing facility in Bothell, Wash., Portal is transforming from startup vision to production-ready aerospace player — and Thornburg’s journey from SpaceX and Project Kuiper alum to leading a next-gen space venture shows just how far ambition and real engineering can take you. Read more.

Kiana Ehsani, co-founder and CEO of Vercept

• Kiana Ehsani is building AI platforms at Seattle-based Vercept not just to optimize workflows, but to give people back their time to live. With Vercept’s flagship tool Vy, her team has created a system that “sees” computer screens like a human, records workflows once, and then lets users automate tasks with a natural-language command. That means no more juggling dozens of apps, remembering shortcuts, or writing code — and more freedom to hike trails, ski mountains, or simply step away from the screen like Ehsani herself does when she’s out in nature. Read more.

Jay Graber, CEO of Bluesky

• Jay Graber is steering Bluesky not as a traditional social-network boss, but as a “pragmatic idealist” building a decentralized digital world that puts power back in users’ hands. Instead of locking content and social graphs behind proprietary walls, Bluesky is built on the open AT Protocol — meaning people can carry their posts, followers, and identity across platforms, even if the original app disappears. Graber envisions Bluesky as less a product and more a living “collective organism,” one that could become the foundation for a more open, flexible social internet. Read more.

Editor’s note: This series profiles six of the Seattle region’s “Uncommon Thinkers”: inventors, scientists, technologists and entrepreneurs transforming industries and driving positive change in the world. They will be recognized Dec. 11 at the GeekWire Gala. Uncommon Thinkers is presented in partnership with Greater Seattle Partners.

Jay Graber, CEO of the Bluesky social network, moved to Seattle during the pandemic, attracted to the region in part by the trademark gray skies, ironically. She doesn’t feel bad about staying inside and reading, writing or working on drizzly winter days.

But she also loves the outdoors. Her proudest Pacific Northwest moment: finding a matsutake mushroom under a fir tree, a species so prized that locations are treated like trade secrets.

Graber, in other words, is someone who values extraordinary things and the environments that allow them to thrive. This comes through in the tech ecosystem she oversees.

Most social networks today are walled gardens, where one company runs the servers, owns the data, and sets the rules. The AT Protocol (which Graber pronounces “at”) is an open technical standard for social media that Bluesky’s team built as the foundation for its network. Bluesky is just one app on top of it, and in theory you could move your posts and followers to another app or server with different moderation or algorithms without losing your social graph.

“The hope is that whatever happens with Bluesky — however big it makes itself — the protocol is something we hope to endure a really long time,” Graber said in a recent interview, “because it becomes foundational to not just Bluesky but a lot of apps and a lot of use cases.”

However big it makes itself. The phrase stands out in a world of tech startup leaders intent on scaling their creations toward billion-dollar exits through force of will. 

Graber instead sees Bluesky as “a collective organism,” brought to life by users, grounded in the decentralized protocol like soil on the forest floor. “I did not anticipate what Bluesky became when I started this, and so that very much makes it feel like it’s something that’s growing, that I’m overseeing, but also has a life of its own,” she said. 

Katelyn Donnelly, founder and managing partner of Avalanche, an early investor in Bluesky, first met Graber in 2022 at a small gathering of technologists, investors, and academics. What struck her: Graber was the only one in the room focused on building, not just talking. While others discussed big ideas, Graber was working through the details of how to make them real.

Later, after Bluesky’s launch, Donnelly attended a meetup in Seattle’s Capitol Hill neighborhood. Graber stayed for hours, meeting with early users, gathering feedback, and listening. 

Donnelly calls Graber “incredibly low-ego for being so young and successful.” At the same time, she isn’t afraid to be provocative, like when she wore a shirt that read, “Mundus sine caesaribus” (“a world without Caesars”) at SXSW in 2025 — styled exactly like Mark Zuckerberg’s “Aut Zuck aut nihil” (“Zuck or nothing”) shirt from a Meta event.

“You can just tell immediately that she’s never going to give up. If Bluesky failed, she’d probably build something similar again.” That’s the definition of “life’s work,” Donnelly said: everything Graber has done to date has led her to this point. 

Finding her own way

Graber was born in Tulsa, Okla., to a math teacher father and a mother who had emigrated from China. Graber’s given first name, Lantian, means “blue sky” in Mandarin. It’s a pure coincidence, given that Twitter founder Jack Dorsey would later choose the name Bluesky as a project inside the social network long before Graber was involved. 

Her mom chose the name to symbolize freedom and boundless possibility, reflecting opportunities that she didn’t have growing up in China. 

Those themes emerged early for Graber. Around age five, she resisted her mother’s structured attempts to teach her to read, running around the backyard instead. Her dad took a different approach: he brought her to the library and asked what interested her. She discovered Robin Hood, and read every version the library had, from children’s books to arcane Old English editions. The story captivated her: renegades pushing back against centralized authority.

As she continued to read, she was drawn to stories of scientific discovery, and eventually to writers who imagined new ways society could work, such as Ursula K. Le Guin.

Later, as a student at the University of Pennsylvania, Graber studied Science, Technology, and Society, an interdisciplinary major that let her explore technology from a humanistic perspective while taking computer science classes. 

After graduating in 2013, she worked as a digital rights activist, moved to San Francisco, enrolled in coding bootcamp, and worked at a blockchain startup. Later she found her way to a cryptocurrency mining operation in a former ammunition factory in rural Washington state — what she calls her “cocoon period” — where she spent long hours studying code in isolation. 

She went on to work at a privacy-focused cryptocurrency company, founded an event planning startup called Happening, and kept searching for the right environment for her own ambitions.

Origins of Bluesky

Then, in December 2019, Dorsey announced that Twitter would fund a project to develop an open, decentralized protocol for social media. He called it Bluesky. 

Twitter is funding a small independent team of up to five open source architects, engineers, and designers to develop an open and decentralized standard for social media. The goal is for Twitter to ultimately be a client of this standard. 🧵

— jack (@jack) December 11, 2019

Graber saw the thread and felt the pull. 

As detailed in an April 2025 New Yorker story, Dorsey’s team had set up a group chat to explore the idea. Graber joined and noticed the conversation was scattered — people would pop in, make suggestions, and disappear. No broader vision was coalescing. 

Graber started doing the work: gathering research, writing an overview of existing decentralized protocols, trying to provide some signal amid the noise.

By early 2021, Dorsey and then-Twitter CTO Parag Agrawal were interviewing candidates to lead the project. Graber stood out in part because she didn’t just tell them what they wanted to hear. She accepted, on one condition: Bluesky would be legally independent from Twitter.

It was a prescient demand. That November, Dorsey resigned as Twitter’s CEO. The following spring, Elon Musk began buying up shares. By October 2022, he owned the company, and promptly cut ties with Bluesky, canceling a $13 million service agreement.

Graber was on her own. But that was the point. 

“You can’t build a decentralized protocol that lots of parties are going to adopt if it’s very much owned and within one of the existing players,” she told Forbes in 2023.

‘High agency, low ego’

Today, Bluesky has more than 40 million users and a team of around 30 employees. The company has no official headquarters — fitting for a decentralized social network — though Graber and several employees work out of a co-working space in Seattle.

The platform is still far smaller than X, which reports more than 500 million monthly active users, and Meta’s Threads, which has around 300 million. Mastodon, another decentralized alternative, has about 10 million registered users. But Bluesky has grown steadily, and its open protocol gives it a different ambition — not just a destination, but the infrastructure on which others build.

Graber runs the company with what she calls a “high agency, low ego” philosophy.

“Everyone on the team exercises a lot of agency in how they do their job, and what they think the right direction is,” she said. “They try to pick up stuff that needs to be done whether or not it’s in their job description — that’s the low ego part.” 

Overall, she said, this has made for a very effective small team, although she acknowledges the trade-off: “Sometimes people have strong opinions and wander off in their own directions.” So getting people back in alignment, she said, is a big part of her job.

She describes her leadership style as collaborative rather than top-down. “I try to cultivate people’s strengths on the team and bring together a synthesis of that,” she said.

Dorsey, who sat on Bluesky’s board in the early years, is no longer involved. Ultimately, he and Graber saw things differently: Dorsey wanted Bluesky to be more purist about decentralization. Graber wanted to “catch the moment” and bring people into something accessible, even if it was somewhat centralized at the start.

“When we disagreed, he ended up just going his own way, as opposed to trying to force me to do a thing,” she said. Based on her experience, Graber said, Dorsey would hold his position and disagree, but not use his power to mandate a specific direction. 

Mike Masnick, the TechDirt founder and writer whose essay “Protocols, Not Platforms” helped inspire the project, now holds Dorsey’s board seat.

Graber describes herself as a “pragmatic idealist.” Pure idealists, she said, pursue visions that can’t work in the real world. Pure pragmatists never produce meaningful change. The key is holding both: a vision of how things could be, and the practical steps to get there.

The implications of AI

Graber sees the same dynamics playing out with artificial intelligence. The question, she said, isn’t whether AI is good or bad — it’s who controls it.

“If AI ends up controlled by only one company whose goal is power or profit maximization, I think we can anticipate that will lead to bad outcomes for a lot of people,” she said. On the other hand, if AI tools are widely available and open source, “you have this broader experimentation” — with all the chaos that entails, but also the potential for solutions that serve users rather than platforms.

She imagines a future where people might bring their own AI agents to a social network, the way Bluesky already lets users choose their own algorithms and moderation services.

“Maybe you can even run this at home in your closet,” she said. “Then you have your own AI agent that protects your own privacy, doing things for you — that’s a human empowering technology that’s working in your interest, not in the interest of a company that does not have your welfare at heart.”

She thinks a lot about historical trajectories. The printing press, she noted, ushered in a period of chaos — new technology disrupting society — followed by the construction of new institutions that made use of widespread literacy, such as universities, academic journals, and peer review.

“We’re in another period of chaos around new technologies,” she said. “We have to build new institutions that make use of everyone having access to the internet.”

The AT Protocol, in her view, could be something like that. Bluesky the company might rise or fall, narrow into a niche, or lose relevance with a new generation. But if the protocol takes hold, it becomes the foundation for something larger than any single app or company.

“If the protocol becomes widely adopted, that’s a huge success,” she said. “If people rethink how social works, and Bluesky becomes the origin point for social media to change, that’s a success.”

However big it makes itself.
