He shipped the software hundreds of millions of students open every morning. Then he decided the software wasn't the point. The teacher was.
At Kyron Learning, a student watches a video, gets asked a question, answers out loud in their own voice, and the teacher on screen responds the way a real tutor would, with the right follow-up at the right moment. The teacher is real. The patience to do it a million times over is the AI. That is the whole bet Rajen Sheth is making, and it is a strange one for a man who spent two decades building enterprise plumbing.
Sheth is the CEO and co-founder of Kyron Learning, a public benefit company with one stubborn idea: the single best thing that ever happens in education is one good teacher working one-on-one with one student, and almost no one can afford it. So he is using AI not to replace teachers but to let the great ones scale themselves, capturing how they question, listen, and respond, then handing that to students who would never otherwise get a tutor.
He came to this after the kind of career most people would happily retire on. He left it instead.
Use technology to level the playing field in education and bring opportunity to more students.
In 2004 he walked into a room with Larry Page, Sergey Brin, and Eric Schmidt and proposed an enterprise version of Gmail. They said no. Most people file that under failure. Sheth filed it under not yet. He reworked the idea, pitched it again, pitched it a third time, and in 2006 Google Apps for Your Domain shipped. It became Google Workspace. Today more than five million organizations run on it, and the people inside Google call him its father.
That pattern, get told no and ship it anyway, is the throughline. He led Android and Chrome for business and education. He launched the Chromebook, and then Chromebooks for Education, which is how the laptop ended up on the desk of hundreds of millions of schoolchildren who otherwise had no computer at all. He still talks about students walking up to tell him that the Chromebook was their first real access to computing.
By the end he was Vice President of Google Cloud AI and Industry Solutions, building the AI products that healthcare systems, retailers, banks, studios, and factories used to remake themselves. He had a front-row seat to the AI boom from inside one of the companies driving it. Then he got up and left the seat.
Google Apps / Workspace — the enterprise email idea Schmidt first waved off.
Chromebooks for Education — cheap, durable, and suddenly everywhere a budget was tight.
Android & Chrome for Work — the boring, load-bearing stuff that runs offices.
Google Cloud AI — industry by industry, the machine-learning toolbox.
Kyron's premise is that the magic of tutoring is in the dialogue, the back-and-forth where a teacher reads an answer and chooses what to say next. So teachers build interactive lessons, and the AI handles the listening and the timing.
A great teacher builds a lesson and anticipates how students will answer.
The learner responds out loud, in their own natural voice, like a real conversation.
The system understands the answer and picks the teacher's right response and follow-up.
One teacher's best self, available to a million students at once, one-on-one.
He grew up in Denver dreaming of quarterbacking the home team. His height filed an objection. He turned to Legos, cardboard cities, and homemade computer games instead.
His mother was the first woman to earn an electrical engineering degree in the Indian state of Gujarat. The stubbornness, it seems, is hereditary.
Widowed in 1955, his grandmother put all five of her children through college. Education as non-negotiable runs deep in the family.
He credits his sixth-grade teacher, Robert Thomasson, with showing him how one teacher can bend a life. That memory is the founding document of Kyron.
An alumnus of the Science Talent Search (1994) and the International Science and Engineering Fair in 1992, 1993, and 1994. He was building before it paid.
He overlapped at Stanford with the two students who would build Google, then later spent 17 years working for the company they started.
His first Google pitch was rejected, and he still ended up known as the father of Google Apps.
He is an American Jain whose family roots trace to Gujarat, India.
He went from putting Chromebooks in classrooms to building the AI tutoring that runs on top of that same access.
Kyron is a public benefit company, a structure that bakes the mission into the legal paperwork.
He had a VP seat at the center of the AI boom and traded it for third graders.
Persistence is his actual superpower: three pitches for Google Apps, then a product the planet runs on.
