Flint founder and CEO Sohan Choudhury on building an AI-native learning platform, raising $15 million, and why personalization—not replacement—is the real future of teaching.
INTERVIEW | by Victor Rivero
Sohan Choudhury is the co-founder and CEO of Flint, a YC-backed startup building personalized learning experiences for every student. Previously, he co-founded and served as CTO of Gatherly, a virtual events platform that grew to 250,000 users, generated $2M in revenue within months, served customers like Google and MIT, raised over $3M, and was ultimately acquired. Before that, he won Georgia Tech’s InVenture Prize with Queues and wrote for Medium, where he interviewed innovators such as Sebastian Thrun. A former Amazon engineer and college dropout, Sohan is a repeat founder obsessed with building technology that solves real problems—often at the cost of a bit more hair.
‘AI can make one-to-one, adaptive learning possible at scale—but only if it’s built with schools and for the realities of classrooms.’
Tell us about the product or service that Flint offers, and how are you different?
Flint is an AI-powered education platform transforming how students learn and teachers teach. The platform allows educators to design lessons, generate activities, and assess student progress with real-time insight while maintaining full visibility into how students use AI. Teachers can view live student sessions, track strengths and areas for improvement, and personalize instruction for every student without increasing their workload.
Students use Flint to practice languages, write essays with instant feedback, code alongside an AI collaborator, participate in guided science labs, and even create their own learning activities. Our most popular exercises have been designed by students themselves to prepare for AP exams or share study resources with peers.
Flint is AI-native, not retrofitted. It was built from the ground up with schools and educators to integrate adaptive, personalized learning directly into classroom practice. Rather than replacing teachers or adding complexity, it gives them superpowers, helping them teach the way they’ve always wanted to. As more schools join, Flint evolves into a living ecosystem where teachers share best practices, students collaborate, and the platform grows smarter with every interaction.
What inspired the start of Flint?
Flint was founded to solve a long-standing problem in education, that even the best teachers can’t fully personalize learning for every student in a class of thirty. During our own school experiences, we saw how easily students could feel left behind, disengaged, or under-challenged – not because teachers lacked skill or effort, but because the tools available to them were limited.
From a technology perspective, we recognized early that AI would inevitably reshape education. It could make one-to-one, adaptive learning possible at scale. But it was also clear that the major AI companies would not build this technology with schools or for the realities of classrooms. That was the gap in the market, and the opportunity to do things differently.

My co-founder Jinseo and I both view education as the great mobilizer. It changed the trajectory of our own families’ lives, and we wanted to make that kind of opportunity universal. We started Flint by partnering directly with schools and teachers, building side-by-side with them to ensure the platform amplified teaching rather than replaced it. Our mission is to make learning personal for every student and empower teachers to reach every learner in their classroom.
You recently raised $15 million in Series A. What does this mean for Flint, and how do you plan to use the money?
Raising $15 million in Series A funding – co-led by Basis Set Ventures and Patron – marks a major milestone in Flint’s growth. It validates both the scale of the opportunity in AI-driven education and the conviction investors have in our mission.
The funding allows us to accelerate product development, expand our engineering and customer success teams, and scale Flint from hundreds of schools to millions of students globally. We’ll deepen partnerships with networks like Cognita, which operates 110 schools that serve 95,000 students, and continue supporting educators who are integrating AI into their classrooms responsibly and effectively.
Equally important, this round gives us the resources to invest in teacher training, professional development, and AI literacy programs – making sure that adoption translates into meaningful outcomes. For us, growth doesn’t mean adding users – it means making sure every new school sees measurable improvement in engagement, performance, and teacher satisfaction. The Series A strengthens our foundation to deliver on that promise while positioning Flint as the leader in AI-native learning for the next generation.
Where do you see the biggest opportunities for AI in K-12 education over the next few years?
AI’s greatest potential in K-12 lies in personalization – making learning adapt to each student’s pace, interests, and needs without increasing the burden on teachers. For decades, educators have talked about meeting students where they are. With AI, that’s finally achievable.
In the next few years, we expect schools to shift from using AI as a novelty to embedding it in everyday instruction. AI can act as a co-teacher that provides real-time insights, scaffolds lessons, and creates differentiated materials for students at different skill levels. It can also empower students as creators – letting them design their own projects, explore new topics, and take ownership of their learning.
We also see a growing need for responsible adoption. The best opportunities will come from platforms built hand-in-hand with schools, ensuring transparency, data privacy, and teacher control. The future of AI in education is about amplification.
At Flint, we’re already seeing this transformation, where teachers use AI to individualize instruction while maintaining full visibility into how students engage, and students are learning to use AI tools responsibly to deepen their understanding. That’s the opportunity – to make classrooms smarter, more human, and more equitable.
What’s your long-term vision for Flint — and how do you see the company shaping the future of AI-driven learning?
Our long-term vision is to pioneer a new category of learning platform – one that makes today’s LMS and edtech tools feel outdated. Flint aims to become the foundation for personalized, AI-driven education worldwide, where every student has access to a learning experience tailored to their abilities and curiosity.
Over the next few years, we see Flint becoming the trusted partner for schools navigating the shift to AI. That means continuing to build technology that keeps teachers at the center, delivers measurable impact, and earns the confidence of parents and school leaders alike.

We’re especially focused on shaping how students understand and use AI. By learning with AI from an early age – ethically, transparently, and with guidance – students develop the skills they’ll need for a future where AI is everywhere.
Flint already supports hundreds of schools and over 400,000 teachers and students, and that community is growing fast. Our role is to prove that AI in education is not replacing people, but unlocking potential. If we succeed, personalized learning won’t be a privilege for a few classrooms – it’ll be a global standard.
