The education system’s been stuck in neutral, more noise, less nuance. Then comes Flint K-12, a NY-based startup built for the real classroom, not the conference stage. Founded by Sohan Choudhury (Co-Founder & CEO) and Jinseo Park (Co-Founder & CTO), Flint just locked in a $15M Series A co-led by Basis Set Ventures & Patron, with backing from USC Viterbi, AME Cloud Ventures, Matt Pittinsky (founder of Blackboard), Afore Capital, & Y Combinator returning to double down. But this isn’t a victory lap, it’s a velocity check. In only 18 months, Flint went from 0 to 400K+ users across hundreds of schools. That’s not growth; that’s ignition.
Sohan Choudhury, the Georgia Tech Stamps Scholar who co-founded Gatherly before its 2024 acquisition, saw what happens when schools block AI instead of building with it. His old CT district banned ChatGPT, so he built Flint to give teachers a version that works for them. Jinseo Park, a former Google engineer and Forbes 30 Under 30 honoree, brought the tech edge that turned that vision into a system teachers actually trust. Flint’s AI platform lets educators generate personalized lessons, automate grading & feedback, and track real-time progress with the kind of analytics usually reserved for Wall Street dashboards. AI tutors. Speech-to-text. Coding environments. Multilanguage support in 50+ languages. Even whiteboard feedback that feels human.
The traction isn’t just domestic. Flint’s partnership with Cognita now connects 100+ schools & 95K students across 17 countries, from London to Ho Chi Minh City to Mexico City. Top schools like Nichols, Lakeside, Maret, and Strathcona-Tweedsmuir are already onboard. What gives Flint staying power isn’t the flash, it’s the foundation. The platform is COPPA, FERPA & CIPA compliant, with full admin visibility and AI guardrails that make “responsible AI” more than marketing jargon. Teachers see every move the AI makes, every interaction logged and flagged in real time.
This $15M raise isn’t about hype, it’s about scale. With Basis Set Ventures & Patron fueling the expansion, Sohan Choudhury & Jinseo Park plan to reach millions of students, deepen global rollouts with Cognita, and push new AI-powered tools built around transparency, security, and personalization. Flint isn’t chasing disruption, it’s engineering balance: teacher control, student creativity, and AI that earns its seat in the classroom.
