Abhay Gupta Is Building Frizzle to Transform Math Education With AI
Most think of bankers, consultants, and corporate lawyers working 70-80 hours per week. But few think of teachers, many of whom spend hours lesson planning and grading every night after in-person classwork.
With many schools transitioning back to handwritten work to prevent students from abusing generative AI, teachers are now spending up to 10-20 hours per week manually grading alone.
Abhay Gupta grew up with a love for math education. But after witnessing teacher burnout amongst his peer group after college, he knew the education system he had enjoyed was no longer working. So he set out to leverage his expertise in development and AI to create a solution that would save teachers time while also improving students’ learning experiences.
Introducing Frizzle: AI-Powered Math Grading for Handwritten Work
Today Abhay is leading Frizzle, an AI-powered platform that grades handwritten math with on-page feedback. Teachers can simply scan worksheets or upload PDFs into the platform and receive graded work with personalized feedback in under a minute, saving up to 90% of grading time.
Although generative AI tools like ChatGPT and Claude have transformed education, the reality is that they struggle to interpret symbolic math and handwriting. Frizzle, on the other hand, was trained on a proprietary dataset containing millions of handwritten math assignments, giving it the capability to handle advanced math concepts like integrals and derivatives that ChatGPT can’t.
Frizzle also offers teachers an advanced analytics platform that can identify class-wide topic struggles and provides student-by-student performance breakdowns. Feedback can be automatically customized to match individual teacher voices and classroom approaches, enabling teachers to make more data-driven decisions while also saving time.
Abhay’s Journey to Frizzle
Abhay always had a love for math and science education, attending a specialized math and science academy in high school. After earning degrees in Computer Science, Economics, and French from Vanderbilt, he began his career working across Data Science and Product at leading tech companies Meta, Tesla, and Coinbase. But as he was pursuing exciting opportunities in tech, several friends who had become teachers after college were finding themselves overworked and burnt out, with many starting to leave teaching after just a few years.
So Abhay teamed up with co-founder Shyam Sai, who himself had built a non-profit for teaching competition math while in high school, and set out to explore ways to use AI to improve teachers’ experiences.
After getting accepted to the YC Summer ‘25 batch, the team began interviewing teachers and soon identified that grading was a major pain point in teachers’ experiences. And as most math work is handwritten, existing AI solutions weren't able to assess students’ work and provide feedback at scale.
They developed an initial solution for automating grading and launched in July of 2025. Just a few months later, Frizzle is already live in three schools with over 130 teachers using the platform every week. They’ve even become an official White House AI in Education partner.
In the long run, Abhay aims for Frizzle to bring grading and lesson planning costs to zero, enabling teachers to provide personalized learning journeys for every student.
Abhay’s Advice for Fellow Founders
Although Abhay and Shyam knew they wanted to make a change in education when they set out to build Frizzle, it wasn’t until they held hundreds of interviews with teachers that they identified grading as a major pain point.
“Knowing the problem you're solving really well and then just making sure you're talking to the people who you're helping on a regular basis is so important,” Abhay explains. “It keeps you in the loop with them on what problems they’re facing and how you can help."
But staying connected with customers isn’t just about creating a better product, Abhay notes. It also gives you the empathy to stay motivated throughout the ups and downs of the founder journey. “If you always just think about the people you're helping,” Abhay explains. “That helps you get through some of those tough moments as well.”
