At Thinkster, were not just teaching math; were shaping lifelong learners. Our innovative approach, rooted in research-based intervention methods, ignites a passion for learning in every student. From conceptual understanding to analytical prowess, were transforming minds, one problem at a time, by tying mathematical concepts to real-life scenarios. Powered by AI, our digital worksheets analyze student errors, and we craft personalized study plans for enhanced learning outcomes. And with our companion parent app, families are empowered with real-time insights, ensuring progress never takes a backseat. But what truly sets us apart is our commitment to personalized attention. Every student receives dedicated support from a skilled math tutor and a learning plan tailored to their unique learning needs. Our world-class curriculum, meticulously aligned with state and national standards, ensures every child has the tools to thrive. But we dont stop at math. From reading comprehension to interactive games spanning math, geography, spelling, and more, were cultivating well-rounded learners equipped for success in every arena. We instill curiosity, grit, and daily learning habits that last a lifetime. We champion independent thinking, empowering students to embrace challenges with confidence. And the results speak for themselves! Thousands of students across 40 countries have experienced jaw-dropping improvements—up to 90% in just three months. But dont take our word for it—check out our rave reviews from The New York Times, The Wall Street Journal, Forbes, Fortune, Apple, NBC, CBS, ABC, Fox, PBS, Scholastic, Fast Company and many more.

Adeptmind is an AI company innovating in e-commerce search using active learning and deep learning. Its co-founders recently came out of a quite successful sale of their previous company, Maluuba This time around, they raised over $5.5 million in VC funding to date, and aim to grow a heavy-hitting, Silicon Valley-style team right here in downtown Toronto, Ontario, Canada. Over the past year, Adeptminds stock value grew 10x. We’re striving for 100% accuracy in e-commerce search out of the box. Unfortunately, no ML algorithm by itself is 100% accurate. We incorporate live human agents in our service pipeline. This human machine hybrid allows for very high accuracy and quick data bootstrapping. Our architecture makes us one of the first companies to deploy deep active learning in a consumer facing use case.
