I am the co-founder of two fast-growing ed-tech companies, Top Hat (450 employees) and Kritik (25 employees) in Toronto, Canada. I am currently looking for a technical co-founder (in 
 Canada) and a few senior developers (could be remote, but open to relocate to Canada), and a product manager (In Canada or open to relocate to Canada) for Kritik.
At Kritik, we are changing the way students are assessed in the classrooms, moving away from objective memorization-based assessment to higher-order-thinking skills. We are in business in less than 2 years but are already in 400 college and university classrooms, generating $1M ARR.
Our technical stack is MERN and the job descriptions can be found in  <a href="
