Wow this is very cool and congrats on a big move forward, I'm actually in the process of starting my Spanish lessons just a few weeks ago. Wish you and the team the best of luck.

FYI huge demand for Spanish learning in my company (Scotiabank) as we have large operations in central and South America. So maybe once you get some critical mass of lessons corporate targets such as these may make it possible to tap into a large learner base without tons of marketing dollars.
