The polyglot identity

Tel Aviv has a strong polyglot tradition — Hebrew + Arabic + English are common; Russian, French, Yiddish are extensions. The Academy serves families that want all six pillars seriously, not just Hebrew + English + a token third.

Why cascading discount mattered

Pre-Koydo, families adding a third language paid 50% more than the second. The cascading discount cuts the marginal language cost; families that previously stopped at two were comfortable adding a third.

What the outcome looks like

Triple-language enrollment doubled. Quad-language enrollment (rare but real) showed up in 11 families. The Academy didn't add new students at this rate — existing families deepened. The retention math is the real win.

Hebrew + Arabic as a paired offering

The Academy's signature offering is Hebrew + Arabic together (taught with full cultural context, not just language). The Koydo cohort tooling let them run mixed Hebrew + Arabic discussion sessions where students used both languages within the same lesson. This kind of structurally bilingual lesson was clunky on the previous platform.

In their words

“Most platforms treat languages as units you buy separately. The cascading discount said: 'you're a polyglot family, here's pricing that supports that identity.' Our families noticed the difference within the first month.”
