That’s a very limited perspective. While bulk of district spend (US) is salaries, buildings, pensions, busses, cafeterias etc. there is still a substantial spend on educational materials. It’s a tiny % of the overall budget, but the larger school districts have budgets in many _billions_.

Smartboards and 3d printers etc. got popular because they came from a DIFFERENT budget - these were capital expenses.

My personal experience (ed-tech reaching ~15% of school districts) is that it is impossible to sell a solution to a district _without_ support of the teaching and learning team - i.e. teachers. And if you do, it’s impossible to get a renewal.

Lastly, 9 out of 10 startups fail. It’s not just ed-tech.
