Well, I'm biased... but my company offers a SasS math/science platform for middle and high school schools. We offer both instructor-led and individualized solutions.

Our students confront ambiguity, engage in real life problem-solving, overcome existing misconceptions, and (hopefully) appreciate the beauty of it all. We do this while covering the curriculum of several nations, and by using a well-supported pedagogical approach.

We actually have over nine million students around the world, but have only recently expanded to the US.

I've noticed that most-to-all of the current educational startups fail to offer a minimally viable product. Schools (and increasingly parents) will not consider products that are not properly aligned to standards. Products must additionally follow an evidence based-pedagogy. The large publishing houses sell exclusively on these two points, but completely fail at technological and educational innovation.
