Things I noted:

There isn't much detail of what I get for the £s. What kind of materials? What does the curriculum cover? Do I need to purchase additional materials, or print stuff out, or what?

There isn't much background on how the materials are developed, or about who has developed them. As someone with a mild interest in pedagogy I want to know what "the latest advancements in education" means. Also, say who you are. Give a nice background story about how you were frustrated with whatever it was that drove you to create this. A personal connection is a good thing for this sort of business at this stage.

Be careful how much you emphasise the home schooled crowd. They're quite small and largely considered kooky by the mainstream.

BTW, I love the photo on the home page.

1. "Children are motivated most when they discover the meaning behind a subject of their own accord."

Not in my experience. The most motivated children are motivated for a big bag of complex reasons, including desire to please, desire to pass exams, and a general will to solve problems and answer questions. They may also be intrinsically motivated by the meaning behind a subject, but that understanding can also be provoked from outside (eg by a teacher).

2. "Children develop grit through a self-directed curriculum." Again, not in my experience. A rather harsh truth is that children develop some of their grit by not having all their natural inclinations indulged. Numerous are the tales of successful people who excelled because they overcame difficult circumstances.

It isn't clear if this site is for parents who home educate their children full time or if it is also suitable for parents whose children go to school but want to give extra support for their children at home?
