I just perused through the website (as someone who is diagnosed with Asperger's, now part of the ASD, and may also be underdiagnosed and need to deal with the reality of having ADHD as well), I find it highly suspect that YC would fund this company.

None of what this website claims their website does aligns with any description of CBT for ADHD I've ever seen (either from practitioners, or from good friends of mine who undergo such therapy), and also is rife with "this app helps user do things in a self-directed manner" when having an executive disfunction is at the core of ADHD(!), as if the developers behind this app have never had ADHD and didn't even bother reading Wikipedia, let alone any actual research.

The billing system seems to be incredibly predatory as well, another typical anti-pattern used by companies that try to trap people with mental disorders.

Can someone from YC actually go on record and say this is part of YC S21? I don't see it listed officially from YC anywhere.
